OLD FASHIONED CHOCOLATE ROLLS

Steps:

• 1. In large mixing bowl, combine flour, salt, and shortening with pastry blender until mixture is crumbly.
• 2. Gradually add water until dough forms and holds together.
• 3. Prepare filling in small saucepan. Melt margarine and stir in cocoa and enough sugar to make a spreading consistency paste. Leave pan on lowest heat and stir occassionally while completing rolls.
• 4. Separate dough into small handfuls. Roll into a ball and then flatten on floured surface. Roll out to form a thin round crust.
• 5. Place a heaping tablespoon of chocolate mixture on the dough and spread to within about 3/4 in. of outside edge of the dough. Roll dough up lengthwise and seal up the ends and fold them over to the top.
• 6. Place on ungreased cookie sheet. Repeat until all dough is used.
• 7. Bake at 375 degrees for 25 min. or until crust is lightly browned.

CHOCOLATE ROLL-OUT COOKIES

Steps:

• Sift first 5 ingredients and cinnamon, if desired, into medium bowl. Stir chocolate in metal bowl set over saucepan of simmering water until melted and smooth. Set aside. Using electric mixer, beat butter in large bowl at medium speed until smooth and creamy, about 2 minutes. Add sugar and beat until mixture is pale and fluffy, about 2 minutes. Add egg; beat until well blended, about 1 minute. Reduce speed to low and beat in vanilla and chocolate. Add flour mixture and beat on low speed just to blend. Gather dough into ball; divide in half. Form each half into ball and flatten into disk. Wrap disks separately in plastic and chill until firm, at least 4 hours. DO AHEAD: Can be made 2 days ahead. Keep chilled. Let stand at room temperature 30 minutes before rolling out.
• Position rack in center of oven; preheat to 350°F. Line 2 baking sheets with parchment paper.
• Working with 1 disk at a time, roll out dough between 2 sheets of waxed paper to 1/8-inch thickness for smaller (2-inch) cookies and 1/4-inch thickness for larger (3- to 4-inch) cookies. Using waxed paper prevents you from adding too much flour, which will make the cookies tough.
• Using decorative cookie cutters, cut out cookies. Cold dough is much easier to work with. If it gets warm as you're cutting out the cookies, place the dough-waxed paper and all-in the freezer for about 5 minutes.
• Use an offset spatula to peel away the excess dough and transfer the cookies to parchment-lined baking sheets, spacing 1 inch apart. Gather scraps, roll out dough, and cut more cookies, repeating until all dough is used. If not icing cookies, decorate with sprinkles or other sugar toppings, if desired.
• Bake 1 sheet at a time until cookies are firm on top and slightly darker around edges, about 9 minutes for smaller cookies and up to 12 minutes for larger cookies. Line baking sheets with fresh parchment as needed. Cool completely on rack. Decorate cookies with royal icing if desired. DO AHEAD: Cookies can be made 4 days ahead. Store between sheets of waxed paper in airtight containers.

CHOCOLATE SWISS ROLL

Steps:

• Pre-heat the oven to 220° C/gas mark 7/428°F
• Mix the eggs and sugar with an electric whisk until it is thick and frothy and it leaves a trail. Sift in the cocoa and flour then fold them in.
• Line a tray with greaseproof paper and pour in the chocolate Swiss roll mix spread it out so it is even. Then cook in the oven for 10 minutes.
• When you take it out of the oven roll it up in a tea towel so that when it cools it does not crack when you roll it.
• Melt the Nutella and spread it on the chocolate Swiss roll before you put the whipped double cream on it. If you wanted raspberry's randomly place them on the laid out Swiss roll and when you roll it up you can decorate how you like.

CHOCOLATE SWISS ROLL

Steps:

• Preheat the oven to 325 degrees F (165 degrees C). Spray a jelly roll or sheet pan with cooking spray and line with parchment paper.
• Sift flour, cocoa, salt, and baking soda together in a medium bowl.
• Beat eggs and sugar in another bowl with an electric mixer on high speed until tripled in volume, about 5 minutes. Add 1/2 teaspoon vanilla extract. Beat in dry ingredients on low speed in thirds, alternating with melted butter, until just combined. Pour into the prepared pan (the thickness should be less than 1/4 inch).
• Bake in the preheated oven until a toothpick inserted into the center comes out clean, 8 to 9 minutes. Allow to cool completely.
• Flip cake upside-down out of the pan onto a new sheet of parchment paper. Remove the used parchment paper from the top of the cake gently. Roll cake, starting at one end of the paper, into a tube until it is completely rolled into the parchment. Refrigerate for 2 hours.
• Whip cream, powdered sugar, and vanilla extract together in a bowl. Mix in chocolate-hazelnut spread. Roll out the cake and spread filling evenly. Roll up the cake with the filling, keeping in mind that the cake might crack or tear easily.

