Method
- Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners or grease it lightly.
 - In a large bowl, combine 2 cups of flour, 1 cup of sugar, 1 tablespoon of baking powder, and 1/2 teaspoon of salt. Mix well.
 - In another bowl, whisk together the melted butter, egg, milk, lemon zest, lemon juice, and vanilla extract until smooth.
 - Pour the wet ingredients into the dry ingredients and stir until just combined. Do not overmix.
 - In a separate bowl, prepare the crumb topping by mixing 1/2 cup of flour, 1/4 cup of sugar, cubed butter, and cinnamon. Use a fork or your fingers to combine until crumbly.
 - Divide the muffin batter evenly among the muffin cups, filling each about 2/3 full. Sprinkle the crumb topping generously over each muffin.
 - Bake for 18–20 minutes or until a toothpick inserted into the center comes out clean.
 - While the muffins are baking, prepare the lemon glaze by whisking together 1 cup of powdered sugar, 2 tablespoons of lemon juice, and 1 teaspoon of lemon zest until smooth.
 - Once the muffins are done, allow them to cool for a few minutes in the pan before transferring them to a wire rack. Drizzle the lemon glaze over the warm muffins.
 
Notes
For an extra punch of lemon flavor, add a few drops of lemon extract to the batter. These muffins freeze beautifully — just skip the glaze, freeze, then add it after reheating. Serve slightly warm for the best texture.
