Ingredients

The full printable recipe card with exact measurements and instructions is included below.

  • Box of brownie mix — any brand will work (example: an 8.3 oz box).
  • Salted butter — softened. You can substitute 1/2 cup vegetable oil if preferred.
  • Eggs — large eggs.
  • Vanilla instant pudding mix — use the dry powder (example: 3.4 oz box) to boost chewiness and moisture.
  • Room-temperature water — helps create a slightly crisp edge; substitute milk for a softer, chewier cookie.
  • Chocolate chips — or chocolate morsels for extra gooey texture.

How to Make Brownie Mix Cookies

  • Step One: Preheat the oven to 350°F. Line a baking sheet with parchment paper and set aside.
  • Step Two: In a large bowl, add the softened butter and half of the brownie mix. Beat with a mixer until combined.
  • Step Three: Add the eggs and water, mixing until incorporated.
  • Step Four: Stir in the remaining brownie mix and the vanilla instant pudding powder. The dough will be thick.
  • Step Five: Fold in the chocolate chips using a spatula.
  • Step Six: Use a medium cookie scoop to portion the dough into balls and place them on the prepared sheet. Leave about 1 1/2 inches between cookies to allow for spreading.
  • Step Seven: Bake for 11 to 12 minutes, or until the edges are set but the centers remain soft.
  • Step Eight: Let the cookies cool on the pan for 2 to 3 minutes, then transfer to a cooling rack to finish cooling.

Variations and Substitutions

  • Swap chips for milk, dark, or white chocolate, peanut butter chips, or a mix of chips.
  • Add 1/2 cup chopped walnuts or pecans for crunch.
  • Stir in 1 teaspoon brewed coffee to intensify the chocolate flavor.
  • Fold in 1/2 cup creamy peanut butter to create chocolate–peanut butter brownie cookies.

Storage Instructions

Store leftover cookies in an airtight container at room temperature for up to 3 days, or refrigerate for up to one week.

To freeze, let the cookies cool completely, then place them in a freezer-safe bag or container for up to three months. Thaw at room temperature before serving.

Do I Need to Chill the Cookie Dough?

No. This dough can be baked immediately after mixing—no chilling required.

Recipe Tips and Tricks

  • Use a cookie scoop for uniform cookies and even baking.
  • Space dough balls about 1 1/2 inches apart to prevent cookies from merging.
  • Let cookies rest on the baking sheet for a few minutes after removing from the oven; they finish setting as they cool and are easier to transfer.
  • Fold chocolate chips in with a spatula rather than mixing with the hand mixer to avoid overworking the dough.
