- Why did the fondant melt?
- You likely used whipped cream underneath. Fondant (sugar) melts with moisture. Always seal with buttercream or ganache!
- Why are there bubbles in the fondant?
- Air got trapped. Prick with a pin and smooth it out.
Race Car Birthday Cake
The king of shaped cakes: here the sponge must be dense enough to carve ('Madeira' style) but soft enough to enjoy. Under the fondant, buttercream acts as a sealant, protecting the sugar paste from the cake's moisture. This cake is part patience, part sculpture.

Instructions
1
✓
Make the sponge: cream butter and sugar, add eggs, then alternate dry ingredients and milk. Bake in a rectangular pan at 350°F (180°C) for 35 minutes.
Tip: Dense butter cakes hold their shape better for carving than light sponge cakes.
2
✓
Cool completely (best if chilled overnight). Carve the car shape with a knife.
Tip: Cold cake crumbles less and allows for precision carving.
3
✓
Make buttercream (whip butter and confectioners' sugar). Crumb coat the cake thinly, chill, then coat again smoothly.
Tip: This layer seals in crumbs and provides a sticky surface for fondant. Do not use whipped cream!
4
✓
Roll out red fondant on a cornstarch-dusted surface and cover the cake. Smooth with your hands.
Tip: Cornstarch prevents sticking but doesn't melt in like sugar does.
5
✓
Create details (wheels, windshield) from other colors and attach with a little water or edible glue.
Tip: Water dissolves sugar, acting as glue, but use sparingly or it will get soggy.
