Line the base of a 10 inch springform cake tin with parchment paper and grease the sides with some butter
With the "S" blade attachment on your food processor or in your blender grind up the oats.
Peal, cut and core the apples. With the shredding attachment in place on your food processor, put apples through to shred. If you do not have a food processor you can also shred apple with a cheese grater, however this will take a little longer.

In a separate bowl cream brown sugar and butter until fluffy. Then whisk in eggs, one at a time until combined. Next whisk in milk and vanilla.
Add dry ingredients to wet ingredients. Then gently fold in shredded apples until evenly combined.
