What You’ll Gather
To create the most decadent M&M Brownie Cookies, you’ll need the following ingredients:
- 6 ounces unsweetened chocolate, chopped
- 1/2 cup butter
- 1 3/4 cups sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 1/4 cups all-purpose flour
- 1 1/2 cups M&M’s (plus more to garnish)
Before You Start: Equipment
Before diving into the baking process, gather these essential tools:
- Mixing bowls – for blending ingredients.
- Double boiler or microwave-safe bowl – for melting chocolate.
- Whisk or electric mixer – for mixing everything together.
- Baking sheet – to bake your cookies.
- Parchment paper – for easy cleanup and to prevent sticking.
- Cookie scoop or spoon – for portioning out dough.
Step-by-Step: M&M Brownie Cookies

Step 1: Melt the Chocolate and Butter
Begin by melting the unsweetened chocolate and butter together. You can do this using a double boiler on low heat or in a microwave, heating in short bursts and stirring in between until smooth. Allow it to cool slightly before using.
Step 2: Mix the Sugar and Eggs
In a large mixing bowl, combine the sugar and eggs. Use a whisk or electric mixer to beat them together until the mixture is light and fluffy. This step is crucial for achieving that perfect chewy texture.
Step 3: Add Vanilla and Chocolate Mixture
Once your chocolate and butter mixture has cooled slightly, stir in the vanilla extract. Then, gradually add the melted chocolate mixture to the sugar and egg mixture, stirring until well combined.
Step 4: Incorporate the Flour
Gently fold in the all-purpose flour until just combined. Be careful not to overmix, as this can lead to tough cookies.
Step 5: Fold in M&M’s
Now comes the fun part! Gently fold in 1 1/2 cups of M&M’s into the dough. This will add color and a delightful crunch to each cookie.
Step 6: Chill the Dough
Cover the mixing bowl with plastic wrap and refrigerate the dough for at least 30 minutes. Chilling helps the cookies maintain their shape while baking.
Step 7: Preheat the Oven
While the dough is chilling, preheat your oven to 350°F (175°C). Line your baking sheet with parchment paper to ensure easy removal of the cookies.
Step 8: Scoop and Bake
Once the dough is chilled, use a cookie scoop or spoon to drop rounded tablespoons of dough onto the prepared baking sheet, leaving enough space between each cookie. Press a few extra M&M’s on top for garnish. Bake for 10-12 minutes, or until the edges are set but the centers are still soft.
Step 9: Cool and Enjoy
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. Enjoy these delicious M&M Brownie Cookies warm, or store them for later!
Ingredient Flex Options

If you want to customize your M&M Brownie Cookies, consider these options:
- Swap unsweetened chocolate for dark chocolate for a richer flavor.
- Use coconut oil instead of butter for a dairy-free version.
- Try different types of candy-coated chocolates instead of M&M’s for a twist.
- Add nuts like walnuts or pecans for added crunch.
Notes from the Test Kitchen
- For extra fudginess, slightly underbake the cookies, as they will continue to cook on the baking sheet.
- These cookies are best enjoyed fresh but can be kept in an airtight container for up to a week.
- Feel free to experiment with other mix-ins, like chocolate chips or dried fruit.
Storage Pro Tips
To keep your M&M Brownie Cookies fresh and delicious:
- Store cookies in an airtight container at room temperature to maintain their softness.
- You can freeze the cookie dough for up to three months. Just scoop, freeze, then transfer to a baggie.
- For baked cookies, they can be frozen in a single layer and then transferred to a container for up to three months. Thaw before enjoying.
Quick Q&A
Can I use milk chocolate instead of unsweetened chocolate?
While you can use milk chocolate, it will alter the flavor and sweetness of the cookies. If you use milk chocolate, reduce the sugar slightly to balance the sweetness.
What should I do if my dough is too sticky?
If your dough is sticky, you can chill it longer in the refrigerator. Additionally, adding a bit more flour can help if the dough remains too soft.
How do I make these cookies gluten-free?
To make M&M Brownie Cookies gluten-free, simply substitute the all-purpose flour with a gluten-free flour blend. Make sure it’s a blend that works well in baking for the best results.
Can I make these cookies in advance for a party?
Absolutely! You can prepare the dough ahead of time and store it in the refrigerator or freeze it. Bake them fresh just before your event for the best taste!
