Hidden Polka Dot Cake with Cadbury Mixed Buttons 

To celebrate the release of Cadbury mixed chocolate buttons, we asked Mumsnetters to create recipes for a buttons-inspired cake. The winning design? This show-stopping three-tier cake tower - with surprise polka dots hidden in every slice

Perfect for birthdays and special occasions, this super-impressive cake combines a vanilla sponge with chocolate cake pops, butter cream, heavenly chocolate ganache and - of course - chocolate buttons.


For the cake pops

100g flour 
100g caster sugar

3 medium eggs mixed together
40g plain flour

Cadbury mixed chocolate buttons


To make the cake pops

1. Heat oven to 180c. 

2. Combine dry ingredients, then add buttermilk, vegetable oil, egg and vanilla. Fold together until smooth.

3. Add coffee and mix until combined. 

4. Lightly brush cake pop mould with vegetable oil, then fill one tray with cake batter. Place the other tray on as a 'lid' and bake for 10 minutes at 180c, or until a toothpick inserted into the cake comes out clean. 

5. Allow to cool, then pop them in the freezer while you prep the sponge - this'll stop your cake pops from overbaking later. 

To make the vanilla sponge (makes one, repeat for extra tiers)

1. Heat oven to 160C. Grease a deep, 6-inch round cake tin, lining the base and sides with non-stick paper. 

2. Beat the butter, sugar, and vanilla together until it's fluffy, then pour in the eggs and mix in the yoghurt.

3. Fold the flour into the mixture, then add the milk and mix altogether.

4. Spread a thin layer of cake batter over the base of the tin followed by a layer of cake pops, then spoon the rest of the mixture evenly over the top.

5. Bake for approx 45 mins or until brown and a skewer inserted in the cake comes out clean. Leave to cool on wire rack.

To make the buttercream

1. Beat butter and icing sugar together until fluffy, followed by the vanilla paste. Add a splash of milk to help get the right consistency, if you need it.

To make the chocolate ganache

1. Heat the cream in a pan over a medium heat until steaming - but not boiling. Meanwhile, chop the chocolate and place in a glass bowl.

2. Take the pan off the heat, and add the cream to the chocolate chunks, stirring until it's melted together. 

3. Leave to firm up - it should be smooth, but spreadable!

Polka dot cake


1. Trim the top of the cakes off with a bread knife, so you've got a nice flat surface of the sponge. Then pop it on the cake stand, where you can cover the top with butter cream.

2. Repeat with the next two sponges, stacking one on top of the other, then cover the whole tower in buttercream. Place in the fridge for 10 minutes to firm up.

3. Cover the cake in chocolate ganache. Tip: heat your palette knife with a bit of boiling water, then dry it off, before you start spreading - it'll get your ganache extra smooth.

4. Decorate with Cadbury mixed chocolate buttons, using any leftover to decorate the cake stand. Devour!
