The Tenderest Lemon Poppy Seed Muffins
The first thing you notice isn't the poppy seed crunch—it's the way the lemon flavor lingers, bright and clear. These tender muffins come together in just 15 minutes of hands-on time and stay moist for days. The secret is a simple buttermilk soak for the poppy seeds.
Equipment
- 12-cup standard muffin tin
- Paper liners
- Microplane or fine zester
- Mixing bowls (medium and large)
- Whisk
- Rubber spatula
- Cookie scoop
Ingredients
For the Poppy Seed Soak
- 2 tablespoons poppy seeds
- 1/2 cup buttermilk
For the Muffin Batter
- 2 large lemons (zest only; juice reserved for optional glaze)
- 1 cup white sugar
- 1/2 cup unsalted butter, softened
- 2 large eggs, room temperature
- 1 1/2 cups all-purpose flour, spooned and leveled
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
Instructions
- Soak the poppy seeds: In a small bowl, combine poppy seeds and buttermilk. Stir and let sit while you prepare the rest of the batter.
- Preheat oven: Preheat to 375°F (190°C). Line a 12-cup muffin tin with paper liners.
- Zest and rub: In a large bowl, combine sugar and lemon zest. Rub together with your fingertips until the sugar is pale yellow and intensely fragrant, about 1 minute.
- Cream butter and sugar: Add softened butter to the lemon sugar. Beat with a whisk or electric mixer until pale and fluffy, about 3 minutes.
- Add eggs: Beat in eggs one at a time, scraping down the bowl after each addition.
- Combine dry ingredients: In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
- Alternate wet and dry: Add half the flour mixture to the butter mixture and fold gently. Add the buttermilk-poppy seed mixture and fold. Add the remaining flour and fold just until the last streak of flour disappears. Do not overmix.
- Fill liners: Divide batter evenly among the prepared muffin cups, filling each about 2/3 full. A cookie scoop works best for even muffins.
- Bake: Bake for 18–20 minutes until the tops are golden and a toothpick inserted in the center comes out clean. Let cool in the tin for exactly 5 minutes, then transfer to a wire rack to cool completely.
- Optional glaze: Whisk 1 cup powdered sugar with 2 tablespoons fresh lemon juice until smooth. Drizzle over cooled muffins.
