UNICORN CAKE INGREDIENTS

This fun and easy Unicorn Cake recipe uses easy-to-find ingredients to create a delicious dessert your family will love.

All you need is:

UNICORN CAKE RECIPE INSTRUCTIONS

First, prepare the cake mix according to box instructions.

cake mix in small bowls

Separate the cake mix into four bowls. Add some gel colors to separate bowls of batter and stir to combine.

Food coloring in cake batter

Lightly grease the four cake pans. Pour the dyed batter into each prepared pan.

Bake the cake according to box instructions.

Cakes are done when you can stick a toothpick in it and it comes out clean.

Remove the cake from the oven and allow it to cool at room temperature until the cakes can be wrapped in plastic wrap in the freezer. 

While the cake layers are freezing make the buttercream frosting.

If you are in a rush chill the cakes in the fridge for at least two hours before attempting to assemble the cakes or else the cakes can come apart when you are icing them.

Once your cake layers are frozen, take each layer of cake and place buttercream frosting between the layers.

Next, frost the crumb coat the cake with a thin layer of buttercream.

Allow the cake time to rest before moving on to the next step.

American buttercream frosting will crust over, meaning when you touch it with your finger after about 15 minutes the Icing is no longer wet.

Using the white frosting, cover the cake in a final layer of frosting and use an icing smoother and smooth this layer of frosting.

Take the buttercream and now divide it into 3 bowls.

Add food gel dye to each bowl and whisk to combine.

Add each dyed buttercream to a piping bag with a star tip.

Remove the unicorn horn cake topper from its package and center it at the top of the cake.

After placing the unicorn horn topper on top of the cake, select your eyelashes and place them as symmetrical as possible. 

Use the star tip to create the roses on top of the cake.

Make roses using a star tip, by placing the center of the star tip where you want the rose to be.

Start making swirls with the buttercream. Then add colored frosting to the bottom of the cake in different colors.

Lastly, sprinkle with some unicorn sprinkles for a special added touch.

In about 4 hours, you’ll have a fun unicorn cake that’s sure to become a new favorite!