CHOCOLATE SWISS ROLL CAKE (REGULAR & MINI)

Steps:

• Preheat oven to 350°F (177°C). Spray a 12×17 inch baking pan with nonstick spray or grease with butter, so the parchment paper sticks. Then line it with parchment paper so the cake seamlessly releases. Spray or grease the parchment paper too. We want an extremely nonstick surface for this cake roll.
• Using a hand mixer or a stand mixer fitted with whisk attachment, beat the egg whites and 1/3 cup (67g) granulated sugar together in a medium bowl on high speed for 5 minutes or until stiff peaks form. Set aside. In another bowl, beat the egg yolks, remaining sugar, and vanilla extract together until pale and creamy, about 2 minutes.
• Sift the flour, 3 Tablespoons cocoa powder, baking powder, and salt together into a large bowl bowl. Pour the melted butter, coffee, and egg yolk mixture over the dry ingredients. Beat everything together on medium speed until completely combined. Using a rubber spatula or wooden spoon, gently fold in the egg whites until completely combined. Avoid over-mixing and deflating those whites. Batter will be very light.
• Spread batter evenly into prepared pan. It will be a very thin layer. Shimmy the pan on the counter to smooth out the top. Bake for 10 minutes or until the top of the cake gently springs back when touched with your finger. Do NOT over-bake.
• As the cake bakes, place a piece of parchment paper (larger than the cake) or a thin kitchen/tea towel flat on the counter. (Note: I find a kitchen towel is better to help prevent cracking.) Using a fine mesh sieve, dust parchment/towel with 2 Tablespoons of cocoa powder. Once the cake comes out of the oven, quickly run a knife around the edges to loosen it. Immediately invert it onto the parchment/towel. Peel off the parchment paper that was on the bottom of the cake as it baked. Starting with the narrow end, begin tightly rolling the hot cake up with the parchment/towel. Do this slowly and gently. The cake will be warm. Allow the cake to cool completely rolled up in the parchment/towel. Feel free to place it in the refrigerator to speed it up, about 3 hours and up to 1 day. (Note that you must bring it back to room temperature before unrolling, so make sure you set aside enough time.)
• Bring cake to room temperature if it was in the refrigerator. The cake is prone to cracking if unrolled while cold.
• Using a hand mixer or a stand mixer fitted with a whisk attachment, whip the heavy cream, sugar, and vanilla extract on medium-high speed until medium to stiff peaks form, about 2-3 minutes. Then beat in the marshmallow creme, if using.
• Slowly and gently unroll the cake. Spread whipped cream evenly on top, leaving about a 1/2 inch border around the cake. Gently roll the cake back up, without the parchment/towel this time. Place on a wire rack set on a baking sheet (to catch the extra ganache). Set aside on the counter or in the refrigerator as you prepare the ganache.
• Place chopped chocolate and corn syrup, if using, in a medium bowl. Heat the cream in a small saucepan until it begins to gently simmer. (Do not let it come to a rapid boil- that's too hot.) Pour over chocolate, then let it sit for 2-3 minutes to gently soften the chocolate. Slowly stir until completely combined and chocolate has melted.
• Pour ganache all over cake roll. Feel free to spoon up any dripped ganache and spoon over the cake again. Refrigerate for at least 30-60 minutes before slicing and serving.
• Cover leftover cake and store in the refrigerator for up to 3 days.

CHOCOLATE SWISS ROLL CAKE

Steps:

• To make the chocolate cake, preheat the oven to 425ºF. Place a piece of parchment paper or a silicone mat on a 17x12 sheet pan, and rub butter on it to grease.In a large bowl, whisk to combine the cocoa powder, flour, and salt.Bring an inch of water to a simmer in a medium saucepan. Combine the eggs and sugar in a heatproof glass bowl, then place over the simmering water (make sure the water doesn't touch the bowl). Using a hand mixer, beat the eggs and sugar together over medium speed for about two minutes, until the eggs are thick, pale yellow, and warm to the touch (if you have a thermometer, you want the eggs to be about 120ºF. If you don't have a thermometer, just touch the mixture with your finger every once in a while until it feels like hot tap water). Remove the egg bowl from the heat and continue beating at medium high speed for another 3 minutes, until it's thick and airy, and has reached the ribbon stage. That means when you drag and drizzle a spoonful of the liquid, it shouldn't settle back into the liquid for a good 5-10 seconds. Mix in the melted butter.Add the dry ingredients to the mixture, and gently fold it into the eggs with a spatula, working quickly. Spread the batter onto the buttered parchment or silicone mat, leaving an inch from the edges. Bake the cake for 5-6 minutes, until springy to the touch.Place a piece of parchment paper on a flat surface and sprinkle lightly with cocoa powder. Flip the cake onto the parchment, then remove the parchment or silicone mat that the cake baked on. Gently roll the cake up into a log while it's still warm. This is like muscle memory for the cake, and it will roll easier again later.To make the filling, combine the heavy cream, sugar, and vanilla extract in a large bowl, and whip with a hand mixer to stiff peaks, about 5 minutes on medium speed. Unroll the cooled cake, then spread the cream all over, leave a 1-inch border around all edges. Roll the cake up gently (leaving the parchment paper behind), then place on a wire rack.To make the chocolate ganache, microwave the cream and chocolate in a heatproof bowl in 30-second intervals, stirring after each time, until combined. Add the tablespoon of milk, which will give a more pourable consistency. Pour the chocolate ganache evenly over the cake, then refrigerate for 20 minutes before serving, so the ganache can firm up.The cake is now ready to be sliced and served. Enjoy!

