Line a 8x8 baking dish with aluminum foil and spray with cooking spray. Set aside.
In a medium saucepan over low heat, mix the chocolate chips and sweetened condensed milk together until melted and smooth.
Pour the fudge mixture into the baking dish and spread out into an even layer. Sprinkle of the crushed peppermint and top the fudge.
Place in the refrigerator for 2-3 hours until the fudge has set.
Cut into small squares and enjoy.
Notes
If you like peppermint flavor, add in ½ tsp of peppermint extract with the chocolate chips and sweetened condensed milk for added peppermint flavor!Don't use high heat when melting or the chocolate will burn.Since the 3-ingredient fudge stores so well, it makes a great homemade gift.
