Bright, fluffy, and perfectly lemony! They're incredibly easy to make, soft and moist thanks to sour cream, and packed with real lemon flavor from both the juice and zest.
Preheat your oven to 425°F and line a 12-cup muffin tray with liners or use baking spray.
In a medium bowl, whisk the flour, poppy seeds, baking powder, and baking soda together.
In a large bowl, whisk the sour cream, sugar, oil, lemon juice, lemon zest, eggs, vanilla, and salt until smooth.
Pour the dry ingredients into the wet mixtures and mix until JUST combined.
Spoon the batter into the muffin liners to the very top.
Bake at 425°F for 5 minutes. Then reduce the heat to 350°F and bake for another 16–17 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the pan for 5 minutes, then brush the tops with fresh lemon juice.
