Instructions
Preheat oven to 375°F.
In a large bowl, combine the brownie mix, flour, oil, and eggs. Stir the ingredients together until the batter is thick. Add in the M&M’s, and stir in until they are evenly distributed throughout the batter.
18.4 ounces brownie mix, 1 cup all purpose flour, ¼ cup vegetable oil, 2 large eggs, 1 cup M&M's
Using a small portion scoop or a spoon, drop balls of dough that are about 1½ inches in diameter onto a baking sheet lined with parchment paper. Leave at least 1 inch in between the cookies.
Bake for 9-11 minutes, until the cookies are slightly firm on top.
If you want them to have more of a gooey brownie texture, remove them before they completely set in the oven, and allow them to slightly cool. The center should be soft like a brownie.
Notes
You can also use an 18-ounce or 18.3-ounce box of brownie mix.
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.
Storage: Store M&M brownie cookies in an airtight container at room temperature for up to 3 days, in the refrigerator for up to 5 days, or in the freezer for up to 1 month.
