Step 1

Sift together flour, baking powder, sugar, and salt in a large bowl.

Step 2

Whisk together milk and egg in a small bowl. Add milk and egg mixture to flour mixture, whisking until blended. Stir in melted butter and lemon zest.

Step 3

Lightly oil a griddle and heat over medium-high heat. Fill a 1/4-cup measure with batter and pour onto the hot griddles. Drop a few blueberries on top and cover them with a little batter. Cook until bubbles form and the edges are dry, 3 to 4 minutes. Flip and cook until browned on the other side, 2 to 3 minutes. Repeat with remaining batter.
