Ingredients You’ll Need
For the Cake:
- 2 1/2 cups all-purpose flour
- 2 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1 1/2 cups granulated sugar
- 1/2 cup unsalted butter, softened
- 3 large eggs
- 1 1/2 tsp vanilla extract
- 1 1/2 cups buttermilk
- Gel food coloring (red, orange, yellow, green, blue, and purple)
For the Frosting:
- 3 cups unsalted butter, softened
- 6 cups powdered sugar
- 2 tsp vanilla extract
- 3-4 tbsp heavy cream
- Gel food coloring (matching the cake layers)
Step-by-Step Instructions
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Grease and flour six 8-inch round cake pans. If you don’t have six pans, you can bake the layers in batches.
Step 2: Mix Dry Ingredients
In a medium-sized bowl, whisk together the flour, baking powder, baking soda, and salt. Set this dry mixture aside.
Step 3: Cream the Butter and Sugar
In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy. This should take about 2-3 minutes.
Step 4: Add Eggs and Vanilla
Beat in the eggs, one at a time, ensuring each egg is fully incorporated before adding the next. Then, stir in the vanilla extract.
Step 5: Alternate Dry Ingredients and Buttermilk
Gradually add the dry ingredients mixture to the wet ingredients, alternating with the buttermilk. Start and finish with the dry ingredients. Mix until just combined; do not overmix.
Step 6: Divide and Color the Batter
Divide the cake batter evenly into six bowls. Now comes the fun part – coloring the batter! Add a few drops of gel food coloring to each bowl to create the colors of the rainbow. Remember that a little goes a long way, so start with a small amount and gradually add more until you achieve the desired hue for each layer.
- Red for the top layer
- Orange for the next layer
- Yellow for the middle layer
- Green for the next layer
- Blue for the second-to-last layer
- Purple for the bottom layer
Step 7: Bake the Layers
Pour each colored batter into its respective cake pan. Smooth the tops with a spatula to ensure an even bake. Bake the cakes in the preheated oven for 15-20 minutes or until a toothpick inserted into the center comes out clean. Remove from the oven and allow them to cool in the pans for about 10 minutes before transferring them to a wire rack to cool completely.
Step 8: Make the Frosting
While the cakes are cooling, prepare the frosting. In a large mixing bowl, beat the softened butter until creamy. Gradually add the powdered sugar, vanilla extract, and heavy cream. Beat until the frosting is smooth and fluffy. Divide the frosting into bowls and tint each one to match the colors of your cake layers.
Step 9: Assemble the Rainbow Cake
Once the cake layers are completely cooled, it’s time to assemble your rainbow cake. Place the purple layer on a serving plate and spread a thin layer of purple frosting on top. Continue layering the cake, adding a thin layer of matching frosting between each layer.
Step 10: Frost the Cake
After stacking all the layers, use the remaining frosting to cover the entire cake. You can opt for a smooth finish or create a textured effect with your spatula. Be creative and have fun with the design!
Step 11: Slice and Enjoy!
Now, the moment you’ve been waiting for – slice into your beautiful rainbow cake and revel in the colorful layers. Serve it to your friends and family, and watch their faces light up with delight.
