  • 2 ½ cups gluten free flour blend * see note
  • ¾ cup sugar
  • 2 teaspoons baking powder
  • teaspoon salt
  • 1 ⅓ cups strawberry puree
  • ½ cup butter melted
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon lemon juice
  • 2 eggs large
  • 1 cup almond milk or other dairy or non-dairy milk


  • 1 cup butter
  • 4 cups powdered sugar
  • 4-6 tablespoons water add 4 and then add the other two as needed

Ears and Horn Fondant:

  • 2 Peeps for ears - do not melt
  • 6 Peeps melted
  • 1 cup powdered sugar


For the Cake:

  • Preheat the oven to 350F degrees.
  • Add the dry ingredients to a bowl and whisk to blend.
  • In a mini food processor or blender, puree the strawberries.
  • In a medium sized bowl, add the wet ingredients and the strawberry puree and mix well.
  • Pour the wet ingredients into the dry ingredients and mix.
  • Spray the layer pans with coconut oil.
  • Pour the cake batter into the layer pans and bake for 18-20 minutes until done.
  • Allow the cake to cool while you make the frosting.


  • Add the frosting ingredients to a standing mixer.
  • Mix well until the frosting is creamy. (Start the speed low then slowly increase the speed.)
  • When the cake is cool, add a layer to a plate and frost the top, add the next layer and frost the top. Once all layers are frosted, frost the top and sides and use a frosting scraper to smooth.
  • Divide the remaining frosting into several bowls.
  • Add food coloring to each and stir.
  • Add frosting from each bowl to the bag, careful not to mix them.
  • Use the frosting bag to swirl circles on the top of the cake, going down the back. This is the "mane" section so include a little on the forehead area for the forelock.
  • Take two Peeps and cut them in half. These are the Unicorn's ears.
  • Grab the rest of the Peeps and add to a bowl. Melt the Peeps at 20 second intervals in the microwave, stirring between each interval.
  • When the Peeps are melted, add the powdered sugar gradually, a little at a time to mix it in. As the mixture thickens, it becomes like fondant. When the mixture is stiffer, shape it into a Unicorn horn.
  • Use food coloring or an edible marker to draw the eyes and mouth.


  1. I tested this recipe with Bob's Red Mill 1 to 1 GF flour blend. That doesn't mean other brands won't work, it just means I haven't tested other gluten free flour blends.
  2. Xanthan Gum - If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon.
  3. I used almond milk but other dairy-free kinds of milk will work but I do not recommend canned coconut milk.
  4. Using peeps and powdered sugar is a great way to make a homemade fondant for shaping the unicorn horn!
  5. This cake will keep for up to 3 days in an air-tight container or up to 4 months in the freezer.
