My family loves Jello cake, so I made a grown-up variation for my mom's birthday. It's yellow cake layered with strawberries and frosting made from pudding, cream cheese, and whipped cream. So good, if I do say so myself!
If I had it to do over again, I'd have split the layers in half and put berries and filling between them, too. And I'd have centered the top layer better, because even though you can't tell it from the picture, we had a Leaning Tower of Cake-a going on. Somehow it still was eaten, though! :)
