How to Make Classic M&M Cookie Bars
-
Preheat your oven to 350°F (175°C) to ensure optimal baking conditions for your bars.
-
Prepare a 9×13 baking dish by lining it with foil, leaving some overhang on the sides. This makes for easy removal once your cookie bars are baked and cooled.
-
Spray the foil generously with nonstick cooking spray to prevent any sticky mishaps during the baking process.
-
Beat together the softened unsalted butter, granulated sugar, and golden brown sugar in a stand mixer until the mixture is light and fluffy, about 3-5 minutes.
-
Add in the eggs one at a time along with the pure vanilla extract, beating until well incorporated and smooth.
-
Mix the dry ingredients by lowering the mixer’s speed and adding the all-purpose flour, baking soda, and salt. Combine until no flour streaks remain.
-
Stir in the M&M’s and mini chocolate chips, being careful to reserve some for topping, ensuring every bite is packed with sweetness!
-
Transfer the cookie dough into your prepared baking dish and spread it evenly into the corners to ensure uniform cooking.
-
Press the reserved M&M’s and chocolate chips into the top of the cookie dough, making it all the more inviting and colorful.
-
Bake in the preheated oven for 30-35 minutes, or until the edges are light golden brown and the center is just set—perfectly chewy!
-
Cool completely in the dish before lifting it out using the foil overhang; then slice into squares and enjoy the delightful rewards of your efforts!
Optional: Drizzle with melted chocolate for an extra delicious touch!

Make Ahead Options
These Classic M&M Cookie Bars are perfect for meal prepping, allowing you to enjoy homemade goodness even on your busiest days! You can prepare the cookie dough up to 24 hours in advance by mixing all the ingredients as instructed and storing it in an airtight container in the refrigerator. To maintain their delightful texture, be sure to cover the dough tightly to prevent it from drying out. When you’re ready to bake, simply preheat your oven and transfer the chilled dough to your prepared baking dish, pressing it into the corners before adding the extra toppings. Baking from chilled will enhance the flavors and ensure they turn out just as delicious as if they were made fresh!
How to Store and Freeze Classic M&M Cookie Bars
Room Temperature: Store cookie bars in an airtight container at room temperature for up to 5 days to maintain their chewy texture and sweet flavors.
Fridge: If you prefer a firmer texture, you can refrigerate the bars for up to a week, just be sure to separate layers with parchment paper to avoid sticking.
Freezer: Freeze individual bars wrapped in plastic wrap and then in aluminum foil for up to 3 months; simply thaw at room temperature before enjoying.
Reheating: Reheat in the microwave for about 10-15 seconds to restore that fresh-baked warmth, enhancing the gooey chocolatey goodness of your Classic M&M Cookie Bars.
Tips for the Best Classic M&M Cookie Bars
- Soft Butter: Use room temperature butter for better creaming with sugar, ensuring a fluffy texture that’s vital for Classic M&M Cookie Bars.
- Measuring Flour: Spoon flour into the measuring cup instead of scooping it out to avoid compacting, which could lead to dense bars.
- Don’t Overmix: Once you add the flour, mix just until combined. Overmixing can toughen the bars, making them less tender.
- Even Spreading: When transferring the cookie dough to the baking dish, spread it evenly for uniform baking and a chewy end result.
- Cool Completely: Allow the bars to cool fully before cutting; this helps them set and makes slicing easier without crumbling.
- Storage: Keep leftover bars in an airtight container for up to five days to maintain freshness and softness.

Classic M&M Cookie Bars Recipe FAQs

What if my cookie bars come out too dry?
