Oatmeal Cookies

No. Instant oats are too finely ground and create a mushy, dense cookie; old-fashioned rolled oats are essential for the signature chewy texture and visible oat pieces. Use only old-fashioned rolled oats.

Yes. Raisins are traditional but optional; omit them or substitute 1/2 cup of chopped dried cranberries, dried cherries, chocolate chips, or chopped walnuts. Add dried fruit or nuts after folding in the oats.

Yes. Cover the dough with plastic wrap and refrigerate for up to 3 days, or freeze for up to 1 month; thaw in the refrigerator overnight before scooping and baking. Baked cookies keep in an airtight container at room temperature for up to 5 days.

You have likely overbaked them or used too much flour; remove them from the oven when the center still looks slightly soft (they will firm as they cool), and measure flour by spooning and leveling, not packing. Also verify your oven temperature with a thermometer.

Yes. Add 1/4 teaspoon of nutmeg, a pinch of ground cloves, or 1/4 teaspoon of ground ginger along with the cinnamon; these warm spices complement oatmeal nicely. Keep the total spice at about 3/4 teaspoon to avoid overpowering the oat flavor.

These are the old-fashioned version—soft, chewy, and studded with rolled oats and warm spices. Modern variations may include more sugar, flavorings, or mix-ins; this recipe is the authentic classic.
