Preheat oven to 400°F. and line or grease a 24-cup mini muffin tin.
In a large bowl whisk together dry ingredients: flour, sugar, baking powder, sea salt, and cinnamon. Add in melted coconut oil, mashed banana, and oat plant based beverage. Fold in berries. Divide the batter between the 24 muffin cups.
Bake mini muffins for 20 to 22 minutes, or until toothpick inserted into the center comes out clean. Remove muffins from oven and let sit in tin for 5 minutes to cool. Gently remove muffins from muffin tin and let cool on a baking rack.
