If you are making the homemade chocolate, place the cocoa powder and coconut oil in a glass bowl. Heat for 1 minute in the microwave and stir. Mix in the agave.
Pour chocolate onto your parchment paper.
Add peanut butter to the chocolate and swirl it around using a knife or fork. Then top with peanuts and salted pretzels.
Place in the freezer until it hardens enough to break it into pieces.
