Pre-heat oven on gas mark 4. Grease five 6inch cake tins with butter and line with baking parchment.
Add all the ingredients to a bowl and mix until fully incorporated the pour the mixture equally into the tins.
Bake for 15 minutes until golden. Once out the oven, leave to cool in the tins for a few minutes.
Beat the butter until pale and fluffy then add the icing sugar gradually until fully incorporated. Then add the vanilla extract and milk then mix until incorporated.
Using a palette knife, spread the buttercream on to your first layer of the cake then sprinkle honeycomb pieces on top. Repeat this until your cake is fully assembled.
Once you have your 'tower', apply the buttercream to the cake and using a spreader, spread the buttercream all the way around the cake until the cake is covered.
Add the last little bit of buttercream into a piping bag and pipe roses to the top of the cake then add some more honeycomb to the top.
