Scottish-style shortbread influence comes from the cornstarch and finely ground oats, which give a tender, sandy crumb with a bit of heartiness, so avoid overmixing once the flour goes in to keep them delicate. If you prefer crisper edges, extend bake time by 1–2 minutes; for chewier centers, pull them as soon as the edges color. Use chopped chocolate for pockets that melt more dramatically, and reserve a few chips to press on top before baking for a bakery look. Weighing ingredients improves consistency, and a 30–60 minute chill controls spread. Cookies keep 4 days airtight at room temperature or freeze dough balls for up to 2 months and bake from frozen adding 1–2 minutes.
