Method
 

  1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats.
  2. In a medium mixing bowl, whisk together the melted butter, eggs, and vanilla extract until well combined and slightly frothy.

  3. Add the entire box of fudgy brownie mix to the wet ingredients. Sprinkle in the baking powder.

  4. Using a spatula or wooden spoon, mix the ingredients until just combined and a thick dough forms. Be careful not to overmix; overmixing can lead to tough cookies.
  5. Gently fold in the chocolate chips and any other desired add-ins, such as chopped nuts or M&M's. Ensure they are evenly distributed throughout the dough.

  6. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. The dough will be quite thick, so you might find it easier to use a cookie scoop or two spoons.
  7. For a slightly flatter cookie with more of a crisp edge, you can gently press down on the top of each dough ball with your palm or the bottom of a glass.
  8. Bake for 10-12 minutes, or until the edges are set and the centers look slightly underbaked. The cookies will continue to set as they cool. For a gooier center, err on the side of less baking time.
  9. Let the cookies cool on the baking sheets for 5-10 minutes before carefully transferring them to a wire rack to cool completely.
  10. While the cookies are still warm, you can sprinkle them with a pinch of flaky sea salt for an extra layer of flavor complexity.

Notes

Store completely cooled cookies in an airtight container at room temperature for up to 3-4 days. For longer storage, freeze in a single layer on a baking sheet until firm, then transfer to a freezer-safe bag for up to 2-3 months. Reheat gently in a 300°F (150°C) oven for 5-7 minutes or microwave for a few seconds.
