Tips to Make Surprise Unicorn Cupcakes

  • Because we made these surprise unicorn cupcakes kind of spur-of-the-moment, I made my own unicorn sprinkle mix, but if you’re not sure about making your own mix, which I totally get, you can just grab this adorable unicorn sprinkle mix here and save yourself the trouble.
  • Start with your favorite vanilla cupcake recipe. If you’re anything like me, you definitely need a “no-fail” cupcake in your life, so I always fall back on my Lazy Girl cupcakes. Done right every time–as long as you can follow a basic recipe.
  • If your heart is just set on it, you can make a cream cheese frosting, sure. But the best, most light and fluffy frosting you can pipe with a decorating bag is this awesome homemade buttercream in this recipe, with confectioners sugar and all the sprinkles you could ever dream of.
  • Always always always let your cupcakes cool to room temperature before you frost them because warm frosting is no fun. Particularly when you’re turning them upside down to dip them in sprinkles. You’re just asking for the frosting to just drop off on the counter then. LOL!
  • If you’re digging this idea, but you’re like “I’m not making cupcakes that need a pink top and a bunch of unicorn sprinkles! This is ridiculously girly!” you just first need to give me a pass because I have a kiddo that just loves all things unicorn like me. So, there’s that. But also, keep in mind that there are 9 million awesome options for filling surprise cupcakes that AREN’T unicorn sprinkles. Some of my favorite are:

I love how fun these unicorn surprise cupcakes turned out. They make for such a fun birthday cupcake or just a fun cupcake for a party!

Prep Time 10 minutes
Cook Time 25 minutes
Additional Time 10 minutes
Total Time 45 minutes



  1. Bake your cupcakes per the directions in the recipe and allow them cool completely before decorating.
  2. Using a cupcake corer or a large decorating tip, create a well in the center of each cupcake but DO NOT DISCARD THE CENTERS.
  3. Place 1 tablespoon of sprinkles (or other surprise) in the center of each cupcake, and then replace each cupcake center on top. 
  4. Cream together butter, sugar and milk until light and fluffy to make your buttercream frosting. If your buttercream is too thin, add powdered sugar 1 tbsp at a time. If it is too thick, add more milk, ½ tbsp at a time.
  5. Divide you frosting into two bowls.
  6. Add 3-4 drops pink food coloring to one bowl of frosting and stir until the color is pink throughout.
  7. Add 3-4 drops purple food coloring to the other frosting and stir until the color is purple throughout.
  8. Scoop your pink frosting into ONE SIDE of a piping bag with a round icing tip attached. Fill the other side of the piping bag with the purple frosting.
  9. Frost each cupcake in a big swirl and enjoy! photo collage tutorial of how to make unicorn surprise cupcakes unicorn party
