Break graham crackers (rectangle size) in half, carefully until they are in squares.
Spread creamy peanut butter fairly thick on one half all the way to edges. Put another half graham cracker on top.
In a small microwave safe bowl, melt 1 1/2 cups of chocolate chips plus 2 Tablespoons of vegetable shortening in the microwave. Cook on high for 30 seconds. Stir well. If not all the way melted and smooth, put it back in the microwave for 30 seconds. Remove. Stir well. By now the chocolate and shortening should be completely melted. If not, put it back in for only 10 seconds. Stir until smooth. (Do not overcook or it will BURN)
Place chocolate coated grahams onto aluminum foil and do not move them until chocolate has completely hardened (in about 1/2 hour or so). If you're desperate, you can put them in the refrigerator to speed the firming up process along. Once chocolate has hardened, remove from foil and serve. Store extras, covered, in the refrigerator to keep the chocolate firm.
As written, this recipe made a total of 8 chocolate covered grahams, but obviously, you can adapt this to make any quantity you desire.
