Homemade Hot Fudge Sauce

1. In a medium saucepan, over medium heat, heat milk, chocolate chips, and sugar until boiling, stirring constantly.
2. Remove from heat, and stir in butter and vanilla until blended.
3. Serve warm, or transfer to a storage container to cool completely.
4. Cover and refrigerate.
5. To serve, uncover sauce and reheat in the microwave for 30–60 seconds on high, or until warm and pourable.
6. Serve over ice cream, brownies, cheesecake, chocolate sheet cake. Or eat with a spoon right out of the fridge. (I’m only kidding. Kind of.)

Variation: For a Mayan-style fudge sauce, stir in 1/8 teaspoon ground cinnamon, and a hefty pinch of chipotle chili powder. Seriously good stuff.
