In a microwave safe bowl, microwave dark chocolate candy melts in 30 second intervals, stirring in between until smooth.
Using a spoon or small cookie scoop, drop a spoonful of chocolate into each cavity. Repeatedly tap the mold onto a hard flat surface to distribute chocolate in an even layer and remove air bubbles.
Refrigerate for 5-10 minutes to allow chocolate to set.
In a separate microwave safe bowl, microwave peanut butter melts in 30 second intervals, stirring in between until smooth.
Drop a spoonful of peanut butter on top of the chocolate layer and repeat process of tapping mold until candy surface is flat and air bubbles removed.
Refrigerate for an additional 5-10 minutes until candy is completely hardened. Carefully stretch sides of mold away from chocolate to remove.
Store in an airtight container at room temperature or package for gifting.
