Rainbow Cake Ingredients:
- For the White Velvet Cake
- 135 gram egg whites (about 4 1/2 large egg whites)
- 240 gram milk
- 1 1/2 teaspoons vanilla
- 300 gram flour (plain)
- 300 gram sugar
- 1 1/3 teaspoons baking powder
- 1/4 teaspoon salt
- 170 gram butter, soft
- Blue icing color (I used Wilton sky blue and royal blue)
- 300-600 grams lemon curd (I used 300 grams for half a batch white velvet cake)
- Blueberries
Preheat oven to 175°C (350°F)
In a small bowl, whisk together egg whites, milk and vanilla. Set aside.
In a large mixing bowl, combine flour, sugar, baking powder and salt. Add the soft butter and mix on low speed. Add 1/3 of the egg mixture and mix until well combined. Repeat twice.
For 3 layers: Divide the batter into three bowls. In the first bowl add a tiny drop of icing color. In the second bowl add two tiny drops and so on. Use 8-inch cake pans and bake in the oven for 25-30minutes.
For 6 layers: Divide the batter into 6 bowls. In the first bowl add a tiny drop of icing color. In the second bowl add two tiny drops and so on. Stir and pour into 6-inch cake pans (about 15 cm). Bake in the oven for about 15 minutes or until a cake tester inserted into the center of each cake comes out clean
For 12 layers or 2 small cakes: Divide the batter in 12 bowls. In the first bowl add a tiny drop of icing color. In the second bowl add two tiny drops and so on. Use 4-5-inch cake pans (10-12cm) and bake in the oven for about 8-10 minutes.
Let the cakes cool in the pans for about 10 minutes. Loosen the sides with a small spatula and invert cakes onto wire racks.
Place the layer who only had one tiny drop of color on a cake plate. Spread lemon curd with a spoon or small spatula over the first layer, make sure it’s well covered . Repeat process with the layer who hade two tiny drops of color and so on. Finish with a layer of lemon curd on the top and decorate with blueberries. Enjoy it !
