Evenly spread peanut butter onto half of the Ritz crackers. Sandwich with the remaining crackers.
Place the chocolate chips into a microwave-safe bowl, and heat in the microwave in 30-second intervals, stirring well after each interval until it is fully melted and smooth.
Using a fork, fully coat each Ritz cracker sandwich into the melted chocolate, set onto plates. Decorate with the sprinkles. Let sit until the chocolate has fully set.
