Alternatively, combine coconut oil and chocolate and microwave in a microwave safe bowl in 30 second increments, until chocolate is fully melted. Stir in sweetner and pinch of sea salt.
Pour 2 tsp of melted chocolate into candy mold or paper lined muffin tin. Add 1 tsp nut butter on top, pressing down if needed. cover with 1-2 tsp melted chocolate, sprinkle with sea salt and garnishes of your choice and freeze until the chocolate is fully solid, about 1 hour.
To store, refrigerate in an airtight container in the fridge or freezer. Chocolate melts faster than regular candy at room temp.
*I got a low glycemic apple sweetener from Whole Foods. **I've used almond, peanut, and pistachio butter but like cashew butter the best
