3 Ingredient Peanut Butter Fudge – Easy & Creamy Recipe

Creating a rich, velvety confection at home does not require a candy thermometer or hours of monitoring a stovetop. This 3 ingredient peanut butter fudge relies on the chemical reaction between sweetened condensed milk and peanut butter to create a dense, melt-in-the-mouth texture that rivals professional confectionery. It is a straightforward process that yields a decadent treat perfect for holiday gift-giving or a quick weekend dessert. By mastering this simple technique, you can produce a consistent, foolproof sweet that balances the saltiness of roasted nuts with the intense sugar profile of condensed milk.

The beauty of this method lies in its reliance on pantry staples. Because the recipe depends on so few components, the quality of your base ingredients will directly influence the final result. Opting for a standard creamy peanut butter ensures the smoothest mouthfeel, while high-quality vanilla extract provides the necessary aromatic depth to round out the flavor. Once you understand the basic ratios, this reliable 3 ingredient peanut butter fudge becomes a versatile foundation for various mix-ins, such as crushed peanuts, sea salt flakes, or chocolate drizzles.

Ingredients

• 14 ounces sweetened condensed milk
• 1 cup creamy peanut butter (do not use natural, oil-separated varieties)
• 1 teaspoon pure vanilla extract

Equipment Needed

• 8×8 inch square baking pan
• Parchment paper or aluminum foil
• Medium saucepan
• Silicone spatula
• Measuring cups and spoons

How To Make

1. Line your 8×8 inch square baking pan with parchment paper or foil, leaving an overhang on the sides to make removing the fudge easier later.
2. Place the medium saucepan over low heat and pour in the sweetened condensed milk.
3. Add the creamy peanut butter to the saucepan.
4. Stir the mixture constantly with a silicone spatula, ensuring the peanut butter is fully incorporated into the milk.
5. Continue cooking over low heat for approximately 5 to 7 minutes, stirring continuously to prevent scorching at the bottom of the pan.
6. Remove the pan from the heat once the mixture is thick, glossy, and pulls away slightly from the sides of the saucepan.
7. Stir in the vanilla extract until fully combined.
8. Pour the mixture into your prepared baking pan, using the spatula to spread it into an even layer.
9. Place the pan in the refrigerator for at least 2 hours, or until the fudge is completely firm to the touch.
10. Lift the fudge out of the pan using the parchment paper edges and cut into 16 equal squares with a sharp knife.

Expert Cooking Tips

• Avoid using natural peanut butter, as the oil separation causes the fudge to remain greasy or soft rather than setting into a firm, sliceable block.
• If you prefer a salty-sweet profile, sprinkle a pinch of flaky sea salt over the top of the fudge immediately after pouring it into the pan.
• Store your finished squares in an airtight container in the refrigerator to maintain the best texture.
• For cleaner slices, run your knife under hot water and wipe it dry between each cut.
• If the fudge feels too soft after chilling, it may need an additional hour in the freezer to firm up properly.

Frequently Asked Questions

Can I use chunky peanut butter?

Yes, you can substitute creamy with chunky peanut butter if you prefer a bit of texture. The setting properties remain the same, but the final squares will have small bits of peanuts throughout.

How long does this fudge stay fresh?

When stored in an airtight container in the refrigerator, this fudge stays fresh for up to two weeks. It can also be frozen for up to three months if wrapped tightly in plastic wrap.

Why is my fudge grainy?

Graininess usually occurs if the mixture was cooked at too high a temperature or if the peanut butter was not fully emulsified. Always keep the heat on low and stir consistently throughout the cooking process.

Can I double the recipe?

You can certainly double the ingredients to fill a 9×13 inch pan. Ensure you use a larger saucepan to accommodate the volume and increase the cooking time slightly to account for the additional heat needed to thicken the mixture.
