I love Chewy Oatmeal Cookies!! I feel like oatmeal is the forgotten cookie, but they’re SO good. I always forget how much I love them until I make them again. These are soft oatmeal cookies you can make with different add-ins and for different dietary restrictions and I’m going to show you all of them!

Soft & Chewy Oatmeal Cookies

Oatmeal Cookies are the underdog of cookies, but don’t count them out! I think they’re actually my favorite cookie, I just forget until I make them and then I’m like, oh yeah, these are my favorite!

However, I do have some requirements for my oatmeal cookies. They must be:

  • Soft (no crunchy cookies allowed)
  • Chewy texture
  • Flavorful from the cinnamon, even if I make them plain

The perfect oatmeal cookie is a blank canvas, just like a chocolate chip cookie. It’s the perfect vehicle for adding your favorite mix-ins and flavors to.

Consider this post your ULTIMATE OATMEAL COOKIE GUIDE. I’m going to teach you everything you need to know to make the BEST cookie ever!

Ingredients in OATMEAL cookies.

Ingredients Needed

  • Butter: use real butter, okay? I use unsalted butter in this recipe, and you need to start with it softened. Learn how to soften butter quickly here. Butter substitutes and low-fat butter won’t work in these cookies. The only exception to that rule is if you use Earth’s Balance Vegan Butter Sticks (those are a 1:1 sub for butter).
  • Brown Sugar: instead of mixing sugars in my cookies, these are a brown sugar oatmeal cookie. I love the flavor that brown sugar gives to recipes, plus it adds to the oatmeal flavor of the cookie and keeps them soft for days.
  • Flour: as written, the recipe uses all-purpose flour. See below for substitutions.
  • Quick Cooking Oats: I find that old fashioned oats are okay in these cookies but I prefer quick cooking oats because they make chewy oatmeal cookies without being too much. You can make your own quick cooking oats from rolled oats by pulsing them a few times in a blender or food processor.

Tips for making Chewy Oatmeal Cookies

Cookie dough is probably one of the easiest things you can make, but these tips will make it a little bit easier.

  • Be sure to cream your room temperature butter and sugar before adding any other ingredients.
  • Whisk together your dry ingredients before adding to the wet ingredients.
  • You can make these cookies with a hand or stand mixer.
  • Be sure to use baking soda in the cookies (not baking powder).
  • Don’t forget to chill the cookie dough. This ensures a puffy soft and chewy cookie!
  • I prefer baking cookies on silicone baking mats (Silpats) but you can also use parchment paper.
  • Make these cookies any size (photos shown are 2 tablespoon size) or shape: you can make them small bite sized using a 1 tablespoon scoop, or make them into a cookie cake or bar cookie.
  • How do you know when your cookies are done? They’ll be golden around the edges and have just lost that glossy sheen on top.

How To Make Oatmeal Cookies From Scratch

  • Cream the butter and brown sugar on low speed. Add the egg, vanilla, cinnamon, baking soda, and salt. Mix in the flour.
  • Mix in the quick oats. Drop cookie dough balls onto prepared cookie sheets using a cookie scoop. Chill at least 1 hour.
  • Bake the cookies at 350°F. You know they’re done because they are lightly golden around the edges and they’ve just lost their glossy sheen.

Mix In Options

I’m showing you four different versions of cookies today, but the options for making different flavors is endless!

  • Chocolate Chip Oatmeal Cookies are a huge hit. Simply adding chocolate chips to your batter make one of my favorite oatmeal chocolate chip cookies!!
  • Oatmeal Raisin Cookies are a classic. I don’t like raisins, so these aren’t my first choice, but a lot of people love them!
  • M&M Oatmeal Cookies – I love adding M&Ms to cookies. I’ve done it to peanut butter, chocolate chip, and sugar cookies – any cookie can benefit from M&Ms!
  • If you want to make oatmeal cookies with peanut butter, try my recipe for peanut butter oatmeal cookies too!
  • Add chopped peanut butter cups or Reese’s Pieces, add nuts, swap pumpkin pie spice for the cinnamon – so many options!

Dietary Substitutions

I have tested these oatmeal cookies with a few different ingredients in case you’re on a special diet or can’t find certain ingredients.

  • Make these cookies Gluten-Free by using Bob’s Red Mill 1 to 1 Gluten Free Baking Flour (light blue bag). (Substitute it equally for the AP Flour.) Be sure that you use Quaker Gluten Free Oats too – regular oats are naturally gluten-free but sneaky bits of gluten can sneak into the batch, so Quaker has a completely GF line.
  • Make these with whole wheat flour by substituting 1/2 cup whole wheat flour with 1/2 cup all purpose flour. (Using all whole wheat flour requires other changes to the dough.)
  • You can substitute bread flour equally for the all purpose if you don’t have AP flour.
  • You can make these sugar free by using 1 1/4 cups of Swerve Brown Sugar. It’s the only completely 0 carb brown sugar on the market and really does taste good in recipes!!
  • Make them dairy-free by using Earths Balance Vegan Butter Sticks in place of butter (and omit any dairy add-ins, obviously).

  1. Excellent recipe. I didn’t have unsalted butter so I used the salted butter. Next time I make them I will cut the salt asked for a little bit but they sure were delicious!
