Ingredient Info and Substitution Suggestions
CAKE – Using 2 boxed cake mixes makes life a lot easier and requires less clean-up. You will also need the ingredients listed on the back of your cake mix boxes*. You can use a homemade white cake or vanilla cake recipe if you’d like, but you will likely have to double the recipe to fill a bundt cake pan. Gel food coloring will provide more vibrant colors as opposed to liquid. If you want brighter colors in your cake, slowly keep adding the food coloring until you reach the desired vibrancy.
GLAZE – Icing sugar (aka confectioners sugar or powdered sugar), milk, and vanilla extract. That’s it!
SPRINKLES – These unicorn sprinkles are pink, purple, and have little gold horns. Or you can opt for these more vibrant purple, pink, and white sprinkles!

- Preheat oven to 350 degrees F (175 degrees C). Grease a 9-10 inch bundt pan.
- Make cake batter as directed on the back of your box. Divide 3/4 (you probably won’t need all of it. You can use the last bit for cupcakes if you like) of the batter evenly into 4 or 5 bowls. Add food coloring to all but one bowl, leaving the last white.
- Pour batter into Bundt pan, one color at a time. Bake 50-60 minutes, until toothpick comes out clean in center. Cool 20-30 minutes before removing from pan. Allow to cool completely before adding glaze and sprinkles.
- Make glaze by adding icing sugar, vanilla, and 2 tablespoons of milk to a bowl. Beat slowly, adding more milk, a tablespoon at a time, until desired consistency is reached.
- Place cake on a cooling rack and then on a baking sheet. Pour glaze on cooled cake. Add sprinkles. Leave to set, approximately 30 minutes.
Frequently Asked Questions & Expert Tips
Yes, you can easily make this cake in a cupcake tin. Layer the colored batter into the tin as you would in a bundt cake pan. Follow the baking time on the back of your cake mix box for cupcakes.
You can either store this cake in an air-tight container or cake container at room temperature for up to 2 days or in the refrigerator for 4-5 days. It can be prepared a day in advance, any longer than that you risk losing moisture in the cake.
Serving Suggestions
Feel free to use a bit of food color in the glaze as well if that’s what you fancy, this bundt cake leaves so much room for creativity. Use different gel food color to match the theme of your party with sprinkles to coincide.
