Essential Ingredients for Your Unicorn Bundt Cake
To embark on this delightful baking adventure, gather your ingredients first! You’ll find all precise measurements, a complete list of items, and detailed instructions in the printable recipe card located at the very end of this post. For now, let’s explore the key components that bring this magical cake to life.
Ingredient Spotlight & Smart Substitution Ideas
Let’s dive deeper into the ingredients and offer some helpful tips and alternative suggestions to ensure your Unicorn Bundt Cake turns out perfectly every time.
CAKE BASE – Our recipe calls for two boxes of white cake mix, typically 15 oz each, totaling 30 oz. This is a fantastic shortcut that streamlines the baking process, minimizes cleanup, and consistently produces a wonderfully light and fluffy cake. You will also need any additional wet ingredients specified on the back of your chosen cake mix boxes (usually eggs, oil, and water). While a boxed mix is recommended for ease and consistent results, if you prefer to bake from scratch, a homemade white cake or vanilla cake recipe can certainly be used. However, be prepared to likely double the homemade recipe to achieve enough batter to properly fill a standard 9-10 inch bundt cake pan. For creating those show-stopping, vibrant swirls, we highly recommend using gel food coloring over liquid food coloring. Gel colors are far more concentrated, delivering richer, more intense hues without thinning your batter. Start with a small amount and gradually add more until you reach your desired pastel vibrancy – a little goes a long way!
LUSCIOUS GLAZE – The elegant glaze requires just three simple ingredients: icing sugar (also known as confectioners’ sugar or powdered sugar), fresh milk, and a dash of vanilla extract. That’s it! This trio combines to create a smooth, pourable glaze that sets beautifully and adds the perfect touch of sweetness to complement the cake. For a dairy-free option, you can substitute regular milk with almond milk or oat milk, adjusting consistency as needed.
MAGICAL SPRINKLES – Sprinkles are where the true “unicorn” magic comes alive! The type of sprinkles you choose can completely transform the cake’s theme. For a classic unicorn look, we love these adorable unicorn sprinkles, which feature charming pink, purple, and little golden horn accents. If you’re aiming for even brighter, bolder colors, these vibrant purple, pink, and white sprinkles are a fantastic choice. Don’t hesitate to get creative! Gold edible glitter, edible pearls, or even a mix of star and heart sprinkles can add unique flair to your enchanting creation.
Step-by-Step Guide: How to Make Your Unicorn Bundt Cake
These step-by-step photos and detailed instructions are provided to help you visualize each stage of making this delightful recipe. For a convenient printable version, complete with precise measurements and full instructions, you can Jump to Recipe at the bottom of this post.
- Begin by preheating your oven to 350 degrees F (175 degrees C). This ensures the oven is at the correct temperature for even baking. While the oven preheats, generously grease a 9-10 inch bundt pan using baking spray or a combination of butter and flour. This crucial step prevents the cake from sticking and helps ensure a clean release.
- Next, prepare your cake batter according to the directions on the back of your boxed cake mixes. Once prepared, divide about three-quarters of the batter evenly into 4 or 5 separate bowls. You might not need all of the batter, and any leftover can be baked into delightful cupcakes! Add your chosen gel food coloring to all but one bowl, leaving the last bowl with plain white batter. Gently stir each color until it’s evenly distributed and you achieve your desired pastel vibrancy.
- Carefully pour the colored batters into the greased Bundt pan, one color at a time. You can layer them alternatingly or create small dollops of each color around the pan. Avoid overmixing once in the pan to maintain distinct color separation. Bake for approximately 50-60 minutes, or until a toothpick inserted into the center of the cake comes out clean. Once baked, let the cake cool in the pan for 20-30 minutes before gently inverting it onto a wire rack. It’s essential to allow the cake to cool completely before applying the glaze and sprinkles; otherwise, the glaze will melt and run.
- While your cake cools, prepare the simple vanilla glaze. In a medium bowl, combine the icing sugar, vanilla extract, and 2 tablespoons of milk. Begin beating slowly with a whisk or electric mixer. Gradually add more milk, one tablespoon at a time, until your glaze reaches a smooth, pourable consistency that is not too thin.
- Once the cake is fully cooled, place it on a wire cooling rack set over a baking sheet. The baking sheet will catch any excess glaze. Evenly pour the prepared vanilla glaze over the entire cooled cake, allowing it to drip down the sides for a beautiful finish. Immediately after glazing, generously add your colorful sprinkles before the glaze sets. Allow the glazed and sprinkled cake to set for approximately 30 minutes at room temperature before slicing and serving. This ensures the glaze hardens slightly and the sprinkles adhere well.
Frequently Asked Questions & Expert Tips for Success
Absolutely! This versatile recipe can easily be adapted for cupcakes. Simply layer the colored batter into a greased cupcake tin, just as you would with a bundt cake pan. Keep in mind that cupcake baking times are much shorter; refer to the baking instructions on the back of your cake mix box for the recommended cupcake baking duration to ensure they are cooked through but not overbaked. The colorful swirl effect looks just as magical in individual cupcake form!
