Base:

4 cups of the fruit of your choice: berries, peaches, cherries, rhubarb, apple, or any combination

1/4 cup brown sugar (you may want more with rhubarb)

1/4 cup flour (to thicken the juices from the fruit)

(you may want to add cinnamon if you are using apples)

Topping:

1/2 cup melted butter

1 cup flour

1 cup brown sugar

1 cup oatmeal

Preheat the over to 325F.  In a bowl combine the fruit with the sugar and flour.  Mix to coat well.  Pour into a 9X9 glass cake pan and press the fruit in snugly.  Combine the ingredients for the topping in a separate bowl.  The mixture should be able to press into a ball and hold its shape – if not, add a little more butter.  Pour the topping over top of the fruit and press firmly and evenly to make a smooth topping.  Bake for 30-45 minutes or until the fruit is bubbling up through the topping (time will vary depending on the fruit).  Let it cool and enjoy!
