Mixed in a single bowl and ready to eat in about half an hour, this recipe is perfect for spontaneous weeknight baking. The dough freezes beautifully, letting you portion and stash it for fresh-baked cookies on demand—ideal for packed schedules or unexpected company.
Unsalted butter, softened, 1 cup (2 sticks)
Preheat the oven to 350 °F
Chef’s Note: For deeper flavor, toast the rolled oats in a dry skillet until lightly golden before folding them into the batter—it adds a subtle, nutty crunch. If you like a thicker, chewier cookie, chill the portioned dough for at least 20 minutes; the colder butter slows spread in the oven. Finish the warm cookies with a pinch of flaky sea salt to sharpen the caramel notes.
