These lemon poppy seed muffins are soft, buttery breakfast muffins made with fresh lemon zest and juice, sour cream, and 3 tablespoons of poppy seeds, finished with a thin lemon glaze. The recipe makes 12 muffins in about 35 minutes at 375°F.
Most of the lemon flavor comes from one small step: rubbing the zest of two lemons into the sugar with your fingertips before anything else goes in.

- Makes: 12 standard muffins, one 12 cup tin
- Time: 15 minutes prep, 18 to 22 minutes baking, then cooling before the glaze
- Oven: 375°F (190°C)
- Lemons: 2 cover the whole recipe. Zest both for the batter; you need about 4 tablespoons of juice, 2 for the batter and 2 for the glaze.
- Poppy seeds: 3 tablespoons in 2 cups of flour
- Dairy: ¾ cup sour cream or Greek yogurt plus ¼ cup milk
- Glaze: 1 cup powdered sugar, 2 tablespoons lemon juice, 1 to 2 teaspoons milk if needed
Rubbing Lemon Zest Into the Sugar
Put the ⅔ cup of sugar in a bowl, zest both lemons straight over it, and rub the two together with your fingertips for a minute. The sugar turns pale yellow, damp, and smells strongly of lemon. The sugar crystals scrape the oils out of the zest, and those oils carry far more lemon flavor than the juice does.
Zest only the yellow skin. The white pith underneath is bitter, and in a mild muffin you will taste it.
Use fresh lemons for the juice as well. Bottled juice tastes flat next to fresh zest. If you love this flavor pairing, the same zest and seed combination runs through my lemon poppy seed cake.
Dry Ingredients, Butter, and the Dairy
Whisk the flour, baking powder, baking soda, salt, and poppy seeds together so the seeds are spread evenly. There is a full tablespoon of baking powder for height but only ½ teaspoon of baking soda. More soda would leave a bitter, soapy edge.
Taste a few poppy seeds before they go in. They are oily and go rancid in the pantry, and stale seeds taste bitter. I keep mine in the freezer.
Whisk the lemon sugar with the melted butter, then add the eggs, sour cream, milk, lemon juice, and vanilla and whisk until smooth. Let the butter cool to lukewarm and use room temperature eggs. Hot butter can scramble the eggs, and cold eggs make melted butter set into small lumps.
I have made these with both sour cream and Greek yogurt. Sour cream gives a more tender crumb; yogurt makes it a little firmer and tighter. Either works, as long as it is full-fat.
Pour the wet mixture into the dry ingredients and fold just until no dry flour shows. The batter should be thick but not stiff. If you have made my easy blueberry muffins, the texture will feel familiar.
How to Get Tall Bakery-Style Domes
Bakery muffins look tall because the batter is thick and the cups are full. This batter is already thick, so do not thin it with extra milk. Use a cookie scoop and fill each liner about three-quarters full for 12 muffins.
If you want taller, rounder tops, divide the same batter among 10 cups instead. Bake them 2 to 3 minutes longer and go by the toothpick, not the clock.
Bake at 375°F for 18 to 22 minutes, starting to check at 18. The edges should be light golden and a toothpick in the center should come out clean. Leave the muffins in the pan for 5 minutes so the crumb sets, then move them to a rack.
How Thick Should the Lemon Glaze Be?
Whisk 1 cup of powdered sugar with 2 tablespoons of lemon juice, then stir in the teaspoon of zest if you are using it. It should be thick enough to fall from a spoon in a slow ribbon that sits on the surface for a few seconds before it smooths out. Too thick to drizzle? Add milk ½ teaspoon at a time, up to 2 teaspoons.
Drizzle it over muffins that are completely cool. On warm muffins the glaze melts and soaks in, and you end up with sticky tops instead of a thin white shell. Give it about 20 minutes to set.
When Lemon Muffins Taste Bitter or Bake Dense
- Bitter aftertaste: white pith in the zest, stale poppy seeds, or extra baking soda. Zest lightly, taste the seeds, and measure the soda level.
- Dense, tough crumb: the batter was overmixed. Fold only until the flour disappears; a few lumps are fine.
- Greasy streaks or lumps in the batter: the eggs or dairy were cold when they met the melted butter. Let them sit out for 30 minutes first.
- Weak lemon flavor: the zest went straight into the batter or the juice was bottled. Rub the zest into the sugar and use fresh lemons.
- Glaze disappeared: the muffins were still warm. Wait until they are cool to the touch on the bottom.
Glazing Ahead and Storing
These taste best the day they are baked. If I bake the night before, I leave them unglazed in an airtight container and glaze in the morning. Glazed muffins keep at room temperature for 1 day, then go in the fridge.
