Key Ingredients:
Creamy peanut butter – The heart of the fudge, providing rich nutty flavor, natural creaminess, and a smooth, indulgent texture that sets beautifully when chilled.
Vanilla frosting – More than just sweetness, the frosting adds structure and softness, creating a melt-in-your-mouth consistency while balancing the peanut butter’s richness.
The power of simplicity – With only two ingredients, each one truly matters, allowing their flavors to shine without distraction or unnecessary additions.
Balanced sweetness and richness – The natural savory notes of peanut butter paired with the gentle vanilla sweetness create a perfectly harmonious bite.
Consistent texture with minimal effort – These ingredients blend effortlessly, forming a thick, creamy mixture that sets reliably into smooth, sliceable fudge.
Expert Tips:
Use creamy, well-stirred peanut butter – Natural separation can cause uneven texture. Make sure the peanut butter is fully mixed and smooth before combining.
Avoid overly oily peanut butter – Very runny or freshly ground peanut butter can prevent the fudge from setting properly. A stable, creamy variety works best.
Mix thoroughly for a uniform set – Stir until the mixture is completely smooth with no streaks of frosting. Incomplete mixing can lead to soft or crumbly spots.
Warm slightly if needed – If the peanut butter is stiff, microwave it for 10–15 seconds to soften. This helps it blend seamlessly without overworking the mixture.
Press firmly into the pan – Compacting the mixture removes air pockets and ensures clean, sharp slices once chilled.
Chill, don’t rush – Allow enough refrigeration time so the fudge fully sets. Rushing can lead to soft edges and uneven cuts.
Slice with a warm knife – Running the knife under hot water and wiping it dry before slicing creates smooth, professional-looking pieces.
Cut into small squares – This fudge is rich, so smaller portions provide the perfect bite without overwhelming sweetness.
Line the pan generously – Leave parchment overhang on all sides to lift the fudge out easily without cracking.
Store properly for best texture – Keep the fudge chilled for a firm, clean bite, or let it sit briefly at room temperature for a softer, melt-in-your-mouth experience.
2-Ingredient Peanut Butter Fudge
Ingredients
For the Fudge
Creamy peanut butter (2 cups) – Smooth and rich, forming the base of the fudge
Vanilla frosting (1 container, 16 oz) – Adds sweetness, structure, and a soft, melt-in-your-mouth texture
Equipment Needed
8×8-inch baking dish – Ideal size for evenly set fudge
Parchment paper – Makes lifting and slicing the fudge effortless
Instructions
Prepare the pan
Line an 8×8-inch baking dish with parchment paper, leaving a bit of overhang on the sides.
This will make removing the fudge easy once it has set.
Combine the ingredients
In a large mixing bowl, add the peanut butter and vanilla frosting.
Stir until completely smooth and evenly blended.
The mixture should be thick and creamy, similar to soft dough.
Fill the pan
Spoon the mixture into the prepared dish.
Press it firmly into the corners and smooth the surface using a spatula or the back of a spoon.
Chill until firm
Place the pan in the refrigerator and chill for 1½ to 2 hours, or until the fudge is fully set.
For a quicker option, freeze for 45–60 minutes.
Cut and serve
Lift the fudge out of the pan using the parchment paper.
Slice into small squares with a sharp knife and serve.
Important Notes When Making 2-Ingredient Peanut Butter Fudge:
Ingredient ratios matter – This recipe relies on the balance between peanut butter and frosting. Altering the amounts can affect how well the fudge sets and its final texture.
Type of peanut butter affects firmness – Standard creamy peanut butter creates a firm, sliceable fudge, while natural or very oily versions may result in a softer set.
Frosting consistency is key – Use a full, ready-to-use container of vanilla frosting. Reduced-sugar or whipped frostings may not provide the same structure.
Texture sets as it chills – The fudge may feel very soft at first, but it firms up significantly during refrigeration. Avoid adding extra ingredients too early.
Temperature influences slicing – Cold fudge gives clean edges, while slightly softened fudge offers a creamier bite. Adjust based on preference.
