What Ingredients Are in Easiest Peanut Butter Fudge?

This peanut butter fudge uses a short ingredient list, but each ingredient helps create that rich, creamy, melt-in-your-mouth texture.

The butter adds richness, the brown sugar gives the fudge sweetness and depth, the milk helps everything boil into a smooth base, and the peanut butter brings the classic flavor. Vanilla rounds everything out, while confectioners’ sugar thickens and sets the fudge.

Ingredients

½ cup butter
1 package brown sugar, 16 ounces
½ cup milk
¾ cup peanut butter
1 teaspoon vanilla extract
3 ½ cups confectioners’ sugar

When choosing peanut butter, creamy peanut butter works best if you want a smooth, classic fudge texture. Regular shelf-stable peanut butter is usually easier to work with because it blends evenly into the warm sugar mixture.

The confectioners’ sugar is important here. It helps thicken the fudge and gives it that soft, sweet finish. For the smoothest result, make sure it is added to a large mixing bowl before pouring in the hot peanut butter mixture.

How to Make Easiest Peanut Butter Fudge

Making this peanut butter fudge is simple, but the timing matters. Once the sugar mixture is ready, you want to move quickly so everything blends smoothly before it starts to set.

Make the Brown Sugar Mixture

Start by melting the butter in a medium saucepan over medium heat.

Once the butter is melted, stir in the brown sugar and milk. Bring the mixture to a boil, then let it boil for 2 minutes, stirring frequently.

This short boiling step helps dissolve the sugar and gives the fudge its rich, sweet base.

Add the Peanut Butter and Vanilla

Remove the saucepan from the heat.

Stir in the peanut butter and vanilla extract until the mixture is smooth and evenly combined. The peanut butter should melt into the warm sugar mixture, creating a thick and glossy base.

Beat the Fudge Mixture

Place the confectioners’ sugar in a large mixing bowl.

Pour the warm peanut butter mixture over the confectioners’ sugar, then beat everything together with an electric mixer until smooth.

This step is where the fudge really comes together. The mixture will become thick, creamy, and ready to spread into the pan.

Chill and Slice

Spread the fudge mixture into an 8×8-inch pan. Smooth the top as evenly as possible.

Chill until firm, about 1 hour. Once the fudge has set, slice it into squares and serve.

Easiest Peanut Butter Fudge Tips

For the smoothest fudge, have your confectioners’ sugar measured and ready before you start cooking the butter, brown sugar, and milk.

Stir the boiling mixture frequently so the sugar does not stick to the bottom of the saucepan.

If you want cleaner slices, chill the fudge fully before cutting. A sharp knife will help create neat squares.

This recipe makes 32 servings, so it is perfect for sharing, gifting, or adding to a holiday dessert platter.

Easiest Peanut Butter Fudge Substitutions and Variations

One of the best things about peanut butter fudge is how easy it is to customize. The classic version is delicious on its own, but a few simple additions can make it feel brand new.

Chocolate Swirl

Melt a small amount of chocolate and swirl it into the top of the fudge before chilling. Peanut butter and chocolate are always a winning combination.

Crunchy Peanut Butter

Use crunchy peanut butter if you want little bits of peanut throughout the fudge. It gives the soft texture a bit more bite.

Sea Salt Topping

Sprinkle a little flaky sea salt over the top before chilling for a sweet-and-salty finish.

Holiday Add-Ins

For a festive version, add mini chocolate chips, chopped peanuts, crushed pretzels, or holiday sprinkles before the fudge sets.

How to Store Peanut Butter Fudge

Keep peanut butter fudge in an airtight container at room temperature for up to 1 week.

For longer storage, place it in the refrigerator for up to 2 weeks. If stacking the fudge pieces, use parchment paper or waxed paper between layers to keep them from sticking together.

Can You Freeze Peanut Butter Fudge?

Yes, peanut butter fudge freezes well.

Wrap the fudge tightly in wax paper, then wrap it again in aluminum foil. Place the wrapped fudge in a freezer-safe container or add another layer of foil for extra protection.

Freeze for up to 3 months. When you are ready to enjoy it, thaw the fudge in the refrigerator overnight.
