- ½ cup white sugar
- 3 tablespoons unsweetened cocoa powder
- ¼ cup cornstarch
- ⅛ teaspoon salt
- 2 ¾ cups milk
- 2 tablespoons butter, room temperature
- 1 teaspoon vanilla extract
Stir together sugar, cocoa, cornstarch, and salt in a saucepan. Place over medium heat, and stir in milk. Bring to a boil, and cook, stirring constantly, until the mixture thickens enough to coat the back of a metal spoon. Remove from heat, and stir in butter and vanilla.
