Instructions
Preheat the oven to 400°F. Line a 12-cup muffin pan with paper liners or lightly grease the muffin cups.
In a large bowl, whisk together all-purpose flour, granulated sugar, baking powder, and salt.
In a large measuring cup, add vegetable oil and large egg. Add enough milk so the liquid reaches the 1-cup mark (approximately 1/3 to ½ cup milk total).
Add vanilla extract and lemon zest to the measuring cup and whisk until combined.
Pour the wet ingredients into the dry ingredients and stir gently with a fork until just combined. Do not overmix. The batter will be thick.
Fold in blueberries (about 1 cup) using a spatula or spoon.
Divide the batter evenly among the 12 muffin cups, filling each about halfway full.
Sprinkle the remaining granulated sugar evenly over the tops of the muffins.
Bake for 15–20 minutes, or until the tops are lightly golden and a toothpick inserted into the center comes out clean.
