10oz(2 ½ sticks) cool unsalted butter, cut into chunks(280 grams)
1teaspoonsaltcut in half if using salted butter
½cupgranulated sugar(100 grams)
¾cuppacked light brown sugar(150 grams)
1largeegg
1tablespoonvanilla extract
1 ½cupsall-purpose flour, weight it or stir well before measuring(190 grams)
1teaspoonbaking powder
3cupsold fashioned or quick cooking oats
1 ½cupsdark or bittersweet chocolate chips**
1cuptoasted nuts or roasted almondschopped (optional)
Instructions
Preheat oven to 350 degrees F.
In the bowl of a stand mixer fitted with a paddle attachment, beat the cool butter until creamy. Add salt and both sugars and continue beating until smooth -- don't try to beat until fluffy or light, just smooth. Add the egg and beat just until mixed, then beat in the vanilla.
Mix together the flour and the baking soda. Stir flour mixture into the egg mixture until blended. Stir in the oats and the chocolate chips.
Scoop up about 32 heaping tablespoons of batter and shape into balls. Press tops of balls down slightly to make discs. Chill the balls until ready to use or bake immediately.
To bake, arrange dough pieces about 2 ½ inches apart on parchment lined baking sheets. Bake for 12 to 15 minutes or until cookies appear set. Let cool for about five minutes on baking sheets, then transfer to a wire rack and let cool completely.
Notes
I liked these best when they were completely cool and the chocolate chips had set.For jumbo size cookies, make 16 balls of dough and press them down slightly. Put the cookies in a 350 degree oven, but turn the heat down and bake them 1t 325 F for about 18 minutes.Since the cookies are large and fat, I used large chips. Nestle’s new dark chocolate chips are slightly larger, as are Ghirardelli’s Bittersweet. Chocolate chunks would probably be great too, but using chocolate cut into chunks may cause a little more spreading.
