Preheat the oven to 350 degrees Fahrenheit.
In a medium bowl, mix together the oat flour, whole oats, flax, salt, baking powder and cinnamon.
In a separate small bowl whisk the eggs until well combined. Add the coconut oil, maple syrup, applesauce and vanilla extract, whisking to combine. It’s okay if the coconut oil solidifies a bit.
Add the wet ingredients to the dry ingredients, stirring until well combined. Add the berries and stir gently to just combined, trying not to break the berries up too much.
Spoon heaping tablespoons of the dough onto 2 greased baking sheets, using your fingers to flatten each cookie.
Bake for 12 minutes or until lightly golden brown. Remove from the oven and allow to cool.
Serve the cookies immediately, store in an airtight container, or freeze for breakfasts or snacks. To freeze, place a piece of parchment or plastic wrap in between each cookie so they don’t stick together, then seal in an air-tight container or freezable bag for up to a month in the freezer. Defrost or gently reheat prior to serving.
