Ingredients for Peanut Butter Fudge Recipe Ingredients

Simple pantry staples transform into a luxurious treat with minimal effort and maximum reward.

The peanut butter is critical—Jif or Skippy work perfectly, but natural peanut butter often separates and can affect texture. Evaporated milk (not sweetened condensed) provides the silky base. For best results, use name-brand butter like Land O’Lakes; generic brands can have higher water content, which may cause graininess. All ingredients should be at room temperature before starting.

Need a substitution? Sweetened condensed milk can replace evaporated milk in a pinch (reduce sugar by half a cup). Marshallows can stand in for the fluff at 10 large or 1 cup mini. For a nut-free version, sunflower seed butter works, though the flavor differs. The chocolate chips are optional but add depth—Guittard or Ghirardelli melt beautifully.

Store in an airtight container at room temperature for up to 1 week, or refrigerate for 2 weeks. For longer storage, freeze for up to 3 months. Slice before freezing for easy portioning. Always bring to room temperature before serving for optimal texture.

Step-by-Step Instructions for Peanut Butter Fudge

Master this technique for a velvety smooth texture that melts in your mouth.

Step 1: Combine Sugar, Evaporated Milk, and Butter

In a heavy-bottomed saucepan, combine the 3 cups granulated sugar, 0.66 cup evaporated milk, and 0.5 cup unsalted butter cut into small pieces. Use medium heat and stir constantly to prevent scorching as the mixture comes to a boil.

Continue boiling for 4-5 minutes until the mixture reaches 234-240°F on a candy thermometer. This is the soft-ball stage, crucial for achieving that signature fudge consistency. The mixture should form a ball when dropped into cold water.

Step 2: Incorporate Peanut Butter and Marshmallow Fluff

Remove the saucepan from heat immediately once the temperature is reached. Stir in the 1.5 cups creamy peanut butter and 1 cup marshmallow fluff until completely smooth. The residual heat will melt the additions evenly.

Add the 1 tsp vanilla extract and 0.25 tsp salt, stirring vigorously to distribute evenly. This step transforms the mixture from a sugar syrup into a rich, velvety base for your fudge. Work quickly to prevent the mixture from setting prematurely.

Step 3: Fold in Optional Additions and Set

If using, fold in the 1 cup semi-sweet chocolate chips until just combined. The heat of the mixture will soften them slightly, creating a marbled effect throughout the fudge. For a classic peanut butter flavor, you can omit this step entirely.

Immediately pour the mixture into a greased 8×8-inch baking dish or line the dish with parchment paper for easy removal. Use a spatula to smooth the top evenly. The mixture will begin to set within 5 minutes, so work efficiently.

Step 4: Chill and Slice for Serving

Let the fudge cool at room temperature for 10 minutes, then sprinkle the 0.5 cup chopped peanuts evenly over the top, pressing lightly to adhere. This adds a delightful crunch and visual appeal to each piece.

Refrigerate for at least 2 hours or until completely firm. Once set, remove from the dish and cut into 1-inch squares using a sharp knife. For clean cuts, dip the knife in hot water between slices. Store in an airtight container at room temperature for up to a week.

Creative Variations of peanut butter fudge recipe ingredients

Chocolate Swirl

For a marbled effect, melt 1 cup semi-sweet chocolate chips separately with 1 tbsp butter. Pour the peanut butter mixture into your dish, then drizzle the melted chocolate over the top. Use a butter knife to gently swirl the two together before chilling. 🔥

Crunchy Peanut

Press ½ cup chopped peanuts into the top of the fudge before it fully sets. For extra texture, reserve ¼ cup to mix directly into the batter during the final stirring step. The contrast of creamy and crunchy is irresistible.

Salted Caramel

Stir ½ cup store-bought caramel sauce into the mixture along with the peanut butter. Finish with a sprinkle of flaky sea salt like Maldon. The sweet-salty combination elevates the classic peanut butter flavor beautifully.

White Chocolate

Replace semi-sweet chips with 1 cup white chocolate chips for a sweeter, creamier version. I recommend Ghirardelli for the smoothest melt. Add ½ tsp almond extract alongside the vanilla for a subtle nutty depth.

Coconut Dream

Fold in ½ cup toasted coconut flakes at the end for a tropical twist. Press additional coconut on top before chilling. This variation pairs wonderfully with the creamy peanut butter base.

I love how this adds an unexpected texture that surprises everyone. ✨
