Jackie's Famous Apple Crisp

This recipe varies every time since I never really measured ingredients, but it's delicious and is everyone's favorite.
Serves 6

Ingredients
6 granny smith apples
2 sticks of butter
1 cup brown sugar
1 cup white sugar
1/2 cup flour
salt
2 tbls vanilla extract
2 eggs
4 tbls lemon juice
3/4 cup oats

Directions:
Preheat oven to 350 degrees.
Peel, pit, and cut apples into small wedges. Place apples aside in a bowl with the lemon juice.
In a skillet, melt the butter and add brown sugar and white sugar. Once ingredients have turned to a liquid, mix in vanilla extract and dash of salt. When combined, place into a bowl and mix in the flour, eggs, and oats. Mixture should be like a heavy liquid paste (if not, add ingredients to reach right consistency.) Once the paste mixture is ready, lay the apples in a casserole dish or rectangle glass dish, so that the apples cover the bottom. Pour mixture over the apples. If you have any extra oats, you can sprinkle some on top. Place into oven and bake for 30-40 minutes, or until top has a browned crispy look.
