Recommended Products for This Recipe
After making this fudge countless times, I’ve found a few products that genuinely make the process smoother and the results even better. These are the tools and ingredients I reach for every time.
1. Jif Creamy Peanut Butter
This is my absolute favorite peanut butter for fudge making. The consistency is perfect – not too oily, not too thick – and it melts beautifully with the condensed milk.
Natural peanut butters can make the fudge grainy or separated, but Jif gives you that smooth, creamy texture every single time.
2. USA Pan Nonstick Square Cake Pan
This commercial-grade baking pan distributes heat evenly and has a nonstick coating that makes removing the fudge absolutely effortless.
The straight edges give you perfect square pieces, and it’s sturdy enough to last for years of fudge-making adventures.
3. Reynolds Kitchens Parchment Paper
Quality parchment paper is a total game-changer for fudge. This one doesn’t curl or stick, and you can lift the entire fudge block right out of the pan for clean, easy cutting. It also makes cleanup practically nonexistent.
4. Nielsen-Massey Pure Vanilla Extract
Since this recipe has so few ingredients, each one really shines through. This premium vanilla extract adds incredible depth and warmth to the fudge.
A little goes a long way, and the flavor difference is noticeable.

Step-by-Step Instructions: How to Make Peanut Butter Fudge
Follow these detailed steps for perfect fudge every time. The key is working quickly once the mixture is melted, as it begins to set as it cools.
1. Prepare Your Pan
- Line your 8×8-inch or 9×9-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal
- Smooth out any wrinkles in the parchment to ensure flat, even fudge
- If using aluminum foil, lightly grease it with butter or cooking spray
- Set the prepared pan aside within easy reach of your stovetop
2. Combine Peanut Butter and Condensed Milk
- Place the peanut butter and sweetened condensed milk in your heavy-bottomed saucepan
- Set the heat to medium-low to prevent scorching
- Stir constantly with a wooden spoon or silicone spatula, scraping the bottom and sides of the pan
- Continue stirring until the mixture is completely smooth and combined, about 3-4 minutes
- The mixture should be warm and fluid, not boiling
3. Add the Powdered Sugar
- Remove the pan from heat immediately once the peanut butter mixture is melted
- Sift the powdered sugar directly into the warm mixture to avoid lumps
- Stir vigorously to incorporate the sugar, working quickly as the mixture will begin to thicken
- Continue mixing until completely smooth with no streaks of white sugar visible
- The mixture will become thick and glossy
4. Incorporate Vanilla and Salt
- Add the vanilla extract and a pinch of salt to the fudge mixture
- Stir thoroughly to distribute the vanilla evenly throughout
- Work quickly as the fudge continues to thicken as it cools
- The mixture should be thick but still spreadable at this point
5. Transfer to Pan
- Pour the fudge mixture into your prepared pan immediately
- Use your spatula to spread it evenly into all corners
- Smooth the top with the back of your spoon or an offset spatula
- Press down gently to ensure there are no air pockets
- The surface should be level and smooth for uniform pieces
6. Chill Until Firm
- Place the pan in the refrigerator uncovered for at least 2 hours
- For best results, chill for 3-4 hours or overnight
- The fudge should be completely firm to the touch before cutting
- Avoid covering the fudge while it chills to prevent condensation
- Once set, the fudge will have a matte finish and slice cleanly
7. Cut and Serve
- Lift the fudge out of the pan using the parchment paper overhang
- Place it on a cutting board and peel away the parchment
- Use a sharp knife, wiping it clean between cuts for neat edges
- Cut into 36 squares or your desired size
- Store cut pieces in an airtight container

FAQs About Peanut Butter Fudge
1. Can I use natural peanut butter for this recipe?
I don’t recommend using natural peanut butter for this fudge recipe. Natural peanut butter contains more oil and less stabilizers, which can cause the fudge to become grainy, separate, or not set properly.
Stick with conventional creamy peanut butter like Jif, Skippy, or Peter Pan for the best, smoothest results.
2. Why is my fudge too soft and not setting properly?
Soft fudge usually means the mixture wasn’t combined thoroughly enough or didn’t chill long enough.
Make sure you stir vigorously when adding the powdered sugar to fully incorporate it, and refrigerate the fudge for at least 2-3 hours. If it’s still soft, try freezing it for 30 minutes to firm it up.
3. How do I prevent my fudge from becoming grainy?
Grainy fudge typically results from undissolved sugar crystals. To avoid this, always sift your powdered sugar before adding it to the warm peanut butter mixture.
Stir continuously and vigorously until the mixture is completely smooth with no visible sugar streaks.
4. Can I make this fudge without condensed milk?
Sweetened condensed milk is essential to this recipe’s texture and sweetness. However, you can make a homemade version by simmering 2 cups whole milk with 2/3 cup sugar until reduced by half and thickened.
This takes about 30-40 minutes and requires constant stirring.
5. How long does homemade peanut butter fudge last?
When stored properly in an airtight container, this fudge stays fresh at room temperature for up to 1 week, in the refrigerator for 2-3 weeks, or in the freezer for up to 3 months. Always separate layers with parchment paper to prevent sticking.

This Peanut Butter Fudge has been my trusted companion for countless gatherings, holidays, and simple weeknight cravings. The beauty of this recipe lies in its simplicity and reliability.
