Peanut Butter Fudge Recipe Using Evaporated Milk: Ultra Creamy No-Bake Squares

This no-bake fudge delivers ultra-creamy results with minimal effort and maximum flavor.

I developed this method after years of testing, and the evaporated milk creates a velvety texture that melts in your mouth. The process requires just a saucepan and patience as the mixture thickens to perfection.

What emerges is rich peanut butter fudge with a smooth, luxurious consistency that rivals any candy shop version. The evaporated milk ensures it stays soft and creamy, never grainy or crumbly.

Perfect for gifting or satisfying sweet cravings, this recipe proves that the best treats often require the least amount of oven time.

Ingredients for Peanut Butter Fudge Recipe Using Evaporated Milk

Just seven ingredients for ultra-creamy no-bake peanut butter fudge that melts in your mouth.

The evaporated milk is non-negotiable for that velvety texture—Carnation is the most reliable brand at any grocery store. Creamy peanut butter (Jif or Skippy) works better than natural here since it blends smoothly without separating. Unsalted butter lets you control the salt level, and Land O’Lakes is a safe bet. Don’t skimp on the vanilla; pure extract makes a noticeable difference in flavor depth.

No evaporated milk? Sweetened condensed milk changes the texture but works in a pinch—just reduce sugar by half. Natural peanut butter can substitute, but stir it well first (or the oil will separate). Marshmallow creme instead of fluff is identical—just a different brand name. For a lighter version, reduced-fat evaporated milk works but may yield slightly less creamy results.

Store fudge in an airtight container at room temperature for up to 1 week, or refrigerate for 2 weeks. Freezing is possible for 3 months, but thaw slowly to prevent condensation. Cut into squares only after fully set to avoid crumbling.

Step-by-Step Instructions for Peanut Butter Fudge Using Evaporated Milk

This no-bake method delivers perfectly creamy, melt-in-your-mouth fudge with minimal effort.

Step 1: Combine and Boil the Sugar Mixture

In a 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 heat and stir constantly until the butter melts and the sugar begins to dissolve.

Once boiling, stop stirring and let the mixture reach a full rolling boil. Continue boiling for 4-5 minutes, undisturbed, until it reaches the soft-ball stage (234-240°F on a candy thermometer). Watch for the mixture to thicken slightly and turn a light caramel color.

Step 2: Incorporate Peanut Butter and Fluff

Remove the saucepan from heat and immediately stir in the 1 cup Creamy Peanut Butter and 1 jar Marshmallow Fluff. The peanut butter will begin to melt into the hot sugar mixture, creating a smooth, glossy base.

Use a wooden spoon or silicone spatula to fold the ingredients together until fully combined. The mixture will be thick and slightly sticky. This step ensures the fudge has that signature creamy texture and rich peanut butter flavor.

Step 3: Add Vanilla and Salt for Depth

Stir in the 1 tsp Vanilla Extract and 0.25 tsp Salt until evenly distributed. The vanilla adds warmth and balances the sweetness, while the salt enhances the peanut butter flavor.

At this point, the mixture should be thick, smooth, and pulling away slightly from the sides of the pan. If it seems too thin, let it sit for 1-2 minutes to cool and thicken slightly before proceeding.

Step 4: Pour, Set, and Cut into Squares

Line an 8×8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Pour the fudge mixture into the pan and spread it evenly with a spatula. The top should be smooth and glossy.

Let the fudge cool at room temperature for 1-2 hours until fully set. For faster results, refrigerate for 30-45 minutes. Once firm, use the parchment overhang to lift the fudge out of the pan and cut into 16 equal squares.

Make-Ahead Tips for This peanut butter fudge recipe using evaporated milk

Prep Ahead Strategy

You can prep all dry ingredients the night before. Measure out the 3 cups Granulated Sugar, 1 cup Creamy Peanut Butter, and ¼ tsp Salt and store in separate containers. This saves 10 minutes on cooking day. 💡

Early Mixture Prep

Combine the sugar, evaporated milk, and butter in your saucepan ahead of time. Cover and refrigerate for up to 8 hours. Just warm slightly before starting to help the butter melt faster.

Pan Preparation

Line your 8×8-inch baking pan with parchment paper up to 24 hours in advance. I keep pre-cut parchment sheets ready to go. This ensures you can pour the hot mixture immediately without scrambling for supplies.

Make in Batches

Double the recipe and make two batches at once. The mixture keeps its texture beautifully when prepared simultaneously. Store one batch in the fridge for up to 2 weeks while gifting the other. 💛

Quick Setting Tip

If you’re short on time, spread the mixture in a shallow, wide container like a rimmed baking sheet. It’ll set in the fridge in just 20 minutes instead of 1-2 hours at room temperature.

Portion Control

For easy serving later, cut the fudge into squares immediately after setting but before it fully firms. Wrap individual pieces in wax paper and store in an airtight container for grab-and-go treats.
