Cars cake

The top tier of novelty cakes: here the sponge must be dense enough to be carved ('Madeira' type cakes), but soft enough to enjoy. Under the fondant covering, buttercream insulates, protecting the sugar paste from the cake's moisture. This cake is both a game of patience and sculpture.

Instructions

1

Make the sponge: cream the butter with the sugar, add the eggs, then alternate adding the dry ingredients and milk. Bake in a rectangular tin at 180°C for 35 minutes.

Tip: A denser butter sponge holds its shape better during carving than a light sponge.
2

Cool completely (best if left in the fridge overnight). Carve out the car shape with a knife.

Tip: Cold sponge crumbles less and can be carved much more precisely.
3

Make buttercream (butter+icing sugar whisked until fluffy). Coat the cake thinly (crumb coat), chill, then coat again smoothly.

Tip: This layer seals in crumbs and provides a smooth, adhesive surface for the fondant. Do not use whipped cream!
4

Roll out the red fondant on a surface dusted with cornflour, and cover the cake. Smooth it with your hands.

Tip: Cornflour prevents sticking but doesn't melt in like icing sugar.
5

Create details (wheels, windscreen) from the other colours and stick them on with a little water or edible glue.

Tip: Water dissolves sugar, acting as glue, but use sparingly so it doesn't get soggy.

Recipe FAQ

Why did the fondant melt?
You probably used whipped cream underneath. Fondant (sugar) melts with moisture. Always seal the cake with buttercream or ganache before covering!
Why did the fondant bubble up?
Air got trapped underneath. Prick it with a needle and smooth out the air.
