This foolproof, no-fuss, classic fudge recipe is a family favorite! You only need a few ingredients to make this rich, decadent fudge! We make it every holiday season, but it can be enjoyed anytime!
Line a 8-inch square baking dish with parchment paper or aluminum foil, leaving about a 1-inch overhang for easy removal. Gently spray with nonstick cooking spray and dab away any excess oil with a paper towel. Set aside.
In a large, heatproof bowl, combine the chocolate chips and butter. Set the bowl over a pan of simmering water over medium-low heat, making sure the water never touches the bottom of the bowl. Use a spatula to stir until completely melted and combined.
Add the sweetened condensed milk, sea salt, and vanilla extract. Stir until well combined and smooth. Add the nuts, if using, and stir again.
Pour into the prepared pan and spread the top with a spatula until smooth.
Refrigerate until set, about 2 to 3 hours.
Carefully lift the fudge out of the pan and cut into small squares.
Notes
Store in an airtight container on the counter for up to 2 weeks or you can store in the refrigerator for up to 1 month. You can also freeze fudge. Wrap it in foil and place in a freezer container or bag. Freeze for up to 2 months.
