I originally published this recipe in 2018 and have since made this many times and they’re always a hit. These and chocolate chip pudding cookies are my go-to cookies for any occasion.
You can’t beat the combination of chocolate and peanut butter. It’s why peanut butter blossoms, peanut butter cup cookies, and healthy buckeyes are so popular.
Today’s gluten-free flourless oatmeal cookies rival any of those classics, yet they don’t have any butter, flour, or oil. The peanut butter and oats together create cookie magic. They’re perfectly soft and chewy on the edges, and gooey on the inside!

Ingredients You Need
Here are the simple ingredients for these flourless peanut butter oatmeal cookies. Skip to the recipe card for exact measurements.
- Rolled oats: use certified gluten-free rolled oats, like Bob’s Red Mill, to keep them gluten-free, like I use in banana baked oatmeal. If you only have quick oats, try these no bake chocolate oatmeal cookies.
- Peanut butter: don’t use drippy peanut butter with the oil on top or the cookies will spread too much.
- Brown sugar: for sweetness and chewy texture. I haven’t tried it, but coconut sugar likely works too.
- Eggs: provide structure and binds the ingredients. Room temperature eggs are best.
- Baking soda: reacts with the brown sugar to help them rise.
- Semi-sweet chocolate chips: chocolate chunks are great too. Use dairy-free chocolate chips like Enjoy Life or Hu Kitchen if needed. They’re my go to for triple chocolate muffins or chocolate pudding cookies.
How to Make Flourless Oatmeal Peanut Butter Cookies
Here are the simple steps, with photos, to make these flourless oatmeal cookies with peanut butter. Skip to the recipe card for the printable version.
Step 1. Wet Ingredients. Beat the peanut butter, sugar, eggs, and vanilla together.
Step 2. Dry Ingredients. Stir in the oats and baking soda until combined.
Step 3. Add Chocolate Chips. Stir in your favorite chocolate chips or chocolate chunks. This is optional!
Step 4. Chill the Dough. Cover and refrigerate for at least 30 minutes, but up to 3 hours is ideal.
Step 5. Scoop the Dough. Use a large cookie scoop to scoop out the dough onto a parchment lined baking sheet.
Step 6. Bake. Bake the oatmeal cookies at 350 for 8-10 minutes, until the edges and tops are just set.
Expert Tips
- Don’t use cold peanut butter. It will be too difficult to stir into the cookie dough. Room temperature peanut butter and eggs are best for easy mixing.
- Opt for a traditional peanut butter like Jif or Skippy for the best cookie texture, but natural peanut butter you need to stir will work in a pinch. Be sure to stir it well.
- Add a few extra chocolate chips to the top of the cookie dough balls before baking to make them look extra pretty. I do this with oatmeal chocolate chip muffins too!
- It’s always best to choose certified gluten-free rolled oats if you have a sensitivity or are celiac. Oats are naturally gluten free, but can be packaged in a facility with gluten.
- Don’t over bake the cookies. They should barely look done when you pull them out of the oven. The edges will be wet but the tops should look glossy. It’s a tip I use for brown butter chocolate chip cookies too!
- Use parchment paper to line the pan and do not grease it or your cookies will spread.
Recipe FAQs
Yes, you can make these cookies with almond butter and they’ll turn out very similar to flourless almond butter cookies. You could also use any other nut or seed butter like cashew butter or sunflower seed butter.
I prefer the finished texture and shape of these cookies when I use a non-drippy peanut butter like Jif or Skippy. You can use natural peanut butter, but make sure the oil is mixed in really well and don’t forget to chill the dough. Expect a slightly different texture and shape than the ones you see in the photos.
Storage and Freezing
Store baked cookies in an airtight container at room temperature for up to 1 week or in the freezer for up to 3 months.
To make the dough in advance, cover and refrigerate the dough for up to 3 days. To freeze the dough, scoop it dough out into cookie dough balls, flash freeze for 30 minutes on a cookie sheet, then transfer to an airtight container and freeze for up to 3 months. Bake from frozen and add 1-2 minutes to the cook time.

Omg! These are amazing! I had to bake for 10 min. It’s definitely worth the wait to let them sit on the baking sheet for at least 8 min.
