There is truly nothing like the combination of peanut butter and chocolate in my opinion.

It’s just iconic. Like Mary Kate and Ashley, Britney Spears and Justin Timberlake, or Mickey Mouse and Pluto.

So if you’ve never peanut butter and chocolate in cookie form, you can imagine that the combo is pretty jaw dropping.

In fact, since the birth of this recipe, my family has requested this one, over all of my other recipes, over…and over…and over again haha! At this point, I’m pretty sure I could keep my local grocery store afloat just on the amount of oats and peanut butter and chocolate chips I’ve been buying haha!

Let me break it down for you. These soft and chewy peanut butter oatmeal cookies are:

  • Packed with peanut butter and chocolatey goodness
  • Sweet enough to hit the spot yet not drown out the other flavors
  • Soft yet firm enough to not need a napkin 😉
  • Undetectable healthy

Yep, I said it! These are healthy oatmeal cookies, but judging by how my family (and myself) devour them every time, you’d never know!

So don’t freak out that you need to be vegan or gluten free to eat these both gluten free and vegan oatmeal chocolate chip cookies!

It’s simply just a combination of amazing ingredients together that just so happen to make these chewy peanut butter oatmeal cookies protein packed, low in sugar, and completely dairy free and egg free.

I give credit to peanut butter and chocolate. There’s nothing that duo can’t do!

Ingredients to make Peanut Butter Chocolate Chip Oatmeal Cookies

What’s really cool about these oatmeal cookies is that the ingredients are pretty basic. In fact, most of them are kitchen staples!

The only ingredients you’ll need are:

  • Rolled oats (these can be gluten free or regular)
  • Cassava flour (or your favorite 1-to-1 gluten free flour, or all-purpose flour)
  • Unsweetened applesauce (feel free to make your own!)
  • Coconut sugar (or maple syrup or cane sugar)
  • Peanut butter
  • Ground flaxseed with water
  • Chocolate chips

I’m telling you, these cookies are almost too easy!

Why these are the easiest oatmeal cookies you’ll make

Well, friend, these cookies can literally come together in 20 minutes, tops. I’m not joking. There’s no chill time whatsoever!

I know, right? This is because these gluten free oatmeal cookies don’t contain any butter, so there’s no need for them to spend time in the cool fridge.

Like in the recipe video above, all you really need to do with these oatmeal cookies is mix all of the ingredients together, scoop it onto a cookie sheet, and bake!

A few notes about these cookies

I want you to experience these peanut butter oatmeal chocolate chip cookies in all of their glory, so let me make sure I’m giving you the proper run down on how to get the best cookies each time, even if you add in a few swaps 😉

Don’t worry, I won’t be offended! I used to go rogue on recipes as well haha!

So, tips to make the best chewy peanut butter oatmeal cookies:

  • Stick with rolled oats. Steel cut oats are a bit tougher to work with, and definitely won’t yield that soft texture you want in chewy oatmeal cookies
  • I recommend smooth peanut butter, but if you like more crunch in your cookies, go for crunchy!
  • For flour, I used cassava flour, but because cassava is a 1:1 flour swap (meaning you can swap in a regular flour at equal ratios), feel free to swap in a regular all-purpose flour at the same measurements, or my favorite 1-to-1 gluten free baking flour!
  • Use a spoon to press the cookies down. Now, because these are vegan oatmeal chocolate chip cookies, they don’t contain any butter (not even vegan butter!), so these cookies won’t spread on their own. Lightly press the top of the cookie dough ball onto the pan to flatten into a cookie shape, and you’ll be all set!
  • If you don’t need this recipe to be refined sugar free, you can absolutely use regular cane sugar!
  • On the note of sugar, using coconut sugar or maple syrup is fine here! There isn’t much sugar that goes into the cookies anyways that the texture still comes out right 🙂
  • I prefer using a cookie scoop to get the most even cookies, but feel free to use a tablespoon measure or just eyeball it and make your peanut butter oatmeal cookies as big as your heart desires!
