Preheat the oven to 350°F (175°C) and line a 12-cup muffin tin with paper liners or grease it lightly.
In a large bowl, combine the cottage cheese, eggs, almond milk, honey, and vanilla extract. Mix well until smooth.
In a separate bowl, whisk together the oat flour, protein powder, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Do not overmix.
Divide the batter evenly among the 12 muffin cups.
Bake for 18 to 20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
Remove the muffins from the oven and allow them to cool in the pan for 5 minutes before transferring to a wire rack to cool completely.
