4-Ingredient Peanut Butter Fudge (naturally vegan with paleo option)

pure maple syrup (I don't recommend honey - see the post for reasons why!)

salted natural peanut butter (the kind with just salt and peanuts) or cashew butter for a paleo version

coconut oil1 (commenters have used unsalted butter for a dairy version with success!)

vanilla extract

roasted salted peanuts or cashews, coarsely chopped, optional – divided
