LEGO Cake

A child's dream: an edible building block. The base is a stable, buttery sponge (Madeira cake style) that can support heavy fondant covering. Beneath the fondant, buttercream or whipped cream insulates so the sugar paste doesn't melt from the moisture of the dough.

Instructions

1

Make the batter: cream butter with sugar, then add eggs, finally alternate flour mixture and milk.

Tip: Alternating helps maintain the emulsion so the butter doesn't separate.
2

Bake in the rectangular tin (180°C, 35 minutes), and cool completely.

Tip: You cannot put fondant on a warm cake, it will melt off.
3

Whip the double cream with the icing sugar until stiff, and coat the cake thinly.

Tip: This is the 'crumb coat', giving a smooth surface for the fondant.
4

Roll out the fondant and cover the cake.

Tip: Use icing sugar for rolling so it doesn't stick.
5

Cut small circles from the remaining fondant and stick them on top (these are the LEGO studs).

Tip: A tiny bit of water is enough for glue.

Recipe FAQ

Why did the fondant melt?
You probably put it in the fridge in a humid environment, or the cream underneath was too wet. Fondant does not like water.
