Oatmeal-Chip Cookies/Bars

3/4 cup butter, softened
1 cup packed brown sugar
1/2 cup granulated sugar
1 tsp baking powder
1/4 tsp baking soda
1/4 tsp salt
1/2 tsp ground cinnamon (optional)
1/4 tsp ground cloves (optional)
2 eggs
1 tsp vanilla
1 1/2 cups all-purpose flour
2 cups rolled oats
1 cup semi-sweet chocolate, butterscotch-flavored, or peanut butter-flavored chips

1. Preheat oven to 375. In a mixing bowl beat butter with an electric mixer on medium high speed for 30 seconds. Add brown sugar, granulated sugar, baking powder, baking soda, salt, and, if desired, cinnamon and cloves. Beat until combined, scraping sides of bowl. Beat in eggs and vanilla. Beat in as much of the flour as you can. Stir in remaining flour. Stir in rolled oats. Stir in chips.
2. For cookies: Drop by rounded teaspoons 2 inches apart onto an ungreased cookie sheet. Bake for 8 to 10 minutes or until edges are light brown. Cool on cookie sheet 1 minutes. Transfer to a wire rack and let cool.
OR
For bars: Press into an ungreased 10x13-inch baking pan. Bake for 20 minutes (I think this is right... I forgot to set the timer), or until a toothpick inserted in center comes out clean. Cool on a wire rack. Cut into bars.

I made half of this recipe as bars, and the other half as cookies. I definitely preferred the bars - they were denser and more moist. I will stick to just bars next time.
