Great cake, but I'm sure it'd be even better if I hadn't been a total moron and forgot to add the cinnamon to the streusel mixture until I was starting to sprinkle on the second half of it ! DUH! So I quick added about a tablespoon to the remaining mix. ( I DID remember to add the half cup of chopped pecans that I wanted in it though) Tasted it a bit ago when it was still warm, and it's still very tasty. ( I still can't believe I did that...) I'm sure I'll be making this again - with all the cinnamon! Thanks.
