Spread 1 tablespoon of peanut butter onto a Ritz cracker. Sandwich another cracker on top and place on the baking sheet. Repeat with the remaining crackers.
In a small microwave safe bowl, melt the chocolate chips and the coconut oil in the microwave in 30 second intervals, mixing until smooth.
Dip the Ritz sandwiches into the melted chocolate, then return to the baking sheet. Repeat for the remaining sandwiches.
Place in the fridge until the chocolate is hardened.
