In a small sauce pan melt butter over medium heat until it is mostly melted - reduce heat to simmer and add chocolate morsels, stir untill melted - remove from heat and allow to stand two minutes to cool.
Stir in sugar until blended well.
Add eggs and vanilla mixing only until combined. Don not over mix or brownies will fall flat.
