Ingredients

Scale

2 ½ cups cake flour
1 ½ cups granulated sugar
1 tablespoon baking powder
½ teaspoon salt
1 cup unsalted butter (softened)
5 large eggs (room temperature)
1 cup whole milk (or buttermilk)
Gel food coloring (red, orange, yellow, green, blue, purple)

For the vanilla buttercream

1 cup (226 g) unsalted butter, softened
4 cups (480 g) powdered sugar, sifted
2 tbsp whole milk
1 tsp vanilla extract

Instructions

Preheat your oven to 350°F (175°C) and grease three round cake pans.
In a bowl, whisk together the cake flour, sugar, baking powder, and salt.
In another bowl, cream the softened butter until fluffy; gradually mix in the dry ingredients.
Add eggs one at a time followed by the milk; mix until smooth.
Divide the batter into six bowls; color each portion with different gel food colors.
Pour the colored batters into prepared pans and bake for 25-30 minutes or until a toothpick comes out clean.
Allow cakes to cool completely before frosting with your favorite icing.
Make the vanilla buttercream: beat the softened butter for 3 to 4 minutes until pale and fluffy. Add the sifted powdered sugar a cup at a time on low speed, then the milk and vanilla. Beat 2 minutes more, until light and spreadable. Frost only once the bake has cooled completely.
