Peanut Butter Fudge Recipe With White Chocolate Chips: Rich and Smooth Melt-Away Squares

This fudge recipe delivers rich, smooth squares with a perfect balance of peanut butter and sweet white chocolate. I developed this method after testing numerous versions to get the texture just right.

The key is precise temperature control and thorough mixing to achieve that signature melt-away consistency. White chocolate chips add creamy sweetness that complements the nutty depth of peanut butter beautifully.

You’ll end up with a batch of fudge that’s firm enough to hold its shape yet soft enough to dissolve on the tongue. The white chocolate creates visible speckles throughout, making every piece visually appealing.

Ideal for gifting, holiday trays, or satisfying that afternoon sweet tooth. This recipe works every time.

Ingredients for Peanut Butter Fudge Recipe with White Chocolate Chips

These nine ingredients create rich, velvety peanut butter fudge with white chocolate speckles throughout.

The peanut butter is non-negotiable here—Jif or Skippy creamy give the smoothest texture. Avoid natural or reduced-fat varieties, as they can separate and ruin the consistency. Ghirardelli or Guittard white chocolate chips melt beautifully and hold their shape. Evaporated milk should be full-fat for creaminess, and Carnation is the most reliable brand at any grocery store.

No marshmallow fluff? Mini marshmallows melted into the mixture work as a substitute. Out of evaporated milk? Heavy cream reduced by half (simmer 1 cup down to 1/2 cup) can replace it in a pinch. For a firmer fudge, reduce the heavy cream by 1 tbsp. The vanilla extract should be pure, not imitation—McCormick or Nielsen-Massey are solid choices.

Store fudge in an airtight container at room temperature for up to 2 weeks. For longer storage, freeze for up to 3 months. Layer parchment between pieces to prevent sticking. Bring to room temperature before serving for that perfect melt-away consistency.

Step-by-Step Instructions for Peanut Butter Fudge With White Chocolate Chips

Master this foolproof method for creamy, melt-in-your-mouth fudge with perfect texture every time.

Step 1: Prepare the Sugar Mixture

In a large, heavy-bottomed saucepan, combine the 3 cups Granulated Sugar, 1 can Evaporated Milk, and 0.5 cup Unsalted Butter cut into pieces. Place over medium-high heat and stir constantly with a wooden spoon to prevent scorching.

Bring the mixture to a full rolling boil, then continue boiling for exactly 4-5 minutes. You’re looking for the sugar to reach the soft-ball stage at 234-240°F on a candy thermometer. Remove from heat immediately once the temperature is reached to prevent overcooking.

Step 2: Incorporate the Marshmallow and Peanut Butter

Off the heat, quickly stir in the 1 jar Marshmallow Fluff and 1.5 cups Peanut Butter until completely smooth. The residual heat will help melt these ingredients together seamlessly. This step must be done efficiently while the sugar mixture is still hot.

Add the 2 tsp Vanilla Extract and 0.25 tsp Salt, mixing thoroughly to distribute the flavors evenly. The mixture should now have a glossy sheen and a thick, pudding-like consistency that pulls away slightly from the sides of the pan.

Step 3: Fold in the White Chocolate Chips

Allow the mixture to cool for 2-3 minutes at room temperature, stirring occasionally. Then fold in the 2 cups White Chocolate Chips until they’re evenly distributed and mostly melted. The residual heat will soften them without completely incorporating.

If using, pour in the 0.25 cup Heavy Cream and stir until fully combined. This adds an extra layer of richness and ensures your fudge will have that ultra-smooth, velvety texture that melts on the tongue.

Step 4: Set and Cut the Fudge

Immediately pour the fudge into a greased 8×8-inch or 9×9-inch baking pan, spreading evenly with a spatula. The mixture will be thick but still pourable. For easiest removal, line your pan with parchment paper before adding the fudge.

Let cool to room temperature, then refrigerate for at least 2 hours until completely set. Once firm, remove from the pan and cut into 1-inch squares using a sharp knife. For clean cuts, dip the knife in hot water and wipe between each slice. Store in an airtight container at room temperature for up to 2 weeks.

Storing and Reheating peanut butter fudge recipe with white chocolate chips

Room Temperature Storage

After cutting into squares, store this in an airtight container at room temperature for up to 2 weeks. I use glass containers with locking lids to keep air out. The flavors actually deepen slightly over the first few days. ❄️

Refrigerator Option

For longer freshness, refrigerate for up to 1 month in a sealed container. Let pieces sit at room temperature for 30 minutes before serving to restore that melt-away texture. Cold fudge loses some of its signature creaminess.

Freezing for Later

Wrap individual squares in parchment paper, then place in a freezer bag with layers separated by paper. This prevents sticking and allows grabbing just what you need. Freeze for up to 3 months without quality loss.

Thawing Method

Transfer frozen pieces to the refrigerator overnight, then let sit at room temperature for 1-2 hours before serving. For quick thawing, microwave at 30% power in 10-second intervals until soft. 💡

Reheating Tip

If your fudge dries out slightly, place pieces on a microwave-safe plate, cover with a damp paper towel, and heat for 5-8 seconds. This restores moisture and brings back that fresh-made consistency.