CHOCOLATE ROLLS

Steps:

• Two 12 by 17-inch baking sheets, lined with parchment paper
• Place the yeast, warm water and 1/4 teaspoon sugar in a large bowl. Stir with a fork to dissolve the yeast and allow it to stand for about 3 minutes.
• Whisk the unbleached flour, cocoa powder, the remaining 1/3 cup sugar and the salt together in a medium bowl. Set them aside.
• Using your hand, stir the coffee, the egg yolk, and the butter into the dissolved yeast. Gradually add the flour mixture, stirring until a shaggy mass forms and all of the flour is moistened.
• Move the dough to a lightly floured surface and knead for about 7 to 8 minutes, until it is silky smooth and elastic. This dough should be nice and moist, so add flour sparingly as you work. Shape the dough into a loose ball cover it with plastic wrap and let it rest for about 10 minutes to relax the gluten strands.
• Flatten the dough and stretch it gently with your fingers to form a rectangle about an inch thick. Spread the chocolate chips evenly over the rectangle. Fold the dough into an envelope and knead gently for 2 to 3 minutes, until the chips are well distributed. The dough should be soft, smooth, and springy. If the dough resists, let it rest for 5 minutes and then continue kneading it. Some of the chips may pop out of the dough, but they can easily be incorporated again after the first rise when the dough has softened.
• Shape the dough into a loose ball and place it in a lightly oiled bowl. Turn to coat the top of the dough with oil, and cover the bowl tightly with plastic wrap. Let rise at room temperature (75 to 77 degrees F) until the dough has doubled in volume, about 2 hours.
• Line two 12 by 17-inch baking sheets with parchment paper. Gently pour the dough onto the floured work surface pressing any loose chocolate chips into dough. Flour your hands lightly divide the dough into 12 equal pieces (each weighing about 2 1/2 ounces). Shape the pieces into rolls and place 6 on each prepared baking sheet leaving several inches between the rolls so they won't grow together as they rise. Cover them loosely with oiled plastic wrap and let them rise at room temperature until doubled in volume, about 45 minutes to 1 hour.
• While the bread is proofing make a cornstarch wash: Put the cold water in a small saucepan and whisk in the cornstarch. Bring to a boil, stirring frequently until it thickens. Remove from the heat and cover to keep a skin from forming. Set aside to cool.
• About 15 minutes before you're ready to bake, place one oven rack in the top third of the oven, and another in the bottom third, and preheat the oven to 400 degrees F.
• When the buns have doubled, use a pastry brush to paint them with a thin coating of the cornstarch wash. Brush gently so you don't deflate them. Place one pan on each oven rack. Using a plant sprayer, immediately mist the top and sides of the oven 6 to 8 times and quickly close the oven door. Repeat this misting procedure two more times at 1-minute intervals.
• Bake for 10 minutes, then reduce the oven temperature to 350 degrees F and rotate the pans from top to bottom and front to back to ensure even baking. Bake for 10 to 15 minutes longer, or
• until the tops of the buns feel firm but not hard when you press them slightly, and the bottoms are very lightly browned. These rolls should have a thin soft covering, not a hard crunchy crust. Remove from the oven and use the pastry brush to paint the top of each bun quickly and evenly with the cornstarch wash. Transfer the rolls to a rack and allow them to cool before serving. These are best eaten the day they are baked.

