CHOCOLATE-RASPBERRY LAYER CAKE

Steps:

• For the puree: Place the raspberries in a blender and blend until smooth (yields 1 1/4 cups of puree). Remove 1/4 cup of puree and reserve.
• For the cake: Place an oven rack in the center of the oven. Preheat the oven to 325 degrees F. Butter and flour the bottom and sides of two 8- or 9-inch round nonstick baking pans. Set aside.
• Place 1 tablespoon of the cake mix and the chocolate chips in a small bowl. Toss until the chocolate chips are coated.
• In a large bowl, combine the remaining cake mix, 1 cup of the raspberry puree, vegetable oil, eggs and 1/4 cup water. Using an electric hand mixer, blend on low speed for 30 seconds. Increase the speed to medium and beat for 2 minutes, scraping the bottom and sides of the bowl with a spatula as needed. Mix in the chocolate chips. Divide the batter between the prepared pans and bake until a cake tester inserted into the center of the cakes comes out clean, 30 to 35 minutes.
• Cool the pans on a wire rack for 15 minutes. Remove the cakes from the pans and cool completely on a wire rack, about 1 hour.
• For the frosting: In a large bowl, combine the powdered sugar, cocoa powder, butter, cream cheese and sour cream. Using an electric hand mixer, beat on low speed until smooth. Increase the speed to high and beat until light and fluffy, about 1 minute.
• In a small bowl, mix together 3/4 cup of the frosting and the reserved 1/4 cup puree until smooth.
• To assemble the cake: Place one cake layer, flat side-up, on a cake stand. Using a spatula, spread the raspberry-chocolate frosting over the cake layer leaving a 1/2-inch border. Place the other cake layer on top. Frost the top and sides of the cake with the remaining chocolate frosting. Decorate with fresh raspberries or chocolate curls. Using a damp knife cut the cake into wedges and serve.
• Cake can be made 1 day in advance. Refrigerate in an airtight plastic container. Allow the cake to stand at room temperature for 1 hour before serving.

CHOCOLATE & RASPBERRY ZEBRA CAKE

Steps:

• Heat oven to 180C/160C fan/gas 4. Grease and line the base of a deep 22cm round cake tin with baking parchment.
• To make the raspberry sponge, put the yogurt, oil and raspberries in a food processor or blender, and whizz until well blended. Sieve, to remove the seeds, into a measuring jug, until you reach 300ml. Discard the rest.
• From now, make the 2 cakes simultaneously. In 2 mixing bowls, separately mix the dry ingredients, plus a pinch of salt, for the raspberry and chocolate sponges. Crack in the eggs, then add the yogurt, oil and vanilla extract to the chocolate one, and the measured raspberry mixture to the other. Beat each with an electric whisk until smooth, cleaning whisks between bowls. Quickly stir some pink food colouring into the raspberry batter, to give a strong colour - a good cherry pink works well.
• Sit the cake tin in front of you and a bowl of cake batter to each side - you need to work quickly and smoothly for the next bit, so make sure your oven is hot and racks are in the right place. Using 2 x ½ cup measurers, or 2 similar ladles or serving spoons, spoon 1 measure (about 150ml) of the chocolate batter into the very centre of the prepared cake tin. Don't wait for it to settle or spread, quickly top with the same measure of raspberry mixture, right in the middle (see Secrets of success, below). Repeat alternating batters, without pausing, until all the mixes are finished, then put straight in the oven.
• Bake for 1 hr until a skewer poked into the middle comes out clean - keep an eye on it though, you may want to loosely cover with parchment after 45 mins if the cake is looking dark (the top will be cracked). Cool in the tin.
• To decorate, put the cream and raspberry jam in a pan, and bring nearly to the boil, stirring to melt the jam. Take off the heat, tip in the chocolate and leave until melted. Stir together until smooth. When thick enough to spread, remove the cake from the tin and swirl the chocolate icing all over the top.

CHOCOLATE & RASPBERRY BIRTHDAY LAYER CAKE

Steps:

• Heat the oven to 180C/160C fan/gas 4. Oil and line two round 20cm springform cake tins with baking parchment. Whisk the oil, sugar, eggs and milk in a bowl until smooth. Sieve the flour, cocoa and bicarb into another large bowl, then gradually mix in the wet ingredients.
• Divide the mixture between the tins and bake for 35-40 mins until the cakes are risen and spring back when pressed. Leave to cool in the tins for 10 mins, then transfer to a wire rack to cool completely.
• For the raspberry layer, stir the jam and the defrosted raspberries together. Once the cakes are cool, whip the cream with the sugar to soft peaks, then gently fold half the raspberry mixture through the cream to create a ripple effect.
• Spoon most of the reserved raspberry mixture over one of the cakes, then dollop on half of the cream. Smooth over with a palette knife, then place the other sponge on top. Swirl over the remaining cream and swirl the last of the raspberry mixture through it. Will keep in the fridge for two days.

CHOCOLATE-AND-VANILLA ZEBRA CAKE

Steps:

• Cake: Preheat oven to 350 degrees. Brush two 9-inch round cake pans with butter. Line bottoms of pans with parchment rounds; brush parchment with butter.
• Whisk together flour, baking powder, and salt until thoroughly combined, 30 seconds. In a large bowl, whisk together egg whites and granulated sugar until light, opaque, and foamy, about 2 minutes. Whisk in 1 1/2 cups milk, butter, oil, and vanilla until smooth. Add flour mixture; whisk until smooth. In another large bowl, whisk together egg yolks, 1/3 cup milk, and cocoa. Add 3 1/4 cups of vanilla batter to cocoa mixture and whisk until smooth. Whisk remaining scant 3 tablespoons milk into remaining vanilla batter.
• Spoon 1/4 cup vanilla batter into center of each prepared pan. Spoon 1/4 cup chocolate batter into each center, directly on top of vanilla batter. Repeat, always spooning batter into centers of pans, and occasionally tapping pan firmly on work surface to ensure even distribution, until all batter is used (batters should appear as concentric rings).
• Bake, rotating pans halfway through, until cakes are puffed slightly and a tester inserted into centers comes out clean, 35 to 40 minutes. Transfer pans to a wire rack; let cool 10 minutes. Turn cakes out onto rack, remove parchment, and let cool completely.
• Frosting: Meanwhile, whisk together cocoa, espresso powder, salt, hot water, and vanilla until a smooth paste forms. Beat butter with confectioners' sugar on medium-high speed until light and fluffy. Beat in chocolate, then cocoa mixture and corn syrup, until smooth.
• Trim tops of cakes flat. Transfer one cake, trimmed-side up, to a cake plate or stand lined with parchment strips. Spread 3/4 cup frosting evenly over top. Place remaining cake layer on top, trimmed-side down. Spread remaining frosting evenly over top and sides of cake. Remove parchment strips; serve. Cake can be stored, uncovered, at room temperature up to 12 hours, or refrigerated, uncovered, up to 2 days; bring to room temperature before serving.
