    One Bowl Chocolate Brownie M&M Cookies

    October 19, 2021 by Jess Italiano 22 Comments

    Jump to Recipe

    One bite of these chocolate brownie M&M cookies and you will be hooked. They taste like the perfect fudgy brownie, and are jam packed with M&Ms and chocolate chips. I mean, what could be better?!

    Key Ingredients for Chocolate Brownie M&M Cookies

    • Unsalted butter for fat content and to allow the cookies to spread
    • Brown sugar for sweetness and moisture
    • Granulated sugar for even more sweetness
    • Egg to build structure
    • Vanilla extract for flavor
    • All-purpose flour to build structure
    • Cocoa powder to build structure and add the most amazing chocolatey flavor, of course!
    • Baking soda to help the cookies rise
    • Salt to enhance flavor
    • M&Ms and chocolate chips the perfect mix-ins!

    Yield

    This recipe makes about 15-17 large cookies!

    Method

    These one bowl cookies are soooooo easy to make, that's why I love them.

    First, melt your butter over the stove or in the microwave in 30 second increments, stirring every 30 seconds. Set aside for the melted butter to cool slightly.

    Then, in a medium sized bowl, whisk together the brown sugar and granulated sugar. Pour in the melted butter and whisk together until completely combined. Add the room temperature egg and vanilla extract and whisk until combined.

    Now we will add the dry ingredients right on top of the wet ingredients, so there is no need to dirty up anymore bowls! Add the flour, cocoa powder, baking soda and salt and fold together until a dough forms. Pour in your M&Ms and chocolate chips and fold together until evenly incorporated throughout the dough.

    Put a piece of tin foil or plastic wrap over the bowl (this will prevent the dough from drying out) and put the bowl in the refrigerator and leave to chill for about an hour. When the dough only has 10 minutes left to chill, preheat your oven to 350 degrees Fahrenheit and line a baking sheet with parchment paper.

    Measure out the cookies to be 60 grams (about 3 tablespoons) for large cookies, and place them on the baking sheet with 2-3 inches of space in between each cookie.

    Bake for 14-16 minutes or until the edges have set. Let cool for 5 minutes on the baking sheet, then transfer to a cooling rack to cool completely or enjoy all warm and melty!

          Hey there I was wondering, can I substitute the cocoa powder with dark chocolate?

          Hi Giulia! I haven't tried it, so I cannot guarantee the results. Sorry!

      I just came upon this recipe. Got a huge bag of Christmas M&Ms and wanted to make cookies. One of the best chocolate cookies I’ve ever had, and I’m 67 and never comment. Thanks for the great recipe and Happy Holidays.
