Preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius) and line a baking sheet with parchment paper.
In a large mixing bowl, whisk together the rolled oats, protein powder, cinnamon, baking soda, and salt.
In a separate medium bowl, whisk together the almond butter, applesauce, egg, and vanilla extract until smooth.
Combine the wet and dry ingredients, stirring until a cohesive dough forms.
Fold the raisins into the mixture using a spatula.
Portion the dough into 12 equal-sized balls and place them on the prepared baking sheet.
Gently flatten each dough ball with the palm of your hand as the cookies will not spread significantly.
Bake for 8 to 10 minutes until the edges are firm and slightly golden.
Cool on the baking sheet for 5 minutes before transferring to a wire rack.
