Last week blueberries were on sale. And they were not the usual blueberries: they were humongous, huge, XL juicy blueberries.

Why are these oatmeal cookies healthy?
Unlike the cookies you buy, these blueberry oatmeal cookies are rich in nutrients and fibers. Furthermore, this recipe is also dairy-free, oil-free and gluten-free, if you use gluten-free rolled oats.
As these are blueberry cookies made with oats, they also have a low glycemic index. Nutritionists and dietitians suggest eating low glycemic index foods for a healthier lifestyle because they will keep your glucose levels under control. Meaning that your energy levels will stay constant throughout the entire day!
The ingredients
This healthy blueberry oatmeal cookie recipe is very simple. It only requires eight basic ingredients, no flour, no oil and no butter. What is more, with the right substitutes these cookies can also become vegan.
Keep on reading to learn all the ingredients you need, their substitutes and more details!
- Rolled oats: for the best blueberry cookies, I recommend making this recipe with rolled oats (also known as “old-fashioned” oats), gluten-free if necessary. Although also quick oats or a mix of both will work, the texture of your cookies won’t be the same. For high protein blueberry cookies, you can replace part of the oats with protein powder- keep on reading for more details!
- Coconut sugar: for healthier oat cookies, this recipe uses coconut sugar. But if you don’t have it, you can replace with brown sugar, date sugar, normal sugar or any other granular sweetener of your choice. Syrups and honey, instead, are not adequate as they will alter the cookie dough texture. For sugar-free cookies, I recommend making these blueberry oatmeal cookies with erythritol.
- Almond butter: the creamy almond butter can be replaced with cashew butter. As they both have a sweet delicate taste, I find that almond butter and cashew butter are the best options for making blueberry oat cookies. On the contrary, peanut butter is too intense and does not really match with the blueberries. For nut-free blueberry oat cookies, this recipe can also be prepared with sunflower seed butter or tahini.
- Egg: for the best taste and nutritional benefits I recommend using a fresh egg, from free range chicken if possible. If you want to make vegan cookies, replace with one flaxseed egg.
- Baking powder: this ingredient will help your cookie rise. However, if you don’t have it or prefer not to use it, the baking powder can be left out. This recipe will come out anyway, but the blueberry cookies will be slightly flatter.
- Vanilla flavor: although it is just a teaspoon, this ingredient will add a delicious taste to your banana cookies.
- Lemon juice: for the best taste, I encourage squeezing the juice of a fresh lemon. Nevertheless, for more convenience you are free to use the lemon juice in the bottle.
- Salt: this enhances the tastes and balances the sweetness.
- Blueberries: although both fresh and frozen blueberries work, I recommend making these healthy oatmeal cookies with fresh blueberries. First, they are juicer and tastier than the frozen ones. Second, they are less likely to smash and make your dough wet.
Oatmeal cookies with protein powder
There are two ways to make high protein blueberry oatmeal cookies. The first option is to replace part of the oats with protein powder. In this case, my recommendation is to substitute 50 grams of oats with protein, no more. The second option, instead, is to enrich this recipe with a scoop of protein powder and adjust the dough with more almond butter or milk until it reaches the right consistency.
Keep in mind that different types of protein powder behave differently when baking. Thus, you may need to adapt the dough accordingly.
As a rule of thumb:
- Vegan protein powder and casein are more absorbent. Therefore your recipe will likely require a pour of milk (if it is too thick).
- Whey protein powder mixes very well and dissolves easily. Therefore you may need to adjust the dough with more oats.
With respect to the flavor, my recommendation is to use vanilla or unflavored protein powders. Other flavors, instead, may taste too artificial and spoil the flavor of your protein blueberry oat cookies.
And if you are still looking for high protein oatmeal cookies, I recommend checking this recipe here. It is very similar to this one, but with the addition of protein powder.
Oatmeal protein cookies
Say goodbye to flat and dry protein cookies. These are soft, chewy and irresistibly delicious oatmeal protein cookies! Sugar-free and oil-free, these oat cookies are also very healthy.
How to make vegan blueberry oatmeal cookies
Do you follow a vegan diet but still want to make these cookies? No problem, because making vegan blueberry oatmeal cookies is very easy. All you have to do is substituting the egg with one flaxseed egg (or any other egg replacement). The preparation of one flaxseed egg is as simple as mixing 1 tablespoon of ground flaxseeds with 2 ½ tablespoons of water. Let it rest for about five minutes and you are set to bake!
How to make oatmeal cookie with blueberry
In a large mixing bowl add 1 egg, almond butter, coconut sugar (or any granular sweetener you like), vanilla extract, lemon juice and salt. Using a fork or whisk, stir the wet mixture for a couple of minutes until all is well combined.
Add to the wet mixture the rolled oats, optionally the protein powder, and the baking powder. Using a spatula, stir all ingredients together. Depending on the nut butter consistency, the dough may require about 1 tablespoon (15 ml) of additional milk if it is too thick.
Finally, fold in the blueberries, making sure not to smash them. Let the healthy blueberry oatmeal cookie batter rest in the fridge for at least 15 minutes.
Scoop some dough out and shape 10 cookies. Transfer the blueberry cookies to a parchment paper covered baking sheet, spacing them apart. Bake in hot oven for 10 to 14 minutes and let cool over a baking rack before serving.

Tips for the best blueberry cookies with oats
Do you want to learn how to make the best healthy blueberry oatmeal cookies? Then keep on reading because I'm about to give you a couple of tips.
- Make these healthy blueberry cookies with rolled oats. Your cookies will have a better texture and they won’t get soggy as it would happen with quick oats.
- Use creamy almond butter or cashew butter, as they mix significantly better than crunchy nut butters.
- Make sure you use a granular sweetener, as liquid options will ruin the dough. If erythritol, xylitol, coconut sugar or brown sugar all work, maple syrup or honey won't.
- Don’t forget the pinch of salt. Even though it is just a pinch, it will balance the sweetness and bring all the flavors out.
- For the best blueberry oat cookies, feel free to add some extra ingredients. Dark chocolate chips, white chocolate chips, almonds, pumpkin seeds...Whatever you crave, the sky's the limit!
- Before shaping the cookies, let the dough rest in the fridge for at least 15 minutes. This will ensure a firmer dough and therefore better oatmeal cookies with blueberries
- When forming your cookies, make thicker "discs". We don’t want flat oatmeal cookies, do we?!
