Chocolate Chip Oatmeal Cookies (King Arthur) - or bars

These are so good, our new favorite.  This is from King Arthur's 2015 Recipe of the Year - my only changes are to use dark brown sugar instead of light, and I put in fewer chocolate chips.  Yes - one tablespoon vanilla!

IN TOKYO 2019- much easier to make bar cookies:
1.  melt the butter
2.  I used quick oats
3. line 9x13 inch pan with parchment paper
4.  Bake at 160 degrees Celcius - for 22 minutes. 
- consider using two whole eggs - and bake a couple minutes longer. 

Makes 4 dozen small - 

2 sticks butter, room temp - 226 grams 
1 C dark brown sugar, packed
1/2 C granulated sugar
1 large egg
1 large egg yolk
1 T vanilla extract
2 C all purpose flour
1 C rolled oats (old fashioned)
1 tsp baking powder
1 tsp baking soda
1 tsp salt
12 oz package (2 C) chocolate chips - I like Ghidardelli semi sweet


Preheat to 325 degrees.

Beat butter and sugars til smooth; add eggs and vanilla, beat til incorporated.  Mix dry ingredients together and add to the dough, mix well.  Stir in chocolate chips.

Bake about 10 minutes, until lightly golden with slightly darker edges.
