  • whisk
  • spatula or wooden spoon
  • wire rack
  • small bowl

Ingredients
  

Muffins

  • 1 ½ cups all-purpose flour (190g)
  • ¾ cup granulated sugar (150g)
  • 2 teaspoons baking powder
  • ¼ teaspoon baking soda
  • ¼ teaspoon salt
  • 2 tablespoons poppy seeds
  • 1 large egg at room temperature
  • ½ cup milk (120ml), at room temperature (whole or 2%)
  • ¼ cup unsalted butter (60g), melted and cooled
  • 1 tablespoon fresh lemon zest (from 1-2 lemons)
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon vanilla extract

Lemon Glaze

  • 1 cup powdered sugar (120g)
  • 2-3 tablespoons fresh lemon juice

Instructions
 

Preparation

  • Preheat the oven to 400°F (200°C) and prepare a 12-cup muffin tin by lining it with paper liners or greasing it.
  • In a large bowl, combine the flour, granulated sugar, baking powder, baking soda, salt, and poppy seeds.
  • In a separate bowl, whisk the egg. Then, rub lemon zest into the granulated sugar (from the dry ingredients), and add this lemon-infused sugar to the egg along with milk, melted butter, lemon juice, and vanilla extract; whisk until well combined.

Baking

  • Pour the wet ingredients into the dry ingredients and mix with a spatula or wooden spoon until just combined, being careful not to overmix.
  • Divide the batter evenly among the 12 prepared muffin cups.
  • Bake for 5 minutes at 400°F (200°C), then reduce the temperature to 375°F (190°C) and continue baking for 13-17 minutes more, or until a wooden skewer comes out clean.
  • Allow the muffins to cool in the tin for 5-10 minutes, then transfer them to a wire rack to cool completely.

Glaze

  • While muffins cool, whisk powdered sugar and fresh lemon juice in a small bowl until smooth; adjust lemon juice as needed for a pourable consistency.
  • Drizzle the glaze over the completely cooled muffins and let it set for a few minutes before serving.

Notes

Ensure all cold ingredients are at room temperature for a better muffin texture. Do not overmix the batter, as this can lead to tough muffins. For an extra lemony kick, add a touch more lemon zest to the glaze.
