Easy One-Bowl Oatmeal Cookies Recipe (2024)

Why It Works

  • Warm butter provides moisture to hydrate the oats, which thicken the dough after a short rest.
  • Dried cranberries or cherries balance the sweetness of the dough.
  • Traditional all-purpose flour offers the right starch and protein content for tender cookies that spread as they should, so steer clear of unbleached alternatives.

I'm absolutely indiscriminate about good cookies. Snappy, chewy, sandy, crispy—whatever it is, I'll take two. I like making macarons, and florentines, andOreos, and fussy cookies that take all day. I don't mind busting out a cloth cover to painstakingly roll out my aunt Donna'spepparkakor, and it's no bother to keep raw cane sugar on hand for absurdlyperfect gingersnaps.

And yet, I find myself making oatmeal cookies more than any other. When I'm at home, everything else seems like Schrödinger's cookie: an interesting possibility. But oatmeal cookies are so real I can smell them, and once I've got that butterscotch-y aroma in mind, I can taste them. Warm and soft and chewy and crisp around the edges.

When it gets to the point that I'm fantasizing about imaginary cookies, I'm halfway to the kitchen.

The wild and unpredictable onset of my craving has taught me a lot about oatmeal cookies, because it makes me impatient. On the one hand, it's helped me develop a one-bowl recipe that comes together as quickly as I can scale the ingredients. On the other, it's shown me that certain corners refuse to be cut.

When Is Butter Melted Just Right?

The first is melted butter, and little baby Goldilocks has to have things just right. Too cool, and the grainy dough refuses to spread. Too hot, and it's an oily mess that oozes in a puddle (though said puddle istasty, all butterscotch-y and crisp). But when the butter is warm and fluid, about 105°F (41°C), give or take five degrees, everything's perfect.

Sugar dissolves a bit in the warmth, while rolled oats and flour soak up the water, making a dough that's smooth and easy to handle. The cookies themselves bake up chewy and crisp, though the first tray has always looked more irregular than the second, which never bothered me at all. I figured it had something to do with dough temperature, and the urgency of my cravings cared nothing for aesthetics. So far as I was concerned, it was a cook's treat: those funky, unpresentable bits that are always scarfed while you stand at the stove. I kept the uglies for myself and sent the beauties to friends and neighbors.

Most of the time.

Resting the Batter Is Key

Eventually, my oatmeal cookie fascination got the better of me, and I stole a bite from the second tray. A light shone all around, and I basked in the glory of revelation: It wasn't the dough temperature, it was the oats!

Whether old-fashioned or thick-cut, rolled oats are made by roasting and steaming whole oat groats, then sending them through a roller. (Obscure knowledge bomb—instant oats are made the same way, but with steel-cut oats.) Anyhow, steam does something interesting: It pre-gelatinizes the starch, making rolled oats soluble in cold water.

That lets them swell up with moisture from the dough, and when grains swell, they soften. So the oats in the second batch get tenderer, the dough gets thicker, and everyone but me gets a better cookie. Oh, the irony of my impatience!

Since then, I've learned that perfect oatmeal cookies are worth the wait. Twenty-five minutes (roughly the time that passes between adding the oats and getting my second tray in the oven) of resting time is enough to see a distinct improvement; 45 is even better. After an hour, the baking soda starts to lose its strength, but you still won't notice any negative effect on your cookies until about the 90-minute mark. Holding the dough overnight is out of the question.

That's okay, though. You'll be making them again soon enough.

PS: Swap out traditional raisins for tart dried cranberries or cherries. They balance out the sweetness of the cookies so much better.

Notes

If the temperature drops below 70°F (21°C) in your kitchen, the cookie dough may solidify as it rests. If possible, set the trays of cookie dough on the stovetop, where heat from the oven will knock off the chill.

Due to the melted butter that brings the baking soda in contact with brown sugar, this dough will not keep overnight in the fridge.

In this recipe, unbleached flour will prevent the dough from spreading as it should.

FAQs

Why are my homemade oatmeal cookies hard? ›

Not Enough Moisture: Ensure you're using the right amount of butter in your recipe and that it's at the correct temperature (softened not melted) when you start. Oatmeal cookies require more moisture to stay soft. Consider adding an extra egg yolk or a touch of milk to your dough to enhance moisture content.

How do you keep oatmeal cookies from falling apart? ›

Let them cool completely before moving them around

Warm cookies are fragile and prefer to be left alone. If you move fresh cookies while they're too warm, they may crumble. Let them be until they cool off and firm up.

