This lemon poppy seed loaf offers a delightful balance of zesty citrus and crunchy poppy seeds. Made with a tender crumb enhanced by Greek yogurt or sour cream, it’s finished with a smooth lemon glaze that adds a tangy sweetness. Simple steps mix the all-purpose flour, baking agents, fresh lemon zest and juice with softened butter and sugar to create a moist batter. After baking until golden and fluffy, the glazed loaf cools for perfect slicing. A satisfying treat that brightens any gathering with fresh lemon flavor.
The smell of lemons being zested always pulls me back to my grandmother's kitchen, where she'd teach me to grate just enough to catch the bright oils without hitting the bitter pith underneath.
I made this for a friend's birthday brunch last spring, and before I could even get the glaze poured, people were hovering around the counter asking what smelled so incredible.
Ingredients
- 1 1/2 cups all-purpose flour: The foundation that gives structure to all that moisture
- 2 tbsp poppy seeds: These tiny seeds create texture that keeps every bite interesting
- 1 tsp baking powder: Helps the loaf rise tall and proud
- 1/2 tsp baking soda: Works with the acidic ingredients for extra lift
- 1/4 tsp salt: Balances sweetness and enhances all the flavors
- 1/2 cup unsalted butter softened: Room temperature butter creams properly for tender texture
- 1 cup granulated sugar: Sweetens while creating a tender crumb structure
- 2 large eggs: Bind everything together and add richness
- 1/2 cup Greek yogurt or sour cream: The secret ingredient that keeps this loaf incredibly moist
- Zest of 2 lemons: Fresh zest brings essential oils that bottled lemon juice cannot replicate
- 1/4 cup fresh lemon juice: Provides tang and reacts with baking soda for lift
- 1 tsp vanilla extract: Rounds out the bright lemon with warmth
- 1 cup powdered sugar: Creates that perfect pourable glaze consistency
- 2-3 tbsp fresh lemon juice: Adjust to get your ideal glaze thickness

My aunt now requests this for every family gathering, and honestly, it has become the one recipe I can make without even looking at the measurements anymore.
Room Temperature Ingredients Matter
I learned the hard way that cold butter and eggs will not cream properly, leaving you with a dense loaf instead of that tender crumb we are after.
Zesting Technique
Use a microplane and rotate the lemon as you zest, catching only the bright yellow part and avoiding the white pith underneath which turns bitter.
Glaze Consistency
Start with 2 tablespoons of lemon juice and add more only if needed, because you want the glaze thick enough to stay put but thin enough to pour beautifully.
- If your glaze is too thick, add juice one teaspoon at a time
- If too thin, whisk in more powdered sugar gradually
- Pour the glaze slowly back and forth across the loaf for even coverage
This loaf keeps beautifully for days, somehow managing to taste even better on the second day.
