Rolled Oat Cookies

These are icebox cookies, which means you make the dough, shape it into logs, chill until firm, and slice off whatever you want to bake. Round, tidy, and perfect for dropping into a lunchbox or alongside afternoon tea. No dough-ball rolling, no uneven cookies.

The formula is classic: butter creamed with brown sugar, a little water and vanilla for moisture, and quick-cooking oats stirred in with flour. The absence of egg is what makes these slice-and-bake instead of drop-style. The dough is firmer and holds its log shape cleanly in the fridge.

Brown sugar adds a subtle molasses note that makes these taste like oatmeal cookies should, earthy and rich rather than just sweet. The quick-cooking oats, not old-fashioned rolled, give a finer texture that slices without crumbling.

Chef Tips

• Wrap the dough logs in waxed paper or plastic wrap and chill at least 2 hours. Under-chilled dough won’t slice cleanly.
• Use a sharp thin knife and rotate the log a quarter turn after each slice so the rounds stay round.
• Slices should be ½ inch thick. Thinner and they burn at the edges before the centers set.
• Bake only until lightly browned at the edges. Oat cookies firm up as they cool.

Variations

• Add ½ cup chopped pecans, walnuts, or raisins to the dough.
• Roll the logs in turbinado sugar before slicing for a sparkly, crunchy edge.
• Swap ¼ teaspoon of cinnamon or freshly grated nutmeg into the dry ingredients.
