In a large bowl , whisk the eggs
Add the sugars, coffee and vanilla
Whisk well until sugar dissolves
Add the melted chocolate
Now add the flour and salt
Mix well ( no lumps)
Pour batter in a lined 8’’x8’’ baking dish (I used a 9’’ x 9’’ instead hence got a slightly thinner brownie )
Bake at 350F for 25 to 30 mins
