GRAVITY-DEFYING SWEETIE CAKE

Steps:

• Heat oven to 180C/160C fan/gas 4. Grease and line two 20cm cake tins with baking parchment - if your cake tins are quite shallow, line the sides to a depth of at least 5cm. Put the flour, cocoa powder, baking powder, bicarbonate of soda, sugar and 1 tsp salt in a bowl and mix well. If there are any lumps in the sugar, squeeze these through your fingers to break them up.
• Measure the buttermilk, coffee, oil and vanilla in a jug. Add the egg and whisk until smooth. Pour the wet ingredients into the dry and whisk until well combined. Pour the cake mixture evenly into the two tins, and bake for 25-30 mins until risen and a skewer inserted into the centre comes out clean. Cool in the tins for 10 mins, then turn out onto a wire rack, peel off the baking parchment and leave to cool. These sponges can be made up to three days ahead and will stay moist if wrapped in cling film, or you can wrap well and freeze for up to two months.
• To make the chocolate fudge icing, put the chocolate in a heatproof bowl, suspended over a pan of barely simmering water. Stir every now and then until melted. (Alternatively, melt in the microwave, stirring the chocolate every 20 secs so it doesn't burn.) Remove the bowl from the heat and leave to cool a little. Meanwhile, put the butter and icing sugar in another large bowl and mash with a spatula to combine (this will prevent you covering the work surface in icing sugar), then whisk with a hand mixer until smooth. Sift in the cocoa and pour in the melted chocolate and milk, then mix again until smooth.
• Use roughly half the icing to sandwich the cakes together on a cake stand or board. Use a palette knife to cover the entire cake with the remaining icing - don't worry about being too neat. Use the chocolate fingers to cover the sides of the cakes - do this straight after icing as the icing will set after a while, and the chocolate fingers won't stick.
• Melt the remaining 50g chocolate in the microwave or in a small bowl suspended over a pan of gently simmering water. Leave to cool until the chocolate is a spreadable consistency. You can speed this up by putting it in the fridge - just stir it every 5 mins or so to prevent the chocolate from setting.
• Push a skewer into the centre of the cake and slip the straw over the top - this will give it more stability. Push 1-2cm of the straw into the cake. Use a cutlery knife to spread a blob of chocolate onto a Smartie and, starting at the base, stick the Smarties to the straw. You will have to do this in stages to allow the chocolate to set a little before adding another layer of Smarties. Work your way up the straw until it's completely covered. If the chocolate in your bowl becomes too firm, simply heat again until it is at the correct consistency. Stop when you reach the bend in the straw.
• Stick the remaining skewer into the top of the straw so that it pokes out at an angle. Place the paper bag on top - you may have to use a little sticky tape to hold it in place. If any of the straw is exposed, cover it with more Smarties.
• Tip the remaining Smarties on top of the cake to flood the surface. Will keep well stored in an airtight tin for 2 days.

CHOCOLATE LAYER CAKE WITH SWISS BUTTERCREAM AND GANACHE

Steps:

• Make the cake: Preheat the oven to 350˚ F. Butter and flour two 9-inch round cake pans and line the bottoms with parchment paper. Put the cocoa powder and chocolate in a medium bowl. Add the boiling water and whisk until the chocolate is melted. Whisk in the sour cream until smooth; let cool to room temperature.
• Whisk the flour, baking soda and salt in a medium bowl; set aside. Beat the butter, granulated sugar and brown sugar in a large bowl with a mixer on medium-high speed until fluffy, 3 to 4 minutes. Add the eggs, one at a time, then the vanilla, beating well after each addition. Reduce the mixer speed to low. Beat in the flour mixture in 3 additions, alternating with the cocoa mixture in 2 additions. Finish mixing gently with a rubber spatula, scraping the bottom and sides of the bowl.
• Divide the batter evenly between the cake pans. Tap the pans against the counter to eliminate any air bubbles. Bake until the cakes spring back in the center when gently pressed, 35 to 40 minutes. Let the cakes cool in the pans for 10 minutes, then run an offset spatula around the edges and turn out the cakes onto a rack to cool completely. Remove the parchment.
• Make the frosting: Bring a few inches of water to a simmer in a medium saucepan over medium heat. Whisk the egg whites, granulated sugar and salt in the bowl of a stand mixer. Set the bowl over the saucepan (do not let the bottom of the bowl touch the water); cook, whisking, until the sugar dissolves, the egg whites are frothy and the mixture is warm, 3 to 5 minutes.
• Transfer the bowl to the stand mixer and beat with the whisk attachment on medium-high speed until stiff glossy peaks form and the mixture cools to room temperature, about 5 minutes. With the mixer running, add the butter a few pieces at a time, waiting for them to incorporate before adding more. (The mixture will become liquidy, then it will get thick and shiny once the butter emulsifies. It may also look curdled as you add the butter. It's OK: Keep adding butter and beating.) Add the vanilla and beat until combined and fluffy, 3 to 5 more minutes.
• Cut each cake in half horizontally to create 4 layers. Place 1 layer on a cake stand or serving plate. Spread about 2/3 cup frosting on top, then repeat with the remaining cake layers, spreading more frosting in between them. Spread a thin layer of frosting on the top and sides of the cake (this is the crumb coat - it doesn't have to be perfect), then refrigerate until the frosting sets, about 30 minutes. Spread the remaining frosting all over the top and sides of the cake, smoothing it with a bench scraper.
• Make the ganache: Heat the heavy cream in a saucepan over medium-high heat until steaming, then pour over the chocolate in a small heatproof bowl. Let sit for 5 minutes, then stir until smooth. Set aside until cool but still pourable, 20 to 40 minutes (the time will vary depending on the temperature and bowl). Pour the ganache on top of the cake and spread with a small offset spatula, letting it drip down the sides. Let the ganache set 20 to 30 minutes before slicing.

CHOCOLATE SHEET CAKE

Steps:

• For the cake: Preheat the oven to 350 degrees F.
• In a large bowl, combine the flour, sugar and salt. Stir together and set aside.
• In another bowl, mix the buttermilk, baking soda, vanilla and eggs. Mix with a fork and set aside.
• In a medium saucepan, melt the butter and add the cocoa. Whisk together to combine. Meanwhile, bring 1 cup water to a boil. When the butter is melted, pour the boiling water in the pan. Allow to bubble for a moment, then turn off the heat. Pour the chocolate mixture into the flour mixture. Stir together for a moment to cool the chocolate, then pour in the egg mixture. Stir together until smooth, then pour into an ungreased jelly roll pan (or rimmed baking sheet) and bake for 20 minutes.
• While the cake is baking, make the icing: Melt the butter in a saucepan over medium-low heat. Add the cocoa powder and stir until smooth. Add the milk, vanilla and powdered sugar. Stir together. Dump in the pecans and stir until well combined.
• Immediately after removing the cake from the oven, pour the warm icing over the top. You'll want to avoid doing much spreading, so try to distribute it evenly as you pour.
