Rainbow cloud cake
Wow guests with this stunning cloud cake for a birthday celebration. The celestial decorations are made with marshmallows twisted into cloud-like shapes
- Serves: 14 persons
- 4ripe bananas (330g peeled weight)
- 250ml sunflower oil
- 400g golden caster sugar
- 400g self-raising flour
- 1tsp baking powder
- 300g butter, plus extra for the tin
- 700g icing sugar, sifted
- 100g soft cheese
- 200g canned salted caramel sauce
- blue food colouring gel
- large and medium white marshmallows (ensure vegetarian if needed)
- rainbow, balloon and cloud cake toppers (optional)
Step 1Heat the oven to 200C/180C fangas 6. Butter three loose-bottomed 20cm sandwich tins and line with baking parchment. Mash the bananas. Tip into a food processor with the oil, eggs, sugar, flour and baking powder, and pulse to combine. Divide between the tins, then bake for 25-30 mins. Cool in the tins for 10 mins before turning out onto a wire rack to cool fully.
Step 2For the buttercream, beat the butter and sugar in a stand mixer until pale, then beat in the soft cheese. Level the tops of the cakes using a serrated knife. Put one of the cake layers on a board and spread with half the caramel, repeat with a second cake layer and sandwich together with the final one. Use a palette knife to spread a thin layer of buttercream all over the cake. Put in the fridge to chill for 30 mins.
Step 3Set aside a small bowl of plain buttercream, then divide the rest between three bowls and colour them different shades of blue. Use the back of a spoon to spread the buttercreams over the cake, then use a palette knife to loosely blend together, creating a watercolour effect. Chill for 10 mins.
Step 4Use a cutlery knife to create clouds on the side using the plain buttercream. Twist the marshmallows into cloud-like shapes and place on top of the cake. Finish with the cake toppers, if using. Will keep chilled for up to three days.
