Ingredients
  

  • 1 box 18-20 ounces brownie mix
  • Eggs oil, and water as called for on the box
  • 1 cup chocolate chips peanut butter chips, or chopped candy bars
  • 1/2 cup Nutella cookie butter, or peanut butter (optional)
  • 1/4 cup sprinkles crushed cookies, or chopped nuts (optional)

Method
 

  1. Preheat oven to the temperature specified on the brownie box and grease a 9x13-inch baking pan or line it with parchment paper.
  2. Prepare the brownie batter according to package directions, mixing the eggs, oil, and water with the brownie mix until well combined.
  3. Fold in your choice of mix-ins like chocolate chips, candy pieces, or nuts until evenly distributed throughout the batter.
  4. Pour the batter into the prepared pan and spread evenly.
  5. If using Nutella or peanut butter, drop spoonfuls on top of the batter and swirl gently with a knife to create a marbled pattern.
  6. Bake for 2-3 minutes less than the minimum time stated on the box, or until a toothpick inserted near the center comes out with a few moist crumbs.
  7. Allow brownies to cool in the pan for at least 15 minutes before cutting into squares and serving.
