How to Make M&M Cookie Bars

Step 1: Preheat and Prepare Pan

Start by preheating your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper or grease it lightly to make removing the bars easy once baked.

Step 2: Cream Butter and Sugar

In a large bowl, beat together softened butter and brown sugar until creamy and smooth. This step helps develop the chewy texture and rich flavor you want.

Step 3: Add Eggs and Vanilla

Mix in the eggs one at a time, followed by vanilla extract. Ensure everything is well combined for an even batter.

Step 4: Incorporate Dry Ingredients

In a separate bowl, whisk flour and baking soda, then gradually add to the wet mix. Stir until just combined to avoid overworking the dough.

Step 5: Fold in M&Ms

Gently fold in the colorful M&Ms to distribute them evenly throughout the dough without crushing the candies.

Step 6: Bake and Cool

Spread the batter evenly into the prepared pan and bake for about 25 to 30 minutes or until lightly golden and a toothpick comes out mostly clean with a few moist crumbs. Let cool completely before slicing into bars.

Pro Tips for Making M&M Cookie Bars

• Room Temperature Ingredients: Using butter and eggs at room temperature helps achieve a smooth and even batter.
• Don’t Overmix: Mix just until combined to keep the bars tender and chewy rather than dense.
• Even Spreading: Press the dough firmly and evenly into the pan for uniform thickness and consistent baking.
• Watch the Bake Time: To keep chewiness, avoid overbaking; pull the bars out as soon as edges are golden.
• Cool Completely: Allow the bars to cool fully before cutting to prevent crumbling and to let flavors set.

How to Serve M&M Cookie Bars

Garnishes

Sprinkle extra mini M&Ms on top just after baking for a colorful, eye-catching finish. Dusting with a light sprinkle of powdered sugar can add a touch of sweetness and elegance.

Side Dishes

Pair these bars with a glass of cold milk or a scoop of vanilla ice cream for a classic treat combo that’s always a crowd-pleaser.

Creative Ways to Present

Cut into bite-sized squares and arrange on a festive platter for parties. Wrap individual bars in wax paper or small treat bags to gift to friends or bring to potlucks.

Make Ahead and Storage

Storing Leftovers

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

Freezing

For longer storage, wrap bars tightly in plastic wrap and place in a freezer-safe container or zip-top bag. Freeze up to 3 months, then thaw at room temperature when ready to enjoy.

Reheating

Warm bars slightly in the microwave for 10 to 15 seconds to revive that freshly baked softness before serving, especially after refrigeration or freezing.

FAQs

Can I use peanut butter M&Ms in this recipe?

Absolutely! Peanut butter M&Ms can add an extra layer of flavor and texture that complements the chewy cookie base perfectly.

Are these M&M Cookie Bars gluten-free?

The standard recipe uses all-purpose flour, but you can substitute a gluten-free flour blend to make the bars gluten-free without compromising taste.

How do I keep the bars chewy instead of crunchy?

Be careful not to overbake and use brown sugar in the recipe, as it helps retain moisture and chewiness in the bars.

Can I substitute chocolate chips for M&Ms?

Yes! If you prefer a more classic cookie bar, chocolate chips are a great alternative and will still be delicious.

Make sure the bars are fully cooled, then use a sharp knife and cut gently with a rocking motion for clean edges.
