Preheat oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners.
In a large bowl, whisk together flour, sugar, baking powder, and salt.
In a separate medium bowl, whisk together Greek yogurt, vegetable oil, eggs, and vanilla extract until smooth.
Gently stir the wet ingredients into the dry ingredients until just combined; do not overmix.
Fold the blueberries carefully into the batter.
Divide the batter evenly among the muffin cups, filling each about three-quarters full.
Bake for 18 to 22 minutes, or until a toothpick inserted into the center comes out clean.
Allow muffins to cool in the tin for 5 minutes before transferring to a wire rack.
