Ingredients

1. 2 ½ cups all-purpose flour
2. 2 ½ tsp baking powder
3. ½ tsp salt
4. 1 cup unsalted butter, softened
5. 2 cups granulated sugar
6. 4 large eggs
7. 1 tbsp vanilla extract
8. 1 cup whole milk
9. Gel food coloring (red, orange, yellow, green, blue, purple)
10. For frosting: 2 cups butter, 6 cups powdered sugar, 2 tsp vanilla, ¼ cup milk

Substitution Options

• Use almond or coconut milk instead of whole milk for a dairy-free option.
• Swap butter for margarine if needed.
• Try natural food coloring like beet juice or turmeric for a healthier twist.

Step 1: Preparing Your Batter

Start by preheating your oven to 350°F. In a bowl, whisk together the flour, baking powder, and salt. In another bowl, cream the butter and sugar until fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla. Alternate adding the dry ingredients and milk to the wet mixture, starting and ending with the dry mix. Pro tip: Make sure your butter is softened but not melted—it makes a world of difference!

Step 2: Adding the Colors

Divide the batter evenly into six bowls. Use gel food coloring to tint each portion—red, orange, yellow, green, blue, and purple. Gel coloring works best because it won’t thin out your batter. Mix each color thoroughly. Pro tip: If you want brighter shades, don’t be shy with the coloring!

Step 3: Baking the Layers

Pour each colored batter into greased cake pans. Pop them into the oven for about 15-20 minutes or until a toothpick comes out clean. Let the layers cool completely before assembling. Chef’s tip: Freeze the cooled layers for 10 minutes before frosting—it prevents crumbs from messing up your design.

Timing

Prep time: 30 minutes | Baking time: 20 minutes per batch | Resting time: 1 hour | Total time: About 2 hours

Chef’s Secret

To get sharp edges on your frosting, chill the frosted cake for 15 minutes before serving. This trick locks everything in place!

Extra Info

Did you know that rainbow cakes symbolize unity and diversity? Each color represents different aspects of life coming together harmoniously. How cool is that?

Necessary Equipment

• Mixing bowls
• Stand mixer or hand mixer
• Cake pans (round or square)
• Spatula
• Offset knife for frosting

Storage

Store your rainbow cake recipe 4 layers in an airtight container at room temperature for up to two days. For longer storage, keep it in the fridge. Just make sure to bring it back to room temperature before serving—it tastes better that way!

If you live in a warm climate, refrigeration is key. Frosting can soften quickly, ruining your hard work. Wrap individual slices in plastic wrap for easy grab-and-go treats.

Freezing is also an option. Wrap the cake tightly in plastic wrap and foil, then freeze for up to three months. Thaw overnight in the fridge before enjoying.

Tips and Advice

Make sure your layers are even. Uneven layers can lead to lopsided cakes. Use a kitchen scale to divide the batter equally. Also, always sift your powdered sugar before making frosting—it ensures a smooth texture.

Presentation Tips

• Add edible glitter for extra sparkle.
• Top with fresh berries for a pop of natural color.
• Use piping bags to create decorative borders.

Healthier Alternative Recipes

1. Gluten-Free Rainbow Cake: Swap regular flour for almond or oat flour.
2. Vegan Rainbow Cake: Replace eggs with flaxseed meal and butter with coconut oil.
3. Low-Sugar Option: Use monk fruit sweetener instead of sugar.
4. Paleo-Friendly Cake: Try cassava flour and honey.
5. Dairy-Free Version: Use plant-based milk and vegan butter.
6. Protein-Packed Cake: Add protein powder to the batter.

Mistake 1: Overmixing the Batter

Overmixing leads to dense cakes. Mix just until combined. A few lumps are okay—they’ll disappear during baking. Practical tip: Use a spatula for the final fold to avoid overworking the batter.

Mistake 2: Using Liquid Food Coloring

Liquid coloring can alter the batter’s consistency. Stick to gel-based options for vibrant colors without compromising texture.

Mistake 3: Skipping Cooling Time

Assembling a warm cake causes the frosting to melt. Always let your layers cool completely—or chill them briefly—for a flawless finish.