CHOCOLATE ROLL

Steps:

• Preheat the oven to 350 degrees F.
• Grease a 9 1/2 by 13 1/2 by 3/4-inch pan. Cut waxed paper width of pan plus 5 inches in length. Line the pan so there is at least 2 inches of waxed paper extending over both ends of the pan. Grease the paper.
• Separate the eggs, and beat the yolks with the sugar, until they are light, creamy and thickened.
• Break chocolate into pieces and place in medium saucepan with the water. Melt over hot (not boiling) and let cool.
• Using clean beaters, beat the egg whites until stiff. Stir the chocolate into the yolks and fold in the beaten egg whites. Gently combine. To facilitate this, put a small amount of whites into the yolk and chocolate mixture and then add all this back into the whites.
• Spread the chocolate mixture evenly in the prepared pan and bake for 10 to 15 minutes. Shut off the oven and bake 5 minutes more. Practice will tell you if the timing is right.
• Remove from the oven and cover top with a dishtowel wrung out in cold water. Stretch the cloth tight and tuck under the pan. Cool, and refrigerate 1 hour.
• Remove the cloth carefully and loosen edges with knife. Dust top heavily and completely with cocoa. Lay 2 pieces of waxed paper longer than the pan side by side overlapping with the top over the bottom. Turn out cake on bottom end of paper and carefully pull off the waxed paper.
• Whip the cream over a bowl of ice, and add the sugar and vanilla when it begins to thicken. Beat until stiff.
• Spread the cake with the whipped cream, with less towards the top. Roll the cake from bottom, the long side forward, using the waxed paper to roll it. When rolled, the paper should be all around it so you can mold it with your hands as you finish. Put on a long wooden board to chill for a few hours.
• When ready to serve, open the paper and cut off along side with the tip of a knife. If there are cracks along the side, dust all over with the cocoa in a shaker or use a small sieve or sifter to distribute it where needed.

• I add some chopped chocolate bits to the cool whip sometimes for a change.

CHOCOLATE SWISS ROLL

Steps:

• Heat the oven to 220C/200C fan/gas 7. Line a 22 x 32cm swiss roll tin (if it's 20 x 30cm that's still fine) with baking parchment. Sift the flour and cocoa powder together into a bowl and set aside.
• Crack the eggs into another bowl or the bowl of a stand mixer and tip in the sugar. Use an electric whisk or the whisk attachment to beat the eggs and sugar together for 5 mins until pale and very thick. Use a spoon or spatula to gently fold in the flour mixture until completely incorporated and everything's the same colour with no streaks.
• Gently scrape the mix into the tin and spread to the corners. Bake for 9-10 mins until puffed up and springy to touch. While the cake is baking, get another piece of parchment a little larger than the tin and scatter it with sugar. When the sponge is cooked, use oven gloves to carefully invert it onto the sugar-coated paper. Lift off the tin and peel away the top layer of parchment. Score a line 2cm from one of the shorter edges, then use the parchment to roll the sponge into a spiral with the parchment running through it. Leave the rolled sponge to cool completely.
• While the cake is cooling, make the filling by whisking all the ingredients together until the cream stiffens. Unroll the sponge and spread over the filling, leaving the scored edge clear. Starting from the scored edge, use the parchment to roll the sponge up around the filling. Lift onto a board or serving platter and dust with icing sugar. Can be served straight away or chilled for up to 24 hrs. Serve in slices.

CHOCOLATE SWISS ROLL CAKE

Steps:

• Sift the dry ingredients: Into a large bowl, sift together the cake flour, cocoa powder, and cornstarch three times. Set the dry ingredients aside.
• Warm sugar in the oven while it preheats: Line the half-sheet pan with parchment paper, then sprinkle the sugar onto the paper in an even layer. Place the pan in the oven. Set the oven to 400°F. You'll have the sugar in the oven while it preheats and remove it from the oven when it is warm to the touch, in step 4.
• Whisk the eggs in a stand mixer: While the sugar is warming, use a stand mixer fitted with the whisk attachment to lightly beat the eggs, at low speed, until they look foamy with small bubbles, for 30 to 45 seconds.
• Sift cocoa powder over a tea towel: Lightly dust a clean tea towel by sifting the cocoa powder over it.
• Whip the heavy cream: Pour the heavy cream into a mixing bowl. Use an electric hand mixer fitted with the whisk attachment. Set it to medium speed for 2 minutes or until the beater leaves behind ribbons in the cream.
• Unwrap and glaze the chocolate swiss roll: Remove the swiss roll from the fridge and remove the plastic covering. Place the roll on a cooling rack set over a sheet pan. Pour the ganache over the top of the roll and use an offset spatula or the back of a spoon to cover the roll evenly in the chocolate. If you want to double the ganache, to use up all of the ganache, scoop up the excess from the pan underneath and repeat the pouring steps. Transfer the cake to a platter and refrigerate it until the ganache feels slightly tacky to the touch, or 20 minutes.
