Recipe Notes

  • *I personally like very dark chocolate and prefer it not to be very sweet, so I do not add any stevia.
  • Place the baking cups on a small sheet pan before filling them to make moving them around easier.
  • Cooling at room temperature takes a lot longer but produces a shinier treat. Cooling in the fridge may cause your chocolate to “bloom” or become a little cloudy, this does not affect the flavor.
  • Cocoa butter contains antioxidants and increases the melting temperature of the Peanut Butter Cups.
