Hey,
Made it again for another birthday party. All the non-gluten free eaters helped polish it off in no time.

Just wanted to update that I made it with the 365 brand mix I recently discovered at Whole Foods (made with guar gum instead of xanthan gum.)
Turned out just as great as with my homemade flour mixes. I also made it with honey and brown sugar rather than white sugar. I just used 1/4 cup less in the mix. Cake was much moister with the honey. I actually liked it better.... Either way it is good though.
Just an FYI for anyone looking for a quick shortcut.
I'm thinking this is going to be 'THE' cake for birthdays and holidays as it is starting to get regular requests. LOL. Hubby especially likes it.
