Prep & Cook Time
Prep Time: 10 minutes
Cook Time: 35 minutes (including scooping and baking in batches)
Total Time: 45 minutes
Servings: 24 cookies
Ingredients
- 1 box fudge brownie mix
- 2 large eggs
- ¼ cup all purpose flour
- ¼ cup vegetable oil
- ¼ cup semi-sweet chocolate chips
Instructions
- Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper or silicone baking mats.
- In a large mixing bowl, combine the entire box of brownie mix, flour, eggs, and vegetable oil. Stir until a thick, cohesive dough forms.
- Fold in the semi-sweet chocolate chips until evenly distributed.
- Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading. You can slightly flatten the tops with your fingers or the back of a spoon if desired.
- Bake for 10-12 minutes, or until the cookies are set around the edges but still look soft in the center. They will firm up as they cool.
- Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Extra Crackle: Roll tablespoon-sized dough balls in granulated or coarse sugar before placing them on the baking sheet.
- Peanut Butter Swirl: Add small dollops of peanut butter to the top of each dough mound and gently swirl with a knife before baking.
- Salted Caramel Finish: Immediately after baking, press a single soft caramel candy or a few flakes of sea salt onto the center of each hot cookie.
- Cookie Ice Cream Sandwich: Once completely cool, sandwich a scoop of vanilla ice cream between two cookies and press gently.
Tips for Success
- For uniformly sized cookies, use a small cookie scoop or a measuring tablespoon.
- The cookies will look underdone when you take them out; this is key for a fudgy center. They set up as they cool on the hot baking sheet.
- If your dough seems too sticky to handle, chill it in the refrigerator for 20-30 minutes before scooping.
Storage & Reheating
Store completely cooled cookies in an airtight container at room temperature for up to 4 days. For longer storage, freeze them in a single layer before transferring to a freezer bag for up to 3 months. To reheat, warm a cookie in the microwave for 10-15 seconds to restore its soft, just-baked texture.
FAQ
Can I use a different flavor of brownie mix?
Yes, but a “fudge” style mix gives the best dense, chewy texture. A “cake-like” style mix will yield a lighter, cakier cookie.
My dough is very sticky. Is that normal?
Yes, this is a thick, fudgy dough. Using a scoop or slightly wetting your hands can make portioning easier. Chilling the dough briefly can also help.
Why did my cookies spread too much or too little?
Over-spreading can happen if your brownie mix is older or if you omitted the flour. Little spreading may occur if you packed the dough too tightly or over-measured the flour. Ensure you are using a level ¼ cup of flour.
Can I make these cookies without the chocolate chips?
Absolutely. The cookies will still be delicious, just slightly less chocolate-forward. The chips add pockets of melted chocolate.
How do I get a shiny, crackly top on my cookies?
The combination of the brownie mix and eggs typically creates this effect naturally. Avoid over-mixing and be sure not to over-bake them.
Can I double this recipe?
Yes, you can easily double all the ingredients. You will just need to bake in more batches or use more baking sheets.
