MARY BERRY'S MANHATTAN ROULADE RECIPE - (4.2/5)

Steps:

• Grease two (13 x 19-inch) Swiss roll tins then line the tins with non-stick baking parchment. In a large bowl, with an electric mixer on full speed, beat the egg whites until soft peaks form. Gradually sprinkle in 75 grams (2 1/2 ounces) sugar, beating until the sugar completely dissolves and the whites stand in stiff peaks. Heat the oven to 190°C (375°F/gas mark 5). In another large bowl, using an electric mixer, beat the egg yolks and remaining sugar until very thick and lemon-colored. Add the flour and cocoa. Beat until well mixed, occasionally scraping the bowl with a rubber spatula. With a rubber spatula or wire whisk, gently fold the beaten egg whites into the egg yolk and sugar mixture, one third at a time. Spoon the mixture into tins, spreading evenly. Bake for 8-10 minutes or until the tops of the cakes spring back when lightly touched with your finger. Sift the cocoa over 2 clean tea towels. When the cakes are done, immediately turn the cakes out onto the towels. Carefully peel the baking parchment off the cakes. If you like, cut off the crisp edges. Starting at a narrow end of each cake, roll cakes with towels, Swiss roll-style. Place the cake rolls, seam-side down, on wire racks and leave to cool completely. Meanwhile, prepare the white chocolate butter cream. In a small, heavy saucepan, heat 3 tablespoons of milk over a medium heat until tiny bubbles form around the edge of the pan. Remove the saucepan from the heat. Using a wire whisk, beat in the chopped white chocolate. Mix until the chocolate melts then stir in the coffee liqueur. Cool, then refrigerate until cold for about 30 mins, stirring occasionally. Place the icing sugar and softened butter in a large bowl. (Don't use margarine as the butter cream will separate). Using an electric mixer, beat for 10 minutes or until light and fluffy, scraping the bowl often with a rubber spatula. Gradually beat the white chocolate mixture into the butter cream until smooth, occasionally scraping the bowl with the spatula. Now, unroll 1 cooled cake and use a palette knife to spread with about one third of the butter cream. Starting at the same narrow end, roll the cake without the towel. Unroll the second cake and spread with another third of the butter cream. Next, join the cakes - along the narrow end of the second cake, place a narrow end of filled cake roll. Finally, roll the cakes together by rolling the second cake around the first cake roll. Cook's tip: When cutting roulade, it's important to slice it cleanly so that the filling is seen at its best. For perfect results, dip a long serrated knife in hot water before slicing. Wipe the blade with kitchen paper after cutting each slice and dip again in water.

CHOCOLATE BUTTERCREAM ICING

Steps:

• Put the chocolate in a heatproof bowl over a pan of barely simmering water (make sure the bowl isn't touching the water). Stir until melted. Alternatively, melt in the microwave, stirring every 30 secs. Leave the melted chocolate to cool for 5 mins.
• Mash the butter and icing sugar together with a fork first, then switch to a wooden spoon or electric beaters if you have them. Sift in the cocoa and pour in the melted chocolate, a pinch of salt and the milk, then mix again until smooth. Use to top cupcakes or cover and fill a chocolate sponge cake.
