i've made this recipe SO many times... everyone expects me to make it.. if i dont, i hear about it! ...the first time i made it, i didnt like using the foil. when i bake, i only use the "air-bake" pans.. which are a must in my opinion. i've never had a problem getting the cheesecake out. ..brownie mix that has worked the best for me is the moist pillsbury family size 9x13, (blue box). a must try!
