"These are VERY yummy! EXCEPT, I melted the butter before I mixed it with the brown sugar; I halved the recipe (since I was only making it for two people), and since it calls for 3 eggs, I put one egg and one egg yolk; also, I skipped the baking soda and baking powder to render a more dense, chewy blondie. I might've overcooked it by a few minutes cause the edges were tough, I should've cooked it for about 23-25 minutes.. otherwise, these were great!
