Line a muffin tin with 12 muffin liners and spray with coconut oil cooking spray.
In a medium bowl, mix all ingredients for the bottom layer (chocolate) until smooth. Set aside.
In another medium bowl, mix all ingredients for the top layer (peanut butter) until smooth. Set aside.
Spoon a heaping 1/2 tablespoon of the chocolate layer into each muffin cup, then tap the tin to spread evenly.
Repeat with the peanut butter layer, adding a heaping 1/2 tablespoon on top of the chocolate layer. Tap the tin again to even out the cups.
Sprinkle each cup with Himalayan sea salt.
Freeze the muffin tin for 30 minutes or until firm. Enjoy!
Store the healthy peanut butter cups in the freezer for later enjoyment.
