Preheat the oven to 350°F (175°C) and line a muffin tin with parchment liners.
In a blender or food processor, combine cottage cheese, eggs, maple syrup, almond milk, and vanilla extract. Blend until smooth.
In a large mixing bowl, whisk together oat flour, baking powder, baking soda, and salt.
Pour the blended wet ingredients into the dry ingredients. Gently fold until just combined.
Fold in the chocolate chips, reserving a handful for topping.
Divide the batter evenly among the muffin cups, filling each about three-quarters full. Sprinkle reserved chocolate chips on top.
Bake for 18-20 minutes or until a toothpick inserted into the centre comes out clean.
Let the muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
