Preheat the oven to 350 degrees. To begin, measure out a cup of oats and blend in a food processor or high speed blender to create oat flour. Measure a cup of this flour and add to a large bowl.
Add the oats, baking soda, cinnamon, and coconut sugar (if using). Stir to combine.
In a small bowl, combine the almond butter, liquid stevia (if using), plant milk, and vanilla.
Add the wet ingredients to the dry ingredients and stir well.
Add the chocolate chunks, chocolate chips, or raisins and stir to combine.
Place a sheet of parchment paper over the cookie sheet and scoop batter onto the cookie sheet. This batter will make 12 small or 6 large cookies. Flatten slightly with your fingers if necessary. Bake for 8-10 minutes.
Let cool for five minutes, then transfer to a cookie rack to cool fully.
These cookies are great served warm with a big glass of ice cold plant milk or with coffee or tea. They also work well crumbled and used in my Sugar Free Banana Pudding (just omit the chocolate chips and add an extra 1/4 cup coconut sugar).
