Preheat your oven to 350°F (175°C) to ensure even baking and a perfect golden brown color.
In a large mixing bowl, whisk together the eggs, unsweetened applesauce (or mashed banana), almond butter, and pure maple syrup until smooth and well combined.
In a separate bowl, mix the quick oats, ground cinnamon (if using), and sea salt until evenly distributed.
Gradually add the dry ingredients to the wet mixture, stirring until the dough is thick and slightly sticky.
Fold in your choice of add-ins such as chocolate chips, nuts, dried fruits, or seeds to customize your cookies.
Using a spoon or cookie scoop, drop tablespoon-sized portions of dough onto a parchment-lined baking sheet, leaving space between each cookie.
Bake for about 10-12 minutes, or until the cookies are lightly golden on the edges. Watch carefully to avoid over-baking.
Remove from the oven and let cookies cool on the baking sheet for a few minutes before transferring to a wire rack. Enjoy warm or store for later!
