Ingredients

• 3 cups all-purpose flour
• 2 cups granulated sugar
• 1 tablespoon baking powder
• 1/2 teaspoon salt
• 1 cup unsalted butter, softened
• 1 cup whole milk
• 1 teaspoon vanilla extract
• 6 large eggs
• Gel food coloring (red, orange, yellow, green, blue, purple)
• 4 cups powdered sugar
• 1 cup unsalted butter, softened
• 1 teaspoon vanilla extract
• 3-4 tablespoons heavy cream
• Sprinkles, for decoration

Directions

1. Preheat the oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.
2. In a large mixing bowl, combine the flour, sugar, baking powder, and salt. Add the softened butter and mix until the mixture resembles fine crumbs.
3. In a separate bowl, whisk together the milk, vanilla extract, and eggs. Gradually incorporate the wet mixture into the dry ingredients, mixing well after each addition.
4. Divide the batter equally into six bowls. Add a few drops of gel food coloring to each bowl, creating six different colors for the rainbow.
5. Starting with one of the colored batters, gently pour it into the center of one of the prepared cake pans. Allow the batter to spread naturally, but avoid mixing the colors. Repeat this step with the remaining colors, layering them on top of each other in the pans.
6. Bake the cakes for 20-25 minutes or until a toothpick inserted into the center comes out clean. Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them to a wire rack to cool completely.
7. While the cakes are cooling, prepare the buttercream frosting. In a mixing bowl, beat the softened butter until creamy. Gradually add powdered sugar and vanilla extract, mixing well. Add heavy cream as needed until the frosting reaches a spreadable consistency.
8. Place the first layer of the cooled cake on a serving plate. Spread a layer of buttercream on top. Repeat with the remaining layers, stacking them up. Apply a thin layer of frosting around the sides and top of the cake to smooth out any crumbs.
9. Decorate the cake with sprinkles or any desired decorations. Place the cake in the refrigerator for at least 1 hour to allow the frosting to set.
10. Once the frosting has set, the rainbow cake is ready to be sliced and enjoyed!
