Peanut Butter Cups are even better when they're homemade and topped with sea salt!
Melt 1 bag of the chocolate in a double boiler. (Or you could do this using a microwave, melting the chocolate for 30 second then additional 5 minute intervals until melted). Stir with a spoon or spatula until smooth. Remove the pan of melted chocolate from the stove and turn off the heat.
In a bowl, combine the peanut butter, crushed cookies or graham crackers, powdered sugar and 1/2 tsp salt. Stir with a spoon until well combined.
Meanwhile, remove the muffin pan from the refrigerator. Then divide peanut-butter mixture in tablespoonfuls or 1 inch balls into the chocolate cups.
You may use whatever sea salt you have on hand. If you have a gluten intolerance, feel free to use any crunchy gluten free butter cookie in the filling.
