Flourless chocolate cake

I made this cake last night for our family dinner.  Oh. my. yumminess.  There is only one little piece left that I'm saving for Josh to have tomorrow after he eats lunch.  I altered the recipe a bit by using dairy free margarine in the cake.  For the salted caramel sauce I used margarine and Silk dairy free creamer.  I also used dark baking chocolate for half of what it called for, and I accidentally used 1 cup of brown sugar in the cake instead of the called for 1/4 cup.  Oops.  It worked though, probably because the chocolate was darker than what was called for.  The called for time for baking was 90 minutes, but I had to leave the house with about 10 minutes of baking left, so I turned off the oven and left it in to finish baking while the oven cooled down.  I turned it off at about 1:30 and came back to the house to get it at 5.  I was SO nervous that it would either be burnt or underdone, but it was actually perfect!  Now I just have to figure out if I do that again or try baking it the full 90 minutes.  I will definitely be making this again!
