Begin by preparing the Medjool dates. Cut a slit lengthwise down each date to create a pocket, ensuring you don't cut all the way through. Remove the pit.

Take a spoonful of peanut butter and fill each date pocket. Press in for a hearty bite. Sprinkle crushed peanuts over the peanut butter filling.

Melt the dark chocolate and optional coconut oil in a microwave-safe bowl for about 30-40 seconds. Stir until smooth.

Dunk each peanut-stuffed date into the melted chocolate, ensuring full coverage. Use a fork to help keep them intact.

Place the coated dates on parchment paper and refrigerate for about 15 minutes until the chocolate has set.
