Combine butter, sugar and water in a small saucepan. Heat on medium and stir until sugar is melted. Remove from heat.
Add vanilla, eggs and 1 cup of chocolate morsels (I use Ghirardelli's) and stir until chocolate is melted.
In a medium sized bowl, combine baking soda, salt and flour, mix well. Add warm chocolate mixture and stir gently until combined.
Spray bottom of a 9"x13" baking pan with spray release of choice, then pour in the brownie batter. Wait a minute or two for the batter to even out over the pan, then sprinkle with the additional cup of chocolate morsels.
