Save to Pinterest There's something almost magical about the moment when butter and peanut butter meet in a warm saucepan and transform into liquid silk. I discovered this fudge on a rainy afternoon when I was hunting through my pantry for something quick to make, and what started as idle curiosity became an obsession. The beauty of it is deceptive—just a handful of ingredients, but somehow they create something so rich and indulgent that a single piece feels like a small luxury. My kitchen filled with the toasty aroma of peanut butter, and I knew immediately this would become a regular visitor to my counter.
I made this for a potluck once without telling anyone what it was, and watching people's faces when they bit into that smooth, peanutty bite was worth every moment. One guest actually closed her eyes, and another immediately asked if I was selling it. That's when I realized this wasn't just candy—it was the kind of thing that makes people feel cared for, that tastes like someone spent real time thinking about their happiness.
Ingredients
- Unsalted butter (1 cup, 225 g): Quality matters here since it's one of just a few players—use something you'd actually eat on toast.
- Creamy peanut butter (1 cup, 250 g): Smooth is the way to go for that melt-in-your-mouth texture; skip chunky unless you're into surprises.
- Pure vanilla extract (1 teaspoon): This small addition rounds out the flavor and keeps the peanut butter from tasting one-note.
- Confectioners sugar (3½ cups, 420 g): Sift it—I learned this the hard way when I skipped this step and ended up with tiny lumps throughout.
Instructions
- Set Up Your Stage:
- Line your 8x8-inch pan with parchment paper, letting it overhang the sides so you can lift the whole thing out later without wrestling with it.
- Marry the Fats:
- Combine butter and peanut butter in a medium saucepan over medium heat, stirring constantly for about 3 to 4 minutes until the two are completely melted and smooth together. You'll know it's right when there are no visible streaks.
- Add the Warmth:
- Pull the pan off the heat and stir in your vanilla extract—the steam rising up will smell incredible.
- Sweeten Gradually:
- Add the sifted confectioners sugar a bit at a time, stirring vigorously each time to avoid lumps. This takes a minute or two, but it's worth the patience—you're aiming for a texture that's smooth and thick, like cookie dough.
- Pour and Smooth:
- Spread the mixture into your prepared pan and use a spatula to even out the top. Don't worry about perfection; rustic looks good here.
- The Hard Part—Wait:
- Refrigerate for at least an hour until the fudge is firm enough to cut cleanly. I usually go longer because I like it very cold.
- Cut and Serve:
- Use the parchment overhang to lift the whole block out, then cut into 36 squares with a sharp knife. It's best eaten cold or at room temperature, and each piece is perfectly bite-sized.
Save to Pinterest I gave a batch of this to a neighbor once who was going through a rough time, and she later told me she'd ration it out piece by piece because it made her feel cared for. That's when food stops being food and becomes something more—a small gesture that says someone was thinking of you.
Playing with Flavor
The base recipe is perfect as-is, but your kitchen is your canvas. I've folded in roasted salted peanuts for crunch, swirled in melted chocolate right before chilling, and even tried almond butter when I was feeling adventurous. Each change subtly shifts the flavor profile, so play around and find what makes your mouth happy.
Storage and Keeping
This fudge is forgiving and friendly about storage. It keeps beautifully in the fridge in an airtight container for a week, and freezes wonderfully for up to two months if you want to get ahead. I like to freeze mine in layers with parchment between them, so I can grab a piece or two without thawing the whole batch.
