Step 1

Preheat oven to 350°F.

Step 2

Place graham crackers into a large resealable plastic bag. Finely crush into crumbs. Combine graham cracker crumbs, powdered sugar and butter into a small bowl. Evenly divide crumb mixture into each cup of a 24 cup mini muffin pan. Press crumbs to form shallow cups. Bake 4-5 minutes or until edges are bubbling. Meanwhile, break two of the candy bars into rectangles. Remove pan from oven; place one rectangle into each cup.

Step 3

Cut marshmallows in half crosswise using scissors dipped in cold water. Place one marshmallow half, cut-side down, into each cup. Return to oven 1-2 minutes or until marshmallows are just slightly softened. Cool on a cooling rack for 15 minutes before carefully removing cups from pan. Cool completely on wire rack.

Step 4

Break remaining candy bars in small pieces and place in a small bowl. Microwave on high 1 minute-1 1/2 minutes or until melted and smooth, stirring every 20 seconds. Dip the top of each marshmallow into the melted chocolate. Turn top-side up and let stand until set.
