Step-by-Step Guide to Making Unicorn Cake
Prepare the Cake Batter
- Preheat your oven to 350°F (175°C) and grease three 8-inch round cake pans. Line the bottoms with parchment paper for easy removal.
- In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- In a large mixing bowl, beat the softened butter and sugar with an electric mixer until light and fluffy (about 3-4 minutes).
- Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Mix just until smooth.
Add the Colors and Bake
- Divide the cake batter evenly into 4 or 5 bowls, depending on how many colors you want. Add a small amount of gel food coloring to each bowl and mix until the colors are vibrant.
- Pour each colored batter into the prepared pans, spreading evenly. You can either bake each color as a separate layer or swirl the colors together in one pan for a rainbow effect.
- Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Make the Buttercream Frosting
- In a large bowl, beat the softened butter until smooth and creamy.
- Gradually add the powdered sugar, one cup at a time, beating on low speed. Add the vanilla extract and heavy cream, adjusting the consistency as needed.
- Divide the frosting into separate bowls and add gel food coloring to create matching pastel shades for decorating.
Assemble the Cake
- Place the first cake layer on a cake stand and spread an even layer of frosting on top. Repeat with the remaining layers.
- Apply a thin crumb coat (a light layer of frosting) around the entire cake to seal in crumbs. Chill the cake for 15-30 minutes to set the crumb coat.
- Frost the cake with a smooth layer of white buttercream.
Decorate Your Unicorn Cake
- Using piping bags fitted with star tips, pipe colorful swirls of frosting on the top and sides of the cake to create the unicorn’s “mane.”
- Attach the fondant unicorn horn and ears to the top of the cake. If you’re using edible glitter, dust the horn and frosting for a magical sparkle.
- Pipe black buttercream or use edible markers to draw the unicorn’s eyes on the cake. Add sprinkles and pearl sugar for extra charm.
Serve and Enjoy
- Refrigerate the cake for 30 minutes to set the frosting. Slice and serve your magical unicorn cake, and enjoy the compliments from your guests!
