Brownie Mix Cookies are the ultimate treat for when you need a quick, decadent fix. With just 10 minutes of prep and 9 minutes in the oven, you’ll have soft, fudgy cookies with crackly tops and rich chocolate flavor.

Packed with intense chocolatey goodness, each bite delivers a satisfying balance of sweetness and richness. The texture is pure perfection—crisp on the outside, gooey inside, and just the right amount of chew. Plus, they’re ready in under 20 minutes, making them the ideal dessert for busy days or last-minute cravings. You’ll love how easy and irresistible they are!
What You’ll Need
- 18.4 ounces brownie mix (use your favorite brand)
- ¼ cup all-purpose flour (helps thicken the dough)
- ¼ cup vegetable oil (or substitute with melted butter for richer flavor)
- 2 large eggs (room temperature works best)
- 1 cup mini M&M’s (or swap with chocolate chips, nuts, or other mix-ins)
How to Make Brownie Mix Cookies
- Preheat your oven to 375°F (190°C). Line a baking sheet with a silicone liner, parchment paper, or lightly coat with non-stick cooking spray.
- In a large mixing bowl, combine the brownie mix, flour, vegetable oil, and eggs. Stir until fully incorporated and a thick dough forms.
- Fold in the mini M&M’s (or your chosen mix-ins) gently to distribute them evenly throughout the dough.
- Using a cookie scoop or tablespoon, drop rounded spoonfuls of dough onto the prepared baking sheet, spacing them about 2 inches apart. Do not flatten—keep the dough in rounded balls for the best texture.
- Bake for 7-10 minutes. For chewy, fudgy cookies, aim for 7-9 minutes. For a firmer texture, bake closer to 10 minutes. The cookies will look slightly underbaked but will set as they cool.
- Remove the baking sheet from the oven and let the cookies cool on the sheet for 3-5 minutes. Then, transfer them to a wire rack to cool completely.
Fun Mix-In Ideas to Customize Your Cookies
While mini M&M’s are a classic choice, feel free to get creative with your mix-ins! Try swapping them for chocolate chips, chopped nuts, or even crushed pretzels for a sweet-and-salty twist. For a festive touch, use holiday-themed sprinkles or colored candies. The possibilities are endless, so make these cookies your own!
How to Store and Keep Cookies Fresh
Once cooled, store your Brownie Mix Cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the cookies in a single layer on a baking sheet, then transfer to a freezer-safe bag for up to 3 months. To enjoy, simply thaw at room temperature or pop them in the microwave for 10-15 seconds for a warm, gooey treat.
Perfect Pairings: Serving Suggestions
These cookies are delicious on their own, but they’re even better with a glass of cold milk or a scoop of vanilla ice cream for an indulgent dessert. For a fun twist, sandwich two cookies together with a layer of frosting or peanut butter. They’re also a great addition to dessert platters or holiday cookie exchanges!
Quick Tips for the Best Results
To ensure your cookies turn out perfectly, don’t overmix the dough—just combine until everything is incorporated. Also, resist the urge to flatten the dough balls before baking; they’ll spread naturally for that ideal chewy texture. If you prefer crispier cookies, bake them for the full 10 minutes, but for fudgy goodness, stick to 7-9 minutes.
Common Questions Answered
Can I use a different type of oil? Yes! Coconut oil or melted butter can replace vegetable oil for a richer flavor. What if I don’t have a cookie scoop? No problem—use a tablespoon to portion the dough, rolling it into balls by hand. And if you’re out of mini M&M’s, regular-sized ones or even chopped candy bars work just as well!
