- ½ c. butter, softened
- ¾ c. light brown sugar
- ¾ c. old-fashioned oats
- ½ c. flour
- ½ tsp. baking soda
- ½ tsp. salt
- ½ tsp. ground cinnamon
- 12 oz. semi-sweet chocolate chips
- ¾ c. graham cracker crumbs
- 1 ½ c. miniature marshmallows or large marshmallows cut into small pieces
Preheat the oven to 350° F. Generously spray a 9x13-inch baking pan with nonstick spray. Set aside.
Combine the butter, brown sugar, oats, flour, baking soda, salt, and ground cinnamon in a large bowl. Using an electric hand mixer, mix on LOW speed until all ingredients are combined, and dough is moist and crumbly.
Press the dough into a thin layer on the bottom of the prepared baking pan.
Sprinkle the chocolate chips evenly on top of the crust layer.
Bake for 20 minutes, until the crust is set and the chocolate chips are melted. Sprinkle the top of the melted chocolate evenly with the graham cracker crumbs. Then add the marshmallows and return to the oven for an additional 5 minutes or until the marshmallows are slightly browned.
Allow the pan to cool completely on a wire rack. Cut into bars, and store tightly covered at room temperature for up to one week.
