Chocolate gravy, made from cocoa powder, butter, milk, and vanilla extract, is the kind of dessert children love: creamy, sweet, and rich.
In a saucepan, combine cocoa powder, sugar, and flour.
Slowly stir in 1/2 cup milk.
Add remaining milk and stir.
Cook for 3 to 5 minutes at medium heat until thick.
Add vanilla extract and butter after turning the heat off.
