Why These Oreo M&M’s Cookies Work

● Uses common pantry staples you likely already have

Choosing the Right Ingredients for Oreo M&M’s Cookies

For the ultimate cookie texture, use all-purpose flour for structure and a combination of white and brown sugars. The brown sugar adds moisture and chewiness while white sugar creates those perfectly crisp edges.

Buying Tips

Look for regular-sized Oreos rather than Double Stuf for best cookie structure. For M&M’s, the standard size works better than minis as they maintain their shape and don’t melt completely during baking.

Substitutions

No Oreos on hand? Chocolate sandwich cookies work in a pinch. You can also substitute chocolate chips for M&M’s, though you’ll miss the colorful appeal and candy shell crunch.

Step-by-Step Oreo M&M’s Cookies Instructions

Pre-Cooking Prep for Oreo M&M’s Cookies

Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
In a medium bowl, whisk together flour, baking soda, and salt.
Place Oreo cookies in a ziplock bag and crush with a rolling pin into chunks (not powder).
Set aside about ¼ cup of M&M’s for topping the cookies.

Cooking Method for Oreo M&M’s Cookies

In a large bowl, cream together butter and both sugars until light and fluffy (about 3 minutes).
Beat in eggs one at a time, then stir in vanilla extract.
Gradually blend in the dry ingredients until just combined.
Fold in the crushed Oreos and M&M’s gently to avoid breaking the candies.
Scoop dough by rounded tablespoons (about 2 tablespoons per cookie) onto prepared baking sheets.
Press a few reserved M&M’s on top of each cookie dough ball.
Bake for 10-12 minutes until edges are golden but centers still appear slightly soft.

Doneness Check for Oreo M&M’s Cookies

Cookies should have golden edges but still look slightly underdone in the centers. They’ll continue cooking on the hot baking sheet after removal from the oven.

Resting Oreo M&M’s Cookies

Allow cookies to cool on baking sheets for 5 minutes before transferring to wire racks to cool completely. This resting period allows the cookies to set properly.

Pro Tips for Perfect Oreo M&M’s Cookies

Avoiding Dry or Flat Cookies

Don’t overmix the dough after adding flour – this develops gluten and creates tough cookies
Chill the dough for 30 minutes before baking for thicker cookies that spread less
Use room temperature eggs for better incorporation into the butter mixture

Tool Recommendations

Use a cookie scoop for uniform sizes and even baking
Silicone baking mats provide even heat distribution
Cool cookies completely on wire racks to prevent soggy bottoms

Storage & Freezing

Store baked cookies in an airtight container for up to 5 days
Freeze raw cookie dough balls for up to 3 months; bake directly from frozen (add 2 minutes to baking time)

FAQs About Oreo M&M’s Cookies

Can I make the dough ahead of time?

Yes! The dough can be refrigerated for up to 3 days before baking. Let it sit at room temperature for 15 minutes before scooping.

Why did my M&M’s crack in the oven?

This happens when the oven is too hot. Try reducing the temperature by 25°F and pressing some M&M’s on top of cookies immediately after baking.

How do I keep my cookies soft for days?

Store them with a slice of bread in the airtight container. The bread will release moisture to keep cookies fresh without making them soggy.
