Stuff It!!!!

This is the famed churpumple!  It is a combination of pies and cakes.  They bake a pie, then put it in a cake and bake that, repeat 2 more times then go nuts with icing.  The peanut butter cup cake I made last month had a cheesecake sandwiched between two cakes, but it wasn't baked into the thing.  So what I want to know is when the hell did we start stuffing pies into cakes?????

And now that the door has been opened, what else are we going to be putting inside cakes in the days to come?

Let me know your ideas, what have you always wanted to find inside a slice of cake?  Give me some good ideas and I will see how it goes....