To freeze, wrap the unglazed muffins and freeze them; thaw at room temperature, warm briefly in a toaster oven if you like, and glaze once they are cool. Glaze does not freeze well; it turns wet and patchy as it thaws.
Quick Answers for Lemon Muffin Bakers
Can I make lemon poppy seed mini muffins?
Yes. Fill a mini muffin tin three-quarters full and bake at 375°F for about 10 to 12 minutes, until a toothpick comes out clean. Glaze them once cool.
Can I make them gluten free?
I have had good results with a cup-for-cup gluten free flour blend swapped in for the all-purpose flour. I avoid almond flour here because it competes with the lemon.
Can I use oil or coconut oil instead of butter?
Melted coconut oil works, but the muffins lose some of the richness the butter gives. I stick with butter for this recipe.
Can I make them with orange instead?
Yes. Use orange zest and juice in the same amounts for a sweeter, warmer citrus muffin. For another orange bake, try my cranberry orange muffins.
For more lemon and poppy seed baking, the lemon poppy seed cupcakes use the same citrus base with a softer crumb, the lemon poppyseed mini bundt cakes make a good gift, and cardamom poppy seed cookies sit nicely next to these on a brunch table. For a plain everyday batch, my sour cream muffins are the simpler cousin. Save this recipe to your muffin board for the next time you have two lemons on the counter.
Lemon Poppy Seed Muffins Recipe
These lemon poppy seed muffins are soft, buttery muffins made with fresh lemon zest and juice, sour cream or Greek yogurt, melted butter, and poppy seeds, finished with a simple lemon glaze. The recipe makes 12 bakery-style muffins in about 35 minutes at 375°F, with a tender, moist crumb and a light crunch from the seeds. The key step is rubbing the zest of 2 lemons into the sugar before mixing, which releases the lemon oils and gives the muffins a strong lemon flavor. Serve these lemon and poppy seed muffins for breakfast, brunch, Easter, or with afternoon tea. Glaze them only once cool. Unglazed muffins can be made the night before or frozen, and glazed muffins keep 1 day at room temperature.
Ingredients
- FOR THE MUFFINS
- 2 cups all-purpose flour
- 1 tablespoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 3 tablespoons poppy seeds
- ⅔ cup granulated sugar
- Zest of 2 lemons
- ½ cup unsalted butter, melted and cooled
- 2 large eggs, room temperature
- ¾ cup sour cream or Greek yogurt
- ¼ cup milk
- 2 tablespoons lemon juice
- 1 teaspoon pure vanilla extract
- FOR THE LEMON GLAZE
- 1 cup powdered sugar
- 2 tablespoons lemon juice
- 1 teaspoon lemon zest (optional)
- 1-2 teaspoons milk (if needed for consistency)
Instructions
PREHEAT AND PREP: Preheat the oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or lightly grease each cup.
MIX DRY INGREDIENTS: In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, and poppy seeds until fully combined.
INFUSE THE SUGAR: In a separate bowl, combine the granulated sugar and lemon zest. Rub the zest into the sugar using your fingers until the mixture is fragrant and evenly combined.
COMBINE WET INGREDIENTS: In another bowl, whisk together the melted butter, eggs, sour cream, milk, lemon juice, and vanilla extract until smooth and well blended.
COMBINE WET AND DRY INGREDIENTS: Pour the wet mixture into the dry ingredients. Gently fold the batter together with a spatula just until combined, being careful not to overmix.
FILL THE MUFFIN CUPS: Divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
BAKE: Place the muffin tin in the preheated oven and bake for 18 to 22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
COOL: Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
PREPARE THE GLAZE: In a small bowl, whisk together the powdered sugar and lemon juice until smooth. Stir in the lemon zest and add milk as needed to reach a pourable consistency.
GLAZE THE MUFFINS: Once the muffins are fully cooled, drizzle the lemon glaze evenly over the tops of the muffins.
Notes
Use fresh lemons: 2 lemons give enough zest for the batter and about 4 tablespoons of juice for the batter and glaze. Zest only the yellow skin; the white pith is bitter. Rub the zest into the sugar until it smells strongly of lemon. Use room temperature eggs and let the melted butter cool to lukewarm so the batter stays smooth. Fold only until no dry flour shows. For taller bakery-style tops, divide the batter among 10 cups and bake 2 to 3 minutes longer. Glaze only fully cooled muffins. Store glazed muffins at room temperature for 1 day, then refrigerate. Freeze unglazed muffins and glaze after thawing. Sour cream gives a more tender crumb; Greek yogurt a slightly firmer one.
