Preheat oven to 350 F. Place half of the ritz crackers onto a baking sheet. Place one mini Reese's peanut butter cup onto each cracker.
Bake for 3-4 minutes. Remove from oven, sandwich each cracker with the remaining crackers.
Place chocolate chips into a microwave safe bowl, heat in the microwave in 30 second intervals, stirring after each until fully melted and smooth.
Dip each ritz cracker sandwich into the melted chocolate, set onto plates. Refrigerate until the chocolate has set.
