Loaded M&M's Oreo Cookie Bars
Description
The Loaded M&M's Oreo Cookie Bars start with a butter-melted base mixed with egg, brown sugar, and vanilla, then combined with flour until just incorporated. Adding chopped Oreo cookies makes the batter chunky and rich with chocolate cookie bits, and topping the batter with M&M's before baking adds a vibrant, crisp candy texture on the surface.
Baked in an 8x8 inch pan at 350°F, the bars develop edges that are firm and a center that is soft with a few moist crumbs, signifying doneness. Cooling the bars for at least 30 minutes before slicing helps them hold their shape. These bars deliver a mix of chewy cookie dough, crunchy candy, and rich chocolate sandwich cookie bits.
This recipe uses Oreo Chocolate Birthday Cake sandwich cookies, but other chocolate sandwich cookies or mix-ins like graham crackers or chocolate-covered pretzels could be substituted. The bars keep airtight at room temperature for up to a week and freeze well for up to six months, making them convenient for make-ahead treats.
Ingredients
- ½ cup butter 1 stick, melted, unsalted
- 1 egg large
- 1 cup light brown sugar packed
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 18 Oreo cookies coarsely chopped*
- M&M’s I used plain, use your favorite flavor or other chopped candy, about 1/2 cup
Instructions
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
- Add the flour and stir until just combined, don’t overmix.
- Stir in the Oreos.
- Turn batter out into prepared pan, smoothing the top lightly with a spatula.
- Evenly sprinkle the M&M's over the top, lightly pressing them down with your finger or a spatula.
- Bake for about 20 to 22 minutes, or until done based on add-ins used. Top should be set and edges slightly firm. A toothpick inserted in the center (if you can find a bare patch to test) should come out clean, or with a few moist crumbs, but no batter.
- Allow bars to cool in pan for at least 30 minutes before slicing and serving.
Notes
- Different types of chocolate sandwich cookies can be used or mixed with other chopped add-ins for variety.
- Bars store well in an airtight container at room temperature for up to one week.
- For longer storage, freeze bars in a sealed container for up to six months.
- Wait at least 30 minutes after baking before slicing to ensure bars hold together.
