Lemon Zucchini Muffins

Step 1
Preheat oven to 400 degrees F (200 degrees C). Grease 12 muffin cups, or line with paper muffin liners.

Step 2
Mix flour, 3/4 cup sugar, baking powder, baking soda, and salt in a large bowl; make a well in the center of the flour mixture. Mix zucchini, yogurt, butter, egg, 1 tablespoon lemon juice, and 1 tablespoon lemon zest in a separate bowl; pour yogurt mixture into well. Gently stir yogurt, slowly incorporating the flour mixture until just blended. Batter may be slightly lumpy. Pour batter evenly into prepared muffin cups.

Step 3
Bake in preheated oven until a toothpick inserted into the center of a cupcake comes out clean, about 20 minutes.

Step 4
While muffins are baking, whisk 1/3 cup lemon juice, 1/4 cup sugar, and 2 teaspoons lemon zest together in a saucepan over medium heat until mixture comes to a simmer and sugar is dissolved, about 5 minutes. Cover and keep glaze warm over low heat.

Step 5
Poke each muffin several times with a toothpick; spoon glaze over muffins. Cool in the pans for 10 minutes before removing to cool completely on a wire rack.
