These M&M brownies are so moist, so chewy, and loaded with M&Mโs! The mix of soft chocolate brownie and sweet M&M candies makes me feel all kinds of nostalgia. Plus, this recipe can fit into any holiday by swapping in seasonal M&M colors!

What makes these the BEST M&M brownies?
Texture texture texture! Iโm such a stickler for texture when it comes to brownies and when I created this recipe, I knew I wanted these brownies to be dense and chewy with loads of M&Mโs in each bite. Itโs safe to sayโฆmission accomplished.
These brownies are so chewy with that signature thin crackly crust on top. BUT some chewy brownies can lean cakey and these definitely do NOT! Theyโre so moist and so chocolatey thanks to a few secret ingredients.
And to make sure each bite has the perfect ratio of M&M to brownie, a mix of chocolate chips, regular M&Mโs and mini M&Mโs are folded into the batter. This mix allows the M&Mโs to really come through without overwhelming the brownies. Itโs just the right amount!


How to make chewy M&M brownies
The difference between chewy brownies and fudgy brownies narrows down to one major factor: fat.
Fudgy brownies have much more fat than chewy brownies, but itโs still important to have the right amounts and types of fats in chewy brownies in order to create a moist (not dry) brownie.
One of the key ingredients to creating chewy brownies is unsaturated fats, or vegetable oil. For this reason, this recipe calls for an even split of butter and oil. Butter still adds delicious flavor, while the oil creates that moist and chewy consistency.
The types of sugar also play a role in the chewy factor. Dark brown sugar is mixed in to the batter due to its rich molasses flavor. This added molasses lends a chewy texture that sugar alone cannot provide.
Last but not least, just a tiny bit of baking powder takes these brownies from dense and fudgy to light, moist, and chewy.

Tips for baking chewy brownies
- Flourย โ I say this in every post, and for good reason. Itโs the number one reason why most recipes fail. If thereโs too much flour, the brownies will turn out dry. If possible, measure the flour with a food scale. Otherwise, to ensure the exact amount, gently spoon the flour into the measuring cup and level it off with a flat edge. If scooped directly into the flour container, the flour becomes packed down into the cup which could leave you with 1/4 cup or more of added flour. Same goes for the cocoa powder!
- Butter โ When melting the butter, make sure to mix in the oil and cocoa right when itโs melted. Do not allow the butter to bubble on its own as this will release and evaporate its water content.
- Eggs & Sugar โ When whisking the eggs and sugar together, really get in there and whisk vigorously. Itโs important to break down the sugar granules to create a smooth brownie with a glossy surface.
- Mixing โ Once the dry ingredients are added, switch to a rubber spatula and gently fold the batter. Over working the batter can lead to a tough brownie, so take this last step slow and steady.
- Baking โ The brownies are done when a shell forms on the surface and the brownies are slightly puffed. If youโre unsure, itโs best to pull them when theyโre a bit underdone rather than over baked. Then, tap the pan on a hard surface when theyโre fresh from the oven. This will help create a closed chewy consistency.

M&M Brownies FAQs
You can, but stick with dark brown sugar for the best flavor and texture.
Use any mild flavored oil or, if you donโt mind the flavor, olive oil could also work great in these brownies.
Yes, feel free to sub more regular M&Mโs in place of the minis.
You can, I just prefer the more traditional flavor of regular cocoa powder paired with the sweet M&M candies.
Store the brownies in an air tight container at room temperature and theyโll keep tasting fresh for about 4-5 days.
I havenโt tried baking these in a 9ร13 dish, but if you decide to double the recipe thatโs the pan size I recommend. Try baking for about 10 extra minutes, or until the center becomes slightly puffed.
