Ingredients for the Cake:

• 2 boxes of white cake mix
• 8 large egg whites
• 2 cups water
• 1 cup canola oil
• Yellow, pink and orange gel food coloring
• 3 9-inch round cake pans
• 1 10-inch round cake board

Ingredients for the Vanilla Frosting:

• 3 cups unsalted butter, softened
• 6 cups powdered sugar
• 5 tbsp heavy whipping cream
• 2 tsp vanilla extract
• Yellow, pink, orange, green gel food coloring
• 4 medium piping bag with star tip
• 1 small piping bag with a leaf tip
• 4 medium mixing bowls
• 1 package of Wilton floral icing transfers

To Decorate:

• Unicorn Horns and Ears and Eyes kit

Cake directions:

Preheat oven to 350 and spray cake pans with cooking/baking spray.

Add all cake ingredients to a large bowl (except for the food coloring) and use an electric mixer to beat until smooth.

Divide the cake batter into 3 bowls

Add 2-3 drops of yellow food coloring into one bowl and mix to get a pale yellow color.

Mix in 2-3 drops of pink food coloring into the second bowl and mix until thoroughly tinted.

Mix in 2-3 drops of orange food coloring into the second bowl and mix to get a pale orange color.

Pour each batter into their own cake pan

Place into the oven and back for 28-32 minutes or until a toothpick comes out clean.

Allow to cool completely on a wire rack.

Frosting directions:

Using a standing mixer, beat all ingredients (except for the gel food colors) until well-combined. You will want the frosting to be smooth but form stiff peaks.

Scoop 1 cup of frosting into each of the 5 medium bowls

Add a few drops of pink gel food coloring into one of the bowls. Mix and then scoop into a piping bag with a star tip.

Mix in a few drops of yellow gel food coloring into the second bowl, mix and scoop into a piping bag with star tip.

Mix in a few drops of orange gel food coloring into the second bowl with the 1 cup of frosting and scoop into a piping bag with star tip.

Mix in a few drops of green gel food coloring into the second bowl with the 1 cup of frosting and scoop into a piping bag with the leaf tip.

Scoop the remaining white frosting into the last piping bag with a star tip.

To Assemble the Cake:

Place one cake layer onto a cake board. Trim the dome off the top of the cake to make an even layer

Repeat the first step with other two layers.

Scoop 1 cup of white frosting onto the bottom layer and spread evenly.

Place the second cake layer on top and spread another cup of frosting on top.

Next, place the last layer of cake on top.

Use the remaining white frosting and frost entire cake.

Using the white, pink, yellow and orange piping bag (with star tip attachment), start piping the unicorn’s hair on the top and around one side of the cake to create a beautiful, colorful “mane.”

Place the horn, ears and eyes onto the cake.

Using the piping bag with the green frosting, randomly pipe petals into the flowers.

Place the icing transfers randomly into the hair.

Place into the fridge to harden the frosting – then serve and enjoy!
