Why I Love This Recipe

These classic oatmeal cookies have everything I want in a homemade cookie: crisp edges, soft centers and plenty of buttery brown sugar flavor. They’re simple, dependable and always disappear quickly around here.

I also love how versatile the dough is. Keep them plain or turn the recipe into oatmeal raisin cookies or oatmeal chocolate chip cookies depending on what you’re craving.

  • Butter: Unsalted works best so you can control the salt in the recipe. Make sure it’s softened for smooth creaming.
  • Brown sugar: Packed light brown sugar gives that classic brown sugar oatmeal cookies flavor while adding chewy texture and warm caramel flavor.
  • Granulated sugar: Balances the sweetness and helps the edges bake up lightly crisp.
  • Eggs: Eggs bind the dough and keep the cookies soft.
  • Vanilla extract: Adds flavor and rounds out the sweetness.
  • All-purpose flour: Provides structure while keeping the cookies tender.
  • Salt. Enhances all the flavors. Reduce the added salt if using salted butter (about 1/4 teaspoon or skip it).
  • Baking soda and baking powder: Give the cookies lift and a tender texture.
  • Old-fashioned oats: Rolled oats give the best chewy texture. You can use quick oats, but the cookies turn out softer and can dry out a little. A mix of both works too.

Fun Variations to Try

How to Make Easy Oatmeal Cookies

These come together fast in one bowl, no chilling required. In a large mixing bowl, use an electric mixer to cream the butter, brown sugar and granulated sugar until smooth. Add the eggs and vanilla and mix until combined.

Add the flour, salt, baking soda and baking powder (plus cinnamon if you’re using it) right into the same bowl. Stir just until combined, then mix in the oats. Don’t overmix, a few quick strokes keeps the cookies tender.

Scoop the dough with a medium cookie scoop onto a baking sheet lined with parchment or a silicone mat. Because this recipe uses just the right amount of sugar, the dough holds its shape and bakes up thick instead of spreading thin.

Bake at 350°F until the edges are just light golden, about 8 minutes, the centers should still look a little underdone. Let them rest on the pan for 2 minutes, then move to a rack and enjoy warm.

Recipe Tips

  • Use room temperature butter and eggs: They mix more smoothly into the dough and help the cookies bake evenly. To quickly warm eggs, place them in a bowl of warm water for a few minutes. Soften butter in short microwave bursts if needed.
  • For softer or crispier cookies: Pull them from the oven when the centers look slightly underdone for a soft, chewy texture. Bake a minute or two longer if you prefer crispier edges.
  • Prevent spreading: This recipe holds its shape well, but if your kitchen runs warm, chilling the dough 20–30 minutes keeps the cookies thick.
  • Scoop for even baking: A cookie scoop keeps the cookies the same size, and lining the pan with parchment paper prevents sticking.
  • Finishing touch: For a sweet-salty bite, sprinkle flaky sea salt on top before baking.

Easy Oatmeal Cookies FAQs

What type of oats are best for this oatmeal cookie recipe?

Old-fashioned rolled oats are best because they give the cookies their classic chewy texture. Quick oats will work, but the cookies may turn out a little softer and drier. I don’t recommend steel-cut oats for this recipe.

Why did my oatmeal cookies spread too much?

Make sure your butter is softened but not melted and measure the flour accurately. If your dough feels especially soft or your kitchen is warm, chill it for 20 to 30 minutes before baking. The dough should hold its shape when scooped.

Why are my oatmeal cookies dry or hard?

Overbaking is usually the culprit. Remove the cookies when the edges are lightly golden but the centers still look slightly underdone. They’ll continue to set as they cool on the baking sheet.

Can I make oatmeal cookie dough ahead of time?

Can I make oatmeal cookie dough ahead of time?
Yes. Cover the dough and refrigerate it for up to a couple of days, then let it sit at room temperature briefly if it’s too firm to scoop. You can also freeze scooped cookie dough balls and bake them straight from frozen, adding a minute or two to the baking time.

Notes

If I have molasses on hand I love adding 1-2 teaspoons. 
Mix in 1 cup of raisins, chocolate chips or butterscotch chips. 
Use unsalted butter (recommended). If using salted, cut the added salt down to about 1/4 teaspoon or skip it altogether, since the butter already brings salt and amounts vary by brand.
Storage: Store in an airtight container up to 3 days. Adding a slice of white bread to the container helps keep them soft. Freeze baked cookies up to 3 months, or freeze raw dough balls (flash freeze until firm, then bag) and bake from frozen, adding a couple minutes to the time.
Less spread: This has been retested and brown sugar reduced to 1 cup so the cookies hold their shape while baking. If you prefer sweeter cookies, use 1 1/4 cups brown sugar, but know that they will spread more.
