Grease muffin cups or line with paper cups and set aside.
Preheat the oven to 400°F.
Combine flour, sugar, baking powder, and salt in a medium bowl and make a well in the center.
Combine beaten egg, milk, and oil in a small bowl.
Add the wet mixture all at once to the flour mixture.
Fold in blueberries and stir just until combined (do not overstir).
Spoon batter into prepared cups, filling each about two-thirds full.
Bake for 18 to 20 minutes or until golden and a toothpick inserted near the middle comes out clean.
Remove from muffin cups and let cool on a wire rack for 5 minutes.
