Line a baking sheet with parchment paper to prepare for the finished crackers.
Set aside 60 Ritz crackers. In a medium bowl, scoop out 1 cup of creamy peanut butter and stir until smooth if thick or chilled.
Spread a generous dollop of peanut butter onto half of the Ritz crackers using a small spoon or butter knife, aiming for an even layer.
Gently press a plain cracker on top of each peanut butter spread cracker to create sandwiches.
Pour 2 1/2 cups of chocolate chips into a microwave-safe bowl and microwave in 30-second intervals, stirring well after each, until melted and smooth.
If chocolate is too thick for dipping, stir in 1 to 2 tablespoons of butter, coconut oil, or shortening to thin and give a glossy finish.
Using tongs or a fork, dip each peanut butter sandwich into the melted chocolate, coating fully. Shake off excess chocolate.
Place coated crackers onto the parchment-lined baking sheet.
Refrigerate the baking sheet for at least 30 minutes until the chocolate hardens completely.
Remove from fridge and serve immediately or store for later enjoying these crunchy, creamy treats.
