Step-by-Step Guide to Creating the Best Unicorn Cake
Step 1: Bake the Cake Layers
The first step in making your cake is to prepare the cake layers. Each layer will be a different color to create the vibrant, rainbow effect that everyone loves. Here’s how to do it:
- Preheat the oven: Set your oven to 350°F (175°C) and grease and line four 8-inch cake pans.
- Mix dry ingredients: In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt. Set aside.
- Mix wet ingredients: In another bowl, beat the softened butter until it’s creamy. Add the eggs one at a time, mixing well after each addition. Then, add the vanilla extract and buttermilk, stirring until smooth.
- Combine dry and wet ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until fully incorporated.
- Color the batter: Divide the batter into four equal parts, and add different food colors to each portion (pink, purple, blue, and yellow).
- Bake the layers: Pour each colored batter into a separate cake pan. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Cool the cakes: Let the cakes cool in their pans for 10 minutes before transferring them to a wire rack to cool completely.
Once the cakes have cooled completely, they’re ready for the next step—frosting.
Step 2: Prepare the Buttercream Frosting
Now that your cake layers are ready, it’s time to make the frosting. Buttercream frosting is the perfect base for creating a smooth, colorful finish for your cake. Here’s how to make it:
- Beat the butter: In a large mixing bowl, beat the softened butter until light and fluffy.
- Add powdered sugar: Gradually add the powdered sugar to the butter, one cup at a time, beating until fully incorporated. Scrape down the sides of the bowl as needed.
- Add vanilla and cream: Add the vanilla extract and heavy cream to the butter mixture. Continue beating until the frosting is smooth and easy to spread.
- Color the frosting: Divide the frosting into four bowls, and add different food colors to match your cake layers (pink, purple, blue, and yellow).
Now you’re ready to start assembling and decorating your cake!
Step 3: Assemble and Frost the Cake
Here’s where the magic happens! Follow these steps to assemble and frost your cake:
- Layer the cake: Start by placing the first cake layer on your cake stand or plate. Spread a thin layer of frosting over the cake.
- Continue layering: Add the second cake layer, and repeat the frosting process. Continue layering the cakes, one on top of the other, until all the layers are stacked.
- Apply a crumb coat: Once all the layers are stacked, apply a thin layer of frosting over the entire cake to seal in any crumbs. This is called a crumb coat, and it helps to give your cake a smooth, even finish.
- Chill the cake: Place the cake in the fridge for about 15 minutes to set the crumb coat.
- Frost the cake: After chilling, apply a thicker layer of frosting over the entire cake. Smooth it out with a spatula to create a clean surface.
Step 4: Decorate with a Unicorn Cake Design
This is the fun part! Decorating your unicorn cake design is where you can get creative. Here’s how to add the finishing touches:
- Pipe the mane: Use the colored buttercream frosting and a star piping tip to pipe swirls of frosting around the top of the cake. Alternate the colors to create a vibrant, multi-colored unicorn mane.
- Add the horn and ears: Place your unicorn cake topper on top of the cake. If you don’t have a topper, you can create your own horn using fondant or edible glitter for an extra magical touch.
- Add finishing touches: Pipe additional swirls of frosting along the sides of the cake, or add edible glitter and sprinkles for a bit of sparkle.

Tips for Creating a Simple Unicorn Cake Design
If you’re looking for a simpler approach to decorating your unicorn cake, you can skip some of the more detailed piping and focus on the basic elements of the design. For example, try using a single color of frosting for the mane, or opt for a simpler unicorn cake topper without the added decorations. Even a minimalistic design can still have a magical impact.
