Yankee Apple Crisp - cooking recipe

Ingredients

6 -8 granny smith apples (see note)
1/3 - 1/2 cup butter, melted, I use 1/2
3/4 cup brown sugar, packed
1/2 cup flour (see note)
3/4 cup rolled oats
1 -2 teaspoon cinnamon
3/4 teaspoon nutmeg
1/2 cup walnuts, coarsely chopped (optional)

Preparation

Preheat Oven to 375 degrees.Lightly grease or spray a 9x13 pan (pyrex is good) or any other 2 qt baking dish.
Melt butter in medium pot or bowl, remove from stove or microwave and stir in oats, brown sugar, flour, spices and nuts if using.
Peel, core and slice apples (thin or a little thicker - I use my corer/peeler/slicer which makes them pretty thin), then place in pan - I like to sprinkle the apples with a little cinnamon.
Sprinkle crumbs over tops of apples covering as much as possible but a few gaps are ok.
Bake for 45 minutes, if crumbs start to get too brown before the apples are done, you can float a piece of foil loosely over the top. Apples should be very soft when poked with a thin knife.
Serve warm or at room temperature, wonderful with fresh whipped cream or vanilla ice cream.
NOTES:
You can use other apples, Granny Smiths are pretty tart but that makes a nice contrast with the sweet topping. You can add a couple of teaspoons of sugar if you think they might be too tart for you or use a combo of apples - you can use your favorites, but avoid ones the go to total mush when baked.
I often stir 2-3 tsp of flour into to the apples to avoid watery juice in the bottom of the pan after baking.
I like to use whole wheat pastry flour (not regular whole wheat) for added flavor and nutrition, or a little wheat germ in with the white flour is good too.
You can use this for other fruits also - sometimes I add in some frozen raspberries or sub peaches for the apples, they like blueberries and raspberries too. Peaches will probably need the extra sugar and flour added to them and a little ground ginger and/or cloves added to the topping is delish!
