Why You’ll Love It
This fudge stands out for its effortless preparation and irresistible results. With no fancy equipment or candy thermometers required, you can whip up a pan with just a handful of pantry staples and a few minutes at the stove or microwave. Each piece is creamy, with a melt-in-your-mouth texture that contrasts beautifully with its slightly dense, almost truffle-like structure.
Peanut butter lovers will adore the depth of flavor, while those new to fudge will appreciate how quickly it comes together and how perfectly it sets—making it just as appropriate for last-minute gifts as for planned dessert spreads.
Key Ingredients
- 2 cups granulated sugar
- 1/2 cup milk
- 1 cup creamy peanut butter
- 1/2 cup unsalted butter
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- Optional: 1/2 cup chopped peanuts, mini chocolate chips, or flaky sea salt for finishing
Preparation
To make classic peanut butter fudge, start by lining an eight-inch square pan with parchment or foil, leaving a bit of overhang for easy removal later. In a medium saucepan over medium heat, combine the sugar and milk, stirring until the mixture is fully dissolved and smooth.
Bring to a gentle boil, adjusting the heat to avoid burning, and let it bubble for two to three minutes—this step ensures the fudge will set to a firm yet creamy consistency.
Remove the pan from the heat and immediately stir in the butter and peanut butter, mixing until everything is melted and forms a cohesive, luscious base.
Add the vanilla and salt, stirring to incorporate, and if desired, fold in chopped peanuts or chocolate chips for extra texture. Quickly pour the mixture into the prepared pan, smoothing it into an even layer with a spatula.
Allow the fudge to cool at room temperature for at least two hours, or place it in the refrigerator for a quicker set. Once firm, lift the fudge out using the parchment, and slice into squares or diamonds for serving. For a festive or gourmet finish, sprinkle with sea salt or a handful of extra chopped peanuts while still slightly warm.
Technique, Tips & Tricks
Peanut butter fudge rewards a light hand—once the sugar and milk have boiled, it’s important to work fast so the mixture stays pourable and creamy. Use a sturdy spatula to scrape the sides of the pot, and always have your pan prepared before you start, as the fudge sets quickly.
For ultra-smooth results, sift the sugar to eliminate any clumps, and measure the peanut butter by weight (if possible) for perfect consistency.
If you crave a denser, more crumbly texture, cook the sugar and milk a minute longer, but for a softer, almost silky fudge, stick to the minimum boiling time.
Creamy peanut butter ensures a smooth bite, while chunky works if you love a little crunch. For richer notes, try browning the butter before adding, or swirl in a little honey for a flavor twist.
A microwave version works just as well—combine sugar, milk, and butter in a microwave-safe bowl, heat in timed bursts until bubbling, then proceed as above. The fudge keeps well for a week or more, wrapped tightly, making it perfect for advance preparations or crowd-sized batches.
Substitutions and Variations
Peanut butter fudge is endlessly adaptable. If you’re craving a chocolate-peanut combination, swirl melted dark or milk chocolate into the top before setting, or add cocoa powder with the peanut butter for a marble effect. Almond or cashew butter makes a sophisticated variation, while sunbutter offers a nut-free option for those with allergies.
For festive holidays, press sprinkles or colored sugar onto the surface before the fudge cools, or use decorative molds for shapes. Layer peanut butter fudge with classic chocolate fudge for a two-tone treat, or add mini marshmallows and swirl for a playful, textured finish.
Replace half the sugar with brown sugar for a deeper caramel tone, or add a touch of espresso powder for grown-up depth. Dietary needs can be met with plant-based butters, almond milk, or sugar substitutes—just be mindful of ratios for best setting.
Serving Suggestions
Peanut butter fudge is at home on any dessert tray, cut into tidy squares and arranged with cookies, truffles, or salted caramels for variety.
For gifting, pack pieces into decorative tins, small boxes, or cellophane bags tied with ribbon, making sure to separate layers with wax paper to prevent sticking.
The fudge is a welcome treat alongside coffee or tea for afternoon breaks, or set out as a sweet offering at parties, holiday gatherings, or family movie nights. For special occasions, serve as petit fours or pair with fresh berries and whipped cream for an effortless, elegant dessert.
For bake sales, peanut butter fudge’s rich flavor and easy slicing make it a top seller, and it travels well for picnics, lunchboxes, or road trips. Leftovers can be chopped and mixed into ice cream, brownies, or milkshakes for a decadent twist.
