If you’ve ever wished for a dessert that combines creamy, nutty richness with the ease of just a couple of ingredients, you’re in for a treat. This Two Ingredient Peanut Butter Fudge Recipe is like a little magic trick for your taste buds, bringing together the smooth flavor of peanut butter and the sweet creaminess of vanilla frosting into a simple, melt-in-your-mouth fudge. It’s the perfect solution when you want a homemade treat that feels indulgent yet comes together in minutes with minimal fuss.

Ingredients You’ll Need
What’s wonderful about this recipe is how uncomplicated it is, relying on just two pantry staples that work perfectly together. Each ingredient plays a special role: the peanut butter provides a rich, nutty backbone, while the vanilla frosting adds a silky sweetness and helps create that luscious fudge texture you’ll love.
- 16 oz jar of peanut butter: Choose creamy for that ultra-smooth texture, or chunky if you want a bit of delightful crunch.
- 16 oz container of vanilla frosting: The sweetness and creamy consistency help achieve the perfect fudge softness and balance the peanut butter’s earthiness.
How to Make Two Ingredient Peanut Butter Fudge Recipe
Step 1: Melt the Ingredients
Start by placing the peanut butter and vanilla frosting together in a microwave-safe container. Microwave for one minute to gently soften everything so they can blend beautifully in the next step. This gentle warming helps the flavors start to mingle while preventing scorching.
Step 2: Stir and Heat Again
Give the mixture a good stir to combine all that creamy goodness. Then microwave for one more minute to ensure everything is perfectly melted and smooth. This step is key to achieving a silky consistency before you set it to chill.
Step 3: Pour into Pan
Carefully pour your glossy peanut butter and frosting mixture into a 9×9 glass baking pan. This size sets your fudge in just the right thickness for cutting into perfect squares later — not too thin and not too thick.
Step 4: Smooth and Refrigerate
Use a spatula to smooth the surface so that your fudge sets evenly. Pop it into the refrigerator and let it chill for about an hour until it turns firm and sliceable. This resting time is essential for that classic fudge texture you’re craving.
How to Serve Two Ingredient Peanut Butter Fudge Recipe

Garnishes
While the fudge is delicious on its own, adding a sprinkle of flaky sea salt or a dusting of cocoa powder before chilling can elevate the flavor profile beautifully. Chopped nuts or mini chocolate chips pressed into the surface also add a fun and tasty twist that makes each bite more exciting.
Side Dishes
Pair this fudge with a cold glass of milk or a hot cup of coffee for a comforting and satisfying snack. It also serves as a lovely sweet ending when paired with fresh fruit or a scoop of vanilla ice cream, letting the peanut butter flavor shine as the star.
Creative Ways to Present
Turn your fudge into bite-sized treats by cutting into small squares and laying them out on a pretty platter with decorative cupcake liners. Alternatively, wrap individual pieces in wax paper tied with twine for a charming homemade gift perfect for friends and family.
Make Ahead and Storage
Storing Leftovers
You’ll be happy to know that leftover fudge keeps well stored in an airtight container in the refrigerator for up to two weeks. This makes it a great make-ahead treat to have ready whenever a peanut butter craving hits.
Freezing
If you want to enjoy your peanut butter fudge later on, freezing is an excellent option. Wrap each piece tightly in plastic wrap, then place them in a freezer-safe container. They’ll hold their texture and flavor for up to three months.
Reheating
No need to thaw for long — letting the fudge sit at room temperature for 15-20 minutes makes it soft and chewy again without losing the classic peanut butter fudge texture. You can also microwave briefly in short bursts if you prefer it extra soft.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter will add delightful little bits of peanut texture throughout the fudge, giving each bite an extra layer of crunchiness that’s incredibly satisfying.
Is it possible to make this fudge sugar-free?
You can try substituting the vanilla frosting with a sugar-free alternative, but keep in mind the texture and sweetness might vary slightly since frosting contributes both in this recipe. Experiment with caution and adjust to taste.
How thick should I cut the fudge pieces?
Cutting your fudge into roughly 1-inch squares works best. This size gives you a perfect balance of creamy satisfaction without being too overwhelming or too tiny to enjoy properly.
Can I use peanut butter powder instead of regular peanut butter?
Peanut butter powder doesn’t contain the oils and fats that give classic fudge its texture, so it’s not ideal for this particular recipe. Stick to regular peanut butter for the best results.
How long does it take for the fudge to set properly?
About one hour in the refrigerator is usually enough for the fudge to fully firm up. If your fridge is on the warmer side, you might want to give it a little extra time to ensure a perfect slice.
