I have added the recipe for Brownie Swirl Cheesecake to my recipe blog as requested. I have to say it was a big hit. My husband usually shows great restraint when eating desserts but he finished off about a quarter of a 9 x 13" pan in one sitting!
I tried a little piece of it a few hours after baking and then again after it had sit in my (very) cold garage for about six or seven hours. The flavors were much better after it had been allowed to chill longer.
