Plum Buckle ... Buckle what?

This is a gem my mom found years ago, the perfect reason to keep a plum tree in your garden.

Fruit desserts are more than just pies. While pie crust is a lot of work, upside-down cakes, cobblers, crumbles, crisps and buckles are easier and just as delicious in my book. From what I've read, it seems like the differences between these names for baked fruit desserts are nearly as much regional as they are descriptive.

What's a buckle? Based on this dessert, I like to think a buckle is an upside down cobbler, where the cake "buckles" under the weight of the fruit. 

Serve it warm with ice cream, or just eat it for breakfast, this is fruit and cake.
