Preheat oven to 350°F. Line a baking sheet with silicone baking mat.
In a medium bowl, add banana and mash thoroughly with a spoon until it turns into a puree consistency with no chunks of banana left. Stir in almond flour until thoroughly combined and a dough forms. The dough should feel wet but not too sticky. If you touch it with your finger, the dough should not stick to it. If your dough is too sticky, you can add a little more almond flour.
Using a 1.5 tbsp cookie scoop, scoop cookie dough and place onto prepared baking sheet, spacing the dough balls 2 inches apart. Use the back of a spoon or the palm of your hand to press down gently on the dough balls until they form round disks about 3/8 inch thick.
Place cookies into oven and bake about 15-25 minutes or until the edges are golden brown. The surface of the cookies should also be slightly firm. Let cookies cool on baking sheet before removing. Cookies will be initially crispy on the outside and soft on the inside if eaten within a few hours after they are baked. After that, they will be soft and cakey all over. The cookies will be sweeter and have a stronger banana flavor the next day, similar to banana bread.
Notes
These cookies are meant to be low sugar. If you want a sweeter cookie you can add 1 tbsp of maple syrup or add chocolate chips.
To add more flavor to these cookies, you can add chocolate chips or a little cinnamon.
For a nut-free version, you can try my 2 ingredient banana oatmeal cookies linked in the post.
Cookies should be stored in an airtight container. They will keep around 2 days at room temperature and longer in the fridge or freezer.
