Ingredients You’ll Need

The beauty of this recipe lies in its simplicity, using just two pantry staples that blend beautifully together to create a rich, sweet fudge. When shopping, look for creamy peanut butter that you love—its flavor really shines through—and a classic vanilla frosting that balances the peanut butter’s nuttiness.

Creamy Peanut Butter: Opt for a natural or regular creamy peanut butter, but make sure it’s smooth so the fudge texture stays silky without any grit.
Vanilla Frosting: I usually reach for a good-quality canned vanilla frosting—something not overly sweet with a smooth consistency to blend perfectly with the peanut butter.

Variations

I love tweaking this Easy 2-Ingredient Peanut Butter Fudge Recipe depending on the occasion or what I have on hand. It’s such a flexible base that lets you get creative and make it your own.

Chocolate Swirl: Adding a few tablespoons of melted chocolate chips swirled in before setting adds a decadent touch. I tried this last Christmas and it was an instant hit!
Crunchy Peanut Butter: Sometimes I swap creamy for crunchy peanut butter to add texture—just don’t blend too aggressively to keep those peanut bits intact.
Nut-Free Variation: For friends with allergies, I’ve used sunflower seed butter instead of peanut butter, and it works surprisingly well as a substitute.
Nut Toppings: Sprinkling chopped peanuts or roasted almonds on top right after spreading the mixture creates a lovely crunch and look.

How to Make Easy 2-Ingredient Peanut Butter Fudge Recipe

Step 1: Mix Your Ingredients Until Smooth

Start by scooping the peanut butter and vanilla frosting into a medium mixing bowl. Using a hand mixer or sturdy spoon, blend everything together until it’s completely smooth and creamy — no lumps! This usually takes about 2-3 minutes with a mixer, and the key here is patience. If it’s hard to stir at first, a brief 10-15 second zap in the microwave can soften the peanut butter and make mixing easier.

Step 2: Press Into a Pan and Chill

Line an 8×8-inch baking dish with parchment paper or lightly grease it so your fudge won’t stick. Spread the creamy mixture evenly in the pan with a spatula, smoothing out the top. Then pop it in the fridge for at least 2 hours to firm up. Sometimes I give it an extra little chill overnight if I want that perfect sliceable texture.

Step 3: Cut Into Bite-Sized Pieces and Enjoy

Once your fudge is set and firm, lift it out with the parchment and transfer to a cutting board. Use a sharp knife to slice into small squares, about 1-inch pieces work great for just the right bite size. If the fudge feels sticky, running your knife under hot water first helps cut clean slices. Serve immediately or store for later snacking!

How to Serve Easy 2-Ingredient Peanut Butter Fudge Recipe

Three white bowls are neatly placed on a white marbled surface. The bowl at the bottom holds a thick, fluffy white spread with soft peaks and creamy texture. The bowl on the left contains a smooth, light brown spread with gentle swirls on top, showing a creamy and dense consistency. The bowl on the right is filled with small, white, grainy curds that look soft and crumbly. Each bowl's contents have distinct textures and shades but share a neutral, light color palette. photo taken with an iphone --ar 4:5 --v 7

Garnishes

For garnishes, I often sprinkle chopped peanuts or a pinch of sea salt on top before chilling to add that salty-sweet contrast that makes every bite pop. Sometimes, I also drizzle a little melted dark chocolate over the fudge before it sets to make it feel extra special.

Side Dishes

This fudge pairs beautifully with a hot cup of coffee or creamy milk for a cozy afternoon snack. I also love serving it alongside fresh fruit like sliced apples or bananas for a balanced, satisfying treat.

Creative Ways to Present

When I bring this Easy 2-Ingredient Peanut Butter Fudge Recipe to parties, I like to package small squares in decorative tins with parchment paper or layer them in mini cupcake liners. It makes for an adorable gift and everyone always asks for the recipe!

Make Ahead and Storage

Storing Leftovers

I keep leftover fudge stored in an airtight container in the fridge; it stays fresh for up to two weeks this way. When you want a quick snack, just grab a piece or two, and you’re golden.

Freezing

Freezing is a great option if you want to stash some fudge for a later date. I wrap individual pieces in plastic wrap and place them in a freezer-safe bag. When I’m ready to enjoy, I let them thaw in the fridge overnight to keep their creamy texture intact.

Reheating

This fudge is best served cold or at room temperature, so I don’t typically reheat it. But if it’s too firm from the fridge, just leaving it out for 10 minutes softens it perfectly for a melt-in-your-mouth experience.

FAQs

Can I use natural peanut butter in this Easy 2-Ingredient Peanut Butter Fudge Recipe?

Absolutely! Natural peanut butter works well, but it may change the texture slightly since it tends to be less creamy and more oily. Just stir it well before mixing and consider chilling a bit longer for firm fudge.
Do I have to use store-bought frosting for this fudge?

Store-bought vanilla frosting is the easiest option here and guarantees the right sweetness and texture. However, if you want to make your own frosting, just be sure it’s thick and creamy enough to blend smoothly with peanut butter.
How long does the Easy 2-Ingredient Peanut Butter Fudge last?

If stored in an airtight container in the fridge, this fudge will stay good for up to two weeks. Just keep an eye out for any changes in texture or smell to ensure it’s fresh.
Can I add other flavors to the fudge?

Yes! Adding a dash of cinnamon, a few drops of vanilla extract, or even some mini chocolate chips can personalize this fudge wonderfully. Just mix them in after blending your two main ingredients.
