Ingredients You’ll Need

These two ingredients form a perfect duo that balances flavor and texture beautifully. I’ve found that using creamy peanut butter and vanilla frosting ensures the fudge sets just right—no cracks or crumbles here. Don’t worry about hunting down anything fancy, most of this you might already have in your pantry!

• Creamy Peanut Butter: I prefer a classic brand like Jif; avoid natural peanut butter because it has too much oil and won’t set properly.
• Vanilla Frosting: Use your favorite store-bought vanilla frosting—I like Betty Crocker for its smooth texture and flavor.

Variations

One of the things I love about this Easy 2-Ingredient Peanut Butter Fudge Recipe is how versatile it is. Once you’ve got the base down, you can easily tweak it to match your mood or dietary needs. I’ve experimented a bit and it’s always been a hit.

• Chocolate Swirl: When I first tried swirling in some melted chocolate before refrigerating, it instantly took the fudge to a whole new level of decadence.
• Crunchy Peanut Butter: If you prefer a bit of texture, using chunky peanut butter adds a pleasant surprise in every bite.
• Sugar-Free Option: Using a sugar-free vanilla frosting works well if you’re watching sugar intake, but keep in mind the flavor might vary slightly.
• Nut-Free Swap: You can replace peanut butter with sunflower seed butter to suit nut allergies while keeping that creamy richness.

How to Make Easy 2-Ingredient Peanut Butter Fudge Recipe

Step 1: Prep Your Pan Like a Pro

Start by lining a 9×9 (or 8×8) square pan with parchment paper. I like to let the paper hang over the sides so you can easily lift the fudge out when it’s ready—it’s a handy trick that saves a lot of mess and makes cutting a breeze.

Step 2: Combine Ingredients Gently

In a microwave-safe bowl, scoop in your peanut butter and vanilla frosting. Here’s where things get fun: microwave the mixture for 30 seconds, then stir it well. You’ll notice it starts to look glossy and smooth. Microwave another 30 seconds and give it a thorough stir again—that’s the perfect texture you want before setting.

Step 3: Spread and Chill

Pour your fudge mixture into the prepared pan. I like using an offset spatula because it lets me smooth everything out evenly without much fuss. Once it’s perfectly spread, pop it in the fridge for about 2 hours. This step is key—you want the fudge to fully set and become firm enough to slice cleanly.

Step 4: Slice and Enjoy!

Once set, lift the fudge out using the parchment paper edges and slice into bite-sized squares. I find that a sharp knife warmed slightly under hot water helps make the cuts clean without squishing the fudge.

How to Serve Easy 2-Ingredient Peanut Butter Fudge Recipe

Garnishes

I like to sprinkle a tiny pinch of flaky sea salt on top of each square before chilling—it really amps up the peanut butter flavor and adds a lovely contrast. Chopped roasted peanuts or a drizzle of melted chocolate also make fantastic garnishes if you’re feeling fancy.

Side Dishes

This fudge pairs beautifully with a cold glass of milk or a robust cup of coffee. For parties, I’ve served it alongside fresh berries or sliced apples—the combination of creamy fudge and fresh fruit wins every time.

Creative Ways to Present

When I made these for a birthday party, I cut them into fun shapes using small cookie cutters after chilling, then placed them in colorful cupcake liners. It turned the fudge into adorable little bites that everyone loved, especially the kids.

Make Ahead and Storage

Storing Leftovers

I store leftover fudge in an airtight container in the fridge. It keeps perfectly for up to two weeks—and honestly, it barely lasts that long in my house. Keeping it chilled means it stays firm and as delicious as the day you made it.

Freezing

I’ve frozen leftover fudge before when I made a big batch. Just wrap the squares individually in wax paper and place them in a freezer-safe container. When you’re ready to enjoy, let them thaw in the fridge overnight to maintain that creamy texture.

Reheating

Since this fudge is best served chilled, I don’t really recommend reheating. But if you want to soften it up a bit to enjoy more like a spread, a few seconds in the microwave (5-10 seconds) does the trick — just watch carefully so it doesn’t melt completely.
