Fudgy M&M Brownies
If you love my classic brownie recipe, you are going to love these. The addition of M&M’s not only adds a great flavor, but also makes them super colorful. For more treats with M&M’s, check out my famous M&M cookies, peanut butter M&M cookies or my fudgy chocolate M&M cookies.
One of our favorite Sunday traditions is to let the kids pick the dessert. They each get a turn helping me with the recipe and my 9 year old daughter made these M&M fudge brownies all by herself. She is becoming quite the baker.
The best thing about this recipe is that it only takes one bowl to make and less than 10 minutes to prep. They will be done in 30 minutes from start to finish! The end result is a super soft fudge brownie bursting with chocolate flavor. Serve with a scoop of vanilla ice cream and some hot fudge sauce for the ultimate dessert!
How to Make M&M Brownies
Make batter: Whisk together the butter, oil and sugars in a large bowl. Add the eggs and vanilla and whisk for another minute. Next stir in the flour, cocoa and salt until just barely combined. Fold in the chocolate chips and 1/2 cup M&M’s until smooth.
Bake in oven: Pour the batter in an 8×8″ baking pan lined with parchment paper. I let the parchment hang over the sides so I can easily lift them out once they’re done. Then add remaining 1/4 cup M&M’s on top. Bake at 350°F for about 20 to 25 minutes, or until a toothpick comes out clean.
Cool and cut: Remove from oven and let cool slightly in pan. Then use the parchment to lift the brownies out of the pan and transfer to a cooling rack. Once cooled, use a plastic knife to cut into 16 squares.
Variations
One of the best parts about this recipe is you can pretty much use any flavor that you’d like. There are so many different flavors and new varieties of M&M’s that come out throughout the year. I always love making these brownies with the holiday M&M’s. Here are some of my favorites below.
- The mini M&M’s work really well in the recipe and add lots of color throughout.
- You can use peanut M&M’s (although I do recommend chopping them in half, has they are larger).
- Peanut butter M&M’s and peanut butter chips are great for peanut butter lovers
- Caramel M&M’s are another option. You could even add in extra caramel chips.
- Add pretzel M&M’s with crushed pretzels if you love the sweet and salty combo.
- For extra crunch, add in 1/2 chopped nuts.
Freezer Tips
If you have leftovers, you can absolutely freeze the brownies to enjoy for later. Once they’ve cooled and are sliced into squares, simply wrap each individual brownie in plastic wrap. Then place the wrapped brownies in a freezer bag or container. They will keep in the freezer for up to 3 months. Let thaw on the counter for a few hours when ready to enjoy.

I love brownies! I also love M&M’s! This is the perfect dessert and I love it!
I agree – two of my favorites! So glad you loved them, Emmy :)
Excellent, fudgy, rich, and satisfying brownie! And it was easy to make! Doubled the recipe and baked for 40 minutes and it turned out perfect the way we like them. My family LOVED this recipe and it’ll be our go-to recipe for brownies!
Yay! So happy to hear the brownies were such a hit with your family :)
Excellent. Only problem I had was getting them off the paper. Even though I sprayed it.
So glad you enjoyed them :)
These Brownies were so easy to make and so delicious! My go-to recipe now.
Yay! So glad you loved them, Amy :)
Loved this recipe! I made it in an 8×8 pan for Valentine’s Day with pink and red M&Ms- it was fudgy and crispy on the edges. I recently doubled the recipe and put it in a 9×13 pan as indicated but it turned out cakey. Any tips on how to prevent that from happening because I really enjoyed this recipe the first time I made it!
So glad you enjoyed the recipe! They’re a little bit thicker in the 9×13″ pan. If you prefer them thinner, you could try using 3/4 of the batter and turn the remaining batter into mini brownie bites.
These brownies look absolutely fantastic. My kids will love it. Such a fun and delicious recipe. Now I can’t wait to start baking.
These were so fun to make with my kids! And they turned out perfect.
