Another great recipe, Sharon! We thought this cake was fantastic. I didn't have any sour cream on-hand, so I replaced it with yogurt. Even with this substitution, the cake is very rich (which is a good thing, in my opinion). I picked this recipe in order to use up some egg yolks, but I'll be making it when I don't have any extra yolks sitting around, too. Thanks!
I am re-reviewing this because I did not serve it warm the first time. This is a very good coffee cake. DH and I both enjoyed it. The topping is OH SO GOOD! It is okay cold, but warm is YUMM-MY! Thank you Sharon.
