These healthy oatmeal cookies are thin, crispy and flavored with blueberries. They are easy to make and you only need four ingredients to make them. The cookies don’t require any flour, eggs, or dairy butter.
With blueberries in season, I wanted to create a blueberry version of my crispy oatmeal cookies. Making a crispy cookie when working with fresh blueberries is a little difficult because the juices from the blueberries will usually make cookies soft, but I was finally able to combine fresh berries with crispy cookies and I love the result.
Ingredients
- Quick Oats
- Peanut Butter
- Maple Syrup
- Blueberries
Quick oats: You can use quick oats or rolled oats. I like using quick oats because you don’t need to process them as long since they are already smaller than rolled oats.
Peanut butter: Make sure to use natural peanut butter with no added oils. Only peanuts and salt should be in the ingredients. Peanut butter can be substituted with natural almond butter.
Maple syrup: The cookies are lightly sweetened with pure maple syrup. Maple syrup also helps to thicken the dough and firm up the cookies.
Blueberries: You can use fresh blueberries or dried blueberries. If using fresh blueberries make sure they are ripe and sweet. If you don’t have fresh blueberries, you can use dried blueberries instead. Dried blueberries are actually much easier to work with for this recipe but as I discussed above, I really wanted to create the cookies with fresh blueberries because I love the flavor and texture that baked blueberries add to desserts. I don’t recommend using frozen blueberries because they have too much moisture.
I like making the cookies with fresh blueberries because the blueberry juices spread into the cookie, giving you blueberry flavor throughout. However, there are a lot of advantages with working with dried blueberries. You can add more dried blueberries and not worry about the juices causing the dough soften. You can also store the dried blueberries version for longer.

How to Make Crispy Blueberry Oatmeal Cookies
- The quick oats are first pulsed in a food processor until they become small crumbs and start to partially become flour. This finer consistency is what gives the cookies their crispy texture.
- The peanut butter and maple syrup are then mixed in until a cookie dough forms.
- The blueberries are cut in half and are gently folded in. You don’t want to crush the berries too much because it will make your dough too wet.
- Use a 1.5 tablespoon cookie scoop to scoop the dough. Each dough ball needs to be flattened to a round disk that is about 1/4 inch thick. The cookies are then baked for about 15 minutes.
Cookie Texture and Sweetness
These are meant to be healthy crispy cookies. They are crispy but are not super crunchy. The cookies are also only lightly sweetened.

4 Ingredient Crispy Blueberry Oatmeal Cookies
Ingredients
- 3/4 cup (70 g) quick oats
- 6 tbsp (96 g) natural peanut butter
- 2 tbsp (30 ml) maple syrup
- 1/4 cup (41 g) fresh blueberries or dried blueberries
Instructions
- Preheat oven to 350°F (177°C). Line a large cookie sheet with parchment paper or silicone baking mat.
- Add quick oats to a food processor. Pulse oats until they become very small and fine and start to partially become flour consistency. See photo in post for reference. I pulsed mine on high for about 30 seconds. If you are unsure if your oats are fine enough, it's better to pulse them a little longer. The smaller they are, the crispier the cookies will be.
- Add oats, peanut butter and maple syrup to a large mixing bowl. Make sure you scrape the food processor and get all of the oat powder that sticks to the sides into your bowl. Make sure to also scrape all the maple syrup into your bowl as well as a lot of it gets stuck to the measuring spoon or measuring cup. Mix with a spatula until the ingredients are fully and evenly incorporated and the dough thickens to the consistency of cookie dough.
- If using fresh blueberries, wash and thoroughly pat them dry. Cut them in half. Gently fold them into the dough with your spatula. It will be a little difficult because the dough is firm but just do your best not to crush the berries too much and fold them so they are evenly distributed throughout the dough. If using dried blueberries, just add them directly in (no need to cut them) and fold them into the dough.
- Using a 1.5 tbsp cookie scoop, scoop dough onto the prepared cookie sheet, spacing the dough balls about 2 inches apart. Use the back of a metal spoon to flatten the dough balls into round disks and smooth the edges. You want the cookies to be fairly thin, between 3/16 inch to 1/4 inch thick. The cookies do not spread much during baking, so shape them as you want the final outcome to be. Try your best not to squish the fresh berries too much because you don't want the dough to get too wet. If your dough is too sticky, you can wet the spoon before using it to flatten and shape.
- Bake cookies for 13-15 minutes or until the surface and edges are brown. The browner the cookies are, the crispier they will be so try to bake until they are light or medium brown all over but be careful not to let the edges get too dark. Let cookies cool completely on the baking sheet before trying to remove them. They will crisp up further as they cool. Cookies with fresh blueberries are best enjoyed right away but leftovers can be stored in the freezer. Cookies with dried blueberries can be stored at room temperature for a few days and longer in the freezer.
Notes
- I like using fresh blueberries in baking but it is a little tricky to keep these cookies crispy with fresh blueberries. Make sure you don't add too many blueberries because it will make the dough too soft and wet. You also do need to cut them in half because the berries will not release their juices during baking if you keep them whole. If you don't have fresh blueberries or don't want to deal with using fresh blueberries, this recipe also works with dried blueberries.
- Because these cookies are only lightly sweetened, make sure to use sweet blueberries.
- Make sure to use natural peanut butter with no added oils. Regular peanut butter with added oils will not work.
- The estimated nutrition is calculated using fresh blueberries.

Hi – can we add raisins to replace fresh blueberries in this recipe?
We have not tested this recipe with raisins but you can use dried blueberries which are similar! Let us know if you give it a try!
Can you substitute butter for the peanut butter? I’m allergic to peanuts, do that would be the only way I could make these.
No you can’t substitute with butter but the recipe works with almond butter
