A couple of important notes on this one. 1) Rumor has it you can use just about any add-ins you can dream up, you'll just need to adjust the cooking time accordingly. I have never done this because you can't change perfection, but it's supposed to be one of those "clean out your pantry leftovers" type desserts, so feel free to go crazy. 2) This is probably the only time you will ever hear me say this, but when it says to let it cool in the pan for at least 30 minutes... let it cool in the pan for at least 30 minutes. I made these in a rush last night and didn't have time to wait for them to cool, so I made the foolhardy decision to just go ahead and cut and store them after a few minutes. Bad idea. As it turns out, baked goods consisting of primarily butter and sugar come fresh out of the oven as semi-molten globs worthy of consuming Anakin Skywalker's legs and his delusions of power. And then they smush when you try to put them in a container. You have been warned.
- 1/2 cup unsalted butter (1 stick), melted
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla
- 1 cup all-purpose flour
- 18 Oreos, coarsely chopped
- 1/2 cup M&M's
- Preheat oven to 350 F. Line an 8x8 baking pan with aluminum foil, spray with cooking spray, and set aside.
- In a large, microwave-safe bowl, melt the butter, about 1 minute on high.
- Allow butter to cool for about a minute so the egg doesn't scramble, then add egg, brown sugar, and vanilla. Whisk until smooth.
- Add in flour and stir until just combined. Don't over-mix!
- Stir in the Oreos, then turn batter out into the prepared pan and carefully smooth with a spatula.
- Evenly sprinkle M&M's over the top, then lightly press them into the batter so they don't fall off when you cut the bars.
- Bake for 20-22 minutes or until top is set and a toothpick inserted in the center comes out clean. Allow bars to cool in pan for at least 30 minutes before slicing and serving.
