Barbie Dome Cake

For the cake: Preheat the oven to 170°C (150° fan) | 325F | gas 3. Prepare the cake batter and spoon into a greased pudding bowl.

Bake for 40 - 50 minutes until a cake tester comes out clean from its centre. Remove to a wire rack to cool.

Once cool, use a wide spatula to help turn out the cake from the bowl. Trim the top side flat with a serrated knife and sit the flat side on a cake stand.

For the buttercream: Gently beat together the buttercream with a few drops of food colouring until uniformly pink. Spoon most of the buttercream into a piping bag fitted with a small star-shaped nozzle.

Cover the cake with a thin layer of the remaining buttercream. Chill for 15 minutes. Pipe roses of buttercream all over the sides of the cake, leaving the top undecorated for now.

Using a small thin skewer, bore two holes down through the top of the cake, approximately 4 cm | 1.5" width apart. Pass the legs of the doll down through the holes so that her body is sitting on top of the cake.
