The recipe also called for raisins, which I didn't have on hand, so I just left those out. I also couldn't find any unsweetened applesauce (is that the sort of thing you can't buy in stores and have to make yourself?), so I used Safeway's Chunky Original. I heaped the amount of both the yogurt and the applesauce, and the cake came out very moist.
Using the chunky applesauce worked great - the cake didn't have strong apple flavor at all, so the chunks gave it a little extra dimension. I did feel, though, that the clove taste was a little too strong. The next time I make it, I'll try halving it to let the other flavors come out more.
As you can see, I tried one in a square pan and a round one (both 8"), and topping them both with glaze.
I'm always collecting recipes from friends, but I don't often make the time to try them out - something I hope to remedy this summer. How often do you try new recipes?