This is a rich dessert – Small portions are ideal, as the flavors are intense and satisfying even in bite-sized pieces.
Flavor deepens after resting – Allowing the fudge to sit chilled for a bit before serving helps the peanut butter flavor become more pronounced.
Best served chilled or lightly softened – Too warm and the fudge may lose structure; too cold and it may feel overly firm.
Simple recipe, visible results – Because there are only two ingredients, any inconsistency in mixing or measuring will be noticeable in the final product.
Designed for ease, not baking precision – This is a forgiving, no-bake treat meant to be simple, approachable, and stress-free.
How to Enjoy 2-Ingredient Peanut Butter Fudge After Making
Let it set fully before serving
Once chilled, allow the fudge to rest for a few minutes at room temperature. This softens it slightly and enhances the creamy, melt-in-your-mouth texture.
Slice into small, satisfying portions
This fudge is rich and dense, so smaller squares offer the perfect balance of sweetness and indulgence without feeling overwhelming.
Serve chilled for clean bites
When served straight from the refrigerator, the fudge holds its shape beautifully and delivers a smooth, firm bite with concentrated peanut butter flavor.
Or soften briefly for extra creaminess
Letting the fudge sit out for 5–10 minutes creates a softer texture that melts more quickly on the tongue and highlights the vanilla notes.
Enhance with simple toppings (optional)
A light sprinkle of flaky sea salt, crushed peanuts, or a drizzle of melted chocolate adds contrast and elevates the experience without complicating the dessert.
Pair with something warm or bitter
Enjoy with coffee, tea, or hot chocolate to balance the sweetness and make each bite feel more rounded and satisfying.
Serve as part of a dessert spread
This fudge pairs beautifully with lighter desserts like fruit or cookies, offering a rich counterpoint on a dessert table.
Enjoy as a quick treat or thoughtful gift
Wrapped individually or arranged in a box, these squares make an easy homemade gift that feels personal and comforting.
Savor slowly
Take small bites and let the fudge soften on your tongue to fully appreciate its creamy texture and nostalgic flavor.
Best enjoyed within a few days
While it keeps well when refrigerated, the flavor and texture are at their best within the first few days after making.

Frequently Asked Questions:
Can I use natural peanut butter for this recipe?
You can, but the texture will be softer and less stable. Natural peanut butter tends to separate and contains more oil, which can prevent the fudge from setting firmly unless it’s very well mixed and chilled longer.
Does the type of frosting matter?
Yes. A standard, full-fat vanilla frosting works best. Whipped or reduced-sugar frostings may not set properly and can result in a softer or sticky fudge.
How long does the fudge need to chill before slicing?
The fudge typically sets in 1½ to 2 hours in the refrigerator. For cleaner cuts, chilling overnight is ideal.
Can I add mix-ins without ruining the texture?
Yes, but keep them minimal. Small amounts of chocolate chips, chopped peanuts, or sprinkles work well. Too many add-ins can prevent the fudge from holding together.
How should I store leftover fudge?
Store the fudge in an airtight container in the refrigerator for up to 5 days. For longer storage, it can be frozen and thawed slightly before serving for best texture.
Why does my fudge feel too soft after mixing?
This is normal. The mixture firms up as it chills. Avoid adding extra ingredients too soon—give it at least 1½ hours in the refrigerator before judging the texture.
How can I make sure the mixture blends smoothly?
Use room-temperature peanut butter and frosting, and stir thoroughly until no streaks remain. If needed, briefly soften the peanut butter to make mixing easier.
Should I use a mixer or stir by hand?
Hand-mixing works best. Using a mixer can incorporate too much air, which may lead to a crumbly or uneven texture once set.
What’s the best way to get clean, neat slices?
Chill the fudge completely, then use a sharp knife warmed under hot water and wiped dry between cuts for smooth edges.
Can I speed up the setting process without affecting quality?
Yes. Freezing for 45–60 minutes works well, but avoid leaving it too long or the texture may become overly firm and difficult to slice.
