Ingredients You’ll Need

That’s literally it. Three things. Here’s how they break down:

Ingredient	Amount	Notes
Unsalted butter	1 cup	Use real butter, not margarine
Creamy peanut butter	1 cup	Standard shelf-stable works best
Powdered sugar, sifted	3 cups	Measure before sifting

A quick note on the peanut butter: stick with the regular creamy kind like Jif or Skippy. Natural peanut butter (the kind that separates) tends to make the fudge oily and harder to set. Save the fancy stuff for your toast.

How to Make 3 Ingredient Peanut Butter Fudge

This simple fudge recipe comes together in a handful of easy steps. No candy thermometer, no double boiler, no stress. Let’s go.

Step 1: Prep Your Pan

Line an 8×8-inch pan with foil or parchment paper, then give it a light spray of non-stick cooking spray. This step saves you so much grief later when it’s time to lift the fudge out.

Set the pan aside while you get the good stuff melted. Pro tip: let the parchment hang over the sides a bit so you have little “handles” to pull the whole slab out easily.

Step 2: Melt the Butter and Peanut Butter

Combine the butter and creamy peanut butter in a microwave-safe bowl. Pop it in the microwave for 1 minute, then give it a really good stir.

If it’s not fully melted and smooth, heat for another 30 seconds. You’re looking for a glossy, combined mixture with no visible chunks. It should smell absolutely incredible at this point — buttery and nutty and warm.

Step 3: Mix in the Powdered Sugar

Pour that melted mixture into the bowl of your stand mixer. Add in all 3 cups of sifted powdered sugar.

Using the paddle attachment, mix on low speed until everything is fully combined and smooth. Starting on low keeps powdered sugar from exploding all over your kitchen. Trust me on this one.

“The dough will look almost like a thick cookie batter at this stage — that’s exactly what you want.”

Step 4: Transfer and Press Into the Pan

Scoop the fudge mixture into your prepared pan. Use a spatula (or your hands if you’re brave — it’s a little warm) to press it evenly into the bottom.

You want a nice flat, even layer so every square sets up uniformly. Smooth the top as much as you can. Perfectionists, this is your moment to shine.

Step 5: Let It Set

Here’s the hardest part: waiting. Allow the fudge to set at room temperature for about 4 hours. If you’re impatient (same), pop it in the refrigerator for about 2 hours instead.

You’ll know it’s ready when it feels firm to the touch and holds its shape when you press a corner. Don’t rush this step or you’ll end up with a peanut butter puddle instead of peanut butter candy.

Step 6: Slice and Enjoy

Once set, lift the fudge out using your parchment handles and transfer it to a cutting board. Slice into squares with a sharp knife, wiping the blade between cuts for cleaner edges.

Then stand back and admire your work, because this no bake dessert looks way more impressive than the effort it took.

Expert Tips, Variations, and Troubleshooting

Tips for Perfect Fudge Every Time

Always sift your powdered sugar before measuring. It breaks up any clumps and gives you that silky smooth texture in the finished fudge. Skipping this step can leave you with a gritty bite.

Use room temperature butter if possible before melting — it speeds up the melting process and helps everything combine more evenly. Small effort, big payoff.

For a salty-sweet version that is absolutely addictive, sprinkle a little flaky sea salt over the top right before it sets. It makes this simple fudge recipe taste genuinely gourmet.

Fun Variations to Try

Chocolate swirl: Melt a handful of chocolate chips and drizzle over the top before it sets, then use a toothpick to swirl. Your friends will think you went to pastry school.

Crunchy peanut butter version: Swap in chunky peanut butter for some added texture. It gives the fudge little pockets of crunch that are totally satisfying.

Holiday edition: Press festive sprinkles into the top before refrigerating. This peanut butter candy makes a gorgeous edible gift during the holidays.

Troubleshooting Common Issues

Fudge won’t set firm? It likely needs more time. Give it another hour in the fridge. If it’s still soft, the powdered sugar ratio may have been off — make sure you’re measuring before sifting.

Fudge is too crumbly? This usually means there’s a touch too much powdered sugar. Next time, start with 2.5 cups and add more as needed until the texture is smooth and pliable but not sticky.

Grainy texture? Make sure you’re using standard creamy peanut butter and that your powdered sugar was properly sifted. Natural peanut butter can separate during mixing and cause graininess.

Storage Instructions

Storage Method	Container	How Long
Room temperature	Airtight container	Up to 3 days
Refrigerator	Airtight container	Up to 2 weeks
Freezer	Freezer bag or container	Up to 3 months

Reheating and No-Waste Tips

If you store the fudge in the fridge, let it sit at room temperature for 10 to 15 minutes before eating. Cold fudge is a little firm straight from the fridge — a few minutes out and it gets back to that perfect texture.

To freeze, layer the fudge squares between sheets of parchment paper so they don’t stick together. Thaw in the refrigerator overnight or on the counter for about an hour.

Got crumbly edge pieces from cutting? Crumble them over vanilla ice cream. No waste, all flavor. You’re basically a kitchen genius at this point.
