Recipe: Single serve apple crumble

I had a few comments intrigued about a Facebook picture I put up last night of my dessert that I cooked up from an idea that I blatantly stole from MasterChef New Zealand.
Specifically, what the thing on the left is. The short answer is, an apple crumble.

It's a pretty terrible picture really.

Now, you probably have your own various fruit crumble recipes but this is the recipe I more or less used. If you think things can be done better, let me know, I might try it out or I might just change what I've written here. It's all a little sketchy because I was kinda making it up as I went along, but oh well, here goes!

This recipe is just for a single serve. Increase the recipe depending on how many people you want to serve and tada!
