These bars are simple, fun, and packed with flavors and colors that everyone will enjoy!
M&M’s scream of nostalgia, don’t they? Whether you used to pound handfuls of mini M&M’s at the movie theater or always looked forward to getting fun-size packets while going trick-or-treating, these little colorful gems were sure to put a smile on your face. And who can forget the feeling of diving into a McDonald’s McFlurry studded with all sorts of colorful, candy-coated treats? M&M’s are no ordinary chocolates—they transform the desserts that they are in, and these cookie bars are no different.
From the light, crispy, crunchy golden-brown edges to the gooey, melt-in-your-mouth inside, these bars contain everything you look for in the perfect cookie. The secret to this perfect balance lies in a couple of ingredients. First, the light brown sugar, which gives it its soft, melty texture. The second? The semisweet chocolate chips, which offer melty, chocolaty bites to balance the crunch of the colorful M&M’s.
How can I customize these M&M’s cookie bars?
A great thing about this dessert? It’s a classic. And while it stands strong on its own, it’s also easy to customize to fit personal taste. If you’re a Reese’s lover, for instance, feel free to swirl some peanut butter into the batter or, even better, replace the semisweet chocolate chips with peanut butter chips. Like a s’mores vibe? Throw in some mini marshmallows, which will get all ooey-gooey in the oven. And if you’re a fruit fanatic? Not to worry—just replace the M&M’s with chocolate-covered blueberries, and voilà: you’ve created a dessert just for you.
How do I store leftovers?
Just cut the bars into squares once cooled and store them in an airtight container at room temperature for up to 3 days. Longer than that? Keep them in the fridge—they’ll last in there for about 1 week. These bars also hold up in the freezer. Simply store them in a freezer bag or an airtight container, separating layers of bars with parchment paper, and store for up to 3 months. When ready to consume, defrost in the fridge overnight and bring to room temperature.
Serving suggestions
These bars would be even more delicious when topped off with a scoop of Chocolate-Pomegranate Ice Cream or, for a healthier alternative, some Cottage Cheese Ice Cream. You could also top them with a Chocolate Buttercream Frosting to make this a chocolate lover’s dream or spread on some Salted Caramel Peanut Butter Frosting for a true indulgence. The world’s your oyster!
Ingredients
- 2 3/4 cups all-purpose flour
- 3/4 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup unsalted butter softened
- 1 1/4 cups packed light brown sugar
- 1/4 cup granulated sugar
- 2 large eggs at room temperature
- 2 teaspoons vanilla extract
- 1 cup M&M's candies plus extra for topping, if desired
- 2/3 cup semisweet chocolate chips plus extra for topping, if desired
Instructions
- Preheat your oven to 350°F. Grease a 9×13-inch pan with nonstick spray and line it with parchment paper.
- In a medium bowl, whisk together flour, baking soda, baking powder, and salt.
- Separately, in a large bowl, beat softened butter, light brown sugar, and granulated sugar until smooth and creamy.
- Beat in large eggs and vanilla extract until well combined.
- Slowly add the dry ingredients to the wet mixture and mix just until combined. Do not overmix.
- Gently fold in M&M's candies and chocolate chips until evenly distributed.
- Spread the dough evenly into the prepared pan. Optionally, sprinkle extra M&M's and chocolate chips on top for a decorative touch.
- Bake for 22-27 minutes, until the edges are light golden and the center is set. Avoid overbaking to keep the bars chewy.
- Let the bars cool completely in the pan on a wire rack. Once cooled, use the parchment overhang to lift out and cut into squares.
- Serve your M&M's cookie bars with your favorite drink, like a cold glass of milk, and enjoy!
