If you are a peanut butter lover, you are going to FLIP over this 4 Ingredient Peanut Butter Fudge! Made with healthier ingredients but just as creamy, rich and decedent as traditional.
Transfer the peanut butter mixture into the prepared pan and smooth the top of the fudge mixture out as best as you can with the back of a spatula or wooden spoon.
Add to the freezer for 10 minutes to firm up slightly then sprinkle the chopped Reese cups on top (if you are using). Freeze for 30 minutes to an hour or until firm.
