Preheat the oven to 350°F (175°C) and lightly grease a muffin tin.
In a large mixing bowl, combine the rolled oats, cottage cheese, almond milk, honey (or maple syrup), vanilla extract, baking powder, cinnamon, and salt. Mix well until all ingredients are combined.
Gently fold in the blueberries, being careful not to crush them.
In a separate bowl, beat the eggs and then add them to the oat mixture, stirring until fully incorporated.
Spoon the mixture evenly into the prepared muffin tin, filling each cup about 3/4 full.
Bake for 25-30 minutes, or until the tops are golden and a toothpick inserted in the center comes out clean.
Allow the oat cups to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
