2 Ingredient Peanut Butter Fudge

I gotta tell you about this ridiculously simple and indulgent 2 Ingredient Peanut Butter Fudge that’s probably gonna become your new go-to sweet fix. Seriously, just peanut butter and vanilla frosting – nothing more, nothing less. It’s creamy, rich, and perfect for those moments when you want deep peanut buttery goodness without heating up the house or standing over a hot stove. I remember the first time I made this, I kind of eyeballed the frosting (don’t judge me!) and still ended up with a fudge so smooth and dreamy that my kids devoured it before dinner was even on the table. No baking, no mess, just chill and slice. Ideal for last-minute guests or when you crave a little sweet comfort without fuss.

Detailed Ingredients with measures

1 (16-ounce) jar creamy peanut butter Jif or Skippy recommended (Do not use natural) 1 (16-ounce) tub vanilla frosting Just a quick note here: the “do not use natural” part is super important. Natural peanut butter can get all oily and separate, which makes the fudge… well, not fudge-like at all. Stick with classic creamy Jif or Skippy and you’re golden.

Method

Prepare the pan: Line an 8×8-inch square baking pan with parchment paper. I always leave some overhang on the sides, so when the fudge is set, you can just lift it right out without losing your mind scraping around the edges. Combine and melt: In a large microwave-safe bowl, stir together the peanut butter and vanilla frosting. Pop it in the microwave for 30 seconds, then give it a good stir. Sometimes my microwave heats unevenly, so I do another round of 15 to 30 seconds and stir again until everything looks like one smooth, creamy dream. Honestly, don’t stress about getting it perfectly smooth on the first go – a few lumps won’t ruin your fudge, promise! Set and chill: Pour that peanut buttery mixture into your prepared pan, then spread it out evenly with a spatula (or the back of a spoon if you’re like me and never seem to have a spatula ready). Pop it in the fridge for 1 to 2 hours. This part’s key: if you try to slice it too early, you’ll end up with a sticky mess. Been there, done that. Finish and serve: Use the parchment paper “handles” to lift the fudge out of the pan. Slice into squares, serve with a big glass of cold milk, and prepare for happy pants around the table.

Detailed Directions and Instructions

Prepare the Pan

Line an 8×8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal.

Combine and Melt

In a large microwave-safe bowl, mix the peanut butter and vanilla frosting together.

Microwave the mixture for 30 seconds.

Stir well to combine.

Continue microwaving in 15 to 30-second intervals, stirring after each, until the mixture is smooth and fully combined.

Set and Chill

Pour the mixture evenly into the prepared pan.

Spread the mixture with a spatula to smooth the surface.

Refrigerate for 1 to 2 hours until firm.

Finish and Serve

Use the parchment paper overhang to lift the fudge from the pan.

Slice into about 16 squares and serve.

Notes

Use creamy peanut butter brands like Jif or Skippy; do not use natural peanut butter for best texture.

Vanilla frosting should be from a tub, not homemade, for consistent sweetness and smoothness.

Microwave times may vary; stir frequently to prevent overheating.

Store fudge in an airtight container in the refrigerator for up to one week.

Cook techniques

Melting and combining without lumps

So here’s the deal—when you microwave your peanut butter and vanilla frosting, don’t just zap it once and call it a day. You gotta do it in short bursts—30 seconds first, then 15 to 30 seconds increments afterward. This way, you avoid scorching the mixture or ending up with weird clumps. I learned this the hard way when my first batch got all grainy and sad because I blasted it too long all at once. Stir well in between so the warm pockets even out and end up silky smooth.

Using parchment for easy lifting

Ever tried digging around the pan with a knife or spatula to get that fudge out? Total kitchen nightmare. Lining your pan with parchment paper with some overhang on the sides is a game changer. It’s like giving your fudge a comfy little hammock to rest in until you wanna pull it up. Trust me, this tip will save your sanity especially if you’re in a hurry to get those goodies on a plate.

Spreading the fudge evenly

After you pour your melted mix into the pan, use a spatula to smooth it out. If you just dump it and leave it, the fudge might set unevenly – thick blobs on one side, thin edges on the other, all kind of lopsided and uninspired. A quick gentle swipe evens things out for that perfect firm-but-creamy texture throughout. Also, don’t freak if it looks a little shiny or glossy—that’s peanut butter magic in action.

Patience with chilling

I get it, fudge looks amazing and you wanna dive straight into it. But just chill it in the fridge for at least an hour. This waiting time is crucial for it to set up properly. Tried cutting into a fudge that’s still warm? It’s a sticky mess. But when it’s cold and firm, every piece slices right through, neat and tidy—and melts in your mouth like a peanut buttery dream.

FAQ

Can I use natural peanut butter instead of creamy?

Honestly, natural peanut butter often has oils that separate and can make the fudge texture weird and oily. The recipe really shines with creamy, processed peanut butter like Jif or Skippy that mix smoothly with frosting. Tried natural once—crumbly, sad fudge. So stick with the creamy for the best creamy smoothness.

What happens if I skip the parchment paper?

You can try, but good luck! Your fudge will probably stick to the pan like it’s glued there, and you’ll feel like a mad chef prying pieces out with a butter knife and risk ruining the whole batch. Just don’t skip the parchment—your future self will thank you big time.

Can I add anything extra like chocolate or nuts?

Totally! You can sprinkle chopped nuts on top before refrigerating, or gently fold in mini chocolate chips after melting but before chilling for extra texture. Just be mindful not to overdo it since this fudge is meant to be super simple and silky.

How long does the fudge keep? Does it need refrigeration?

Store it in an airtight container in the fridge and it should last up to two weeks. It can get a bit soft at room temp, especially if your kitchen is warm, so refrigeration is your best bet to keep that perfect bite.

Can I make this fudge without a microwave?

Sure! Melt the peanut butter and frosting gently in a double boiler over low heat, stirring often until smooth and combined. Just keep an eye on it so nothing burns or sticks. Slow and steady wins the fudge race here.

Why does the fudge sometimes turn out grainy?

That’s usually a sign of overcooking or not stirring enough. Microwave in short bursts and stir thoroughly until perfectly smooth. Also, using the right type of peanut butter is key—no natural or salty chunky peanut butters, they don’t play nice here.

I once made this for a last-minute potluck and people were legit fighting over pieces. Pro tip: don’t skip the salt, it really balances out the peanut butter’s richness.

You wanna add a bit of crunch? Toss in some crushed pretzels or chopped peanuts right after microwaving your peanut butter and frosting combo.

Those bites of fudge that come with a little chaos taste the best.
