Simple Steps to Make a St. Patrick’s Day Rainbow Cake from Scratch

If you’ve been worried that making a rainbow cake from scratch is too complicated, you’ll be happy to know it’s easier than it looks! The recipe starts with a basic vanilla cake batter, which you can make from scratch or use your favorite recipe.

Once your batter is ready, divide it into bowls and add food coloring to each section to create the vibrant rainbow layers. I recommend using Americolor food coloring gels for the best results—these colors are vibrant and won’t water down your cake batter.

Layering the Cake

The fun part of making a rainbow cake is layering the colored batter. For a clean, layered look, carefully pour each colored batter into your bundt cake pan. Avoid swirling the layers, as you want to keep them distinct and colorful. Want a fun swirl design? I recommend trying a swirl bundt cake pan to get a gorgeous pattern every time.

Baking and Frosting the Rainbow Cake

Once the cake layers are poured into the pan, bake according to the recipe instructions. After the cake has cooled, it’s time to add the finishing touch: melted cream cheese frosting. Drizzle it generously over the top to bring all the colors together and create a smooth, creamy topping.

This rainbow cake from scratch doesn’t require any complicated frosting techniques—just a simple drizzle of cream cheese frosting will do the trick. It’s a light and fluffy topping that complements the rich, colorful layers perfectly.

Basic White Cake Recipe

Ingredients
  

  • 2 1/2 cups all purpose flour
  • 2 1/2 tsp baking powder
  • 1/2 tsp salt
  • 1/2 cup unsalted butter softened
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tbsp vanilla extract
  • 1 cup whole milk

Instructions
 

  • Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper.
  • Mix dry ingredients: In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
  • Cream butter and sugar: In a large bowl, beat the softened butter and sugar together with an electric mixer on medium speed until light and fluffy, about 3-5 minutes.
  • Add eggs and vanilla: Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  • Add dry ingredients and milk: Add the dry ingredients in three parts, alternating with the milk. Start and end with the dry ingredients. Mix until just combined; do not overmix.
  • Bake: Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
  • Cool: Allow the cakes to cool in the pans for about 10 minutes. Remove from the pans and transfer to a wire rack to cool completely before frosting.
