🛒 Ingredients You’ll Need

This condensed milk-based fudge is smooth and holds together beautifully. Sweetened condensed milk is the key to the creamy texture. You can customize the recipe by folding in nuts, coconut, white chocolate chips, dried fruit, or even leftover candy. Smooth peanut butter keeps the texture silky, while chunky peanut butter adds bite. Use any chocolate chips you prefer, including dark chocolate for a richer flavor.
🍫 Combining Peanut Butter and Chocolate
For this recipe, melt the chocolate chips with half the sweetened condensed milk and melt the peanut butter with the remaining condensed milk in a separate bowl. You can layer the two mixtures for a distinct two-tone fudge, pour a solid chocolate base then swirl the peanut butter on top, or melt everything together for a uniform flavor. Swirling creates attractive marbling and a contrast in texture.



👩🍳 Using a Microwave to Make Fudge
The microwave makes this recipe exceptionally fast—most of the prep takes under 10 minutes. If you prefer not to use a microwave, melt the mixtures gently on the stovetop in separate saucepans or use a double boiler for the chocolate to avoid scorching. Microwaves vary in power, so watch closely and stir frequently.
📋 Step-by-Step Recipe Instructions
Step 1: Line an 8×8 inch pan with aluminum foil and lightly spray the foil with cooking spray.
Step 2: In a microwave-safe bowl, combine 1 cup peanut butter with half (about 7 ounces) of the sweetened condensed milk. Microwave for 1 minute 30 seconds, stirring every 30 seconds, until smooth. Set aside.
Step 3: In a second microwave-safe bowl, combine a 12-ounce bag of chocolate chips with the remaining sweetened condensed milk.
Step 4: Microwave the chocolate mixture for 1 minute, stirring at 30 seconds, until smooth. If you don’t have a microwave, melt gently on the stovetop or in a double boiler.
👩🍳 Important Note: Both mixtures should be smooth but slightly thick and easy to stir. If either becomes very hard to stir, it was heated too long—warm gently to loosen.

Step 5: Pour the melted chocolate into the prepared pan. Spoon or pour the peanut butter mixture on top. Smooth and use a knife sprayed with cooking spray to swirl the layers for a marbled effect.
Step 6: Cover with plastic wrap and refrigerate for at least 4 hours or overnight. Once firm, cut into squares and serve.
