Preheat your oven to 180°C (350°F).
Lightly grease a baking sheet to prevent sticking, and set it aside for later use.
In a large mixing bowl, combine the sweetened applesauce, oats, peanut butter, and cinnamon.
Stir the mixture well until all ingredients are thoroughly combined and you have a cohesive dough.
Using your hands, form the dough into 12 equal-sized balls.
Place each ball on the prepared baking sheet.
Press each ball down gently to flatten into a cookie shape.
Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the cookies are firm around the edges.
Remove the cookies from the oven and allow them to cool completely on the baking sheet or transfer them to a wire rack.
