Step-By-Step Peanut Butter Fudge Recipe
- Prepare your pan: Line an 8-inch square baking dish with parchment paper, leaving excess paper on two sides for easy removal later.
- Boil base ingredients: Combine the unsalted butter, whole milk, granulated sugar, and light brown sugar in a large saucepan. Set over medium heat, stirring frequently as the butter melts and sugars dissolve. Once boiling, continue to stir and boil for 2 to 3 minutes to ensure full incorporation.
- Off heat, add flavor: Remove the pot from the heat. Immediately stir in smooth peanut butter, vanilla extract, and a pinch of salt. Mix vigorously until completely smooth and creamy, with no visible streaks.
- Transfer and set: Pour the hot fudge mixture into your prepared pan. Use a spatula to smooth the top.
- Chill: Allow the fudge to cool at room temperature for about 30 minutes, then transfer to the refrigerator. Chill for 2 hours, or until firm and set.
- Cut and serve: Once completely chilled, lift the fudge using the parchment handles, place on a cutting board, and slice into bite-sized squares.
Expert Tips for Foolproof Fudge
- Use smooth (not natural) peanut butter: Classic, shelf-stable peanut butter (such as Jif or Skippy) will yield the creamiest, most stable results. Natural peanut butter can separate and cause graininess.
- Avoid overboiling: Just 2–3 minutes is enough. Overcooking can make the fudge too firm or crumbly.
- Don’t skip the parchment paper: It makes removing and cutting the fudge clean and hassle-free.
- Quick mixing is key: Stir the peanut butter in immediately off heat to create a velvety, homogenous texture.
- Let it set fully before slicing: Chilling is crucial for the proper firmness and clean edges when cutting.
Serving Suggestions
- Holiday trays: Arrange on festive platters with other assorted sweets for parties and family gatherings.
- DIY gifts: Stack squares in cellophane bags or small boxes, tied with ribbon—ideal for holiday sharing or teacher gifts.
- Pair with coffee: Enjoy a square with your afternoon coffee or tea—a comforting pick-me-up treat.
- Peanut butter lovers’ dessert: Serve alongside peanut butter cookies or brownies for a themed dessert buffet.
Fun Variations
- Swirled fudge: Add dollops of melted chocolate, then swirl gently into the fudge before chilling for a chocolate-peanut butter marbled look.
- Crunchy add-ins: Stir in chopped salted peanuts, pretzel pieces, or toffee bits for extra texture and salty contrast.
- Mini marshmallow mix-in: Fold in a cup of mini marshmallows just before pouring into the pan for pockets of gooey sweetness.
- Chocolate-topped: Spread a thin layer of melted chocolate on top of the cooled fudge before chilling for a deluxe treat.
Storage and Make-Ahead Tips
- At room temperature: Store in an airtight container for up to 1 week in a cool, dry place.
- In the refrigerator: Stays fresh for up to 2 weeks—just allow fudge to come to room temperature briefly before serving for the best texture.
- Freezing: For longer storage, wrap squares tightly in plastic and then foil. Place in a freezer-safe bag and freeze up to 3 months. Thaw overnight in the fridge before enjoying.
Frequently Asked Questions
Q: Can I use crunchy peanut butter instead of smooth?
A: Yes! If you enjoy a little texture, substitute crunchy peanut butter or stir in chopped peanuts for added crunch. Just be mindful that very chunky varieties may make the fudge slightly less smooth.
Q: Do I need a candy thermometer for this fudge recipe?
A: No thermometer is needed. This recipe is designed to be low-stress and does not require precise temperature monitoring.
Q: My fudge turned out greasy or separated—what happened?
A: This can occur if you use natural peanut butter, which often has a higher oil content and less stabilizers. Using classic, shelf-stable peanut butter will prevent separation. Over-mixing or overboiling can also cause issues.
Q: Can I double the recipe?
A: Absolutely! Use a 9×13-inch pan and double all ingredients for a bigger batch. Cook times may increase only slightly.
Q: Is this fudge gluten-free?
A: All the core ingredients are naturally gluten-free, but always check your peanut butter and other items for any added gluten, especially if serving those with allergies.
