Homemade Hot Fudge Sauce

"Homemade hot fudge sauce is SO much better than the kind you can buy at the store. This recipe originates from my Grandma. It's actually really easy and only has 5 ingredients. Ingredients include, baking chocolate, butter, sugar, evaporated milk, and vanilla. This hot fudge sauce is so good when it is still warm and drizzled over vanilla ice cream. If you've never tried a homemade chocolate sauce, now is the time! Your taste buds will thank me!"
