Bake this Rainbow Bundt Cake recipe if you’re looking for a really pretty bundt cake. Cake batter colored the colors of the rainbow are layered to make the most fabulous rainbow bundt.

This recipe comes from Beautiful Bundts: 100 Recipes for Delicious Cakes & More by Julie Anne Hession. I’m just going to start by saying that I really love this book! I enjoy baking a lot, and this book has so many great things to choose from.
The cakes in the book are fun and fabulous. There are basic bundt cakes, filled bundt cakes, layered and swirled bundt cakes, holiday bundt cakes, international bundt cakes and mini bundt cakes. My favorite, must-try, bookmarked recipes in these sections are the Vanilla Bean Bundt with Rum Butter Glaze, Lemon Lover’s Bundt, Boston Cream Bundt, Key Lime Bundt, Neapolitan Bundt, Strawberries & Cream Bundt, King Cake Bundt, Holiday Eggnog Bundt, Tres Leches Bundt, Chocolate Covered Stout Bundt, Lemon Poppy Seed Bundts and Pineapple Upside Down Bundts. There are so many more to be excited about, but these are just a few favorites.
The neat thing about this book is that there are coffee cakes and savory bundt recipes included too. I have my eye on the Glazed Cinnamon Raisin Roll Bundt, Savory Caprese Strata Brunch Bundt, Pepperoni Pizza Pull-Apart Bundt, Garlic Knot Pull-Apart Bundt, Retro Cranberry Mold Bundt, Hot Cross Bundt, Spaghetti Macaroni and Four Cheese Bundt, Layered Italian Turkey Meatloaf Bundt and Mushroom and Herb Stuffing Bundts. It’s crazy how many things can be made in a simple bundt pan, isn’t it?
How to make a Rainbow Bundt Cake:
This cake is made in a classic bundt cake pan. Make the batter, as directed in the recipe. Then divide the batter evenly among six bowls. Each bowl is colored with a few drops of food color. The batter is then scooped into the bundt pan, layer/color by layer. No swirling needed. The cake gets a swirly rainbow look all on its own while baking. A sweet lemon glaze is drizzled on top!
Rainbow Bundt Cake leftovers will be just fine for a couple of days. Just be sure to keep leftovers well-wrapped or in a covered bundt cake container. Keeping it at room temperature is just fine.
Julie Hession is an incredibly talented creator of cake recipes. This Beautiful Bundts cookbook is definitely one to add to your cookbook shelf if you love to bake cakes. I also have her Piece of Cake cookbook, and that one is my go-to book for all kinds of layer cakes.

Rainbow Bundt Cake
- 3 cups all purpose flour
- 2 teaspoons baking powder
- 1 teaspoon salt
- 1/2 teaspoon baking soda
- 2 1/4 cups granulated white sugar
- 1 cup (2 sticks) unsalted butter, at room temperature
- 1/4 cup vegetable oil
- 4 large eggs, at room temperature
- 1 tablespoon vanilla extract
- 1 1/3 cups buttermilk
- red, orange, yellow, green, blue and purple food coloring (gel paste works best- see notes below)
- 3 cups powdered sugar
- 1 teaspoon finely grated lemon zest
- 4 to 5 tablespoons freshly squeezed lemon juice
PREPARE THE CAKE:
- Preheat the oven to 350 degrees F. Spray a 12-cup bundt pan with nonstick spray.
- In a medium bowl, whisk together the flour, baking powder, salt and baking soda.
- In a separate larger bowl, use a hand mixer to combine the sugar, butter and oil on medium speed for 4 minutes, or until light and fluffy. Beat in the eggs, one at a time. Add the vanilla and beat for 2 more minutes.
- Alternately beat in the flour mixture and buttermilk, making three additions or flour and two of buttermilk, and beating until incorporated.
- Divide the batter equally among 6 small bowls, about 1 1/3 cups in each bowl. You can leave one portion in the mixing bowl. Stir in 4 to 8 drops red food coloring into one bowl and stir until thoroughly blended and the color is even (see Recipe Notes for color tips). Repeat with other food coloring and batters.
- Transfer the red batter to the prepared pan, spreading evenly using a spoon or an offset spatula., Repeat the process with the remaining batters in the following order: orange, yellow, green, blue and purple. Do your best to layer each color evenly without swirling into other colors (expect imperfections). The batter requires no swirling, since the batters will magically swirl on their own during the baking process.
- Bake for 55 to 65 minutes or until puffed and golden brown and a tester inserted in the center comes out clean. Let cool in pan for 10 minutes, then carefully invert the cake onto a wire rack to cool completely.
PREPARE THE GLAZE:
- In a medium bowl, whisk together the sugar, zest and 4 tablespoons juice until smooth. Whisk in more lemon juice if necessary (1 teaspoon at a time) until the glaze is thick, but pourable.
- Pour the glaze over the cooled cake, letting it drip down the sides. Let the glaze set for at least 15 minutes before serving.
- Gel color paste works best for this recipe. You can find it in the baking aisle of craft stores like Michaels. Plan to save it and use it for other recipes too- it's the only food coloring I use!
- Make-ahead tip: You can prepare this cake up to 3 days in advance. Store the cooled glazed cake in a cake container at room temperature or in the refrigerator.
