Peanut butter fudge is the perfect treat when you’re craving something rich, creamy, and indulgent but don’t want to turn on the oven. This no-bake recipe is incredibly easy to make, requires just a few ingredients, and comes together in minutes. With its smooth, melt-in-your-mouth texture and intense peanut butter flavor, it’s a guaranteed crowd-pleaser for both kids and adults.
This particular recipe uses a simple combination of butter, smooth peanut butter, vanilla extract, and powdered sugar to create a classic fudge consistency without the need for boiling sugar or candy thermometers. It’s ideal for beginners, quick desserts, last-minute gifts, or make-ahead treats.
The magic lies in how the ingredients blend. When the butter and peanut butter are melted together, they form a silky base that binds the powdered sugar into a thick, fudge-like mixture. Once chilled, the mixture firms up into sliceable squares that hold their shape and stay soft and creamy on the inside.
Ingredients
- 1 cup (240 ml) unsalted butter
- 1 cup (250 g) smooth peanut butter
- 1 teaspoon vanilla extract
- 3½ cups (420 g) powdered sugar
You don’t need anything fancy here. The butter provides richness and structure, while the peanut butter adds body and flavor. Vanilla brings a subtle depth and sweetness, and powdered sugar thickens the mixture and gives it the smooth, velvety texture that makes fudge so irresistible.
Step-by-Step Instructions
- Prepare the dish: Line an 8×8 inch (20×20 cm) square dish with parchment paper, leaving some overhang on the sides to help lift the fudge out once it’s set. This step makes removal easy and keeps cleanup simple.
- Melt the butter and peanut butter: In a medium saucepan set over medium heat, combine the butter and peanut butter. Stir frequently as they melt together, ensuring a smooth and even texture. This usually takes about 2 to 3 minutes. Don’t let the mixture boil or brown—you’re just melting, not cooking.
- Remove from heat and add vanilla: Once fully melted and smooth, remove the pan from the heat. Immediately stir in the vanilla extract. This adds aroma and rounds out the flavor.
- Incorporate powdered sugar: Gradually add the powdered sugar to the warm peanut butter mixture. Stir continuously with a wooden spoon or rubber spatula until the sugar is fully incorporated. The mixture will quickly thicken into a dense, fudge-like consistency. It should be smooth but firm enough to hold its shape.
- Transfer to the prepared dish: Spoon the fudge mixture into the lined dish. Use a spatula to press it down evenly and smooth the surface. Work quickly, as the fudge will begin to set as it cools.
- Chill: Place the dish in the refrigerator for at least 2 hours, or until the fudge is completely firm. You can also chill it overnight for convenience.
- Cut and serve: Once chilled and set, lift the fudge out of the dish using the parchment paper. Place it on a cutting board and slice it into squares. Serve immediately or store for later.
Tips for Best Results
- Use smooth peanut butter for the creamiest texture. Natural peanut butter with oil separation is not recommended, as it can lead to a greasy or grainy texture.
- Sift the powdered sugar if it’s lumpy. This ensures a smooth finish without clumps in the final fudge.
- Work quickly once the powdered sugar is mixed in. The fudge will begin to firm up as it cools, so spreading it into the dish while still warm helps create a smooth, level surface.
- Chill thoroughly before cutting. This makes it much easier to get clean, neat squares.
- Use a hot knife to slice the fudge cleanly. Dip the knife in hot water and dry it before each cut for the best presentation.
Flavor Variations
While this recipe is delicious as-is, it also provides a great foundation for creative variations:
- Chocolate swirl: Melt a small amount of chocolate and swirl it into the fudge before chilling.
- Sea salt topping: Sprinkle a light dusting of flaky sea salt on top for a sweet-and-salty contrast.
- Crunchy twist: Use crunchy peanut butter or stir in chopped peanuts for added texture.
- Layered fudge: Spread half the peanut butter mixture into the dish, top with a layer of melted chocolate, then add the remaining fudge mixture.
- Add-ins: Try stirring in mini marshmallows, chopped pretzels, or even a handful of crushed graham crackers for a s’mores-inspired version.
Serving Suggestions
Peanut butter fudge is perfect for many occasions. Serve it as a bite-sized treat at parties, wrap it up as a homemade gift, or include it in dessert platters during the holidays. You can also enjoy a square or two as an afternoon pick-me-up with a cup of coffee or tea.
It pairs especially well with strong coffee, hot chocolate, or cold milk. Its richness makes even a small piece satisfying, which is why it’s often served in small squares or rectangles.
Storage Instructions
This fudge stores exceptionally well. Once set and sliced, keep it in an airtight container:
- In the refrigerator: Lasts up to 2 weeks. Keep it tightly covered to prevent drying out or absorbing fridge odors.
- At room temperature: Can be kept for up to 5 days in a cool, dry place, especially during cooler months.
- In the freezer: For longer storage, wrap individual squares in plastic wrap and freeze in a sealed container. Thaw in the fridge overnight before serving.
Common Questions
Can I use salted butter?
Yes, you can use salted butter if that’s what you have. Just omit any added salt and taste the mixture before adding vanilla to ensure the flavor is balanced.
Can I make this with natural peanut butter?
Natural peanut butter can be tricky due to its oil separation. For best results, use a commercial smooth peanut butter that doesn’t separate. If you use natural peanut butter, mix it very well before using, and expect a slightly different texture.
Why is my fudge oily or grainy?
This usually happens when using natural peanut butter or not incorporating the powdered sugar thoroughly. Mix well and use stabilized peanut butter for a smooth, creamy finish.
How can I make the fudge firmer or softer?
For firmer fudge, add slightly more powdered sugar. For softer fudge, reduce the sugar slightly or add a tablespoon more peanut butter.
Can I double the recipe?
Absolutely. Just use a larger pan, such as a 9×13 inch dish, and increase all ingredients proportionally. The chilling time may be slightly longer due to the added volume.
