Loaded M&M’s Oreo Cookie Bars
These cookie bars are stuffed with chunks of Oreos and M&Ms, perfect for parties or an easy dessert treat!
Ingredients
1/2 cup unsalted butter, melted
1 large egg
1 cup light brown sugar, packed
1 tablespoon vanilla extract
1 cup all-purpose flour
18 Oreo Cookies, coarsely chopped
About 1/2 cup M&M’s (plain or any flavor you like)
Instructions
Preheat & Prep Pan: Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with aluminum foil and spray with cooking spray.
Melt Butter: In a large, microwave-safe bowl, melt the butter (about 1 minute on high power).
Mix Wet Ingredients: Allow the melted butter to cool slightly, then add the egg, brown sugar, and vanilla. Whisk until smooth.
Add Dry Ingredients: Add the flour and gently stir until just combined. Avoid overmixing.
Add Mix-ins: Fold in the chopped Oreos.
Pour & Top with M&Ms: Spread the batter into the prepared pan, smoothing the top with a spatula. Evenly sprinkle M&Ms over the top, pressing them lightly into the batter.
Bake: Bake for 20-22 minutes, or until the edges are slightly firm and the top is set. A toothpick inserted in the center should come out with a few moist crumbs but no wet batter.
Cool & Serve: Allow the bars to cool in the pan for at least 30 minutes before slicing and serving. Enjoy!Prep Time: 5 minutes | Cook Time: 20 minutes | Cooling Time: 30 minutes | Total Time: 55 minutes
