Brownie Frosting

Our favourite brownie frosting..

In a saucepan over med heat combine butter , sugar , milk , and cocoa.

Melt , and bring to a boil.

When it has bubbles all the way across the top of surface now time.

Boil hard one minute only.

Remove from heat , add vanilla.

Let cool slightly , stir and beat until its like very thick corn syrup , and sticky to bottom of pot.

I always use a spoon , so i can tell how it is thickening up.

Pour over brownies or cake.

granulated sugar, cocoa powder, milk, butter, vanilla
