Growing up, peanut butter was practically its own food group in our house. Smooth, creamy, and always stocked in the pantry, it made its way into everything—from sandwiches to cookies and, most memorably, fudge. My first memory of making peanut butter fudge was with my grandma on a chilly December afternoon. No candy thermometer, no complicated steps—just a saucepan, a wooden spoon, and her classic recipe scribbled on a yellowing index card.
That fudge came together in minutes and filled the whole house with the smell of roasted peanuts and warm vanilla. We’d pour it into a buttered dish, press it flat with our palms, and sneak a taste before it had even cooled. It wasn’t just dessert—it was a moment. A memory. A sticky-fingered tradition.
Today, I make this peanut butter fudge whenever I need something quick but comforting. It’s perfect for gifting, holiday platters, or just cutting into neat squares for the fridge when that late-night craving hits. And the best part? No baking, no stress, and no special tools required.

Simple Pantry Staples That Make the Magic
The beauty of peanut butter fudge lies in its simplicity. You won’t need a candy thermometer or any fancy ingredients—just a few pantry basics that come together in under 10 minutes. Here’s what you’ll need:
1 cup unsalted butter
1 cup creamy peanut butter (not natural; use Jif or Skippy for best texture)
1 teaspoon vanilla extract
3 ¾ cups powdered sugar
That’s it! These ingredients deliver a soft, rich texture and balanced sweetness. The peanut butter provides a salty depth, while powdered sugar ensures a smooth, melt-in-your-mouth finish. The butter? It brings the fudge together and adds that classic creaminess you crave in every square.
Quick Tips for Perfect Peanut Butter Fudge
To start, melt the butter and peanut butter together in a saucepan over medium heat. Stir constantly until smooth and bubbling gently—this helps everything bind together. Remove from the heat and stir in the vanilla.
Now here’s the key step: Sift the powdered sugar if it’s clumpy before adding it. Then, stir it into the warm peanut butter mixture. At first, it’ll look too thick—but keep mixing! It should come together like dough.
Press the fudge into a parchment-lined 8×8 pan. Use a spatula or your hands to smooth it out, then chill until set. Within an hour, you’ll have perfect fudge squares ready to slice.

One of the most common questions with peanut butter fudge is: Why is it still soft after chilling? Don’t worry—it’s usually an easy fix. If your fudge won’t firm up, one of these issues is likely the culprit:
Too much butter or not enough sugar: Fudge needs a solid ratio of fat to dry ingredients. Be sure to measure your powdered sugar correctly. Spoon it into your measuring cup and level it off—don’t pack it.
Didn’t heat the mixture long enough: The peanut butter and butter should bubble gently for 1–2 minutes. This step helps the fudge hold together.
Used natural peanut butter: Natural peanut butter contains oil that separates and can cause fudge to stay soft. Always use a processed creamy version like Jif or Skippy.
If you’ve already made the batch and it’s too soft to cut, try chilling it longer or freezing it briefly before slicing. For the next time, adjusting your measurements slightly will solve the problem.
Texture Tips for Rich, Smooth Fudge
If you’re after silky-smooth fudge with just the right amount of firmness, here’s what to do:
Sift powdered sugar before adding. It keeps lumps from forming and makes mixing easier.
Work quickly once the sugar is added—this helps avoid graininess and gives your fudge a clean finish.
Line your pan with parchment to lift the fudge easily once it sets.
Don’t stir too much after removing from heat—once combined, overmixing can affect texture.
Prefer your fudge extra firm? Reduce butter by 2 tablespoons and press the mix in tightly. Like it melt-in-your-mouth soft? Let it set at room temp before refrigerating.
The great thing about peanut butter fudge is how low-maintenance it is. Once set, it doesn’t have to be refrigerated—but doing so can extend its freshness. At room temperature in an airtight container, it lasts up to 7 days. Just be sure to store it in a cool, dry spot away from sunlight or heat, which can cause it to soften too much.
If you live in a warm climate or want a firmer texture, refrigerate it in a sealed container. Place parchment between layers to prevent sticking. When you’re ready to serve, let the pieces sit out for 10 minutes to soften slightly—they’ll be the perfect consistency for slicing or snacking.
How Long Does Peanut Butter Fudge Last?
Properly stored, your fudge can last:
Room temperature: 5–7 days
Refrigerated: Up to 2 weeks
Frozen: Up to 3 months
To freeze, wrap each square in plastic wrap or parchment, then store in a zip-top freezer bag or airtight container. Label with the date. When you’re ready to enjoy it again, thaw in the fridge overnight or at room temp for an hour. The flavor and texture hold up beautifully!
