Look no further than this recipe for the EASIEST and most FOOLPROOF fudge that takes less than 3 minutes to make!! Customize it with your favorite add-ins like cranberries and walnuts!
Line an 8×8-inch pan with foil or parchment for easier cleanup; set aside.
To a large, microwave-safe bowl, add the chocolate chips, sweetened condensed milk, butter, and heat on high power to melt, about 2 1/2 minutes but all microwaves vary in intensity. Stop to check and stir after 2 minutes and heat from there in 30-second intervals, if necessary, until the mixture can be stirred smooth.
Add the walnuts, cranberries, and stir to combine.
Turn mixture out into prepared pan, smoothing the top lightly with a spatula as necessary. Place on the counter to cool and set up fully, about 4 hours. If you are in a hurry, you can place the pan in the fridge to expedite it.
Slice and serve after fudge has set up.
Notes
Fudge will keep airtight at room temp for up to 1 month or in the fridge for at least 3 months. It is stable at room temp but if you prefer it firmer or live in a warmer climate, I recommend the fridge.
