Line a muffin tin with 12 muffin liners and then spray with coconut oil cooking spray and set aside.
In a medium bowl, stir all ingredients for the bottom layer (chocolate) together until smooth. Set aside.
In another medium bowl, stir all ingredients for the top layer (peanut butter) together until smooth. Set aside.
Scoop a heaping 1/2 tablespoon of the chocolate layer into each muffin cup. Repeat until you've filled 12 cups. Then, pick up the entire muffin tin and shake/tap it until the layer is set evenly.
Repeat the same thing with the peanut butter layer, adding around a heaping 1/2 tablespoon on top of the chocolate layer. Pick up the entire muffin tin one more time and shake/tap it until your cups are even.
Finally, sprinkle each cup with some Himalayan sea salt.
Place the muffin tin in the freezer for 30 minutes or until firm. Enjoy!
Store healthy peanut butter cups in the freezer to enjoy for later.
