Rolled Oats vs Quick Oats in Baking
Oats are a popular baking ingredient, whether youโre baking a batch of oatmeal cookies or making a simple fruit crisp. The two types of oats most often used in baking are rolled oats and quick oats. While theyโre quite similar, there are some differences that will come through when baking with them.
What Are Oats?
Letโs start simply with oats, which are a type of cereal grain. The whole oats are called oat groats. Both rolled oats and quick oats come from the same grain, but they are processed differently. If youโve ever looked at these two types side by side, you can easily see the difference in the sizes of the pieces.
What Are Rolled Oats?
Rolled oats, also known as old-fashioned oats, are made by steaming and flattening whole oat grains. They have a chewy texture when raw, but soften when cooked or soaked. Rolled oats are commonly used in recipes for oatmeal cookies, quick breads, muffins, and other baked goods.
The larger size of these oats create a chewy texture when added to baked goods. The pieces of oats tend to keep their shape through baking, lending to that hearty texture.

What Are Quick Oats?
Quick oats, also known as instant oats, are rolled oats that have been cut into smaller pieces and rolled even thinner so they cook faster. Because of their smaller size, quick-cooking oats are often used in recipes that might benefit from a less chewy texture.
They can be added to baked goods like cookies or muffins when you want the flavor and some of the texture of oats but a little less of that hearty chewiness usually associated with oats.
Although they are sometimes called instant oats, donโt confuse these with pre-cooked instant oats.

Substituting Types of Oats
Generally speaking, rolled oats and quick oats can be swapped for each other in most baking recipes. You can do this because of your own preferences or just when you find yourself without the kind you need. While the taste is largely unaffected, you can expect differences in the end result. There are just a few things to keep in mind when making a substitution.
- Measurements โ I usually recommend making the substitution by volume instead of by weight. In my experience, a cup of one doesnโt quite weigh the same as a cup of the other. It may not make much of a difference in smaller amounts, but itโs good to keep in mind.
- Texture โ Youโll get a chewier texture with rolled oats, and less chewiness with quick oats.
- Shape โ These two types of oats donโt incorporate into a dough quite the same way. This is less relevant if youโre baking a cake or making a crisp topping, but youโll often see a difference in overall shape and size when making cookies.
- Baking time โ Because of the difference in their size, recipes made with rolled oats may take slightly longer to bake than those made with quick oats. This will vary depending on what youโre making and how much of an oat component is present. You may find that it doesnโt make a difference at all, but it is worth keeping in mind.
Cookies Made with Rolled and Quick Oats
To show you the differences you might see when swapping one type of oat for the other in baking, I made two batches of simple oatmeal cookies. One batch was made with rolled oats, while the other was made with quick oats. You can see above the differences in the dough and the cookies. While the flavor is largely unaffected by this change, the size, spread, and texture are all altered to some degree.
Other Types of Oats
Oat flour is made from ground rolled oats. While oat flour is usually gluten-free, itโs also used in combination with wheat flours. While you can purchase oat flour, making it yourself from rolled oats is a simple process. All you need to do is grind rolled oats in a food processor or blender until a fine powder is formed. You can see ground oats used this way in my Favorite Chocolate Chip Cookies.
Steel-cut oats, also known as Irish oats or Scottish oats, are made from whole oats that have been chopped into small pieces. Theyโre more coarsely ground than rolled or quick oats, and they take longer to cook and tend to retain their chewy texture and shape. Because of this, they arenโt frequently used in baking and shouldnโt be used as a substitute for rolled or quick oats.

6 Comments on โRolled Oats vs Quick Oatsโ
Thank you for this explanation. I make a lot of fruit crisps and recently encountered the differences in oats when I substituted rolled oats for the plain instant oats on one batch of topping. Oh my, what a difference. As you said the taste wasnโt affected, but the chewiness of oats in the topping was glaring. Fruit crisps donโt usually require a lot of chewing, but this did. Next time, Iโll go back to my old instant oats for my toppings.
I do like the steel cut oats for breakfast though.
Iโm glad you found this helpful, Maxine! It can be surprising the difference the two kinds can make.
Thanks for this explanation. I found it very helpful. So if a recipe calls for 2 cups rolled oats, could I use 2 cups of instant oats, or should I increase the volume of instant oats?
Iโm glad you found it helpful, Sarah! Yes, you can make that substitution. Just make sure the oats arenโt the pre-cooked kind.
Thank you for this excellent clear article about the complexities of baking with oats. I absolutely need to watch texture because I am making dog cookies and it has to be right. You have help me see why Iโm getting variation and I now understand what to do. Beautiful, concise clear article.
Thanks, Jan! Iโm glad you found it helpful!
