Step 1

Cook the popcorn in a WW 2-Piece Silicone Microwave Popcorn Popper as directed on the package. Or place the popcorn in a paper bag, or on a large piece of parchment paper. Fold over the edge of the bag to close, or fold edges of parchment to seal in popcorn. Microwave on High until the popping stops, 2 ½ to 3 minutes. Remove popcorn from microwave and uncover popper, or open bag or pouch to allow steam to escape.

Step 2

Place the popcorn in a medium bowl. Coat the popcorn with cooking spray, tossing to coat all pieces. Place the sugar and cocoa in a fine sieve or strainer and shake to dust the mixture over the popcorn; toss gently to coat. Stir in marshmallows and graham cracker pieces.
