Ingredients You’ll Need

Gathering simple, everyday ingredients is all it takes to create these irresistible M&M Cookie Bars.

• Sugars: Both brown and granulated sugar balance sweetness and moisture perfectly.
• Eggs: Bind everything together while adding moisture for a soft crumb.
• Vanilla Extract: Adds warm, inviting aroma and depth of flavor.
• Flour: All-purpose flour creates structure and chewiness without heaviness.
• Baking Powder: Provides a subtle lift so the bars aren’t too dense.
• Salt: Enhances all flavors and balances sweetness in each bite.
• M&Ms: Adds that signature burst of colorful crunch and chocolatey sweetness.
• Chocolate Chips: Melty pockets of rich chocolate complement the candy perfectly.

How to Make M&M Cookie Bars

Step 1: Prepare Your Pan and Ingredients

Start by preheating your oven to 350°F (175°C) and greasing or lining a 9×13 inch baking pan with parchment paper. This will make removing the bars easier later. Then, gather all your ingredients so everything is ready to go.

Step 2: Mix the Wet Ingredients

In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until combined and slightly glossy. Then add the eggs and vanilla extract, stirring until smooth and creamy.

Step 3: Combine Dry Ingredients

In a separate bowl, sift together the flour, baking powder, and salt. Gradually add this mix into the wet ingredients, stirring just until no flour streaks remain. Avoid overmixing to keep the bars tender.

Step 4: Add M&Ms and Chocolate Chips

Fold in the star of the show — the M&Ms — plus the chocolate chips. Mix gently so candies don’t break apart but will be evenly distributed throughout the batter.

Step 5: Bake the Bars

Spread the batter evenly into your prepared baking pan. Bake for 22 to 25 minutes, or until the edges are golden and a toothpick inserted near the center comes out with a few moist crumbs. Let cool completely before slicing.

Pro Tips for Making M&M Cookie Bars

• Use Room Temperature Eggs: They blend more easily into the batter, helping create a smooth texture.
• Don’t Overmix: Stir just until combined to avoid tough bars.
• Cool Completely Before Cutting: Warm bars can crumble, so patience pays off.
• Quality M&Ms Matter: Choose your favorite flavor variety for the best taste experience.
• Line Your Pan: Use parchment paper for an easy clean-up and perfect bar removal.

How to Serve M&M Cookie Bars

Garnishes

For extra flair, sprinkle additional M&Ms on top right before baking or drizzle melted chocolate over the cooled bars to amp up the sweetness and presentation.

Side Dishes

These cookie bars shine alongside a cold glass of milk, a scoop of vanilla ice cream, or even a cup of hot coffee or tea for a cozy, satisfying combo.

Creative Ways to Present

Cut them into bite-sized squares for party platters, stack with layers of whipped cream and berries for a quick dessert trifle, or wrap individually for take-along snacks and gifts.

Make Ahead and Storage

Storing Leftovers

Keep your leftover M&M Cookie Bars in an airtight container at room temperature for up to 4 days to maintain freshness and chewiness.

Freezing

Freeze bars individually wrapped in plastic wrap and stored in a freezer bag for up to 3 months. Let thaw at room temperature before serving for best texture.

Reheating

Warm bars in the microwave for 10-15 seconds to bring back that fresh-baked softness and melty candy goodness.
