01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a large bowl, whisk together the rolled oats, flour, baking soda, baking powder, cinnamon, and salt until evenly distributed.
03 - In a separate bowl, blend the melted coconut oil with the packed brown sugar until smooth. Stir in the applesauce, plant-based milk, and vanilla extract.
04 - Pour the wet mixture into the dry ingredients and stir until just combined. Do not overmix.
05 - Gently fold the raisins into the dough until evenly dispersed.
06 - Lightly mash the blueberries and blackberries together with a fork. If using frozen berries, thaw and drain excess liquid first, then pat dry with a paper towel to avoid excess moisture.
07 - Drop small spoonfuls of the mashed berries onto the dough and fold gently 2 to 3 times to create a swirl effect. Do not overmix or the color will become uniform.
08 - Using a cookie scoop or tablespoon, portion dough onto the prepared baking sheets, spacing about 2 inches apart.
09 - Bake for 12 to 14 minutes until edges are golden and centers are just set.
10 - Allow cookies to rest on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely.
