M and M brownies are my go-to dessert when I need something familiar but with a pop of fun. They have all the rich fudgy goodness of a classic brownie and a playful crunch from colorful M and Ms. This is the treat I whip up for birthdays and rainy days alike because they always disappear fast.
I made these for my daughter’s birthday party once and the plate was empty before we even finished singing Happy Birthday. Now friends ask for the recipe whenever I bring dessert.
Ingredients
- Butter: gives richness and moisture for that classic fudgy brownie bite Use real butter for best flavor
- Cocoa powder: brings chocolate depth Unsweetened cocoa is best so you control the sweetness
- Vanilla: rounds out the chocolate flavor Pure vanilla extract will make a difference
- Brown sugar: makes the brownies chewy and adds hints of caramel Light or dark both work but I love dark for extra depth
- Eggs: help with rise and create that tender crumb Use room temperature eggs for easy mixing
- All purpose flour: holds it all together Stick to the standard for best results
- Salt: balances the sweetness and boosts flavor Do not skip it
- M and Ms: provide color crunch and a little candy surprise Go for a fresh pack so the shells are crisp
Step-by-Step Instructions
- Preheat and Prep:
- Set your oven to three hundred fifty degrees Fahrenheit first so it reaches temperature. Line an eight by eight inch pan with parchment paper and leave a bit hanging over for easy lifting after baking
- Melt the Butter:
- In a large mixing bowl melt your butter until fully liquid but not bubbling. Stir often as it melts to avoid burning and let it cool for a minute before the next step
- Whisk in Cocoa and Vanilla:
- Add cocoa powder and vanilla to the melted butter Whisk slowly until perfectly smooth and glossy This step sets the chocolate flavor base for the brownies
- Mix in Brown Sugar and Eggs:
- Pour in the brown sugar followed by each egg one at a time Beat with a hand mixer or sturdy whisk until thick shiny and well blended This creates a silky batter
- Combine Dry Ingredients:
- Add in the all purpose flour and salt Gently mix until everything is just incorporated and no dry streaks remain Take care not to overmix at this stage
- Fill the Pan:
- Pour the blond batter into your lined pan Use a spatula to even out the top for an even bake
- Add M and Ms:
- Sprinkle M and Ms generously over the surface and lightly press them into the batter so they stay put during baking
- Bake:
- Place the pan in the center of your oven Bake for forty to forty five minutes You want a toothpick inserted to come out with a few moist crumbs not bone dry
- Cool and Slice:
- Let brownies cool in the pan for at least thirty minutes before lifting them out Slice into big chunky squares for the best eating experience

My favorite part is the crusty edge pieces with the candy coating melted just at the edges. My kids race to get the corner pieces every time I bake them. This recipe makes family movie night a little more special.
Storage Tips
Store leftovers in an airtight container at room temperature for up to three days. If you want to keep them longer pop brownies in the fridge where they will hold up for about a week. You can also freeze individual squares wrapped in plastic for easy grab and go treats later. I recommend warming them a few seconds in the microwave before serving to bring back the fudgy texture.
Ingredient Substitutions
You can swap almond or oat flour for all purpose if gluten is a concern Just be sure to use the right ratios as swapping flours can affect the texture. Mini chocolate chips or chopped nuts work in place of some or all of the M and Ms for a different twist. If you are low on brown sugar you can use half granulated sugar with a spoonful of molasses for a similar flavor.

Serving Suggestions
M and M brownies are great as they are but I love serving them warm with a scoop of vanilla ice cream and a drizzle of caramel or hot fudge sauce. For parties cut them in small squares and serve in mini cupcake liners. Sometimes I add a handful of M and Ms to the batter too so you get a little burst of color in every bite not just on top.
Cultural and Historical Context
Brownies have been a beloved American dessert since the early twentieth century and have spawned dozens of creative variations. This candy stuffed version is a playful nod to the way American bakers love adding whimsy to classic recipes making these brownies especially popular at kids' birthday parties and bake sales.
