📝 Instructions

16 steps
1

Preheat your oven to 350°F (175°C) and grease six 8-inch round cake pans or bake in batches if you have fewer pans.

2

In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

3

In a large bowl, cream the butter and sugar together using a hand or stand mixer until light and fluffy, about 3-4 minutes.

4

Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.

5

Alternate adding the dry ingredients and milk in batches, beginning and ending with dry ingredients. Mix just until combined; do not overmix.

6

Divide the batter evenly into six bowls. Use a digital scale for accuracy, if desired.

7

Add a few drops of each food coloring to separate bowls of batter, creating red, orange, yellow, green, blue, and purple batter. Stir until colors are vibrant and evenly incorporated.

8

Pour each colored batter into its prepared cake pan and smooth the tops with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.

9

Let the cakes cool in their pans for 10 minutes, then turn them out onto wire racks to cool completely.

10

To make the frosting, beat the softened butter until creamy, about 2 minutes. Gradually add the powdered sugar and beat until smooth.

11

Add the heavy cream and vanilla extract to the frosting and beat until light and fluffy. Add more cream if needed for a spreadable consistency.

12

To assemble the cake, level the tops of each cake using a serrated knife or cake leveler, if needed.

13

Place the purple layer on a cake stand or plate. Spread a thin layer of frosting on top. Repeat with the blue, green, yellow, orange, and red layers, frosting between each.

14

Apply a crumb coat (thin layer of frosting) over the entire cake and chill for 30 minutes.

15

Spread the final layer of frosting over the cake. Smooth with an offset spatula and decorate as desired.

16

Slice and serve this stunning rainbow cake, and enjoy!
