Rainbow Bundt Cake

This Rainbow Bundt Cake is so easy to make and such a fun project to bake with kids. It looks very festive and beautiful, no one will ever assume that it can be done in less than one hour. To have gorgeous and vibrant colors is key to use gel food colors. They are way more intense and look so pretty.

The cake itself is a classic vanilla-flavored bundt cake, that is tender and moist. It is finished with a sweet glaze and more colorful sprinkles. You can skip the glaze, as the colorful colors are enough to make this dessert stand-out.

Why You’ll Love this Recipe:

  • Festive and colorful, perfect for a special occasion or birthday party

Recipe Tips:

  • I prefer using a silicone bundt cake pan when baking bundt cakes. It just makes the removal process so much easier and it’s guaranteed that the cake won’t stick to the pan.
  • Using gel food color is key here, as it won’t add much extra liquid to the batter. A few drops will create gorgeous colors.
  • Be careful when you add another colored layer. Carefully level it out with the back of a spoon or spatula on top of the other level, without mixing it in.
  • If you will be using a silicone bundt cake pan consider that it heats up quicker than a regular pan, so check for doneness a few minutes earlier.

How to Freeze a Bundt Cake:

Wrap tightly in clear wrap and after that either add it to a freezer-safe bag or wrap in foil. Freeze for up to 3 months. When ready to enjoy, thaw in the fridge overnight.

Tools/Ingredients used to make this Recipe:

  • Gel Food Coloring – this set comes in a variety of colors and it won’t water down your recipe.
  • Silicone Bundt Cake Pan – I like how easy it is to bake using silicone pans, they are non-stick which helps a lot with cake removal.

Rainbow Bundt Cake

  • Prep Time20 MIN
  • Cook Time35 MIN
  • Servings 10 slices


  • 1 cup white granulated sugar
  • 1 stick 1/2 cup unsalted butter, softened
  • 2 eggs room temperature
  • 1 cup whole milk
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 2 teaspoons baking powder
  • ¼ teaspoon salt
  • 5-8 drops purple gel food color
  • 5-8 drops blue gel food color
  • 5-8 drops yellow gel food color
  • 5-8 drops red gel food color


  • cups powdered sugar
  • 3 - 5 tablespoons milk
  • 1 teaspoon peach or vanilla extract
  • 1/4 cup rainbow sprinkles


  • Preheat oven to 350°F.
  • Grease and flour a silicone or regular bundt pan. If using a silicone bundt cake, place it on top of a baking sheet pan.
  • In the bowl of a mixer, beat together granulated sugar and butter, stop once to scrape the sides and bottom of the bowl.
  • Add eggs one at a time and beat on medium speed until well blended.
  • Change speed to low and add milk and peach extract. Increase speed back to medium and mix well. Add flour, baking powder, and salt and beat about 1 minute or until smooth. Stop once to scrape the sides and bottom of the bowl.
  • Divide batter into 4 bowls and stir in gel food color with a spatula until well combined.
  • Add the colored batter into the prepared pan, start with red followed by yellow, blue and purple.
  • Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.
  • Let cake cool into the pan on a wire rack for 10-15 minutes. Gently loosen cake from pan and turn out onto wire rack; cool completely before icing.


  • Add powder sugar, 3 tablespoons milk and peach or vanilla extract into a medium bowl and mix until fully incorporated and smooth. If the glaze is not runny enough, add more milk. You need the glaze to be thick enough to hold it's "drip" on the cake, but runny enough to pour.
  • Pour glaze over the cake and immediately decorate with sprinkles.
  • Let the glaze completely settle. Slice and serve the cake.
