Ingredients & Prep
Cake Prep Essentials
Ensure your unicorn cake has a smooth texture by preparing the cake layers properly.
- Trimming: Level the cakes once cooled to avoid uneven layers.
- Tenderizing: For added moisture, brush your cake layers with a simple syrup before frosting.
Buttercream Frosting & Color Mixing
- Buttercream Ingredients: Use unsalted butter, powdered sugar, and a splash of vanilla extract for the frosting.
- Coloring: Use gel food coloring to achieve vibrant colors for the unicorn’s mane and other decorations.
Pantry Staples
- Powdered sugar: For that perfect smooth frosting texture.
- Gel food coloring: This gives you rich, vibrant shades that won’t water down your frosting.
Step-by-Step Unicorn Cake Decorating Instructions

Pre-Cooking Prep
- Bake the cakes: Ensure the cakes are level and completely cooled before starting the decorating process.
- Prepare the frosting: Beat the buttercream to a light and fluffy consistency.
Decorating Method
- Apply the base coat: Begin by spreading a thin layer of buttercream across the cake for a smooth base.
- Create the unicorn mane: Use piping bags with different tips to create swirls, curls, and layered shapes in bright, pastel colors.
Final Touches
- Place the horn and ears: Make a fondant unicorn horn, and use additional fondant to form the ears. Attach these with a small dab of buttercream.
Resting
Let your cake sit for a few minutes to let the buttercream set and hold everything in place.
Pro Tips for Perfect Unicorn Cake Decorating
Avoiding Dry Buttercream
- Don’t overwhip the buttercream: Too much air can cause it to become dry and crack during decoration.
- Add more powdered sugar if too runny: This will help thicken your frosting and make it easier to work with.
Tool Recommendations
- Piping bags and tips: These are essential for creating the intricate mane details.
- Cake turntable: A turntable helps you smoothly rotate the cake while decorating.
Storage & Reheating
- Store the cake in an airtight container: Keep your unicorn cake fresh for up to 3 days.
- Freeze the cake: If you have leftovers, wrap them in plastic wrap and foil, then freeze for up to 2 months.
Flavor Variations
Spicy Twist
Add a touch of heat by mixing in some cinnamon or chili powder into your frosting for an unexpected yet delightful flavor combination.
Vegan Option
For a plant-based version, simply swap the dairy ingredients with alternatives like vegan butter and plant-based milk.
Global Flavors
- Tropical Unicorn Cake: Add pineapple or coconut to the frosting for a tropical twist.
- Matcha Unicorn Cake: Incorporate matcha powder into the frosting for a unique, earthy flavor.
Serving Suggestions
- Pair with sides: Serve your unicorn cake with fresh fruit or whipped cream for a balanced dessert plate.
- Wine Pairing: A sweet wine like Moscato pairs wonderfully with the sweetness of the cake.
