Unicorn Cupcakes
My unicorn cupcakes have a moist vanilla cake with fluffy vanilla buttercream. I used fondant ears, rainbow frosting, and an edible horn to make them look just like your favorite mystical creature.

Just like my mermaid cupcakes and my cookie monster cupcakes these unicorn cupcakes are perfect for birthday parties. They start with a box of doctored up cake mix with a few simple upgrades. They always a showstopper at parties and loved by kids and adults alike.
What Makes Our Recipes Unique: A Sprinkle of Food Science
- Bakery Style Cupcakes From a Box Mix: Swapping the water called for on the cake mix box with milk and the oil with butter gives us a super moist cake with a rich flavor.
- Swirled Frosting: Gel food coloring and a special technique help us get vibrant swirls from one bag.
- Premade Fondant and Horns: Store bought fondant is the perfect consistency and holds its shape well.
Ingredient Notes and Shopping Tips
- Butter: Butter makes the cake richer. Be sure to soften it first by leaving at room temperature for 45-60 minutes. Speed this up by cutting it into smaller pieces.
- Milk: Milk's fat and protein makes the cakes moist and tender.
- Eggs: Use room temperature eggs to help everything come together smoothly? Forgot to leave them set out? Place in a glass of warm water for a few minutes.
- Gel Food Coloring: I like gel over liquid as it gives you a brighter color without any excess liquid.
- Fondant: You can get this at craft stores like Michaels, or even at Walmart. Amazon has it too!
How To Make Unicorn Cupcakes

- Combine cake mix with butter, milk, eggs, and vanilla. Bake according to box directions.
- Roll out white and pink fondant, cut out circles, and pinch into ear shapes.
- Make buttercream by combining all ingredients and divide and dye each a different color.
- Pipe swirled frosting. Then top each with a horn and ears.
Krystle's Tips: Steal My Culinary School Secrets
- Don't Overfill Cupcake Papers: Fill only around two thirds of the way full. This prevents doming and gives you a flat surface for decorating.
- Use Powdered Sugar: Avoid using raw flour, instead dust your work area and fondant with powdered sugar to prevent sticking.
- Keep Covered: It dries out quickly which is great after decorations are made but not good when you're still trying to roll and shape it.
- Chill Frosting: I stick mine in the fridge for around 10-15 minutes. Chilling firms up the fat and helps keep the different colors stay separate.
- Practice Piping: Test a few stars on parchment paper to perfect your technique.
