Seth's Chocolate Chip Cookies

1 cup (2 sticks) butter

1 cup dark brown sugar

1/2 cup white sugar

1 large egg

1 large egg yolk

1 tablespoon vanilla extract

2 cups all-purpose flour, lightly spooned into measuring cups and leveled with a knife (very high altitudes may want to try adding 2 additional tablespoons of flour)

1 cup quick-cooking oats

1 teaspoon baking soda

1 teaspoon baking powder

1 teaspoon kosher salt (or 3/4 teaspoon table salt)

2 cups chocolate chips 

Preheat oven to 375. 

Beat the softened butter, sugar, and brown sugar until light and fluffy. Add the egg, egg yolk, and vanilla and mix until combined.

In a separate bowl, combine the dry ingredients (except the chocolate chips). Add to the butter/sugar/egg mixture and mix until combined. Add the chocolate chips and mix until just combined.

Drop the dough by the spoonful onto baking sheets.  Bake in the preheated oven for 12-15 minutes or until they begin to turn light brown around the edges. Remove from the oven and cool for 5 minutes and then transfer to a wire cooling rack and cool.
