That’s exactly why I fell in love with this 2-ingredient peanut butter fudge. Seriously—just peanut butter and frosting! No fancy equipment, no baking, just pure creamy bliss in minutes. I first made this when my niece randomly showed up craving treats, and now it’s my emergency dessert lifesaver. The best part? It tastes like you spent hours in the kitchen when really, you’ll be done before your microwave finishes beeping. Let’s make some magic!
Why You’ll Love This 2-Ingredient Peanut Butter Fudge
Trust me, this isn’t your average fudge recipe. Here’s why it’s about to become your new obsession:
- No baking required – Your oven gets to stay cold while you whip up magic in the microwave
- Literally two ingredients – Peanut butter and frosting are probably in your pantry right now

I’ve made this at midnight for pregnancy cravings and at 3pm for unexpected company – it never lets me down!
Ingredients for 2-Ingredient Peanut Butter Fudge
Here’s the beautiful part – you only need two things to make this magic happen:
- 18 oz creamy peanut butter (the regular kind, not natural or oily varieties – trust me on this!)
- 16 oz vanilla frosting (grab the pre-made canned stuff – no shame in shortcuts here)
That’s it! Well, besides a microwave and a pan. But those don’t count as ingredients, right? I always keep these two items stocked for emergency fudge situations – which happen more often than I’d like to admit.
How to Make 2-Ingredient Peanut Butter Fudge
Okay, let’s get to the fun part! Making this fudge is so easy you’ll laugh. Just follow these simple steps and you’ll have creamy peanut butter perfection in no time.
Step 1: Prep the Pan
First things first – grab your pan and line it with parchment paper, leaving some extra hanging over the edges. This little trick makes removing the fudge later SO much easier – no stuck-on messes! I use a 9×9-inch pan for thick squares, but an 8×8 works great too if you want them extra thick.
Step 2: Melt and Mix
Now the magic happens! Dump your peanut butter and frosting into a microwave-safe bowl. Microwave for 30 seconds, then stir well. Pop it back in for another 30 seconds and stir again until it’s completely smooth and combined. Careful – the bowl gets hot! If you see any lumps, give it one more quick zap and stir.
Step 3: Chill and Slice
Pour that gorgeous mixture into your prepared pan and smooth it out with a spatula or the back of a spoon. Then comes the hardest part – waiting! Chill it in the fridge for at least 2 hours until firm. Pro tip: For super clean cuts, run your knife under hot water before slicing into squares. Lift out using the parchment handles and enjoy!
Tips for Perfect 2-Ingredient Peanut Butter Fudge
After making this fudge more times than I can count, here are my foolproof tricks for peanut butter perfection:
- Stick to regular peanut butter – The natural kind separates and makes a greasy mess
- Don’t over-microwave – 30-second bursts prevent scorching (burnt peanut butter smells tragic)
- Freeze before slicing – 30 minutes in the freezer gives you razor-sharp clean cuts
- Press it flat – Use wet fingers to smooth the top for that bakery-perfect finish
Oh, and lick the bowl immediately – it’s the chef’s privilege!
Storing and Serving Your 2-Ingredient Peanut Butter Fudge
This fudge keeps beautifully in the fridge – just tuck it into an airtight container with parchment between layers if stacking. It’ll stay creamy and dreamy for up to a week (if it lasts that long!). I love serving mine with a sprinkle of flaky sea salt on top – the salty-sweet combo is unreal. Room temperature is fine for serving, but I personally think it tastes best slightly chilled. Pro tip: Hide a few squares in the back of the fridge for emergencies!
2-Ingredient Peanut Butter Fudge Variations
Want to mix things up? This recipe is crazy flexible! Swap the vanilla frosting for chocolate – instant Reese’s vibes. Crunchy peanut butter adds fun texture (just warn people about the surprise crunch!). For nut allergies, sunflower butter works beautifully (though the color will be darker). Feeling fancy? Stir in mini chocolate chips or crushed pretzels before chilling. My niece loves when I swirl melted chocolate on top – looks fancy but takes 30 seconds. The basic recipe is perfect as-is, but play around once you’ve mastered it!
2-Ingredient Peanut Butter Fudge FAQs
I get asked about this recipe all the time – here are the most common questions with my tried-and-true answers:
Can I use natural peanut butter?
Nope! I learned this the hard way. Natural peanut butter separates and makes a greasy, weird-textured fudge. Stick to regular creamy peanut butter (like Jif or Skippy) for perfect consistency every time.
How long does the fudge keep?
In an airtight container in the fridge, it stays fresh about a week. You can freeze it for up to 2 months – just thaw in the fridge overnight. Pro tip: Write the date on the container because you WILL forget!
Can I use chocolate frosting instead?
Absolutely! Chocolate frosting makes it taste like a Reese’s cup. The ratio stays the same – just swap the vanilla for chocolate. My husband actually prefers this version (more for me when he’s wrong).
Why is my fudge too soft?
Two likely culprits: Either it didn’t chill long enough (be patient!), or you used “natural” peanut butter. If it’s still too soft after proper chilling, pop it in the freezer for 30 minutes before slicing.
Can I add mix-ins?
Go wild! After mixing, stir in mini chocolate chips, crushed pretzels, or even sprinkles. Just keep additions to about ½ cup max or the fudge won’t set properly. My personal favorite? A handful of chopped Reese’s Pieces!
