  1. Line a muffin tin with silicone liners.

  2. Melt the chocolate in either the crockpot or microwave.

  3. Add in melted coconut oil to melted chocolate and stir until well distributed.

  4. Using a small cookie scoop, place 1/2 tablespoon melted chocolate in each liner. Swirl the chocolate to cover the bottom of the muffin liner. Using a spoon, gently spread a 1/4″ of the chocolate up the sides of the muffin tin liner.

  5. Place muffin tin in fridge or freezer for 5 minutes for chocolate to harden.

  6. Once the bottom layer of the peanut butter cup has hardened, remove from fridge/freezer. Using a small cookie scoop, place 1/2 tablespoon peanut butter in each liner. Gently spread the peanut butter out over the chocolate base.

  7. Place 1-2 teaspoons of the remaining melted chocolate over the peanut butter layer. Use a spoon to spread evenly.

  8. Place the peanut butter cups back in the fridge/freezer for 5-10 minutes to harden.

  9. Remove from silcone liners and serve or store in the refrigerator for up to 4 days (if they last that long.)

Melting Chocolate in Slow Cooker

  1. Place chocolate in heat safe glass jar.

  2. Place jar in slow cooker and then carefully pour water into slow cooker until the water line reaches halfway up the jars. Be cautious not to get any water into the jar of chocolate.

  3. Turn slow cooker on high, do NOT put lid on the slow cooker, and in about 30 minutes your chocolate will be perfectly melted (no need to stir while chocolate melts). Check on chocolate after 20 minutes, as all slow cookers vary in temperature.
