(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

unsalted butter
milk
packed light brown sugar
creamy peanut butter
pure vanilla extract (optional)
sifted confectioners’ sugar

directions

I start by lining an 8-inch or 9-inch square pan with foil or parchment paper.
In a saucepan over medium heat, I melt the butter, then stir in the milk and brown sugar.
I bring the mixture to a full boil and let it bubble for 2 minutes, stirring occasionally.
I remove the pan from the heat and quickly stir in the peanut butter and vanilla until smooth.
After letting the mixture cool slightly for 5–10 minutes, I beat it with the sifted confectioners’ sugar until smooth.
I press the fudge into the prepared pan, smooth the top, and chill it in the fridge for at least 4 hours until firm.
Once set, I lift the fudge out, cut it into squares, and enjoy.

Variations

I like to stir in chocolate chips or chopped nuts for added texture.
Using crunchy peanut butter instead of creamy gives it a nutty bite.
For a sweeter twist, I sometimes swirl in marshmallow fluff or drizzle melted chocolate on top before chilling.

storage/reheating

I store the fudge in an airtight container at room temperature for up to 2 weeks. For longer storage, I wrap it in plastic wrap and freeze it for up to 3 months. When I’m ready to eat, I thaw it in the fridge to retain its creamy texture.

FAQs

Can I use natural peanut butter?

Yes, but I make sure it’s not too oily. A well-mixed, stable natural peanut butter works best to keep the fudge smooth.

What if I don’t have brown sugar?

If I’m out of brown sugar, I can use white sugar with a bit of molasses or just white sugar in a pinch, though the flavor may be slightly different.

Can I make this in the microwave?

Yes. I melt the butter, milk, and sugar in a microwave-safe bowl, heating in intervals and stirring until smooth before adding the peanut butter and confectioners’ sugar.

How do I know when it’s set?

I let it chill for at least 4 hours. It should be firm to the touch and easy to cut into clean squares.

Is this fudge too sweet?

It is sweet, but the peanut butter balances it well. I sometimes reduce the sugar slightly if I prefer a less sweet version.

Conclusion

This Easy Peanut Butter Fudge is one of my go-to recipes when I want something sweet, simple, and satisfying. It’s nostalgic, quick to make, and always a hit with friends and family. Whether I stick to the classic version or add my own twist, it never disappoints.
