Ingredients

• 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
• 1½ cups powdered sugar
• 3 – 5 tablespoons milk
• 1 teaspoon peach or vanilla extract
• ¼ cup rainbow sprinkles

Instructions

1. Step 1: Preheat your oven to 350°F. Grease and flour a silicone or regular bundt pan. If using silicone, place the pan on a baking sheet for stability.
2. Step 2: In a mixer bowl, beat together the granulated sugar and softened butter. Stop once to scrape down the sides and bottom.
3. Step 3: Add eggs one at a time, beating on medium speed until the mixture is well blended.
4. Step 4: Reduce mixer speed to low, pour in the milk and vanilla or peach extract, then increase speed to medium and mix well.
5. Step 5: Add the flour, baking powder, and salt. Beat for about 1 minute or until smooth, stopping once to scrape the bowl.
6. Step 6: Divide the batter evenly into 4 bowls. Stir gel food coloring into each bowl—red, yellow, blue, and purple—until well combined.
7. Step 7: Pour the colored batters into the prepared pan in the order of red, yellow, blue, and purple layers.
8. Step 8: Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
9. Step 9: Cool the cake in the pan on a wire rack for 10-15 minutes. Carefully loosen and invert the cake onto the rack to cool completely.
10. Step 10: For the glaze, mix powdered sugar, 3 tablespoons milk, and peach or vanilla extract in a bowl until smooth. Add more milk if needed to achieve a pourable but thick consistency.
11. Step 11: Pour the glaze over the cooled cake and immediately sprinkle with rainbow sprinkles.
12. Step 12: Allow the glaze to set completely before slicing and serving.

Tips & Variations

• Use gel food coloring instead of liquid to avoid thinning the batter and to get brighter colors.
• For a dairy-free version, substitute whole milk with almond or oat milk and use dairy-free butter.
• Try adding a teaspoon of lemon zest to the batter for a fresh citrus twist.
• Use different flavor extracts like almond or coconut for a unique taste.

Storage

Store the Rainbow Bundt Cake covered at room temperature for up to 2 days. For longer storage, keep it in an airtight container in the refrigerator for up to 5 days. Before serving, allow the cake to come to room temperature for best texture. The glaze sets well and holds up during storage, but avoid prolonged exposure to humidity to keep it from softening.

How to Serve

Serve this delicious recipe with your favorite sides.

FAQs

Can I use liquid food coloring instead of gel?

You can use liquid food coloring, but it may thin the batter slightly and result in less vibrant colors. Gel food colors are recommended for the best visual effect.

Can I make this cake without a bundt pan?

Yes, you can bake the batter in round or loaf pans, but baking times may vary. Check doneness by inserting a toothpick and adjust baking time accordingly.

Ingredients

Scale 1x2x3x

Cake Batter

• 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

Glaze

• 1½ cups powdered sugar
• 3–5 tablespoons milk
• 1 teaspoon peach or vanilla extract
• ¼ cup rainbow sprinkles

Instructions

1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it’s ready when the batter is prepared.
2. Prepare the Bundt Pan: Grease and flour a silicone or regular bundt pan to prevent sticking. If using a silicone pan, place it on a baking sheet for stability.
3. Cream Butter and Sugar: In a mixer bowl, beat the softened butter and granulated sugar together until creamy, pausing once to scrape down the bowl to ensure even mixing.
4. Add Eggs: Incorporate the eggs one at a time, beating on medium speed until fully blended for a smooth batter.
5. Add Milk and Extract: Reduce mixer speed to low, add the whole milk and peach or vanilla extract, then increase the speed back to medium to combine thoroughly.
6. Mix Dry Ingredients: Add the all-purpose flour, baking powder, and salt to the wet mixture and beat for about 1 minute until smooth, scraping the bowl once to redistribute ingredients evenly.
7. Divide and Color Batter: Split the batter evenly into four bowls. Stir gel food coloring into each bowl—red, yellow, blue, and purple—until the batter is uniformly colored.
8. Layer Batter in Pan: Carefully add the colored batters into the prepared bundt pan in the order of red, yellow, blue, and purple to create the rainbow layers.
9. Bake the Cake: Place the pan in the oven and bake for 30-35 minutes. Check doneness by inserting a toothpick into the center; it should come out clean.
10. Cool the Cake: Let the cake cool in the pan on a wire rack for 10-15 minutes. Gently loosen it from the pan and invert onto a wire rack to cool completely before glazing.
11. Prepare the Glaze: In a medium bowl, mix powdered sugar, 3 tablespoons of milk, and peach or vanilla extract until smooth. Add more milk if needed to achieve a pourable yet thick consistency.
12. Glaze the Cake: Pour the glaze evenly over the cooled cake and immediately sprinkle with rainbow sprinkles for decoration.
13. Set and Serve: Allow the glaze to fully set before slicing and serving the cake.

Notes

• Ensure all ingredients, especially eggs and butter, are at room temperature for better mixing and texture.
• The silicone bundt pan is flexible and requires a baking sheet underneath to provide support while transferring to the oven.
• Adjust the amount of gel food coloring to achieve your desired color intensity for each layer.
• Allow the cake to cool completely before glazing to prevent the glaze from melting and running off.
• This cake can be stored covered at room temperature for up to 3 days or refrigerated for up to 5 days.
