TWD-Shrinking Dimply Plum Cake

I know, the name of this week's treat for TWD is simply Dimply Plum Cake. However, I found it appropriate to add shrinking to the title as each time I walk through the kitchen, the cake seems to get slightly smaller. I know, weird. I bought some plums at the Thursday farmers' market and evidently the fruit they grow around here is mutant. No, not like fish from the Simpson's with three eyes, its just twice as large as normal. I cut the plums into fourths and only ended up using two. If I had used four halved plums, they wouldn't have all fit in my 8x8. Yeah, they're huge, but red and juicy and sweet and contrast nicely with the crumbly brown sugar cake. I'd definitely make it again with whatever stone fruit I have on hand, as the batter comes together quickly and without fuss. The cake does not, however, have a very long shelf life, so I figure its probably best for this cake, and all involved, that its been quickly disappearing.
