Ingredients

• 450 grams all-purpose flour
• 15 grams baking powder
• 1 teaspoon salt
• 340 grams unsalted butter
• 400 grams sugar
• 6 pieces large eggs
• 2 teaspoons vanilla extract
• 240 milliliters whole milk
• 6 colors (red, orange, yellow, green, blue, purple) gel food coloring
• 300 grams unsalted butter (for frosting)
• 600 grams powdered sugar
• 2 teaspoons vanilla extract (for frosting)
• 60 milliliters whole milk (for frosting)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease and flour six 9-inch (23 cm) round cake pans.

Step 2

In a medium bowl, whisk together the flour, baking powder, and salt; set aside.

Step 3

In a large bowl, beat 340 grams of butter and sugar with an electric mixer until light and fluffy, about 3-4 minutes.

Step 4

Add the eggs one at a time, beating well after each addition. Mix in the 2 teaspoons of vanilla extract.

Step 5

Gradually add the flour mixture to the butter mixture in three parts, alternating with the milk, beginning and ending with the flour mixture. Mix just until combined after each addition.

Step 6

Divide the batter equally into 6 bowls. Add a different color of gel food coloring to each bowl, stirring to combine until the desired shade is reached.

Step 7

Pour each colored batter into its prepared baking pan, smoothing the tops with a spatula.

Step 8

Bake in the preheated oven for about 20-25 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 about 10 minutes, then turn them out onto wire racks to cool completely.

Step 10

For the frosting, beat 300 grams of butter in a large bowl until creamy. Gradually add the powdered sugar, beating until smooth.

Step 11

Mix in the 2 teaspoons of vanilla extract, then add the 60 milliliters of milk, beating until the frosting is light and fluffy.

Step 12

To assemble the cake, level the tops of each cake layer with a serrated knife if necessary.

Step 13

Place the purple layer on a serving plate or cake stand. Spread a thin layer of frosting on top.

Step 14

Repeat with the remaining layers in the following order: blue, green, yellow, orange, and red, frosting between each layer.

Step 15

Spread a thin layer of frosting over the entire cake to create a crumb coat. Refrigerate the cake for 15-30 minutes to set.

Step 16

Apply a final coat of frosting all over the cake, smoothing it with a spatula.

Step 17

Decorate as desired, then slice and enjoy your stunning Rainbow Cake!
