Pat mixture evenly onto bottom of 13 x 9-inch baking pan. Crust will be thin. Bake for 10 minutes; remove from oven. Pour sweetened condensed milk evenly over crust. Top with remaining ingredients except marshmallows; press down lightly. Bake for 18 minutes or until edges are light brown. Remove from oven. Sprinkle marshmallows on top of bars. Return to oven for 3 to 4 minutes or until marshmallows are puffy and edges of bars are golden brown. Cool completely; cut into bars. Makes 30 bars.
