Grandma's Old Fashioned Oatmeal Cookies

Ingredients

1 cup unbleached flour
3/4 teaspoon baking powder
1/2 teaspoon baking soda
14 tablespoons unsalted butter (1 3/4 sticks at room temp)
1 cup granulated sugar
1/4 cup light brown sugar (packed)
1 large egg
1 teaspoon vanilla
2 1/2 cups old fashioned oats (old fashioned type no instant stuff)

Directions

1 Heat oven to 350°F - you will need 3 baking sheets lined with parchment paper (again the parchment keeps the cookie from burning and makes clean up faster).

2 Whisk together flour, baking powder, soda and salt.

3 Beat together with mixer at low speed - butter and sugar until the sugar granules are not visible. Increase speed and beat 1 minute longer, scrape sides as needed and add egg, beat another 30 seconds. Add flour mixture 1/3 at a time and incorporate well over med speed until mixture is smooth. Add oatmeal and stir into the dough using your rubber spatula.

4 Divide into 24 equal portions and bake for 13 to 16 minutes placing only one cookie sheet in the oven at a time and rotating the cookie sheet half way through your cooking time -- these are the best and the thinnest cookies and very crispy.
