Cover the Ritz cracker in peanut butter, place them on a cookie sheet and place them into the fridge. Melt the chocolate in a microwave safe bowl with a wide top.
Dip the peanut butter side of the cracker into the chocolate. Carefully lift out of the chocolate and place onto a cookie sheet lined with wax paper.
Once the chocolate is dry, store in an airtight container in the fridge.
Notes
For the peanut butter I suggest NOT using an "natural" spread where the oil separates from the peanut butter. You'll end up with ooze marks from the leaking oils and it could make the cracker soggy.[br]I store my finished cookies in the freezer and enjoy them frozen too!
