Ingredients

Scale
  • 2 cups (240g) all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • ¾ cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 1 cup (240ml) buttermilk (or milk plus a splash of lemon juice or vinegar)
  • ⅓ cup (80ml) vegetable oil
  • Zest from 2 medium lemons
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons poppy seeds
  • For the Vanilla Bean Glaze:
  • 1 cup (120g) powdered sugar, sifted
  • Seeds scraped from 1 whole vanilla bean pod (or 1 teaspoon pure vanilla bean paste)
  • About 2 tablespoons fresh lemon juice
  • 1 teaspoon milk or cream (optional)

Instructions

  1. Preheat your oven to 375°F (190°C). Line your muffin tin with liners or grease it lightly.
  2. In a large bowl, whisk together all-purpose flour, baking powder, baking soda, salt, and granulated sugar until evenly combined.
  3. In a separate bowl, beat eggs until frothy. Add buttermilk, vegetable oil, fresh lemon juice, and lemon zest. Whisk gently until blended.
  4. Pour the wet ingredients into the dry mixture. Using a spatula, gently fold just until combined—some lumps are okay. Stir in poppy seeds.
  5. Use a spoon or small ladle to fill each muffin cup about ¾ full.
  6. Bake for 18–22 minutes. Check at 18 minutes by inserting a toothpick into the center; it should come out clean or with a few moist crumbs.
  7. Cool muffins in the pan for 5 minutes, then transfer to a cooling rack to cool completely before glazing.
  8. Make the vanilla bean glaze by whisking powdered sugar with vanilla bean seeds and fresh lemon juice in a small bowl. Add milk or cream if too thick.
  9. Drizzle the glaze over cooled muffins and let set for about 10 minutes before serving.

Notes

Avoid overmixing the batter to keep muffins light and fluffy. Use fresh lemon zest for best flavor. Glaze muffins when they are cool to prevent melting. Silicone liners help with easy muffin removal. For dairy-free, substitute buttermilk with almond or oat milk plus lemon juice and use coconut oil instead of vegetable oil.
