Peanut Butter Fudge You’ll Want to Make on Repeat

Last Updated on November 26, 2025 by Souhail

There’s just something magical about peanut butter fudge that feels like a warm hug wrapped in nostalgia. I vividly remember being a kid in upstate New York during the holidays, sneaking pieces of fudge from the cooling tray when I thought no one was looking (spoiler: they always knew). It was always peanut butter fudge that disappeared first — rich, creamy, and just the right amount of sweet with that melt-in-your-mouth texture you can’t help but crave all year long.

This recipe is perfect for those moments when you want something indulgent, quick, and soul-satisfying. It comes together in minutes with simple pantry ingredients and no candy thermometer needed — which is honestly a relief, right? Whether you’re making it for a holiday dessert platter, wrapping it up as a homemade gift, or just treating yourself on a cozy weeknight, this peanut butter fudge delivers every time. It’s got that smooth, silky texture with deep peanut butter flavor and just the right hit of vanilla to make it irresistible.

Why You’ll Absolutely Love This Peanut Butter Fudge

Okay, let’s talk about what makes this peanut butter fudge stand out from the rest. I’ve made dozens of variations over the years (some required candy thermometers, some were gritty, others too sweet), but this version hits that sweet spot — quite literally. It’s quick, foolproof, and absolutely decadent.

Here’s why this recipe works so well:

• No Candy Thermometer Needed
  This is a heat-and-stir kind of deal — no fancy equipment, no guesswork. Perfect for beginner fudge makers or anyone who just wants a low-stress treat.
• Only 5 Ingredients
  You probably have everything on hand already. Just peanut butter, butter, vanilla, powdered sugar, and a pinch of salt. Simple pantry staples that come together in delicious harmony.
• Creamy, Smooth Texture
  Thanks to the warm butter and peanut butter combo, this fudge sets into the perfect consistency — firm yet soft, never crumbly.
• Quick to Make, Quick to Set
  You’ll spend about 10 minutes from start to finish (minus chill time). Great for last-minute dessert needs or spontaneous cravings.
• Customizable for All Kinds of Diets
  Want to make it vegan? Use plant-based butter and natural peanut butter. Gluten-free? Already done! You can even use almond or cashew butter if peanut’s not your thing.
• It’s Make-Ahead Friendly
  This fudge keeps beautifully in the fridge or freezer, so it’s an ideal make-ahead dessert for the holidays — or a stash-you-hide-from-the-family kind of treat. (No judgment.)

Ingredients

• 1 cup unsalted butter

• 1 cup creamy peanut butter

• 1 tsp vanilla extract

• 0.25 tsp salt

• 3.75 cups powdered sugar

Directions

• Start by gathering all your ingredients — this recipe moves quickly once you get going, so having everything prepped and ready makes a big difference.
• In a medium saucepan, add your butter and peanut butter. You’ll want to use creamy peanut butter for the silkiest texture (though crunchy adds a fun twist if you’re into that). Set the pan over medium heat and stir often until everything is melted together and completely smooth. The smell at this point? Heaven.
• As soon as your butter and peanut butter are fully melted and looking glossy, remove the pan from the heat. Stir in your vanilla extract and a pinch of salt — that little bit of salt balances out the sweetness beautifully.
• Now comes the powdered sugar. I like to add it in batches so it blends more easily. Stir vigorously until the mixture is thick, smooth, and fully combined. It’ll take a little muscle here, but it’s worth it!
• Line an 8×8-inch baking dish with parchment paper, making sure the edges hang over for easy lifting later. Pour your fudge mixture into the dish and smooth the top with a spatula. You can add a sprinkle of flaky sea salt on top here if you like.
• Pop the dish into the fridge and let it chill for at least 2 hours. Once it’s firm, lift it out, slice into squares, and try (just try!) not to eat five pieces in one sitting.

Notes

• Use creamy peanut butter for the smoothest texture; natural peanut butter works too but make sure it’s well-stirred.
• To make it vegan, substitute with dairy-free butter and check that your sugar is vegan-friendly.
• Want a salty-sweet twist? Sprinkle flaky sea salt on top before chilling.
• For a chocolate version, swirl in melted chocolate before setting the fudge.
• Store in the fridge for best texture, or freeze for longer shelf life.

Pro Tips for the Dreamiest Fudge Every Time

You don’t need to be a pro baker to master fudge, but here are some insider tips I’ve picked up along the way that’ll help you nail it on the first try:

• Use Creamy, Not Chunky
  For the smoothest texture, use creamy peanut butter. Natural peanut butters work too, but make sure they’re well-stirred and not too oily.
• Don’t Overheat
  When melting the butter and peanut butter together, just let it come together smoothly — don’t let it bubble or scorch. A gentle melt ensures the right consistency.
• Sift the Powdered Sugar (if you can)
  This isn’t mandatory, but sifting helps avoid any clumps. It makes stirring much easier and gives the fudge that silky finish.
• Line Your Pan with Parchment
  This makes lifting and slicing the fudge so much easier — plus, it keeps cleanup a breeze.
• Chill Thoroughly Before Slicing
  Pop it in the fridge for at least 2 hours to firm up completely. Overnight is even better if you can wait that long (I never can).
• Cut with a Hot Knife for Clean Squares
  Run a knife under hot water, dry it, then slice. Repeat as needed. You’ll get those clean, candy-shop-style edges every time.

