If you’ve been hunting for the ultimate peanut butter fudge recipe, you’re in the right place. This creamy, dreamy treat is a nostalgic favorite that’s surprisingly easy to make at home. Whether you’re prepping for the holidays, gifting homemade goodies, or just craving something sweet and indulgent, peanut butter fudge is a no-fail choice.
Ingredients You’ll Need
To make this simple peanut butter fudge, gather these pantry staples:
- 1 cup unsalted butter (2 sticks)
- 1 cup creamy peanut butter (not natural)
- 1 teaspoon pure vanilla extract
- 1/4 teaspoon salt
- 3 1/2 to 4 cups powdered sugar (depending on your preferred firmness)
Tip: Avoid using natural peanut butter, as the oils can separate and affect the texture of your fudge.
How to Make Peanut Butter Fudge (Step-by-Step)
Step 1: Prepare Your Pan
Line an 8×8-inch baking dish with parchment paper or foil. Leave a bit of overhang so you can lift the fudge out easily later.
Step 2: Melt the Butter & Peanut Butter
In a medium saucepan, melt the butter and peanut butter over medium heat. Stir constantly until the mixture is smooth and fully combined. Do not let it boil.
Step 3: Add Vanilla & Salt
Remove the pan from heat and stir in the vanilla extract and salt.
Step 4: Mix in Powdered Sugar
Gradually mix in the powdered sugar, 1 cup at a time. You can do this by hand or with a hand mixer for a smoother finish. The mixture will become thick and stiff.
Bonus Tip: Sift your powdered sugar first to avoid lumps and ensure a silky texture.
Step 5: Press Into Pan
Press the fudge mixture into your prepared baking dish. Smooth the top with a spatula or the back of a spoon.
Step 6: Chill to Set
Refrigerate for at least 2 hours, or until firm. Once set, lift it out using the parchment paper and cut into squares.
Variations to Try
- Chocolate Peanut Butter Fudge: Layer melted chocolate on top before chilling.
- Crunchy Version: Use crunchy peanut butter or mix in chopped peanuts.
- Swirled Fudge: Swirl in a bit of marshmallow fluff for a fun twist.
- Sea Salt Finish: Sprinkle with flaky sea salt before refrigerating.
How to Store Peanut Butter Fudge
Store your fudge in an airtight container. It will keep:
- Up to 1 week at room temperature
- 2 to 3 weeks in the refrigerator
- Up to 3 months in the freezer (wrap tightly in plastic wrap and foil)
Let frozen fudge thaw in the fridge overnight before serving.
FAQs About Peanut Butter Fudge
Can I use natural peanut butter?
It’s best to use regular creamy peanut butter. Natural versions can make the fudge oily or grainy.
Why is my fudge crumbly?
Too much powdered sugar or overcooking can lead to dryness. Use the lower end of the sugar measurement for a softer texture.
Can I microwave the ingredients instead of using the stovetop?
Yes! Melt the butter and peanut butter in a microwave-safe bowl in 30-second intervals, stirring in between, until smooth.
