Easy Peanut Butter Fudge

Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

2 cups creamy peanut butter

1 cup unsalted butter

1 teaspoon vanilla extract

3 ¾ cups powdered sugar

Directions

I line an 8x8-inch square baking dish with parchment paper or lightly grease it.

In a large microwave-safe bowl, I combine the peanut butter and butter.

I microwave the mixture on high for 2 minutes, stir well, then microwave for another 2 minutes until smooth and fully melted.

I stir in the vanilla extract.

Gradually, I add the powdered sugar, mixing until everything is incorporated and the fudge is thick.

I spread the fudge into the prepared dish and smooth the top with a spatula.

I chill it in the refrigerator for at least 2 hours, or until it’s set.

Once firm, I cut it into squares and store it in an airtight container in the fridge.

Variations

I sometimes swirl in a bit of melted chocolate before chilling for a chocolate-peanut butter twist.

For texture, I mix in chopped peanuts or mini chocolate chips after adding the powdered sugar.

I like using crunchy peanut butter instead of creamy for a bit of crunch.

For a festive touch during the holidays, I top the fudge with crushed candy canes or colored sprinkles.

I’ve also tried this with almond butter or sunflower seed butter as a peanut-free option—it works well!

Storage/Reheating

I store the peanut butter fudge in an airtight container in the refrigerator for up to one week. For longer storage, I freeze it in layers separated by parchment paper. When I want to enjoy a piece, I just let it sit at room temperature for a few minutes. There’s no need to reheat—it’s ready to enjoy straight from the fridge or after thawing.

FAQs

How do I know when the fudge is fully set?

I check that the fudge is firm to the touch and holds its shape when cut. This usually takes at least 2 hours in the fridge.

Can I make this fudge on the stovetop instead of the microwave?

Yes, I just melt the butter and peanut butter together over low heat, stirring constantly until smooth. Then I proceed with the rest of the recipe as written.

Why is my fudge oily or greasy?

This can happen if the peanut butter or butter gets too hot. I make sure not to overheat the mixture and stir well between microwave sessions.

Can I use natural peanut butter?

I don’t recommend it. Natural peanut butter tends to separate and doesn’t give the same smooth, firm texture that regular creamy peanut butter does.

Is this fudge gluten-free?

Yes, as long as the peanut butter and vanilla extract are certified gluten-free, this recipe is naturally gluten-free.

Conclusion

This Easy Peanut Butter Fudge is one of those recipes I turn to again and again for its simplicity and amazing flavor. Whether I’m making it for myself, my family, or as a gift, it never fails to impress. With minimal ingredients and no baking required, it’s the perfect treat to whip up any time a craving hits.
