Light and lemony poppy seed muffins offer a delicate crunch and bright citrus flavor. These bakery-style muffins are a delightful addition to any brunch spread.
Preheat the oven to 350°F and line a muffin pan with paper liners for even baking.
In a large bowl, whisk together all-purpose flour, baking powder, baking soda, salt, and poppy seeds until evenly combined.
In a separate bowl, beat eggs, granulated sugar, melted butter, milk, vanilla extract, and lemon zest until smooth and well mixed.
Gently fold the wet ingredients into the dry mixture, taking care not to overmix to preserve a tender crumb.
Divide the batter evenly among 8 muffin cups, filling each about 3/4 full for optimal rise.
Bake for 20–23 minutes, rotating the pan halfway through, until the tops are golden and a toothpick inserted in the center comes out clean.
Let muffins cool in the pan for 5 minutes before transferring to a wire rack to prevent sogginess on the bottom.
