In a large sauce pot, add in chocolate chips, condensed milk, butter, and peppermint extract.
Over low heat, stir constantly until combined. Be sure to scrape the bottom of the pan to avoid any chocolate burning.
Pour mixture into a 8-inch x 8-inch pan and even out the top. (11x7 or 9x13 will work as well, though a larger pan will yield a thinner batch of fudge.
If you're putting crushed candy canes on, let cool for 10 minutes and sprinkle on top.
Cool in the refrigerator for 2-3 hours before cutting. Cut into 1 inch pieces and serve!
Notes
Microwave – Easy, but temperamental with the chocolate and condensed milk. Great if you’re short on time. Put all the ingredients in a large bowl and zap it 30 seconds at a time until everything is combined.
Stovetop with sauce pot- Again, easy. I just use a sauce pot and consistently stir the mixture to make sure nothing gets stuck on the bottom. Be sure to keep watching and stirring!
Stovetop with double boiler – Also easy, but I know not everyone has a double boiler. You can stick a glass bowl on top of a sauce pot with simmering water over it to give you the double boiler effect. It’s more consistent for the chocolate and lessens your chance for having your chocolate burn!
