Three ingredients: Oreos, marshmallows, and butter. YUM.
It's pretty similar to Rice Krispie bars, but with Oreos instead. From looking around online, I found that people do different things with the Oreos. Some grind them to a fine powder, which makes the end result look like a chunk of asphalt. As for me, I like coarsely-crushed texture. You can still tell it's made with Oreos, which should be a badge of honor. It says, "I don't care about the calories. This sucker is gonna taste GOOD."
I found the recipe via Pinterest.com on Bakergirl's blog.
1 (16-ounce) package of Oreo cookies
5 cups (1 bag) of large marshmallows
4 tablespoons butter
Line an 8x8-inch baking dish with aluminum foil, allowing the foil to hang over the edges. Spray it with Pam or lightly butter it. (Because this recipe needed more butter.)
Crush your Oreos. Choose your method of violence. You can pulse them in a food processor or crush them in a large Ziplock bag, using a rolling pin. Crunch them into bits of your preferred size.
Get out a large microwave-safe bowl. Place the marshmallows and butter in the bowl and heat until the marshmallows get puffy, about 1.5 to 2 minutes. Pull out the bowl and add in your Oreos. Quickly stir, making sure it's mixed well. Pour the mix into the baking dish. Using a buttered big spoon or your hands, press the stuff down into the dish.
Allow it to set for 10 to 15 minutes. Use the foil edges to lift the contents from the dish, then cut, serve, and distribute the bars to friends so you don't eat them all yourself.
OM NOM NOM.
