Ingredients

Find the full ingredient list, with measurements, in the recipe card below.

  • Oats – Our preference is to use rolled oats. Be sure to look for certified gluten-free oats on the label for celiac disease concerns.
  • Coconut sugar – This is our favorite less refined granulated sugar. You could also substitute light brown sugar.
  • Baking soda – To assist in browning the cookies.
  • Baking powder – Helps the cookies rise and adds a light texture.
  • Fine sea salt – A pinch of salt is a key ingredient to tie all of the ingredients together.
  • Protein powder – This helps hold the cookies together in place of flour. We recommend using a clean protein powder such as Ora brand So Lean So Clean because is free from any toxic ingredients.
  • Melted coconut oil – This adds moisture to the dough and helps to keep the cookies from drying out while they bake. Melted butter can also be used.
  • Egg –  Eggs act as a binding agent, which is especially important with gluten-free recipes such as this one. Don’t have eggs on hand? Check out these 11 egg substitutes.
  • Plain Greek yogurt -This adds more moisture and a creamy texture.
  • Chocolate chips – We like to use dark chocolate, but semi-sweet, milk chocolate, and even white chocolate chips all work well.

Expert tip

Cookies can go from underbaked to overbaked quickly. Start with the recommended baking time of 10 minutes and watch for the edges to turn golden brown.

The centers may still look slightly undercooked when you remove them from the oven, but they will continue to cook on the hot baking sheet.

Recipe variations

  • Melt some chocolate and drizzle it over the cookies for an extra layer of sweetness and a touch of elegance.

FAQS

Are flourless oatmeal cookies gluten-free?

Typically, yes. Oats are naturally gluten-free, but cross-contamination can be a concern. To ensure they’re gluten-free, use certified gluten-free oats or oats specifically labeled as such.

Can I make these cookies with steel-cut oats?

Steel-cut oats have a different texture and cooking time compared to rolled oats. While it’s possible to use them, they may result in a very different cookie texture, so it’s not recommended for a traditional flourless oatmeal cookie.

Storage tips

Store these cookies in an airtight container for up to a week.

Freeze them in an airtight resealable freezer bag for 2-3 months.

    I wanted to make a treat for my neighbor who has been under the weather, and who is also gluten free. So happy I found this recipe! Its a wonderful healthy twist on a favorite cookie. She and her kids loved the cookies, and no one guessed they were a healthy upgrade!

  3. 5 stars
    These Flourless Oatmeal Cookies are a game-changer! These gluten-free delights are a sweet and chewy sensation, and the chocolate chips take them to the next level. Easy to make, even easier to devour. A cookie masterpiece!

  4. 5 stars
    Fantastic! I replaced honey with sugar and added some vanilla and some protein powder and they were fantastic! The protein powder also helps them stay together a little better

    1. Great suggestion! I actually happen to have some protein powder. I’m trying this for sure. Thanks Dean!

  5. Yeah, I agree with Jenny Fish – no competition on chocolate v. raisins! I mean, from a purely healthy perspective: raisins. But, c’mon: chocolate wins, hands-down! Actually, my solution would probably be to go half-and-half (I’ve always been the one to seek happy compromise!). These look fantastic – gorgeous, gorgeous photos! Mmmmm … I’m sitting here with my coffee wishing this is what I will eat for breakfast in a few minutes (I mean, there’s oats and egg and yogurt …) 😀

  6. Chocolate v. Raisins is not even a real competition. Chocolate all the way! I just wanted to know that I love your blog. People tend to make recipes and cooking super complicated, but I like your short and simple ingredient list and instructions. I plan on making that granola this weekend!
