Why Make No Sugar Oatmeal Cookies?

  • Easy to make: Minimal ingredients and mostly pantry staples, these cookies come together in only 40 minutes.
  • No added sugar: No maple syrup, honey, coconut sugar or low glycemic healthier sugars. 
  • Special diet approved: No eggs, dairy or wheat and when using gluten free oats, these are both vegan and gluten free oatmeal cookies.
  • Eat any time of the day: Made with wholesome ingredients these are perfect for breakfast, snack or even dessert! 
  • Freezer friendly: Make a big batch and store in the freezer when you need a healthy snack on the go! 

These sugar free oatmeal cookies turn out super soft, but not chewy like chocolate chip cookies or snickerdoodles. What makes cookies chewy is the sugar melting when baked. Sugar free cookies can’t be chewy, period.

Ingredients for Sugar Free Oatmeal Cookies

  • Flax eggs: These sugarless cookies are vegan. Flax egg add extra healthy fats and make us eat less animal products. If you want to use eggs, use 3 large eggs (and omit flaxseed and water).
  • Bananas: Make sure you use very ripe bananas (think black spots). This is true for most baked goods that contain bananas.

Have spotty black bananas but not ready to use them yet? Store them peeled or unpeeled in the freezer, then later just defrost and use them in your favorite healthy banana recipes!

  • Coconut oil: What are cookies without some sort of butter?! I used buttery flavoured coconut oil which I just got from Nutiva. I was curious and it worked so well! Coconut oil would work just fine or use vegan butter like Earth Balance.
  • Oats: These cookies are truly gluten free and are a flourless oatmeal cookies. No traditional whole wheat or white flour here.

How to make your own oat flour: While you can buy oat flour at the grocery store these days, it can still be hard to find and can often cost more especially if you need gluten free. A budget friendly way to make your DIY oat flour is to just grind oats to a fine powder in your blender or food processor, then sift. Use leftover oat flour to make healthy oatmeal muffins!

  • Trail mix cookies: Use what you love. I use peanuts, cashews and dates. When I am out of dates I make sugar free oatmeal raisin cookies. Dried fruit makes cookies sweeter. Just make sure you are not using sweetened dried fruit. I think sunflower seeds, Brazilian nuts, hazelnuts and unsweetened dried cranberries would all go so well in these cookies.
  • Baking essentials: Vanilla extract, cinnamon, baking soda and salt.

There is a full recipe card below. 

These healthy trail mix cookies are so simple to make!

  • Prep: Get your oven ready by preheating to 350 degrees F. Line a baking sheet with unbleached parchment paper or use a silicone mat and spray with cooking spray.
  • Make “eggs”: Whisk together the flaxseed and water in a small bowl. Let the mixture sit for 10 minutes.
  • Combine wet ingredients: Mix melted coconut oil, vanilla, cinnamon, baking soda and salt. Add in the flaxseed mixture and whisk well.
  • Add dry ingredients: Add oats and oat flour and mix well. Don’t be surprised that your dough will come out pretty thick.
  • Add trail mix: Throw in nuts and dried fruit and stir.
  • Form cookies: Scoop cookie batter onto baking sheet using a large ice cream scoop or a cookie scoop (a large tablespoon works too!). Flatten with the back of the scoop or a large spoon. Don’t worry, these cookies will not spread out more during baking.
  • Bake: Bake for 20 minutes. Then remove from the oven and let the cookies cool for a minute before transferring to a wire rack. Let them cool completely.

Optional Add-In’s and Variations

  • Vegan egg: If you do not have flaxseed, you can substitute 3 eggs or use chia seed egg.
  • Butter: I used buttery flavoured coconut oil. You can also use regular butter or vegan buttery spread like Earth Balance.

Whatever coconut oil or butter you use, keep in mind that it needs to be melted!

  • Mix-ins: Mini chocolate chips or dark chocolate chips (just remember this will change the sugar amount!), unsweetened dried cranberries, chopped dried apricots, dried cherries, blueberries or even crystalized ginger.
  • Shredded coconut: Unsweetened dried coconut flakes.
  • Nuts and seeds: Pumpkin seeds, chopped walnuts or pecans, pistachios, chia seeds, flax seeds or sunflower kernels. Unsalted is best! I love walnuts in healthy carrot cake baked oatmeal.
  • Warm spices: Swap cinnamon for gingerbread spice or apple pie spice or a combination of cinnamon, nutmeg, cloves, ginger or allspice.
  • Lemon or orange zest: Just a 1/4-1/2 teaspoon will add a delicious flavor.
  • Extract: Swap vanilla for pure almond extract for a nutty taste.
  • Applesauce: I have not tested using applesauce for the bananas, but it may work. Start at 1/2 a cup and use up to 1 cup. I would not substitute pumpkin though, as ‘mashed fruit’ is what gives these their sweet natural taste.
  • Peanut butter: Just a small amount (otherwise you will upset the balance of wet to dry ratio of ingredients) you could use a small amount of peanut butter powder.

