Rainbow Cupcakes

These rainbow cupcakes have a light and tender crumb. They are also very colorful, layered with colors of a rainbow. They are great for a party or other special occasion.

Ever since I saw rainbow bread at King Hawaiian Bakery in Torrance I have been thinking of nothing else. I loved the colorful bread so I couldn’t wait to try my hand at making a rainbow treat at home. Instead of bread, I wanted something sweeter so I decided to make rainbow cupcakes.

I love how these rainbow cupcakes turned out. The cake is moist and light – I used my favorite whipped cream cake recipe and used food coloring to create the colorful layers. These cupcakes are a little time consuming, but for a special occasion, they are worth the effort.

Ingredients for Rainbow Cupcakes

  • Cake flour
  • Baking powder
  • Salt
  • Heavy cream
  • Large eggs
  • Vanilla extract
  • Sugar
  • Food coloring

Cake flour is what gives these cupcakes a light and tender crumb. I have not tested this recipe with all-purpose flour and I don’t recommend using it because the cupcakes may not bake up as tender and light.

You can use whatever colors you like for the food coloring. For the cupcakes in the photos, I used purple, red, yellow, orange, and green. The yellow and orange blended together so I recommend switching the orange color for blue instead, which is what I have included in the recipe.

How to Make Rainbow Cupcakes

The cake batter is easy to make and most of the work is in creating the different colored layers for each cupcake.

Cake Batter

  • In a medium bowl, whisk the flour, baking powder, and salt.
  • In a stand mixer, whip the cream until stiff peaks form.
  • In another bowl, whisk the eggs and vanilla until combined.
  • On medium-high speed, slowly pour the egg mixture into the whipped cream. Slowly add the sugar. You should only need to mix for about 30 seconds to fully incorporate the sugar.
  • Add the flour to the whipped cream mixture and mix until combined and the batter is smooth.

How to Layer the Cupcakes

  • Divide the cake batter into five different bowls.
  • Add a few drops of each food coloring to each bowl and stir.
  • Line the cupcake pan with liners. Place a thin layer of each colored batter in the muffin cups, layering different batter each on top of the other.
  • Bake the cupcake for 15 to 17 minutes at 365°F. Cool the cupcakes fully before decorating.

Decorations for Rainbow Cupcakes

I kept the decoration very simple for my cupcakes and just piped some whipped cream frosting onto each. Here are some more ideas for decorating rainbow cupcakes:

  • Top them with vanilla buttercream frosting or chocolate buttercream frosting.
  • Make it really easy and use store-bought frosting to decorate your cupcakes.
  • Once you’ve frosted your cupcakes decorate them with colored sprinkles.
  • Or, if you’re like my family and hate frosting, just serve the cupcakes plain!

Making Cupcakes Ahead of Time

  • You make and bake these rainbow cupcakes up to a day in advance. I recommend cooling them completely and storing them in an airtight container. The next day, frost and decorate them before serving.
  • You can also freeze the cupcakes. Once cooled, store them in a freezer-safe and airtight container. They will keep in the freezer for up to three months. To thaw, just leave the cupcakes at room temperature then you can frost and decorate them.
