Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup (226g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup (240ml) whole milk, room temperature
  • ½ cup rainbow sprinkles (non-melting, high-quality)
  • Gel food coloring in red, orange, yellow, green, blue, and purple
  • For the Frosting:
  • 1 cup (226g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 2 tsp vanilla extract
  • 24 tbsp heavy cream or milk
  • Pinch of salt

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour your cake pans or line them with parchment paper circles to prevent sticking.
  2. In a medium bowl, whisk together 2 ½ cups flour, baking powder, and salt. Set aside.
  3. Using your mixer, beat the softened butter and sugar together on medium speed for about 4-5 minutes until fluffy and pale.
  4. Beat in the eggs one at a time, making sure each is fully incorporated before adding the next. Stir in the vanilla extract.
  5. With the mixer on low, add the flour mixture in three parts, alternating with the milk (start and end with flour). Mix just until combined after each addition.
  6. Gently fold in ½ cup rainbow sprinkles with a spatula, being careful not to overmix.
  7. Divide the batter evenly into six portions in separate bowls.
  8. Add a few drops of gel food coloring to each bowl to create red, orange, yellow, green, blue, and purple batters. Stir gently until evenly colored.
  9. Pour each colored batter into its prepared pan, smoothing the tops with a spatula.
  10. Bake for 18-22 minutes, or until a toothpick inserted comes out clean.
  11. Let cakes cool in pans for 10 minutes, then remove to cooling racks to cool completely.
  12. For the frosting, beat softened butter on medium speed until creamy. Gradually add powdered sugar, then vanilla, salt, and cream. Beat until light and fluffy, adjusting cream for desired consistency.
  13. Assemble the cake by placing the purple layer on a cake stand or plate. Spread a thin layer of frosting on top, then stack the blue layer. Repeat layering with green, yellow, orange, and red, frosting between each.
  14. Apply a crumb coat and chill for 15 minutes. Then add a final thick coat, smoothing with an offset spatula.

Notes

Use gel food coloring to avoid thinning the batter and to keep colors vibrant. Toss sprinkles in a little flour before folding in to prevent color bleeding. Divide batter evenly using a kitchen scale for uniform layers. Chill cake between frosting steps for a smooth finish. If batter is too thick after coloring, add a splash of milk.
