Forevermama's Heirloom Brownies

""These Brownies have basically become a part of my family. I've been making them since I was about 13 or 14. On one occasion when I was a teenager, I made them in a 9 x 13" pan and while they were cooling I went over a friends house on my street, when I came back about 45 minutes later, the only thing left in my pan were crumbs. My 3 bratty nephews gobbled it all up! Ohh the memories. They derive from a 1954 Sealtest cookbook called "641 Tested Recipes from the Sealtest Kitchens." The pages are yellowed, fraying and falling apart, but I love it so, especially because my sister Edna gave it to me and she has since passed away. These bake beautifully and create a chocolaty crust over the top and a chewy center. It is a basic recipe that surpasses in flavor many other "fancified" brownie recipes I have tried."..."
