The peanut butter is the foundation here. Jif or Skippy work great, but natural brands (the kind where oil separates) can make your fudge greasy. I always grab mine from Costco—giant jar, lasts forever. For the condensed milk, Eagle Brand is the gold standard. Check the label to avoid the fat-free version—it won’t set properly.

No chocolate chips? Chopped chocolate bars melt even better. Swap semi-sweet for milk chocolate if you want it sweeter. Skipping the nuts? No problem—dried cranberries or shredded coconut add a nice twist. The vanilla can be swapped for almond extract (use half the amount), which gives a marzipan-like note.

This keeps 2 weeks at room temp in an airtight container. Freeze for 3 months if you somehow have leftovers. Cut into small squares (don’t skip the parchment paper) so it’s easy to grab a piece whenever the craving hits.

Step-by-Step Instructions for Fudge Recipe Peanut Butter Condensed Milk

Here’s the method—simple, foolproof, and guaranteed to impress every time.

Step 1: Melt the Chocolate Base

In a medium saucepan, combine the 2 cups Semi-Sweet Chocolate Chips, 1.5 cups Creamy Peanut Butter, 1 can Sweetened Condensed Milk, and 2 tbsp Unsalted Butter. Place it over low heat—this is crucial to prevent scorching.

Stir constantly with a silicone spatula as the mixture melts. You’ll notice it transforms from solid chunks to a glossy, smooth liquid in about 5-7 minutes. Remove from heat as soon as everything is fully melted and combined. The mixture should be thick but pourable, with no visible lumps.

Step 2: Incorporate Flavor Enhancers

Off the heat, stir in the 1 tsp Vanilla Extract and 0.25 tsp Sea Salt. The vanilla adds depth, while the salt balances the sweetness beautifully. I always use pure extract here—imitation just doesn’t deliver the same warmth.

If you’re using the optional 2 tbsp Cocoa Powder, whisk it in now until fully dissolved. This step deepens the chocolate flavor and gives the fudge a richer color. The mixture will thicken slightly as the cocoa incorporates.

Step 3: Fold in Extras for Texture

Now for the fun part: gently fold in the 0.5 cup Chopped Nuts and 1 cup Marshmallow Fluff. The nuts add a satisfying crunch, while the fluff lightens the texture and adds a playful marshmallow swirl.

Use a spatula to distribute these additions evenly throughout the mixture. Be careful not to overmix—the fluff should create visible ribbons rather than fully blending in. The fudge will be thick and slightly sticky at this stage.

Step 4: Set and Finish

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

Let it set at room temperature for 2-3 hours, or refrigerate for 1 hour if you’re impatient. Once firm, use the parchment overhang to lift the fudge out, then cut into squares. For a finishing touch, dust with 0.5 cup Powdered Sugar before serving.

Storing and Reheating fudge recipe peanut butter condensed milk

Room Temperature Storage

Store your fudge in an airtight container at room temperature, layered between sheets of parchment paper to prevent sticking. It stays fresh for up to 2 weeks, though I doubt it’ll last that long. Keep it in a cool, dry place away from direct sunlight. 💛

Refrigerator Storage

For longer freshness, refrigerate in an airtight container for up to 1 month. The texture may firm up slightly, but it softens quickly at room temperature. Let it sit for 30 minutes before serving to restore that perfect melt-in-your-mouth consistency.

Freezing for Later

To freeze, wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag or container. This keeps for up to 3 months. I like to freeze in small batches so I can thaw only what I need.

Thawing Instructions

Thaw frozen fudge in the refrigerator overnight or at room temperature for 2-3 hours. Avoid microwaving, as it can cause uneven heating and a grainy texture. Once thawed, let it sit briefly to return to its creamy best.

Serving After Storage

If your fudge has dried out slightly, place it in a container with a slice of bread for 24 hours—the bread’s moisture will revive it. For a fresh finish, dust with a little powdered sugar before serving. ✨
