Ingredients You’ll Need
This easy peanut butter fudge requires just three ingredients:
- 1 can (14 ounces) sweetened condensed milk
- 2 cups peanut butter chips (approximately 12 ounces)
- ½ cup creamy peanut butter
Ingredient Notes
Sweetened Condensed Milk: Creates the smooth, creamy consistency and adds sweetness. Make sure you’re using sweetened condensed milk, not evaporated milk.
Peanut Butter Chips: Provide concentrated peanut butter flavor and help the fudge become firm after chilling.
Creamy Peanut Butter: Adds richness and a smooth texture. Regular shelf-stable peanut butter generally works better than natural varieties that separate easily.
How to Make 3-Ingredient Peanut Butter Fudge
Making homemade peanut butter fudge couldn’t be much easier. Follow these simple steps for a rich, creamy treat.
Step 1: Prepare Your Baking Pan
Line an 8×8-inch square baking pan with parchment paper.
Leave a little parchment hanging over two sides. This makes lifting the finished fudge out of the pan much easier.
Set the prepared pan aside.
Step 2: Combine the Ingredients
In a medium microwave-safe bowl, combine the sweetened condensed milk, peanut butter chips, and creamy peanut butter.
Stir briefly to distribute the ingredients.
The mixture will look thick initially, but it will become smooth as everything melts.
Step 3: Microwave Until Smooth
Microwave the mixture on high for one minute.
Carefully remove the bowl and stir thoroughly.
If the peanut butter chips haven’t completely melted, microwave in additional 15-second intervals, stirring after each.
Continue until the mixture is smooth and creamy.
Avoid overheating, which can make the chips thick or grainy.
Step 4: Spread Into the Pan
Immediately transfer the melted peanut butter mixture to your prepared baking pan.
Use a rubber spatula to spread it evenly into the corners.
Smooth the surface so the fudge has an even thickness.
Step 5: Refrigerate Until Firm
Place the pan in the refrigerator for at least two hours.
The fudge should become firm enough to slice into neat squares.
If the center still feels soft, refrigerate for another hour or until completely set.
Step 6: Slice and Serve
Lift the chilled fudge from the pan using the parchment paper.
Transfer it to a cutting board and cut into approximately 16–20 squares.
For cleaner cuts, use a sharp knife and wipe the blade between slices.
Serve chilled or allow the squares to soften slightly at room temperature before enjoying.
Tips for Perfect Peanut Butter Fudge
Use the correct milk. Sweetened condensed milk is essential. Evaporated milk is thinner and won’t produce the same texture.
Don’t overheat the chips. Short microwave intervals help prevent graininess and overheating.
Choose creamy peanut butter. Regular creamy peanut butter gives the most consistent results.
Measure carefully. Too much peanut butter or condensed milk can affect how firmly the fudge sets.
Allow enough chilling time. Don’t rush the refrigeration step. The fudge needs time to become sliceable.
Line your pan. Parchment paper prevents sticking and makes removing the fudge much easier.
Easy Peanut Butter Fudge Variations
The classic three-ingredient recipe is delicious, but you can easily customize it.
Chocolate Peanut Butter Fudge: Drizzle melted chocolate over the top for a delicious chocolate-peanut butter combination.
Salted Peanut Butter Fudge: Sprinkle a little flaky sea salt over the warm mixture before chilling.
Crunchy Peanut Butter Fudge: Replace creamy peanut butter with crunchy peanut butter for extra texture.
Christmas Peanut Butter Fudge: Add festive red and green sprinkles before refrigerating.
These additions are optional and will change the original three-ingredient recipe.
How to Store Homemade Peanut Butter Fudge
Refrigerator: Store the fudge in an airtight container for up to two weeks for best quality. Separate layers with parchment paper to prevent sticking.
Freezer: Place the squares in a freezer-safe container and freeze for up to 2–3 months.
Thawing: Transfer frozen fudge to the refrigerator until thawed.
For serving, the fudge can sit briefly at room temperature, but refrigeration is recommended for longer storage.
