How to Make Marshmallow Oreo Squares

  1. Preheat oven to 350°F (175°C). Grease a 9x9x2-inch baking dish.
  2. Coarsely chop 8 Oreo cookies. Set aside.
  3. Finely crush 26 Oreo cookies using a food processor or by placing them in a zip-top bag and crushing with a rolling pin.
  4. In a medium bowl, combine the crushed Oreos with 1/2 cup (1 stick) of melted margarine. Mix until evenly moistened.
  5. Press the Oreo mixture firmly into the bottom of the prepared baking dish to form the crust.
  6. Spread 10 ounces (approximately 1 1/2 cups) of marshmallow cream evenly over the crust, leaving a 1/2-inch border.
  7. Sprinkle 1/2 cup semi-sweet chocolate chips, 1/4 cup chopped nuts (your choice!), and the coarsely chopped 8 Oreos over the marshmallow layer. Press lightly.
  8. Bake for 18-20 minutes, or until the edges are lightly golden brown and the marshmallow is set.
  9. Let cool completely in the baking dish before cutting into squares. Refrigerate for at least 30 minutes for easier cutting and serving.
  10. **Lighter Version:** Use reduced-fat or sugar-free Oreo-type cookies, reduced-fat margarine, and 1/4 cup miniature chocolate chips.
