Prep Time 10 minutes
Cook Time 35 minutes
Total Time 45 minutes
Servings 24 cookies


  • 1 box fudge brownie mix
  • 2 eggs
  • ¼ cup vegetable oil
  • 3 tablespoons all purpose flour
  • ¼ cup mini chocolate chips
  • 21 snack size Kit Kat bars {chopped}-reserve some for top


  1. Preheat oven to 350°.

  2. Combine brownie mix with eggs, vegetable oil and flour. Use a hand held mixer to combine the ingredients until you have a thick dough. Add in mini chocolate chips and ⅔ of the chopped Kit Kat bars. Stir in by hand until they are evenly distributed.

  3. Use a medium cookie scoop to scoop mounds of dough onto a silicone mat {or parchment} lined baking sheet.

  4. Bake for 9-11 minutes or until the edges are set, they will appear to be a little undercooked but that is alright. Remove from the oven and place 3-4 of the reserved chopped Kit Kat bars into the top of the cookie.

  5. Allow the cookies to cool on the cookie sheet for 10 minutes. Move to a cooling rack to cool completely. Store your cookies in an airtight container at room temperature for 4-5 days or freeze for up to 3 months.

Recipe Notes

  • If you want larger cookies, use a 1/4 cup measuring cup as a scoop and bake for 13-15 minutes.
