Ingredients for 2 Ingredient Peanut Butter Fudge
All ingredients for this easy 2-ingredient peanut butter fudge recipe are shown in the pic below, and special notes are made in the bulleted list to assist you.
- Peanut butter. Use commercial brands like Jif or Skippy for best results.
- Sweetened condensed milk: This adds both sweetness and the perfect fudgy texture. Don't substitute evaporated milk - it's not the same!
See the printable recipe card for quantities and a complete list of ingredients.
How to make it
- Line an 8x8-inch baking pan with parchment paper, letting the paper overhang the sides for easy removal. You'll need about 18 ounces of creamy peanut butter and one 14-ounce can of sweetened condensed milk.
- Heat the peanut butter in a medium microwave-safe bowl until completely melted and smooth, about 1 minute total, stirring in 30-second intervals to prevent overheating. Note: Alternatively, melt the peanut butter in a medium saucepan over medium-low heat, stirring constantly.
- Pour the entire can of sweetened condensed milk into the melted peanut butter. Stir or whisk vigorously until the mixture is completely smooth and well combined, about 1-2 minutes. The fudge mixture should be thick but pourable.
- Immediately pour the mixture into your prepared pan. Use a rubber spatula to spread it evenly into the corners. Gently tap the pan on the counter 4-5 times to remove any air bubbles and smooth the top.
- Let the fudge stand at room temperature for 30 minutes to begin setting. This gradual cooling helps prevent crystallization. Transfer to the refrigerator and chill for 2-3 hours until completely firm.
- Once firm, use the parchment paper overhang to lift the fudge from the pan. For clean slices, run a large sharp knife under hot water, dry it completely, then cut the fudge into 1-inch squares. Note: Clean and reheat the knife between cuts for the neatest edges.
Top tips
- Use commercial peanut butter. Brands like Jif or Skippy are best for fudge making. Natural peanut butter can separate and make your fudge grainy or prevent it from setting properly.
- Temperature matters. Room-temperature ingredients create the smoothest fudge. Cold ingredients can cause the mixture to seize up, while overheated peanut butter can become grainy.
- Take your time setting. Let the fudge cool gradually at room temperature before refrigerating. This prevents crystallization and ensures the silky-smooth texture we're looking for.
- Master the cutting technique. Dip your knife in hot water for professional-looking squares and dry it between each cut. This prevents the fudge from sticking and gives you clean edges.
Variations
- Chocolate Swirl: Pour melted chocolate chips or white chocolate chips over the top and swirl with a knife.
- Sea Salt: Sprinkle flaky sea salt on top before setting for sweet-salty perfection.
- Nutty Crunch: Press chopped roasted peanuts or shredded coconut into the top before chilling.
- S'mores Style: Top with mini marshmallows and graham cracker crumbs.
- Cookie Butter: Replace half the peanut butter with Biscoff spread.
- Birthday Fudge: Add colorful sprinkles before the fudge sets.
Storage instructions
Store fudge squares in an airtight container, separating layers with wax paper. Keep refrigerated for up to 2 weeks.
For longer storage, wrap well and freeze for up to 2 months. Let thaw overnight in the refrigerator before serving.
Recipe FAQs
Commercial peanut butter works best as natural varieties can separate and affect texture.
The fudge will take approximately 2-3 hours to set in the refrigerator. If you're in a rush, you can chill it in the freezer for about an hour.
Absolutely! You can add chopped nuts, sprinkles, or even a drizzle of chocolate on top of the fudge before it sets.

Can you use the “WOW” peanut butter in this recipe to make it nut free, I try to find good recipes for my sister and grand daughter since they are nut allergic and your recipe would be easy and fast to use, please let me know, many thanks and prayers, I try to find many recipes for others that have allergies, have a blessed day.
Jeri Walker says
Hi Tim! Yes, WOW butter will work great in this recipe for a nut-free version. It melts and sets almost the same as peanut butter. I love that you're making this for your sister and granddaughter-what a sweet gift! 🙂

This looks easy enough! I am going to try to make a low carb version using a sugar free sweetened condensed coconut milk I found on Amazon. It's called Nature's Charm Sweetened Condensed Coconut milk sugar free. Great for diabetics using this as my husband is a diabetic.
Jeri Walker says
Great idea! Let me know how it turns out! 🙂
Beckie says
How much PB?
Jeri Walker says
