Adapted from Everyday Food, November 2003
1 1/4 cups rolled oats
3/4 cup all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1/2 teaspoon ground cinnamon (optional-I did not use because I don't love cinnamon but a lot of you do)
1/2 cup (1 stick) unsalted butter, room temperature
1/2 cup packed light-brown sugar
1/4 cup granulated sugar
1 large egg
1 teaspoon vanilla extract
1 1/4 cups of your favorite mix-ins (any single or combination of white/dark/milk chocolate chip, small diced dried fruit, chopped nuts)
Preheat oven to 350 degrees. Line two cookie sheets with parchment paper and set aside.
In a medium bowl, combine oats, flour, baking powder, salt and cinnamon (if using); set aside.
In the bowl of an electric mixer, cream butter and sugars on medium speed until smooth; beat in egg and vanilla.
With mixer on low speed, add oat mixture, and mix until just combined. Stir in mix-ins by hand.
Using a two-teaspoon ice cream scoop (or two teaspoon) drop dough onto lined cookies sheets and bake for 15 minutes until golden
Transfer to wire rack to cool completely.
Yield: 40 cookies
