Ingredients
Scale
- 2 ½ cups all-purpose flour
- 1 ½ cups granulated sugar
- 1 cup unsalted butter, softened
- 4 large eggs
- 1 cup whole milk
- 2 teaspoons vanilla extract
- 4-6 food coloring gels (red, orange, yellow, green, blue, purple)
- 1 teaspoon baking powder
- ¼ teaspoon salt
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- 2 teaspoons vanilla extract
- 2-3 tablespoons milk
- Optional rainbow sprinkles for decoration
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour six 8-inch round cake pans.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- In a large bowl, beat the softened butter and sugar until light and fluffy.
- Add eggs one at a time, then mix in vanilla extract.
- Gradually add dry ingredients in three parts, alternating with milk, starting and ending with dry ingredients.
- Divide batter equally into six bowls and add different food coloring gels to each, mixing well.
- Pour each colored batter into the prepared pans and bake for 20-25 minutes until a toothpick comes out clean. Cool completely on wire racks.
- Spread frosting on top of each cake layer and carefully stack to build the rainbow cake.
- Cover the entire cake with vanilla frosting and decorate with rainbow sprinkles or additional accents. Optional: add themed decorations for extra flair.
Notes
- Ensure all layers are completely cooled before frosting to prevent melting.
- Use gel food colors for vibrant, lasting colors without thinning the batter.
- Decorate with sprinkles immediately after frosting for best adhesion.
