Ingredients
  

Base
  • 1 box Brownie mix - Any brand (Betty Crocker, Ghirardelli, etc.)
  • 2 large Eggs - Room temperature preferred
  • ¼ cup Vegetable oil or melted butter - Use butter for richer flavor
  • 2 tablespoon All-purpose flour - Helps cookies hold shape
Optional Mix-ins
  • 1 cup Chocolate chips or chunks - Adds double chocolate flavor
  • ½ cup Walnuts or pecans - Optional crunch
  • ½ cup M&Ms or candy pieces - Fun for kids
  • ¼ cup Peanut butter - Swirled in for variation
  • ½ cup White chocolate chips - For contrast
For Extra Fudgy Texture
  • 2 tablespoon Cocoa powder - Intensifies chocolate flavor
  • 1 teaspoon Vanilla extract - Rounds out flavor
  • 1 pinch Salt - Enhances sweetness

Equipment

  • 1 Large mixing bowl (For combining ingredients)
  • 1 Cookie scoop (For even-sized cookies)
  • 2 Baking sheets (Line with parchment)
  • 1 Parchment paper or silicone mats (Prevents sticking)
  • 1 Wire cooling rack (For proper cooling)

Method
 

  1. Preheat oven to 350°F (175°C). In a large bowl, combine brownie mix, eggs, oil, and flour until thick and glossy. Fold in any mix-ins.
  2. Line baking sheets with parchment. Scoop about 2 tablespoon of dough, roll into balls, and space 2 inches apart.
  3. Bake for 10–12 minutes until edges are set and centers appear slightly underbaked.
  4. Let cookies rest on baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
  5. Store in airtight container up to 7 days or freeze up to 3 months. Reheat before serving if desired.
