We went to Mackinac Island, Michigan not long ago, which is famous for its incredible and numerous fudge shops. I basically tried every flavor I could get my hands on while we were there because I love the stuff! It was consistently all really, really delicious fudge that had a wonderful texture to bite into, and then it just melted in your mouth. Peanut butter fudge was one of the flavors that surprised me. I’m not typically the biggest peanut butter lover unless there is also some kind of chocolate involved. but there was just something about the peanut butter fudge that was way better than expected! After trying many methods for making fudge, we all agreed that this old fashioned fudge recipe won our hearts. I tried methods that used marshmallow cream or sweetened condensed milk, but this easy fudge recipe was just the best. With its classic creamy texture and perfect balance of peanut butter flavor and sweetness, it is the best homemade fudge, and I know you’re going to love it too!

What You’ll Need
Scroll down to the recipe card below this post for ingredient quantities and full instructions.
Sugar – Two kinds are used in this peanut butter fudge recipe: light brown sugar and powdered sugar. Butter – Salted butter gives the best flavor and makes the best fudge. If you use unsalted butter, add an additional ¼ teaspoon salt to the mix. Milk – Whole milk works best for most recipes, but you could use something with a lower fat content (I have even used skim) and still have the fudge turn out well. Peanut Butter – For fudge, you want a creamy and smooth peanut butter like Jif or Skippy. Don’t use “natural peanut butter” because the oils tend to separate, and it won’t work as well. Vanilla Extract – For best results, use Homemade Vanilla Extract!
How to Make Peanut Butter Fudge
Prep: Line an 8×8-inch pan with parchment paper or an aluminum foil sling for easy removal and cutting once the fudge is set. If using aluminum foil, be sure to butter it so the fudge will come off more easily. Cook: Combine the brown sugar, milk, and butter in a medium saucepan over medium-high heat. Cook while stirring frequently until the brown sugar and butter dissolve and the mixture comes to a boil. Boil for 2 minutes. Mix: Remove from heat and stir in the peanut butter and vanilla until smooth and fully combined. Add the powdered sugar to a large, heat-safe bowl. Pour the hot peanut butter mixture over the sugar mixture. Beat them together with a hand mixer until fully combined, so that there are no lumps of powdered sugar remaining. Then transfer the fudge to the prepared pan. Set, slice, & serve: Let set at room temperature for about 3 hours until it is set up before slicing into squares and serving.
Substitutions and Variations
Crunchy Peanut Butter Fudge: Add chopped peanuts or sprinkle them on top for some extra crunch! I haven’t tested it this way, but I bet you could even use chunky peanut butter instead of creamy. Oreo Peanut Butter Fudge: Mix in 1 cup of coarsely chopped up Oreos for a peanut butter cookie crunch fudge! Chocolate Peanut Butter Fudge: Make a batch of peanut butter fudge, then a batch of my Creamy Chocolate Fudge, and layer it or swirl them together in the same pan! You would want to go with a 9×13″ pan if taking this approach. White Chocolate Peanut Butter Fudge: Make White Chocolate Fudge (just leave out the cranberries and pecans) and layer it or swirl it in with the peanut butter fudge. Peanut Butter & Jelly Fudge: This is next on my list to try, but I’m thinking you could use about ¾ to 1 cup of your favorite raspberry or strawberry jam and layer or swirl it with a batch of this peanut butter fudge. I would try making the fudge, then spreading half of it into a prepared pan and swirling it with half of the jam, then adding the remaining fudge and jam on top and swirling again to make sure it’s evenly mixed for both flavors in every piece.
