Equipment
- 12-cup muffin tin Standard size
- Paper muffin liners Or use cooking spray
- Large mixing bowl 2 needed — one for wet ingredients, one for dry
- Whisk
- Rubber spatula Or wooden spoon for folding batter
- Microplane zester / grater For zesting lemons
- Citrus juicer or reamer For juicing lemons
- Measuring cups and spoons
- Large cookie scoop or ice cream scoop For filling muffin cups evenly
- Wire cooling rack
- Small bowl For making the optional lemon glaze
- Oven thermometer (optional) Recommended to verify oven temperature accuracy
Ingredients
- 2 cups all-purpose flour 250g
- 2 tablespoons poppy seeds
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon fine salt
- ¾ cup granulated sugar 150g
- 2 tablespoons lemon zest From about 2 large lemons, packed
- 2 large eggs Room temperature
- ½ cup unsalted butter 113g, melted and slightly cooled
- ½ cup full-fat sour cream 120g, room temperature
- ¼ cup whole milk 60ml, room temperature
- 3 tablespoons fresh lemon juice From the same lemons you zested
- 1 teaspoon pure vanilla extract
For the Optional Lemon Glaze
- 1 cup powdered sugar 120g, sifted
- 2-3 tablespoons fresh lemon juice Adjust for desired consistency
Instructions
- Preheat your oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners or grease each cup generously with cooking spray, then set aside.
- Zest 2 large lemons using a microplane directly over a large mixing bowl to collect about 2 tablespoons of packed zest. Cut and juice the lemons, reserving 3 tablespoons for the batter and an extra 2–3 tablespoons if making the glaze.
- Add the granulated sugar to the bowl with the lemon zest and rub them together with your fingertips for 30–60 seconds until the mixture is fragrant and slightly yellow. This releases the lemon oils and amplifies the citrus flavor.
- To the lemon sugar, add the eggs, melted butter, sour cream, milk, 3 tablespoons lemon juice, and vanilla extract. Whisk until fully combined and smooth.
- In a separate large bowl, whisk together the flour, poppy seeds, baking powder, baking soda, and salt until evenly distributed.
- Pour the wet ingredients into the dry ingredients and fold gently with a rubber spatula until just combined — the batter should be thick and slightly lumpy. Do not overmix.
- Using a large cookie scoop, divide the batter evenly among the 12 prepared muffin cups, filling each nearly to the top for a tall dome.
- Bake at 425°F for 5 minutes, then — without opening the oven — reduce heat to 375°F (190°C) and bake for an additional 13–15 minutes, until the tops are golden and a toothpick inserted in the center comes out clean.
- Let the muffins cool in the tin for 5 minutes, then transfer them to a wire rack to cool for at least 10 more minutes before glazing or serving.
- Whisk together the powdered sugar and lemon juice in a small bowl until smooth, then drizzle over the warm muffins. Allow the glaze to set for 5–10 minutes before serving.
Notes
- Rub the lemon zest into the sugar with your fingertips before mixing — this is the single biggest flavor upgrade you can make in this recipe.
- Do not overmix the batter. Stir only until the flour just disappears; lumps in the batter are completely normal and desirable.
- Fill muffin cups nearly to the top for bakery-style domed tops. Combined with the high initial oven temperature, this is the key to a great rise.
- Use room temperature eggs, sour cream, and milk for a smoother batter that bakes more evenly.
- Full-fat sour cream is strongly recommended. Low-fat alternatives will result in drier, less tender muffins.
- Full-fat plain Greek yogurt can be substituted for sour cream in a 1:1 ratio with minimal difference in texture or flavor.
- Store cooled muffins in an airtight container at room temperature for up to 3 days, in the refrigerator for up to 5 days, or freeze for up to 3 months.
- To freeze, wrap each muffin individually in plastic wrap and place in a zip-top bag. Freeze unglazed and add fresh glaze after thawing for best presentation.
- To reheat from room temperature, microwave for 15–20 seconds. From frozen, thaw at room temperature for 1 hour or microwave for 30–45 seconds.
- For a blueberry variation, fold 1 cup of fresh or frozen blueberries into the finished batter before filling the cups. Do not thaw frozen blueberries before using.
