A disposable piping bag
3 cake dowels
Method
Preheat the oven to 180ºC/350ºF/Gas Mark 4
Start by making the base cake. Beat the butter and caster sugar together until pale, light and fluffy using either a free-standing mixer or an electric hand-held mixer
Gradually add the beaten eggs, a little at a time, beating well between each addition
Sift both the flours, the bicarbonate of soda and the cocoa powder into a separate bowl. In a third bowl, mix the sour cream and cream cheese together until smooth. Add half the sifted dry ingredients to the egg and sugar mixture and foldin using a large metal spoon. Then add half of the cream mixture and combine. Repeat this process with the remaining flour and sour cream and mix until smooth
Spoon the cake batter into the 25cm tin and spread level with a palette knife. Place on the middle shelf of the oven and bake for 70–80 minutes or until a skewer inserted into the middle of the cake comes out clean. Leave the cake to cool in its tin for 10 minutes before turning out onto a wire rack to cool completely. If making the day before, the cooled cake in baking parchment and foil until ready to decorate
Make the top layer by repeating the method as above with the quantities listed. Spoon the cake batter into the 15cm tin and spread level with a palette knife. Place on the middle shelf of the preheated oven for 40–45 minutes or until a wooden skewer inserted into the middle of the cake comes out clean. Leave the cake to cool in its tin for 10 minutes before turning out onto a wire rack to cool completely
To make the buttercream, beat the butter, icing sugar and vanilla extract until light and fluffy
Cover the cooled cakes with the buttercream
Place smaller cake onto a cake board then place on the centre of the larger cake
Working quickly, press the cigarillos around the outside of the cakes, cutting in half for the top layer. Add roses to finish. As an alternative to the roses, decorate with fresh, soft fruits, such as raspberries, strawberries, blueberries and redcurrants. Add the fruits at the very last minute.
