Peanut Butter S'more Bars

1 tube refrigerated peanut butter cookie dough (can use homemade)

3 1/2 cups mini marshmallows

3/4 cup milk chocolate chips

2 tsp shortening

1 1/2 cups M&M's

~Let dough stand at room temperature for 5-10 minutes to soften.  Cut into 24 slices; arrange side by side in an ungreased 13"x9"x2" baking pan.  Pat together to close gaps.

~Bake at 350 for 18-20 minutes or until lightly browned and edges are firm.  Sprinkle with marshmallows; bake 2-3 minutes longer, or until marshmallows are puffy.

~In small microwave-safe bowl, melt chocolate chips and shortening; stir until smooth.  Sprinkle M&M's over marshmallow layer; drizzle with melted chocolate.  Chill until set before cutting.

Yield: 2 dozen

(I like to use different colors of M&M's, depending on the holiday or season)

Another note:  I think this would be absolutely delicious if instead of marshmallows you just covered the peanut butter bars (before cutting) with melted chocolate, let cool, and then sprinkled with M&M's.  Just an idea for the chocolate-lovers out there!
