Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners.

In a large bowl, whisk together the flour, baking powder, and sugar until combined.

In another bowl, mix the cottage cheese, eggs, milk, and vanilla extract until smooth.

Fold the wet ingredients into the dry ingredients gently; then add the blueberries and mix carefully to avoid overmixing.

Divide the batter evenly among the muffin cups, filling each about two-thirds full.

Bake for 20-25 minutes or until golden brown and a toothpick comes out clean.
