Cinnamon Roll Cake

So, I'm browsing around pinterest like any other typical day and I run across this picture of heaven. Thanks to my daughter, I had everything for this except for eggs. She's such an egghead :)
So, to the neighbors house I send the kid for eggs. Boy oh boy was I thrilled to know she had a couple of extra eggs. Glad I didn't tell what I was cooking or I would have (like always) said I'd share when done. After taking the first bite, it was not likely that I'd be sharing with anyone. I plan to make one for them one day and just show up baring this heavenly gift!
So, when I follow the link I end up here. Everyone take a little bit to check out her stuff. It's wonderful!
Here's the ingredients for this heavenly cloud of a thing called Cinnamon Roll Cake
