Crushing the oats slightly (with your hands or a rolling pin) helps them toast evenly and creates a crunchier edge without making the cookies dry. If the dough feels oily or too soft after mixing, chill an extra 10 to 15 minutes for thicker cookies. For chewier cookies, pull them when the centers are puffed but still soft; for crisper edges, bake an additional 1 to 2 minutes. Swap chocolate chips for chunks for pockets of melty chocolate, and use a mix of milk and dark chips for depth. These cookies freeze well: freeze scooped dough balls on a tray, then bag and bake from frozen adding 1 to 2 minutes to the bake time. Adjust salt to taste if using salted butter by reducing added salt to 1/4 teaspoon.
