These Lemon Poppy Seed Muffins are bright, fluffy, and wonderfully lemony. They’re simple to make using sour cream and fresh lemon juice. Instead of a glaze, the tops are brushed with extra lemon juice after baking for a burst of fresh citrus flavor.

About This Recipe
I’d been planning to make lemon poppy seed muffins for a long time. When I finally gathered the ingredients I found two unopened bags of poppy seeds in my spice drawer—expired, but still there. I bought new ones anyway since I wanted to share the muffins with others.
These turned out even better than I expected: soft, tender, and perfectly lemony. The sour cream keeps the crumb moist, while a final brush of lemon juice on the hot muffin tops adds a clean, bright finish.
Key Ingredients

All-purpose flour: Fluff the flour, then spoon and level it into the measuring cup to avoid packing too much in.
Poppy seeds: Adds the classic crunch and visual specks to these muffins.
Baking powder and baking soda: Baking soda reacts with the lemon juice for an initial lift while baking powder helps them rise fully in the oven.
Sour cream: Replacing milk with sour cream makes these extra moist. Plain yogurt can be used as an alternative.
Vegetable oil: Keeps the crumb tender and moist.
Fresh lemon juice and zest: Both juice and zest are used for concentrated lemon flavor. I brush the tops with additional lemon juice after baking for brightness.
Eggs: For structure and moisture.
Vanilla extract: Adds warmth and depth to the citrus notes.
Salt: Enhances all the flavors.
Instructions

STEP 1: In a medium bowl, whisk together the flour, poppy seeds, baking powder, and baking soda.

STEP 2: In a large bowl, whisk the sour cream, sugar, oil, lemon juice, lemon zest, eggs, vanilla, and salt until smooth.

STEP 3: Add the dry ingredients to the wet ingredients and mix until just combined. Avoid overmixing to keep the muffins tender.

STEP 4: Spoon the batter into the liners, filling each cup to the top for a tall dome.

STEP 5: Bake at 425°F for 5 minutes, then reduce the oven to 350°F and bake another 16–17 minutes, or until a toothpick inserted in the center comes out clean. Let the muffins cool in the pan for 5 minutes, then brush the tops with fresh lemon juice to brighten the flavor.
