Author: Donna Elick
Servings: 14 -16 cookies
Prep Time10 minutes
Cook Time8 minutes
Total Time18 minutes

Ingredients

Cookie Ingredients:

  • 1 box of dark chocolate brownie mix I used Pillsbury 18.4 ounce box
  • 2 tablespoons cocoa powder
  • 2 eggs
  • 1/4 cup unsalted butter melted
  • 1 tablespoon chocolate syrup
  • 1 teaspoon pure vanilla extract

Frosting Ingredients:

  • 2 cups powdered sugar
  • 1/2 cup cocoa powder
  • 1/4 cup water + extra if needed
  • 2 teaspoons pure vanilla extract
  • 1/3 cup multi colored sprinkles

Instructions

  • Line two baking sheets with parchment paper and preheat the oven to 375 degrees.
  • In a medium or large bowl, combine the brownie mix and cocoa powder.
  • Stir in the eggs, melted butter, chocolate syrup, and vanilla extract until mixed well - but don’t over mix.
  • Use a two tablespoon cookie scoop and create heaping cookie dough balls and place them at least 2” apart on the baking sheet - do NOT press down or flatten.
  • Bake for 8 minutes or until the edges are set. The center may still be a little soft.
  • Remove from the oven and let cool for at least 10 minutes on the baking sheet.
  • While one batch cools, bake the other 1-2 batches depending on the size of the baking sheet.
  • After the cookies are cooled, whisk together the frosting by combining the powdered sugar and cocoa powder.
  • Add the water and mix well.
  • Stir in the vanilla until smooth.
  • Spoon the frosting on top of each cookie and then sprinkle with the multi-colored sprinkles.
  • Let the frosting cool completely before storing.

Notes

I like to use a heaping 2 tablespoon scoop of cookie dough which will yield about 14 cookies. If your cookie dough balls are exactly 2 tablespoons the recipe will yield about 16 cookies.
The cookies can be made a day or two before and then add the frosting when you’re ready to serve.
Store the cookies in an airtight container at room temperature for up to 1 week or in the refrigerator.
Cookie dough balls can be frozen for up to 3 months before baking and adding the frosting.
