Chocolate Chip Oatmeal Cookies With Peppermint

• 1 c all-purpose flour
• 3/4 c whole wheat flour
• 1 tsp baking soda
• 1/2 tsp salt
• 2 tsp cinnamon
• 1 1/4 c packed brown sugar
• 1 cup (2 sticks) butter or margarine, room temperature
• 1/2 c granulated sugar2 eggs
• 1 tsp vanilla
• 1 tsp peppermint flavor (Yes, flavor. That's what the bottle I got says. "Flavor" feels a little misleading, though, since the all-of two ingredients are 1. sunflower oil; and 2. peppermint oil. This is basically peppermint oil, people.)
• 2 1/2 c quick oats
• 2 c semi-sweet chocolate chips

Preheat oven to 375.
Whisk flours, baking soda, salt and cinnamon in a small bowl. Beat brown sugar, butter and granulated sugar in a large bowl until creamy. Beat in eggs, vanilla and peppermint. Mix in flour mixture. Mix in oats and chocolate chips. Drop by tablespoon onto ungreased baking sheets.
Bake for 10 to 13 minutes. Cool on baking sheets, then move to wire racks to cool completely.
