Instructions
Here’s how to make your own batch of Banana Blueberry Oatmeal Cookies! Jump to the recipe card at the very bottom of this post for exact measurements, temperatures, and bake times.

Step One: Blend part of the oats into a coarse flour and transfer to a bowl.

Step Two: In the same bowl, stir mashed bananas, nut butter, vanilla, flaxseed, and chia until thickened.

Step Three: Add the remaining whole oats, almond flour, cinnamon, salt, and nuts; mix until evenly combined.

Step Four: Gently fold in the frozen blueberries.

Step Five: Scoop portions onto a lined tray, flatten slightly, then bake until golden at the edges.

Step Six: Let cookies rest briefly on the tray, then transfer to a rack to cool completely before serving or storing.

Storage
Let your cookies cool completely on a wire rack before storing to avoid sogginess. Then stack them with parchment paper in between in an airtight container: theyโll keep at room temperature for up to 3 days or in the fridge for about a week if you like them a bit firmer.
Expert Tips

Use ripe, spotty bananas for max sweetness and moisture- no extra sugar needed.
FAQ
Yes you can, fresh blueberries work fine too.
If your bananas arenโt sweet enough, mash them and let the mixture sit a few minutes to develop sweetness, or stir in a teaspoon of maple syrup or sugar if needed.
