Ingredients

• 4 cups All-purpose flour
• 2 tablespoons Baking powder
• 1 teaspoon Salt
• 1.5 cups Unsalted butter (softened)
• 3 cups Granulated sugar
• 10 large Egg whites
• 2 teaspoons Vanilla extract
• 1.5 cups Whole milk
• 6 colors Gel food coloring (red, orange, yellow, green, blue, purple)
• 6 cups Confectioners' sugar
• 16 ounces Cream cheese (softened)
• 1 cup Heavy cream

Directions

Step 1

Preheat the oven to 350°F (175°C). Grease and line six 8-inch round cake pans with parchment paper.

Step 2

In a large bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.

Step 3

In the bowl of a stand mixer fitted with the paddle attachment, cream the softened unsalted butter and granulated sugar on medium speed until light and fluffy, about 3-4 minutes.

Step 4

Gradually add the egg whites to the butter mixture, one at a time, mixing well after each addition. Mix in the vanilla extract.

Step 5

Reduce the speed to low and alternately add the flour mixture and whole milk, starting and ending with the flour mixture. Mix just until combined.

Step 6

Evenly divide the batter into six separate bowls. Add a different gel food coloring to each bowl: red, orange, yellow, green, blue, and purple, stirring each until the color is evenly distributed.

Step 7

Pour each colored batter into the prepared cake pans. Smooth the tops with a spatula.

Step 8

Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center of the cakes comes out clean.

Step 9

Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 10

While the cakes are cooling, prepare the cream cheese frosting by beating the cream cheese and confectioners' sugar in a large bowl until smooth. Slowly add the heavy cream and continue beating until the mixture is fluffy and spreadable.

Step 11

Once the cakes are completely cooled, spread a thin layer of frosting between each layer, stacking the cakes in rainbow order.

Step 12

Frost the outside of the cake with the remaining cream cheese frosting and smooth out with a spatula. Decorate as desired.

Step 13

Refrigerate the cake for at least 30 minutes before serving to set the frosting. Slice and enjoy!
