Preheat your oven to 350°F (180°C). Line a baking sheet with parchment paper.
If you don't have almond flour you can make oat flour by blending rolled oats in a food processor until it reaches a fine, flour-like consistency.
In a mixing bowl, combine the almond, peanut butter, mashed banana, vanilla extract and cinnamon. If desired, add honey or maple syrup to sweeten the dough. Adjust the sweetness according to your baby's preference. Stir until you have a cohesive cookie dough.
Stir until you have a cohesive cookie dough. If the dough is too sticky, sprinkle a little more flour. If its too dry add more mashed banana.
Scoop small portions of the dough and shape them into small cookies. Place the cookies on the prepared baking sheet with some space between each. Gently flatten with a fork to create ridges. The dough might be sticky so dip the fork in water when making the ridges.
Bake in the preheated oven for about 10-12 minutes, or until the edges are lightly golden. Keep an eye on them to prevent over-baking. They might be soft at first, but they will evenly firm up.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Once cooled, serve these delicious and baby-friendly peanut butter cookies to your little one. Remember to supervise them while eating to ensure safe consumption.