Why can't you use instant oats for oatmeal cookies? ›

I don't recommend using quick oats because the cookies won't have as much texture and you want a nice and chewy oatmeal cookie that is hearty with lots of texture going on. Quick oats also absorb liquid differently and you don't want to end up with dry cookies.

How do you keep oatmeal cookies moist? ›

The bread/apple trick

Here's a baker's trick you'll find in our new Monster Cookies recipe: Adding a piece of fresh white bread to the storage container will keep cookies from becoming hard or stale.

What is the secret to making cookies soft? ›

Baking cookies quickly in a hot oven – at 375 degrees F as opposed to a lower temperature – will make for soft results. They'll bake fast instead of sitting and drying out in the oven's hot air. Ever so slightly underbaking your cookies will give you softer results than cooking them the full amount the recipe says.

What ingredient makes cookies harder? ›

Baking powder

Baking powder contains sodium bicarbonate and acidic salts. The reaction of these two ingredients results in a cookie that is soft and thick, but slightly harder.

What happens if you put too much butter in oatmeal cookies? ›

Adding too much butter to your cookies can turn them from delightful treats to crumbly disasters! Here's why: Greasy mess: Extra butter means more fat, making the dough greasy and difficult to handle. Spreading like crazy: Cookies lose their shape, spreading thin and flat instead of staying nice and round.

Should oatmeal cookies be refrigerated before baking? ›

As a general rule of thumb, you should refrigerate cookie dough for at least 30 minutes and up to 24 hours. More than that, and you won't see a noticeable difference in the final product. Once the dough has chilled, let it warm up at room temperature until it's just pliable (about 5 to 10 minutes).

Should you let oatmeal cookie dough rest? ›

The short answer is: Yes. Resting your dough in the refrigerator will almost always yield better results. But why? Chilling your cookie dough in the refrigerator after mixing it allows the flour to hydrate and gives the other ingredients time to blend, resulting in a richer, more well-rounded flavor profile.

Can I substitute old-fashioned oats for quick oats in oatmeal cookies? ›

When it comes to the two types you probably already have in your kitchen—rolled oats and quick oats—you can use them in recipes interchangeably. If you need quick oats, but only have rolled oats, just pulse the rolled oats a few times in the blender to get the textural effect your recipe needs.

Can I use Quaker oats instead of rolled oats? ›

A: Absolutely! As I said, the benefits really don't differ between the three types of oats.

Why do you chill oatmeal cookie dough? ›

Cool down your dough for a tastier, chewier cookie.

There's a few reasons why, but one important part is it gives the butter in your dough a chance to firm up before baking. The colder your dough is before it heads into the oven, the less it will spread during baking, which makes for loftier cookies.

Why is my oatmeal cookie batter so dry? ›

Dry – “Dry” or “Crumbly” dough is a product of over-mixing or using too much of any ingredient during the mixing process. This can be reversed by adding one to two tablespoons of liquid (water, milk or softened butter) to your mix.

Does more butter make cookies softer? ›

Also, underbaking them by a minute or 2 will help them retain a dense, chewy bite, explains Jenny McCoy, pastry baking arts chef-instructor at the Institute for Culinary Education in New York. Adding more moisture to your dough in the form of extra butter, egg yolks, or brown sugar will make your cookies even softer.

Why are my cookies hard instead of chewy? ›

According to The Kitchn, this occurs when you over-mix the dough. Mixing the dough naturally causes gluten to develop in the flour, and while you do need a good amount of gluten to give your cookies structure, too much of it will result in hard cookies.

What makes homemade cookies get hard? ›

Over-baking is perhaps the most obvious - too long in the oven and your cookies will dry out, so make sure you time it right. Overworking your dough is another common problem, causing excess gluten strands to form, and making your cookie hard and tough. Fat content can be a cause.

Why are my oatmeal cookies flat and hard? ›

Oven temperatures are a crucial factor in baking. If your cookies consistently come out flat, you may have selected the wrong baking temperature. If you bake cookies using too much heat, the fats in the dough begin to melt before the other ingredients can cook together and form your cookie's rise.

Why are my cookies crunchy instead of soft? ›

Sugar dissolved in baking forms a syrup as the dough heats up. Different types of sugars affect the texture because they absorb different amounts of water. Remember moisture is the key! White sugar creates crispier cookies and brown sugar creates chewier cookies.
