1. Line an 8×8 inch baking pan with parchment paper, leaving plenty of overhang on two opposite sides to create handles for easy removal later. This step is crucial—don’t skip it or you’ll struggle to cut neat squares.
2. In a large microwave-safe bowl, combine the chocolate chips, sweetened condensed milk, and butter. Microwave on high power for 30 seconds, then remove and stir thoroughly. Repeat this process—30 seconds, stir, 30 seconds, stir—until everything is completely melted and smooth. This usually takes 2-3 minutes total. Don’t rush by using longer intervals or the chocolate might seize.
3. Once everything’s melted and smooth, stir in the vanilla extract and salt until well combined. The mixture should be glossy, uniform, and smell amazing.
4. If using nuts, fold them in now, distributing them evenly throughout the fudge mixture. Make sure they’re incorporated but don’t overmix.
5. Pour the fudge mixture into your prepared pan and spread it out evenly with a spatula. The mixture will be thick and glossy. Smooth the top so it’s level.
6. Refrigerate the fudge for at least 2 hours, or until completely set and firm to the touch. Be patient—it needs time to firm up properly.
7. Once set, use the parchment paper handles to lift the entire fudge slab out of the pan and place it on a cutting board. Cut into small squares using a sharp knife—a 6×6 grid gives you 36 perfect pieces.
8. Store in an airtight container in the refrigerator for up to 2 weeks, or freeze for up to 3 months. Let it sit at room temperature for a few minutes before serving if you prefer softer texture.

What Makes This Recipe Special:

Fudge became an American confection staple in the late 1800s, with early recipes requiring careful sugar cooking that made it notoriously tricky. What distinguishes this modern easy fudge from traditional versions is using sweetened condensed milk instead of cooking granulated sugar to precise temperatures—a game-changing mid-20th century technique that made perfect fudge accessible to everyone. The simple method of melting chocolate with condensed milk and butter eliminates all the temperature anxiety and crystallization problems that plagued traditional recipes, representing the evolution of candy-making from difficult craft to easy home treat anyone can master.
