How to make Simple Unicorn Birthday Cake

Preheat oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.

In a medium-sized bowl, whisk together the flour, baking powder and salt. Set aside.

In a large mixing bowl, cream together the butter and sugar until light and fluffy.

Beat in the eggs, one at a time, followed by the vanilla extract.

Gradually add the dry ingredients to the butter mixture, alternating with the milk. Begin and end with the dry ingredients, mixing until just combined.

Divide batter equally into three bowls and tint each bowl with a different food coloring (pink, purple, and blue).

Pour colored batters into the prepared cake pans.

Bake for about 25-30 minutes, or until a toothpick inserted into the center comes out clean.

Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them onto wire racks to cool completely.

In a large mixing bowl, cream the softened butter until fluffy.

Gradually add the powdered sugar, milk, and vanilla, beating until smooth and well combined.

Divide the butter frosting into separate bowls and tint each bowl with the desired food coloring (pink, purple, and blue).

Place one cake layer on a serving plate. Spread a layer of the colored buttercream frosting on top.

Stack the second cake layer on top and repeat with the frosting. Finish by adding the final cake layer.

Use the remaining frosting to cover the sides and top of the cake, until it's evenly coated.

Decorate the cake with edible gold or silver stars, the unicorn horn, and ears. Sprinkle rainbow sprinkles on top for an extra touch of magic.

Allow the cake to chill for 30 minutes before serving.
