Apple crumble bars

I recently found a recipe for apple crumble bars which tempted me to make them. The apple is coated with a mix of cinnamon, nutmeg and ginger, then placed over half the crumble mixture and topped with the other half.  The addition of the spices gives a very autumnal flavour to the bar.  My first attempt was, ahem, rather a disaster, due to me thinking that I knew best on the quantities and ending up with a very soggy cake-type creation (although it did taste nice).  I had only said to Chris a few days previously that baking is the one thing where you have to stick to the recipe, so I have no-one to blame but myself.  However, not to be discouraged, I decided to have another go, this time following the recipe exactly.    It has turned out with more crunch to it, but I still feel that it will go soggy.  Perhaps this is something that needs to be eaten quickly - never a problem in our house!
