I made cookies for my Dad's dental office for a lot a years and these oatmeal cookies always seemed to be a favorite.
1/2 cup butter, room temperature
1/2 cup shortening
1 cup brown sugar
1 cup granulated sugar
2 teaspoons baking soda
1 teaspoon salt (I like a heaping teaspoon)
1/2 teaspoon baking powder
1 tablespoon vanilla
2 1/4 cup all-purpose flour
2 cups old fashioned oats
Cream together sugars, butter, and shortening. Add eggs one at a time and beat until light and fluffy. Add baking soda, salt, baking powder and vanilla. Add flour and oats and mix until incorporated. Place balls of dough on a cookie sheet lined with parchment paper and bake at 350 degrees F for 10-12 minutes.
