Preheat your oven to 350°F (175°C) to ensure even baking.
Line a baking sheet with parchment paper to prevent sticking and ease cleanup.
In a large mixing bowl, whisk together the almond flour, tapioca flour (if using), baking powder, baking soda, ground cinnamon, and lemon zest until well combined.
In a separate bowl, whisk the melted unsalted butter (or coconut oil), lightly beaten egg, pure maple syrup, and vanilla extract until smooth.
Pour the wet ingredients into the dry ingredients and stir gently until just combined, being careful not to overmix.
Gently fold in the fresh blueberries, keeping them whole for bursts of flavor.
Use a spoon or cookie scoop to drop tablespoon-sized dough portions onto the prepared baking sheet, leaving space between each cookie.
Press a few extra blueberries on top of each cookie for a beautiful presentation.
Bake the cookies in the preheated oven for 10-12 minutes, or until the edges are lightly golden.
Remove from oven and let cookies cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely. Enjoy warm or at room temperature!
