Grease and flour (I like to use cocoa powder instead of flour) a 9x13 pan and set aside
In a microwave safe dish combine butter, cocoa powder and sugar.
Microwave in one minute increments, stirring after each minute, until butter is melted and cocoa and sugar are incorporated nicely.(see picture) In my microwave it takes three one minute increments to get the right consistency.
Transfer cocoa mixture to mixing bowl add salt and vanilla then and add eggs one at a time and mix until they are well combined.
Add flour and mix until combined.
Spread mixture evenly in the prepared 9x13 pan,
Bake at 350 for 30-35 minutes or until toothpick comes out clean
