Whole Wheat Chocolate Chip Cookies

This recipe came from a lady in my ward. They are always a big hit with my friends from that ward. It makes a lot of cookies so I usually half the recipe.

4 sticks of butter
2 cups brown sugar
2 cups white sugar
4 eggs

Beat the above together.

Add:
2 teasppons baking soda
2 teaspoons baking powder
1 teaspoon salt
2 teaspoons vanilla
4 cups whole wheat flour
2 cups semi-sweet chocolate chips
5 cups regular oats

Beat all together. Roll tablespoons of dough into golf ball size. Place on baking sheets. Bake at 400 degrees for 10-15 (For my oven I usually only have to cook them for about 9 minutes) minutes on upper racks.
