These are my new go to brownie recipe! I haven't had much luck with homemade brownie recipes in the past, and one night the kids and I had a hankering for brownies, but didn't have any brownie mix. I came upon this recipe and had all the ingredients already, so we made these and they are DELICIOUS!!! Good tip about the baking soda by the way. Also, I seem to have the opposite problem, my brownies always are higher on the sides, and thinner in the middle. And I only left these in the oven for 30 minutes, then let them sit until cooled, since we like our brownies on the fudgier side. These are, by far, the BEST homemade brownies I've ever had!
