Ingredients

• 2 cups all-purpose flour
• 2 teaspoons baking powder
• 0.5 teaspoon baking soda
• 0.5 teaspoon salt
• 1 cup granulated sugar
• 0.5 cup unsweetened applesauce
• 0.5 cup low-fat sour cream
• 4 egg whites
• 1 teaspoon vanilla extract
• 0 as needed food coloring (red, orange, yellow, green, blue, purple)
• 8 ounces low-fat cream cheese
• 1 cup powdered sugar

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and flour 6 8-inch round cake pans, or use parchment paper to line the pans.

Step 2

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

Step 3

In a separate bowl, combine the granulated sugar, unsweetened applesauce, low-fat sour cream, egg whites, and vanilla extract. Beat on medium speed with an electric mixer until well combined and smooth.

Step 4

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid over-mixing.

Step 5

Divide the batter evenly into 6 smaller bowls. Add a few drops of food coloring to each bowl to achieve the desired shades of red, orange, yellow, green, blue, and purple. Stir until the color is uniform throughout.

Step 6

Pour each colored batter into its respective prepared cake pan, spreading it evenly.

Step 7

Bake for 20-25 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then remove from pans and cool completely on wire racks.

Step 8

For the frosting, beat the low-fat cream cheese until smooth, then gradually add the powdered sugar until the mixture is creamy and spreadable.

Step 9

Once the cakes are completely cool, assemble the cake by layering the colors in order, spreading a thin layer of cream cheese frosting between each cake layer.

Step 10

Finish by frosting the top and sides of the cake with the remaining cream cheese frosting.

Step 11

Slice and serve your beautiful low-fat rainbow cake!
