Here is a giant healthy cookie recipe with no added sugar and whole food ingredients!
I started making these sugar free oatmeal cookies back in 2018 when we hiked with small kids and I was extremely passionate about healthy eating. Not that I am not anymore, but as kids grew I became more understanding with “balance and moderation”.:)
Why You’ll Love This Recipe
- No added sugar: No maple syrup, honey, coconut sugar or low glycemic sugar substitutes. Fruit is the only sweetener!
- Easy to make: Minimal ingredients and mostly pantry staples, these cookies come together in only 40 minutes.
- 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 a healthy 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!
Ingredients for Sugar Free Oatmeal Cookies
To make sugar free oatmeal cookies recipe you will need common pantry staples plus bananas.
- Bananas: Make sure you use very ripe bananas with many black spots to ensure sweet cookies.
- Flaxseed and water: Flax eggs keep this recipe vegan, add extra healthy fats and help to eat less animal products.
- Oats: I prefer to use rolled oats or also known as old-fashioned oats. You can use quick oats but cookies will have less chewy texture.
- Oat flour: You can use store-bought oat flour or here is a quick tutorial on DIY oat flour. Don’t use just ground up oats, they have to be sifted.
- Coconut oil: I tried this recipe with both coconut oil and Nutiva buttery flavored coconut oil. Both worked great! I think vegan butter like Earth Balance will be fine too but I am not sure how recipe will work with oil that you can’t melt.
- Nuts: Use whichever nuts you love. I use peanuts, almonds and cashews. I think sunflower seeds, Brazilian nuts, pecans and hazelnuts will go well.
- Dates: You can use regular dates or Medjool dates.
- Baking essentials: Vanilla extract, cinnamon, baking soda and salt.
How to Make Sugar Free Oatmeal Cookies
These sugar free oatmeal cookies are so simple to make! There is also a full recipe card below.
- Prep wet ingredients: In a small bowl, whisk together flaxseed and water, and let the mixture sit for 10 minutes. In another large bowl, mash bananas and add 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 cookie dough will come out pretty thick. Throw in chopped nuts and dried fruit, 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 cookies 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.
Tips for Best Results
- Follow the recipe: For best results, I recommend to follow this cookie recipe as written. Baking is truly a science!
- Chop dried fruit: If using larger dried fruit like apricots, dates or even prunes, chop them into dried raisin sized pieces. Also raisins or dried cranberries will work, no need to chop them. Just make sure you are not using sweetened dried fruit.
- Do not substitute flour: Oat flour is lighter than wheat flours and if you substitute it, your cookies will turn out dry or crumbly.
- 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 dry!
Additions and Variations
No matter what mix-ins you use, either as written or with add-in variations, be sure to use only 1 cup total.
- 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 will work.
- Shredded coconut: Unsweetened dried coconut flakes.
- Nuts and seeds: Pumpkin seeds, chopped walnuts or pecans, pistachios, chia seeds, flax seeds or sunflower seeds. Unsalted is best!
- Warm spices: Swap cinnamon for gingerbread spice, pumpkin 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 extract for pure almond extract for a nutty taste.
- Peanut butter: Add just 1-2 tablespoons otherwise you will upset the balance of wet to dry ratio of ingredients. You could also use a small amount of peanut butter powder.
How to Store
Store: It is best to place sugar free oatmeal cookies in a cool, dry ventilated or partially closed container. I don’t recommend storing in an airtight container or the cookies will get soggy.
Freeze: Place in a freezer 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. For 5 days in transit maximum.
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.
FAQs
I have not tried this swap, so can’t vouch for results. You will need to skip flaxseed and water and try to add 2 large eggs. That’s what seems to work out for some readers. Please let me know how cookies turn out.
I don’t recommend it. Bananas are quite unique, binding and make the base of this recipe. Maybe pumpkin puree or applesauce will work.
I have not tested this recipe with any oil that you can’t melt like avocado oil, olive oil etc. A reader made these cookies with grapeseed oil and they turned out well.
Dried fruit makes cookies sweeter. If you are OK with not sweet cookies, you can omit dates.
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.

- In a small bowl, whisk flaxseed and water. Let sit for about 10 minutes while you are getting other ingredients ready.
- In a large bowl, mash bananas. Add coconut oil, vanilla extract, cinnamon, baking soda and salt. Add flaxseed mixture and whisk really well.
- Add oats and oat flour; stir to combine. Add nuts and dried fruit; mix well. Dough will be very thick.

Yumm
Awesome idea on the bar cookie! Glad you enjoyed it!

Thanks so much!

Hi, you could add a small amount of nut butter or hemp seeds! Protein powder will be too absorbent, but you could try protein cookie recipe.
I’m diabetic and can’t wait to try these plz send me more recipes Thanks
Glad to have you here Janine! Feel free to browse through all our healthy recipes on the site!
Forgot to star the recipe!
Thank you Tina! Glad you enjoyed them!
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!
It will be between 1/2 – 3/4 cup.
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.
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!
So glad it turned out great Vicki! Thanks for sharing your substitutions!
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?
You could try another flax egg and be sure your dried fruit and nuts are small even pieces.
This looks like a great recipe! So you know if pay fiber can replace oat flour?
Never used one so won’t be able to tell.
