Line your cookie sheet with wax paper.
Spread just under a tablespoon of peanut butter onto the unsalted bottom side of a Ritz cracker, and then add another cracker on top (bottom side facing the peanut butter). You’re basically sandwiching the peanut butter between two crackers.
Lay all of your peanut butter-filled Ritz crackers out on the wax paper-lined baking sheet.
Melt your chocolate in a microwave-bowl bowl in the microwave. Heat in 15-20 second bursts at 50% power, and give it a good stir in between each interval until melted.*
Dip each peanut butter-filled Ritz cracker in the melted chocolate, using two forks or tongs.
Shake off excess chocolate before placing back on the wax paper-lined cookie sheet to set.
Leave your chocolate peanut butter Ritz cracker cookies to cool until the chocolate is set. This usually takes about 20 to 30 minutes at room temperature.
