Ingredients
2 cups granulated sugar
1 (14-ounce) can evaporated milk (1 1/2 cups)
8 ounces unsweetened chocolate, melted and cooled
Preparation
Place sugar, evaporated milk, and melted chocolate in a blender; blend until smooth and thickened, about 1 minute (the blender’s sound will change when the frosting reaches the right consistency.)
Transfer frosting to an airtight container; let stand at room temperature until slightly thickened and spreadable, about 1 hour. Store in an airtight container and refrigerate up to 3 days (bring to room temperature before using).
