In a bowl, microwave coconut oil, then add the peanut butter, sea salt and honey to the bowl and mix together. Using a muffin tin and muffin cups add in about a spoonful of the mixture (about 1/2 Tablespoon). Layer on top about a 1/2 Tablespoon of raspberry preserves. Layer about 1/2 tablespoon of the peanut butter mixture back on top. Top with sprinkles (optional). Stick in the freezer for about 20 minutes, pull out and enjoy!
