My grandma made chocolate gravy all the time. I absolutely love it. All it is: 5 Tbsp unsalted butter, 3 Tbsp flour, 3 Tbsp cocoa powder, 4 Tbsp sugar, 1 cup milk, 1-1/2 tsp vanilla. Drizzle this velvety, sweet sauce over a hot buttered biscuit, angel food or pound cake or over a bowl of strawberries. Delicious!
