Lemon Poppy Seed Loaf

The kitchen smelled absolutely divine when my grandmother first taught me to make this lemon poppy seed loaf. I was maybe twelve years old, standing on a step stool to reach the counter, watching her zest lemons with such practiced ease. That bright citrus scent became my definition of comfort baking, something I still chase every time I preheat the oven.

Last summer, I made three loaves in one weekend because my neighbor mentioned she loved lemon anything. I wrapped one in parchment and twine, left it on her porch, and received the most heartfelt text message an hour later. Sometimes food is just the easiest way to say someone matters.

Ingredients

• 1 ½ cups (190 g) all-purpose flour: The foundation that gives structure while staying tender, dont pack it down when measuring
• 1 tbsp poppy seeds: These tiny black seeds add subtle crunch and a beautiful speckled appearance throughout the loaf
• 1 tsp baking powder: Helps the loaf rise with a gentle lift, creating that perfect domed top
• ¼ tsp baking soda: Works with the acidic lemon juice to create extra tenderness in the crumb
• ¼ tsp salt: Just enough to enhance all the flavors without making it taste salty
• ½ cup (115 g) unsalted butter, softened: Room temperature butter incorporates perfectly for that tender melt in your mouth texture
• 1 cup (200 g) granulated sugar: Sweetens the loaf while helping create a golden crust and moist interior
• 2 large eggs, room temperature: Essential for structure and richness, bring them to room temp first for better incorporation
• ⅓ cup (80 ml) whole milk: Adds moisture and richness, though low fat works in a pinch
• ⅓ cup (80 ml) sour cream or plain yogurt: The secret ingredient that makes this loaf exceptionally moist and tender
• Zest of 2 lemons: This is where all the bright lemon flavor comes from, zest before juicing for easier handling
• ¼ cup (60 ml) fresh lemon juice: Adds tangy brightness and activates the baking soda for tenderness
• 1 tsp pure vanilla extract: Rounds out all the flavors and adds that classic baked good depth
• ½ cup (60 g) powdered sugar: For the optional glaze that adds sweetness and a beautiful finishing touch
• 1 to 2 tbsp fresh lemon juice: Thin the glaze to your desired consistency, thinner for drizzling, thicker for spreading

Instructions

Get your oven and pan ready:

Preheat your oven to 350°F (175°C) and grease a 9x5 inch loaf pan, lining the bottom with parchment paper for easy removal later.

Whisk the dry ingredients together:

In a medium bowl, combine the flour, poppy seeds, baking powder, baking soda, and salt, whisking until everything is evenly distributed.

Cream the butter and sugar:

Beat the softened butter and granulated sugar in a large bowl for 2 to 3 minutes until the mixture looks pale and fluffy.

Add the eggs one at a time:

Beat in each egg separately, making sure the first is fully incorporated before adding the second.

Mix in the wet ingredients:

Combine the lemon zest, lemon juice, vanilla, milk, and sour cream until smooth.

Combine wet and dry mixtures:

Gradually add the dry ingredients to the wet mixture, mixing just until you no longer see visible flour.

Prepare for baking:

Pour the batter into your prepared pan and smooth the top with a spatula.

Bake to perfection:

Bake for 45 to 55 minutes until a toothpick inserted in the center comes out clean or with just a few moist crumbs.

Cool before glazing:

Let the loaf rest in the pan for 10 minutes, then move it to a wire rack to cool completely.

Make the optional glaze:

Whisk powdered sugar with fresh lemon juice until smooth, then drizzle over the completely cooled loaf.

Save

This loaf has become my go to for new neighbors and office birthdays alike. There is something universally appealing about lemon baked goods that feels like sunshine in bread form.

Getting the Most Lemon Flavor

I have learned that zest carries the essential oils where most of the lemon flavor lives, so do not skip it. Roll your lemons on the counter before zesting to release those oils, and zest before you juice the lemons, it is so much easier to handle a whole fruit.

Perfecting the Texture

The sour cream or yogurt is what makes this loaf exceptionally moist compared to other quick breads. Greek yogurt works beautifully if that is what you have, and honestly, I have used plain kefir in a pinch with great results.

Storage and Serving Suggestions

This loaf keeps well for three days at room temperature, wrapped tightly in plastic or stored in an airtight container. The flavors actually develop more after the first day, so it is even better tomorrow than today.

• Try toasting a slice and adding a pat of butter for breakfast
• Serve alongside afternoon tea with a friend who needs cheering up
• Freeze individual slices wrapped in plastic for emergency dessert cravings

Save

Every slice brings back those kitchen memories with my grandmother, though I think my version has finally caught up to hers. Happy baking, and may your kitchen always smell like lemons.