Tips for Best Results

  • Chop dried fruit: If using ‘larger’ dried fruit, apricots, dates or even prunes chop them into dried raisin sized pieces.
  • Do not substitute flour: Oat flour is lighter than wheat flours, and if you substitute you will be using too much ‘regular’ flour which could lead to dry or crumbly cookies.
  • Mix-in amounts: No matter what mix-ins you use (either recipe as written or add-in variations) be sure to use only 1 cup total! 
  • Flatten the cookies: These cookies need some help to ‘spread’ out. Flatten them slightly to ensure they bake all the way through.
  • Cool for only 1 minute on the pan: After baking, cool for 1 minute on the pan to ensure the cookie holds shape, then move to a baking rack. Leaving them longer on the pan, might ‘bake’ them longer and your cookies might be over baked!

Are oatmeal cookies healthy?

That really depends on your definition of healthy! This recipe for sugar free oatmeal cookies are great for those looking for a no added sugar, gluten free, vegan cookie.

Are these diabetic oatmeal cookies?

While these cookies do not contain any added sugar, they do contain carbs from the oats/oat flour. While oats are considered nutrient dense and are absorbed slower by the body than wheat, it is probably best to check with your nutritionist/doctor if you are following a strict diet.

Are these low carb cookies?

Again, this depends on your ‘carb’ intakes and what you consider low carb. Net carbs of these trail mix cookies with no added sugar is 27 carbs. You may consider that a safe low carb range for a snack!

Why are my sugar free cookies not soft and chewy?

As I mentioned above, sugar free cookies will not be chewy because it is sugar that causes cookies to be soft as it melts while baking. These cookies will be soft, but not chewy.

Are sugar free cookies really sugar free?

I don’t want to mislead you- these cookies do have naturally occurring sugars from the banana and dates. When baked goods are labeled ‘sugar free’ this means they have no added sugar, artificial sweeteners or sugar alcohols. I love that these cookies are made with ‘real ingredients’ without any added sugar!

How to Serve Sugar Free Cookies?

How to Store Flourless Oatmeal Cookies?

Storing: It is best to place these cookies in a cool, dry open container. I don’t recommend storing in an airtight container or the cookies will get soggy.

Freezing: In an airtight container for up to 3 months. Thaw on the counter for a few hours.

Shipping? I would ship cookies only to a short destination where a receiver can pick up parcel immediately. 5 days in transit max. I recommend to place cookies in a ventilated container big enough to fit all cookies but so they don’t tumble in it and break.

    I made these cookies with 3 eggs and large flake oats. My cookies looked very different from your pictures but still tasted great. Could you tell me what measure of mashed banana the recipe needs.
    My batter was runnier than yours and I was hesitant to add more oat flour in case I disturbed the chemistry of the cookie. I will try the flax egg version and use quick oats next time I make these. Thanks for a great healthy cookie!

  2. Hi there,

    Please, please let your readers know that they must buy gluten free oats or gluten free oat flour to make these cookies! Organic or not, oats are not gluten free, so you have to buy gluten free oats. They are good, and taste the same. Thank you.

  3. 5 stars
    I love these cookies. I used the 3 eggs substitute version but it ended up being a bit too wet so I added another 1/2 cup flour and they were perfect. I used regular unbleached flour instead of oat flour as I didn’t have enough oats for grinding. Delivered! Love recipes with no added sugars!

    1. You could try, oat bran is a bit more dense, so you might start with 1/2 of what is called for in oat flour and adjust from there.

  4. They taste great, but mine did not bind together super well. Can anyone tell me what I might have done wrong? I thought maybe more flour?

  5. 5 stars
    I make these for my grandchildren and husband – I can not make enough- the way you explain everything is wonderful and the recipes always turn out so well. I am a proficient cook but enjoy your recipes immensely especially as I can convert into metric as I’m in UK. Thank you Olena.
