If you haven’t noticed – unicorns are very popular right now. My neighbor makes cakes and she has 3 unicorn birthday cakes scheduled for 1 weekend. My daughter is 7 and or Christmas she asked for everything that had unicorns on them from pajamas, coloring books, t-shirts and more!

I know that this summer she will be asking for a unicorn party so I am doing some research now to prepare for her party. There are so many ways to add bright and fun unicorn colors to any party.

I love to make cookies with cake mixes. It cuts down on all the ingredients needed and they taste so good! Just recently I made some strawberry kiss cookies with a strawberry cake mix. So it was a fun time when my daughter and I found a white cake mix and lots of sprinkles in our pantry to make these unicorn cookies. They are just like a sandwich cookie or whoopie pie cookie with lots of color, lots of flavor and lots of fun.

Unicorn Cookie Cake Ingredients:

  • 1 white cake mix (only the cake mix – ignore the directions on the back)
  • ½ cup of butter (softened)
  • 1 3.4 oz package of vanilla pudding
  • 1 tablespoons milk
  • 1 egg
  • 2 oz bottle of sprinkles (about 1/3 cup)

Unicorn Vanilla Buttercream Icing:

  • 1 stick of butter softened
  • 2 ¾ cups powdered sugar 
  • 1 teaspoon vanilla 
  • 3-4  teaspoon milk 
  • Food coloring gel
  • 3 sandwich baggies

Instructions: For the Unicorn Cookies

Preheat oven to 350*. Line a cookie sheet with parchment paper and set aside.

In a large bowl, combine all the ingredients, except the sprinkles. (It’s best in a stand up mixer but you can also mix it by hand.) Once the batter is well combined, add the sprinkles.

Drop 1 inch balls onto the parchment paper. then press to flatten a little bit. Bake for 7 minutes. Do no over bake. Let cool for a minute and then transfer to a cooling rack. Let cool completely before you frost the cookies.

Instructions for the Unicorn Buttercream Icing:

With a mixer – mix the butter for about 2 minutes until it is light and fluffy. Add 1 cup of the powdered sugar, vanilla, and milk. Mix well. Slowly add the remaining powdered sugar. If it feels really stiff you can add a little more milk.


Divide the batter into 3 bowls. Add a few drops of the color to each bowl. I like the fluorescent gel color. But you can make them any color you want.

Put a sandwich baggie into a small narrow cup pushing the point into the bottom of the cup. Scoop the colored icing into the baggie. Seal the baggie at the top and then snip a small opening in the corner of the baggie. Push the frosting to the hole. (Repeat with the 3 colors.)

Grab a unicorn cookie and swirl the icing on the flat side of the cookie. Top with another unicorn cookie. Alternate the colors.

Serve and enjoy! Makes about 18 sandwich cookies.

Now for some more ideas that will help you host the most magical Unicorn Party Ever!

I have never used a cookie mix for this recipe. I don't think it would work because they have different dry mixes. You could try this recipe and then add the unicorn stuff - https://www.savingyoudinero.com/2019/01/10/white-chocolate-crinkle-cookies-with-a-chocolate-heart/
