The Best Oatmeal Raisin Cookies Ever

I've made a handful of oatmeal raisin cookies over the years, since that's my favorite kind, find recipes everywhere from cookbooks to the top of an oatmeal container. But these are my all-time favorite, adapted from bits here and bits there, and tested many times over.

Ingredients:
1 stick butter
1/2 c. sugar
1 egg
1 tsp vanilla
1/2 c. white flour
1/2 c. whole wheat flour
3/4 c. rolled oats
1/2 tsp baking soda
1/2 tsp cinnamon
1/2 c. raisins
 


Directions:
Preheat oven to 375.
Cream butter in a large mixing bowl.
Gradually add sugar and cream into butter.
Add egg and vanilla and mix well.
In a separate bowl, mix flours, baking soda and cinnamon.
Add to butter mixture and mix well.
Add oatmeal and raisins and mix well.
Form into cookies of desired size on a buttered or nonstick cookie sheet.
Bake 10-12 minutes.
