How to Make Three Layer Peanut Butter Bars

  1. Preheat oven to 350°F (175°C).
  2. In a medium bowl, combine 1 ½ cups all-purpose flour, ¾ cup granulated sugar, 1 teaspoon baking powder, and ½ teaspoon baking soda.
  3. Cut in ½ cup margarine (1 stick) and 1 teaspoon vanilla extract until the mixture resembles coarse crumbs.
  4. Press the crumb mixture firmly into the bottom of an ungreased 13x9-inch baking pan.
  5. Bake for 15 minutes, or until lightly browned.
  6. Evenly distribute one 10-ounce bag of mini marshmallows over the baked crust.
  7. Bake for 2 more minutes, or until marshmallows begin to puff.
  8. Remove from oven and let cool completely.
  9. While the crust is baking, prepare the peanut butter layer: In a heavy saucepan over medium heat, combine one 14-ounce can of sweetened condensed milk and 1 cup creamy peanut butter.
  10. Cook and stir constantly until the mixture is slightly thickened, about 6-8 minutes. Be careful not to burn.
  11. Remove from heat and stir in ½ cup chow mein noodles, ½ cup chopped peanuts (or other nuts), and 2 teaspoons vanilla extract.
  12. Spread the peanut butter mixture evenly over the marshmallow layer.
  13. Let cool completely at room temperature.
  14. Refrigerate for at least 2 hours to allow the bars to set completely.
  15. Cut into bars and enjoy!
