Set oven at 375ºF. Toss peeled apples in 2 tablespoons of sugar, 2 tablespoons of flour, vanilla and bourbon and place in a skillet or pie dish.

Using your fingers mix together remaining sugar and flour with the butter and oats and sprinkle on top of the apples. Depending on the size of your pan you may be able to cover all the apples or not; it’s up to you.

Place in the oven and cook until crumble is brown and apples are soft, about 45 minutes. Serve warm with whipped cream or ice cream.
