🛒 Ingredients You’ll Need

Sweetened Condensed milk, chocolate chips, and peanut butter on a counter.

This recipe showcases both chocolate and peanut butter. Sweetened condensed milk is the key ingredient that creates a creamy, stable fudge. You can customize the fudge by stirring in nuts, shredded coconut, dried fruit, or different types of chips like white chocolate or butterscotch. Smooth peanut butter yields a creamy texture; use chunky if you want extra crunch. Dark chocolate chips also work well if you prefer a richer taste.

🍫 Combining Peanut Butter and Chocolate

There are a few ways to layer or swirl the flavors. Melt chocolate with half the sweetened condensed milk, and melt peanut butter with the other half. For a layered look, pour one flavor first and the other on top. To create swirls, alternate scoops of each mixture and run a knife through to marble the top. Alternatively, melt both together for a single, uniform layer that blends the two flavors.

👩‍🍳 Using a Microwave to Make Fudge

The microwave speeds up prep—most of this recipe can be completed in under 10 minutes. If you don’t have a microwave, melt the mixtures in two small saucepans over low heat or use a double boiler to avoid scorching the chocolate.

📋 Step-by-Step Recipe Instructions

Step 1: Line an 8×8 inch pan with aluminum foil and spray with cooking spray.

Step 2: In a microwave-safe bowl, combine 1 cup peanut butter with half the sweetened condensed milk. Microwave for 1 minute 30 seconds, stirring every 30 seconds, until smooth. Set aside.

Step 3: In a separate microwave-safe bowl, combine the chocolate chips and the remaining sweetened condensed milk.

Step 4: Microwave the chocolate mixture for 1 minute, stirring at 30 seconds, until smooth. Set aside.

Important note: Both mixtures should be smooth but slightly thick. If they become grainy or too stiff, they were overheated—stir well and let cool slightly before using.

Step 5: Pour the chocolate into the prepared pan, then add the peanut butter mixture on top. Spread evenly and, if desired, run a knife through to create swirls.

Step 6: Cover with plastic wrap and refrigerate for at least 4 hours or overnight. Once set, cut into squares and serve.

🙋 Recipe FAQs

Do you heat the chocolate and milk or just stir them together?

Melt the chocolate chips with half the sweetened condensed milk—heat and stir until smooth. Melt the peanut butter separately with the remaining condensed milk.

Can this recipe be doubled and if so, what size pan should I use?

Yes. If doubling, use a 9×13 inch pan.

💭 Expert Tips

  • Use a sharp chef’s knife for clean slices. Warm the blade under hot water, dry it, and then cut.
  • Keep the fudge cold while slicing; it cuts more cleanly straight from the fridge.
  • Store fudge in an airtight container in the refrigerator. Separate layers with parchment or wax paper to prevent sticking.
  • Fudge keeps well refrigerated for 2–3 weeks.
