Good-As-Store-Bought Cookies (King Arthur Flour) - cooking recipe

Ingredients

2 1/2 cups rolled oats, finely ground
8 ounces semisweet chocolate (or bittersweet or milk)
1 cup unsalted butter
1 cup brown sugar
1 cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
2 cups unbleached all-purpose flour
1 teaspoon salt
1 teaspoon baking powder
1 teaspoon baking soda
1 tablespoon espresso powder
2 cups semi-sweet chocolate chips
1 1/2 cups walnuts, chopped (or pecans)

Preparation

Preheat the oven to 350. Line cookie sheets with parchment paper.
Grind the oats and 8 ounces of chocolate together in a food processor. Set aside.
In a large mixing bowl, cream together the butter, sugars, eggs, and vanilla.
In a separate bowl, whisk together the flour, salt, baking powder, baking soda, espresso powder and the reserved oat/chocolate mixture. Add the dry ingredients and stir to combine.
Stir in the chocolate chips and nuts.
Use a tablespoon cookie scoop to drop the dough onto the cookie sheet, leaving 2 inches between then so they can spread.
Bake for 12 minutes; don't overbake, or they'll be hard.
Remove from the oven and transfer to a rack to cool.
