  • All-purpose flour
  • Granulated sugar
  • Baking powder
  • Salt
  • Unsalted butter
  • Eggs
  • Whole milk
  • Vanilla extract
  • Confectioners’ sugar
  • Heavy cream
  • Gel food coloring (various pastel shades)
  • White fondant
  • Edible gold dust or gold paint
  • Edible glitter (optional)
  • Black fondant or edible marker (for eyes)

Directions

  1. Bake the Cake: Preheat oven to 350°F (175°C). Grease and line three 6-inch or two 8-inch round pans. In a bowl, whisk together flour, baking powder, and salt. In a separate bowl, cream butter and sugar until fluffy. Add eggs one at a time, then mix in vanilla. Alternate adding dry ingredients and milk. Divide batter evenly and bake for 25–30 minutes or until a toothpick comes out clean. Cool completely.
  2. Make the Buttercream: Beat butter until creamy. Slowly add confectioners’ sugar, then heavy cream and vanilla. Beat until fluffy. Divide into bowls and tint each with different food coloring for the unicorn’s mane.
  3. Assemble the Cake: Level cake layers if needed. Spread a layer of plain or pastel buttercream between layers. Apply a crumb coat over the entire cake and chill for 15–20 minutes. Add a final smooth coat of white buttercream.
  4. Create the Decorations: Shape a unicorn horn by twisting fondant and securing it with a skewer. Paint with edible gold and let dry. Make ears from triangles of fondant and tint the centers pink. Use black fondant or edible marker to make closed eyes with lashes.
  5. Decorate: Insert the horn into the top of the cake. Position the ears on each side. Pipe buttercream swirls around the horn and down one side to create a colorful mane. Add glitter or sprinkles if desired.
