You will also need 12 paper muffin cups. Melt half the chocolate in a sauce pan on the stove or in a bowl in the microwave. Place the muffin cups in a muffin pan (cut the cups in half to size for pb cups) and use a spoon the coat the bottom and sides of the cups with chocolate. Place in the refrigerator to harden (a few minutes) and mix the peanut butter, salt and sugar. The amount of salt and sugar needed may vary depending on the type of peanut butter. Soften the peanut butter mix in the microwave, fill the cups most of the way and return to the refrigerator for an hour to harden the peanut butter. Melt the remaining chocolate and top of the cups and refrigerate until hard. Enjoy!
