Ingredients

1 cup unsalted butter
1 cup creamy peanut butter
1 teaspoon vanilla extract
3 1/2 cups powdered sugar, sifted

Preparation Steps

1. Prepare the Pan

Line an 8×8-inch baking pan with parchment paper, leaving a little extra paper hanging over the sides. This will make it much easier to lift the finished fudge from the pan.

Lightly grease the parchment paper and set the pan aside.

2. Melt the Butter and Peanut Butter

Place the butter and creamy peanut butter in a medium saucepan over low to medium-low heat.

Stir constantly as the mixture melts. Continue stirring until the butter and peanut butter are completely combined and the mixture looks smooth and glossy.

Avoid bringing the mixture to a hard boil. Gentle heat is all you need.

3. Add the Vanilla

Remove the saucepan from the heat and immediately stir in the vanilla extract.

Mix until evenly incorporated.

4. Add the Powdered Sugar

Gradually add the sifted powdered sugar to the warm peanut butter mixture.

Stir after each addition until the sugar is fully incorporated. As you continue adding the sugar, the mixture will become noticeably thicker.

Keep mixing until you have a smooth, thick fudge mixture with no visible pockets of powdered sugar.

5. Transfer to the Pan

Immediately spoon the warm fudge mixture into the prepared baking pan.

Use a spatula to spread it evenly into the corners and smooth the surface. Work fairly quickly because the fudge will begin to firm as it cools.

6. Chill Until Firm

Allow the fudge to cool briefly at room temperature, then transfer it to the refrigerator.

Chill for approximately 2 hours, or until completely firm and easy to slice.

7. Cut and Serve

Use the parchment paper to carefully lift the fudge out of the pan.

Place it on a cutting board and use a sharp knife to cut it into small squares. For especially clean cuts, wipe the knife between slices.

Tips for Perfect Peanut Butter Fudge

Use regular creamy peanut butter for the most consistent texture. Natural peanut butter that separates can contain varying amounts of oil and may produce softer or less predictable results.

Sifting the powdered sugar is also worth the extra minute because it helps create a smoother fudge without small sugar lumps.

Be careful not to overheat the peanut butter and butter mixture. Once everything has melted together smoothly, remove it from the heat and continue with the recipe.

Make-Ahead and Storage

Store the peanut butter fudge in an airtight container with parchment paper between the layers.

It can be kept at room temperature in a cool place for several days, or refrigerated for up to about 2 weeks. For longer storage, freeze the individual pieces in a well-sealed freezer-safe container and thaw them in the refrigerator before serving.

Serving Ideas

These little fudge squares are rich, so small portions are perfect. Arrange them on a dessert platter with cookies and other homemade candies, package them in decorative boxes for gifting, or simply enjoy a piece with coffee or a cold glass of milk.

With just butter, peanut butter, vanilla, and powdered sugar, this Never-Fail 4-Ingredient Peanut Butter Fudge from deesviral delivers a wonderfully creamy texture and classic homemade flavor without a complicated candy-making process.
