Preheat oven to 180°C (360°F) and line a baking sheet with parchment paper.
In a large mixing bowl add egg, applesauce, almond butter, maple syrup, ground cinnamon, vanilla extract and salt. Using a hand mixer or whisk, stir the wet mixture for a couple of minutes until all is well combined.
Add to the wet mixture rolled oats, oat flour and baking powder. Using a spatula stir all ingredients together.
Optionally, mix in additional ingredients such as chocolate chips or walnuts.
Let the dough rest in the fridge for at least 10 minutes.
Scoop about 1/3 cup of dough out and shape 10 cookies. Transfer the raisin cookies to the parchment paper covered baking sheet, spacing them apart.
Bake in hot oven for 10 to 12 minutes. Let cool over a baking rack before serving.
