Peanut Butter Oatmeal Cookies

Peanuts, oats, flour, and only brown sugar instead of white sugar make for a sweet and savory, super peanut forward flavor and a great texture with these cookies.

Feel free to play around with the final texture of these cookies by changing the baking time or adding a bit more or less flour; the best thing about cookies is how customizable they are!

Just make sure you cool these cookies properly, or they are liable to fall completely apart!

How To Get Different Textures Of Cookies

If there is one truth about making and enjoying cookies, it is that everyone seems to like them in different ways.

Some people prefer thicker, tougher cookies to chew on, whereas others prefer soft and gooey, or even thin and crispy – all of these different styles are achievable by changing up the ratios of ingredients and cooking them differently.

For a softer cookie, try and underbake them just a little bit, pulling them maybe a minute or two early. If you do this, make sure that you let them cool completely on the baking sheets; otherwise, they will completely fall apart!

For a crispier cookie, bake for 2 more minutes until golden brown. These ones you can safely remove to a cooling rack without risk of them falling apart.

For thicker cookies, you need to adjust the ratios of ingredients. For thick cookies, up the flour by an extra 1/8th of a cup and maybe over mix it just a little bit to get a tougher texture.

What Kind Of Peanut Butter Should You Use For This Recipe?

This recipe calls for using natural peanut butter, as well as whole salted peanuts that have been very coarsely chopped.

For many people that are used to only regular peanut butter from the store, the idea of natural peanut butter might seem strange.

Natural peanut butter is peanut butter made from nothing more than ground and blended peanuts, along with a little bit of oil, which is usually olive oil or peanut oil. Natural peanut butter tends to not contain any sugar or palm oil and is a lot more savory and peanut forward than regular commercial peanut butter.

If you struggle to find natural peanut butter around where you live, why not make it yourself? Simply crush some good quality peanuts in a mortar and pestle or mixer with a blade attachment and drizzle in some oil into it forms the texture of peanut butter.

The key is to avoid any processed ingredients and avoid any extra sugar. Plus, natural peanut butter tastes way more like peanuts!

    Came out completely flat and falling apart! Double and triple checked I got everything in and I did. What a waste of ingredients!

  2. Rebecca says

    very delicious cookies but I think the flour measurements are wrong. My cookies taste great however when pulling them out of the oven they were very flat. They crumble apart like granola. How much flour should be added? 1/4 cup doesn’t seem like enough3 stars

  3. Sam says

    I tried this recipe, but the cookies came out completely flat and falling apart, and look nothing like the pictures. I tried refrigerating the rest of the dough before baking, but it didn’t help. I suspect there is not enough flour in this recipe, which isn’t surprising given it only calls for 1/4 cup of flour. Was this a typo or something??

    At least they still taste good.

  4. Nancy says

    These are DELICIOUS – just made them! I even substitued 1/8 cup of the flour for quinoa flour (can’t taste the difference) and just a wee bit more healthy. This is a keeper for sure. Thanks!

    • Karlynn says

      It contains no sugar, no hydrogenated oil, sometimes a little salt.
