Easy 2-Ingredient Peanut Butter Fudge Recipe

If you’re craving a sweet treat but want to keep things super simple, this Easy 2-Ingredient Peanut Butter Fudge Recipe is absolutely your new best friend. Seriously, when I first tried this, I was amazed at how rich and creamy it turns out with just peanut butter and vanilla frosting. No fancy equipment, no tricky steps—just quick, sweet, and totally satisfying fudge that you can whip up in minutes. Stick around and I’ll share all my tips so your fudge is perfect every single time.

Ingredients You’ll Need

This recipe comes together with just two pantry staples, which is part of what makes it a go-to in my kitchen. The peanut butter gives it that nutty richness, while the vanilla frosting adds the perfect sweetness and creamy texture.

• Creamy Peanut Butter: I love using classic creamy peanut butter like Jif because it blends smoothly and helps the fudge set nicely. I wouldn’t recommend natural peanut butter here—it can make the fudge too soft.
• Vanilla Frosting: A standard store-bought vanilla frosting works great—it adds sweetness and a smooth finish. I usually grab Betty Crocker Vanilla frosting, but feel free to use your favorite brand.

Variations

One of the things I love most about this Easy 2-Ingredient Peanut Butter Fudge Recipe is how easy it is to make it your own. Play around with frosting flavors or add-ins to mix things up depending on what mood you’re in or what you have on hand.

• Chocolate Twist: I’ve mixed in a couple of tablespoons of cocoa powder to the batter for a chocolate peanut butter spin—my family goes nuts for this!
• Nut-Free Version: You can swap peanut butter for sunflower seed butter if you need to avoid nuts; just know the texture might shift slightly.
• Crunchy Delight: If you like a bit of texture, sprinkle mini chocolate chips or crushed peanuts on top before refrigerating.
• Flavored Frosting: Try cream cheese or maple frosting instead of vanilla for a new flavor boost.

How to Make Easy 2-Ingredient Peanut Butter Fudge Recipe

Step 1: Prep Your Pan

Grab a 9×9-inch (or 8×8-inch) square pan and line it with parchment paper. This little step makes a huge difference because it means your fudge won’t stick, and it’s so much easier to lift out once set. Trust me, it saves you from a sticky mess later.

Step 2: Combine Peanut Butter and Frosting

In a microwave-safe bowl, dump in your peanut butter and vanilla frosting. Don’t worry about mixing too much yet—the heat will help soften everything up. Microwave for 30 seconds, pull it out, and give it a good stir. Pop it back in for another 30 seconds, then stir again until it’s all silky smooth and combined.

Step 3: Pour and Smooth

Pour that luscious fudge mixture into your prepared pan. I like to use an offset spatula to smooth it out evenly—makes it look pretty and ensures even thickness for perfect slices.

Step 4: Chill Until Set

Pop the pan into the fridge for at least 2 hours. You’ll want the fudge to be firm enough to slice without getting all melty or crumbly. I usually leave it overnight if I can—patience definitely pays off here.

Step 5: Slice and Enjoy

Once set, use the parchment paper to lift out the block and slice into bite-sized squares. Enjoy your homemade fudge immediately or save for a sweet snack later!

How to Serve Easy 2-Ingredient Peanut Butter Fudge Recipe

Garnishes

I usually keep it simple, but if I’m feeling fancy, I sprinkle a little sea salt on top before chilling—it creates that salty-sweet magic I just can’t resist. Sometimes a dusting of cocoa powder or crushed peanuts works wonders too, especially if you’re serving it at a party.

Side Dishes

This fudge pairs wonderfully with a cup of strong coffee or a glass of cold milk. For a snack platter, I love serving it alongside fresh fruit like apple slices or grapes—it’s a perfect balance of decadent and fresh.

Creative Ways to Present

When I’ve brought this fudge to gatherings, I like to cut it into fun shapes using cookie cutters or layer it in a clear dessert jar with chopped nuts and mini marshmallows for a festive look. Wrapping individual squares in colorful parchment makes for an adorable, shareable gift too.

Make Ahead and Storage

Storing Leftovers

Store your peanut butter fudge in an airtight container in the fridge—it keeps beautifully for up to two weeks. I always layer pieces with wax paper so they don’t stick together, which makes grabbing a quick bite way easier.

Freezing

If you want to make a big batch ahead of time, this fudge freezes well. Wrap the pieces tightly in plastic wrap and place them in a freezer-safe container. When you’re ready to eat, just thaw in the fridge overnight.

Reheating

I usually enjoy this fudge straight from the fridge, but if you prefer it a little softer, you can microwave a square for about 5-7 seconds. Be careful not to overheat or it might melt too much and lose that fudge texture.
