Ingredients
Before we dive into the baking process, let’s gather all the ingredients you’ll need to create your own rainbow cake masterpiece. Here’s what you’ll need:
For the Cake:
- 2 1/2 cups all-purpose flour
- 2 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs
- 2 teaspoons vanilla extract
- 1 1/2 cups whole milk
- Gel food coloring in rainbow colors (red, orange, yellow, green, blue, and purple)
For the Frosting:
- 3 cups unsalted butter, softened
- 6 cups powdered sugar
- 2 teaspoons vanilla extract
- 3-4 tablespoons milk
- Gel food coloring in a color of your choice (for frosting the outside)
Now that you have all your ingredients ready, let’s move on to the step-by-step instructions.
How to Make a Rainbow Cake: Step-by-Step
Step 1: Prepare Your Baking Equipment
Start by preheating your oven to 350°F (180°C). You’ll need three 8-inch round cake pans for this recipe. Grease the pans with butter or non-stick cooking spray, and line the bottoms with parchment paper for easy cake removal.
Step 2: Mix Dry Ingredients
In a medium-sized bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this dry mixture aside for now.
Step 3: Cream Butter and Sugar
In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture becomes light and fluffy. This typically takes about 2-3 minutes with an electric mixer.
Step 4: Add Eggs and Vanilla
Beat in the eggs, one at a time, making sure each egg is fully incorporated before adding the next. Then, mix in the vanilla extract.
Step 5: Alternate Dry Ingredients and Milk
Gradually add the dry mixture to the wet ingredients, alternating with the whole milk. Start and finish with the dry ingredients, mixing until just combined. Be careful not to overmix, as this can make the cake tough.
Step 6: Divide and Color the Batter
Now comes the fun part! Divide the cake batter into six equal portions. Using gel food coloring, tint each portion with a different color of the rainbow: red, orange, yellow, green, blue, and purple. Stir until the colors are well incorporated and vibrant.
Step 7: Bake the Layers
Pour each colored batter into a separate cake pan. Smooth the tops with a spatula to ensure even baking. Place the pans in the preheated oven and bake for approximately 20-25 minutes, or until a toothpick inserted into the center of each cake comes out clean.
Step 8: Cool and Frost
Remove the cakes from the oven and allow them to cool in the pans for about 10 minutes. Then, carefully remove them from the pans and place them on a wire rack to cool completely.
While the cakes are cooling, you can prepare the frosting. In a separate bowl, beat together the softened butter, powdered sugar, vanilla extract, and milk until you achieve a smooth and creamy consistency. You can also tint the frosting with a color of your choice for the outside of the cake.
Step 9: Assemble the Rainbow Cake
Once the cake layers are completely cooled, it’s time to assemble your rainbow cake. Place one colored layer on a serving plate or cake stand and spread a layer of frosting on top. Continue to stack the colored layers, adding frosting between each one.
Step 10: Frost the Outside
Apply a thin layer of frosting to the outside of the cake to create a “crumb coat.” This helps seal in any loose crumbs. Refrigerate the cake for about 30 minutes to set the crumb coat. Then, apply a final layer of frosting to the outside, making it as smooth and even as possible.
Step 11: Decorate and Enjoy!
Now, let your creativity shine! You can decorate your rainbow cake with sprinkles, edible glitter, or any other decorations you like. Slice into your masterpiece and savor the delightful layers of color and flavor.
Baking a rainbow cake is not just a culinary endeavor; it’s a joyful and artistic experience that results in a delicious, eye-catching dessert. Whether you’re celebrating a birthday, a special occasion, or simply want to add some color to your day, this vibrant cake is sure to bring happiness to all who enjoy it. So, unleash your inner baker, create your own rainbow masterpiece, and share the magic of a rainbow cake with your loved ones. It’s a sweet and colorful journey worth taking!
