Preheat oven to 350.
Butter the ramekins well, and set aside.
In a small bowl mix all the dry spices.
In a medium bowl, mix apples, 1/4 cup brown sugar, 1/2 the spice mix, bourbon, vanilla and the lemon juice.
In a separate mixing bowl, add the oats, the rest of the spices, flour, and butter.
Cut the butter into the topping mix with a pastry cutter. Looking for a very coarse, pea-like texture here.
Fill each ramekin 3/4 full with apple filling, and top with the oat mixture.
Bake for 45-60 minutes until golden brown and bubbling.
Cool for 5 minutes, top with a scoop of vanilla ice cream, and serve.