Fun Twists on Peanut Butter Fudge You’ve Got to Try

One of the reasons I love this peanut butter fudge recipe is that it’s super flexible. Once you’ve nailed the base, you can riff on it to match any flavor mood, holiday, or dietary preference. Here are a few of my favorite variations that add a whole new personality to the fudge — without making it complicated.

Chocolate Swirl Peanut Butter Fudge

If you’re anything like me, the combo of chocolate and peanut butter is a total weakness. To make a swirled version, melt ½ cup of chocolate chips (semisweet or dark) and gently swirl them into the top of the fudge mixture before it sets. Use a toothpick or the back of a spoon to make those pretty marbled streaks. Not only is it gorgeous, but the flavor is also next-level.

Crunchy Peanut Butter Fudge

Want a little texture? Swap in crunchy peanut butter or stir in ½ cup of chopped roasted peanuts right before pouring the mixture into your pan. It gives each bite a satisfying crunch and makes it feel like a grown-up candy bar.

Vegan Peanut Butter Fudge

This one’s easy: use vegan butter and a natural peanut butter (check that it’s just peanuts and salt). Make sure your powdered sugar is vegan too, and you’re good to go. You’ll still get all the creamy, indulgent flavor — just plant-based.

Maple Peanut Butter Fudge

Add 1 tablespoon of pure maple syrup along with the vanilla for a warm, slightly caramel-y twist. It gives the fudge a subtle depth that’s perfect for fall or winter gatherings. Speaking of cozy autumn flavors, if you’re in the mood, don’t miss this spiced and comforting pumpkin ravioli recipe too.

Chocolate-Coated Peanut Butter Fudge

Once your fudge is fully chilled and sliced, dip each square in melted chocolate and let it set on parchment. You’ll end up with something that tastes like a homemade Reese’s — rich, indulgent, and totally gift-worthy.

Sea Salt Peanut Butter Fudge

Sprinkle flaky sea salt over the top of the fudge just before it sets. That little pop of salt enhances the sweetness and adds a gourmet touch without any effort.

Delicious Ways to Serve Peanut Butter Fudge

While I’ve been known to enjoy a square straight from the fridge (no shame), there are plenty of fun and creative ways to serve up this fudge.

Pair it with fresh fruit on a dessert board for a sweet-salty contrast, or add it to your holiday cookie tray alongside festive treats like chocolate mint cookies or apple crisp with oats.

For entertaining, try cutting the fudge into small bite-sized cubes and serving them in mini cupcake liners with a dusting of powdered sugar or cocoa powder. It feels fancy with minimal effort.

If you’re gifting it, wrap squares in wax paper and tuck them into a pretty tin or box. Just be warned: once people try it, they’ll start expecting it every year!

Storing and Reheating (Though You Won’t Need to Reheat It!)

This fudge is a dream when it comes to storage. Here’s how to keep it tasting fresh and fabulous:

• Refrigerator: Store in an airtight container in the fridge for up to 2 weeks. I like separating layers with parchment paper to prevent sticking.
• Freezer: Yep, it freezes like a charm. Just wrap tightly in plastic wrap and place in a freezer-safe container. It’ll keep for up to 3 months. Let it thaw in the fridge overnight before serving.
• Room Temp (Short-Term): If your kitchen isn’t too warm, you can leave it out for a few hours — perfect for parties or gift baskets.

No need to reheat fudge, but if you like a softer bite, let it sit at room temp for 10–15 minutes before serving.

Creative Uses for Leftover Fudge (If You Even Have Any)

If you somehow manage to not eat the entire batch in two days (teach me your ways), here are a few fun ideas to repurpose your peanut butter fudge:

• Fudge Crumbles in Ice Cream
  Chop up leftover fudge and mix it into vanilla or chocolate ice cream. Bonus points if you add a drizzle of chocolate syrup on top.
• Fudge-Stuffed Cookies
  Make a batch of chocolate cookie dough and tuck a cube of fudge inside each ball before baking. Ooey gooey goodness awaits.
• Dessert Parfait Layers
  Layer fudge cubes with whipped cream, berries, and crushed cookies in a glass for a stunning, indulgent dessert.
• Sweet Toast Topper
  Hear me out: a warm slice of toast, a smear of cream cheese or Greek yogurt, and some chopped fudge on top. It’s like dessert for breakfast.
