You sure can, and it’s easy to do, too! If you prefer fudgier cookies that are gooey like brownies, remove them before they’re completely set in the oven.
Any brand should do the trick just fine! While Betty Crocker is usually my tried and true go-to, you can use whatever box brownie mix brand you enjoy the most. If you already know you like the box mix, you know you’ll love the final product.
In an airtight container at room temperature, these cookies will stay nice and fresh for about 3 days.


Recipe Tips and Tricks
- Let the cookies cool first on the baking sheet before moving them to a wire cooling rack. That way, they don’t break apart when you try to move them.
- Use a cookie scoop to scoop the cookie dough onto the prepared baking sheet. When you use a cookie scoop, it ensures that all of the cookies are the exact same size, which helps them all bake evenly. Plus, they’re more ready for presentation that way too.
- If it’s the holiday season, switch up the regular M&M candies for more festive red and green ones! You can also use holiday-themed M&M’s for Valentine’s Day, Easter, and more.

These M&M brownie cookies are loaded with rich chocolate flavor and have the most irresistible gooey brownie-like texture. They’re also wonderfully quick and easy to whip up, which is perfect when you need homemade cookies baked in no time flat!

Very very disappointed. Batter was a powdered mess. Will not recommend this receipeagain. Followed instructions to the letter
I always recommend measuring your flour using the spoon-and-level method to make sure you’re not adding too much flour. If the flour is packed into the measuring cup, you can actually end up with up to 25% more flour than the recipe calls for, which could definitely lead to dry batter!