To maintain optimal freshness and moisture, store your Unicorn Bundt Cake in an air-tight container or a specialized cake container at room temperature for up to 2 days. For extended freshness, you can also store it in the refrigerator for 4-5 days. If you plan to serve it at a party, it can be prepared a day in advance without compromising quality. However, we advise against making it much further in advance than that, as you risk the cake losing its delightful moisture and becoming dry.
For the most vibrant and true-to-life colors, gel food coloring is your best friend. Unlike liquid food coloring, gel colors are highly concentrated and won’t dilute your cake batter, which is essential for maintaining the cake’s texture. Start with just a tiny drop on a toothpick, mix it into your batter, and gradually add more if needed until you reach your desired intensity. Remember, the colors will look slightly lighter once baked, so don’t be afraid to go a touch bolder with the raw batter.
A clean release from a bundt pan is key to preserving its beautiful shape. First, use a good quality non-stick bundt pan. Second, grease it thoroughly! You can use baking spray with flour (our preferred method), or brush softened butter into every nook and cranny, then dust it lightly with flour, tapping out any excess. Make sure to get into all the ridges. After baking, allow the cake to cool in the pan for 15-20 minutes before attempting to invert it. This crucial cooling time allows the cake to firm up slightly, preventing it from breaking apart upon removal. If it sticks, gently tap the bottom and sides of the pan or carefully run a thin knife around the edges (if not fully non-stick).
Creative Serving Suggestions & Themed Variations
The beauty of this Unicorn Bundt Cake lies not only in its delightful taste but also in its incredible versatility for customization. Feel free to unleash your creativity! While a classic white vanilla glaze is elegant, consider adding a tiny drop of food coloring to the glaze itself to match a specific hue in your cake or to create an even more vibrant top layer. This bundt cake truly leaves so much room for imaginative variations and themed party creations.
Think beyond just unicorns! By simply switching up your gel food colors and sprinkles, you can transform this basic recipe into a cake for virtually any celebration. Imagine the delight of a dinosaur-themed bundt cake, featuring rich green, blue, red, and yellow cake layers, generously topped with these adorable dino sprinkles. Or, for a romantic touch, create a charming Valentine’s Day cake with soft baby pink and red layers, adorned with heart-shaped sprinkles. The possibilities are endless: patriotic red, white, and blue for national holidays, spooky orange and black for Halloween, or even ocean-inspired blues and greens for a mermaid or beach party. Let your imagination be your guide, and create a truly unique and memorable dessert for your next gathering!

Ingredients
- 30 oz white cake mix 2 15 oz cake mixes, prepared according to box directions
- gel food coloring in 3-4 different colors (for pastel hues)
Glaze
- 1 ¾ cup icing sugar aka confectioners sugar or powdered sugar
- 5 Tbsp milk up to 6 Tbsp as needed for desired consistency
- 1 tsp vanilla extract
- ¼ cup sprinkles unicorn or pastel-themed
Things You’ll Need
-
10 inch bundt cake pan
-
Mixing bowls
-
Wire cooling racks
Before You Begin
- When adding food coloring, start with just a small amount of gel food color to each bowl of batter. Gel colors are very potent, and a little bit goes a long way. Slowly add more until you achieve your desired level of pastel vibrancy.
- To keep your bundt cake fresh, store it in an air-tight container at room temperature for up to 2 days, or in the refrigerator for 4-5 days. Ensure it’s properly sealed to prevent drying out.
- It is absolutely crucial not to add the vanilla glaze to the cake until it has completely cooled off. If the cake is still warm, the glaze will melt, soak into the cake, and you won’t get that beautiful, set, glossy finish. Patience is key for perfect presentation!
Instructions
-
Preheat your oven to 350 degrees F (175 degrees C). Thoroughly grease a large 9-10 inch Bundt pan, ensuring all crevices are coated to prevent sticking.
-
Prepare the white cake batter according to the directions provided on the back of your boxed cake mixes. Divide approximately three-quarters of the prepared batter evenly into 4 or 5 separate mixing bowls. Add a few drops of gel food coloring to each bowl (except one, which will remain white) and gently stir until each color is uniformly blended and you reach your desired pastel shade.
-
Carefully pour the colored batters into the greased Bundt pan, alternating colors to create a beautiful swirled effect. Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for 20-30 minutes before gently removing it to a wire rack. Allow the cake to cool completely on the wire rack before proceeding to glaze and add sprinkles.
-
To make the vanilla glaze, combine the icing sugar, vanilla extract, and 2 tablespoons of milk in a bowl. Beat slowly, gradually adding more milk, one tablespoon at a time, until a smooth, pourable consistency is achieved.
-
Place the completely cooled cake on a cooling rack positioned over a baking sheet (to catch drips). Pour the prepared glaze evenly over the cake. Immediately scatter your colorful sprinkles over the wet glaze. Allow the cake to set at room temperature for approximately 30 minutes, or until the glaze has firmed up slightly.
Nutrition
The recipes on this blog are tested with a conventional gas oven and gas stovetop. It’s important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
