Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

For the loaf:

• 1 ½ cups all-purpose flour
• 2 tablespoons poppy seeds
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ¼ teaspoon salt
• ½ cup unsalted butter, softened
• ¾ cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 2 tablespoons lemon zest (from about 2 lemons)
• ¼ cup fresh lemon juice
• ½ cup plain Greek yogurt or sour cream
• ¼ cup milk (dairy or plant-based)

For the glaze:

• 1 cup powdered sugar
• 2 tablespoons lemon juice
• ½ teaspoon vanilla extract

Directions

1. Preheat oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
2. In a medium bowl, whisk together the flour, poppy seeds, baking powder, baking soda, and salt.
3. In a large bowl, cream together the softened butter and sugar until light and fluffy.
4. Beat in the eggs one at a time, then mix in the vanilla extract, lemon zest, and lemon juice.
5. Stir in the Greek yogurt and milk until the mixture is smooth.
6. Gradually add the dry ingredients to the wet mixture, mixing just until combined. Do not overmix.
7. Pour the batter into the prepared loaf pan and smooth the top.
8. Bake for 45–50 minutes, or until a toothpick inserted into the center comes out clean.
9. Allow the loaf to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
10. While the loaf cools, mix the glaze ingredients until smooth. Drizzle over the cooled loaf and let the glaze set before slicing.

FAQs

Can I use bottled lemon juice instead of fresh?

Fresh lemon juice is recommended for the best flavor, but bottled juice can be used in a pinch.

What can I use instead of Greek yogurt?

Sour cream or plain regular yogurt are suitable substitutes that maintain the moist texture.

Can I omit the poppy seeds?

Yes, the loaf will still be delicious without them, though you’ll lose some of the texture.

Why did my loaf sink in the middle?

This can happen if the batter is overmixed, the oven was too hot or too cool, or if underbaked. Ensure your oven temperature is accurate and test for doneness with a toothpick.

Can I use a different glaze?

Yes, a simple lemon glaze (just powdered sugar and lemon juice) or even a cream cheese frosting works well.

How do I zest lemons without a zester?

Use a fine grater or the smallest holes on a box grater, avoiding the bitter white pith.

Is this loaf very sweet?

It’s moderately sweet with a tart lemon balance. You can adjust the glaze or reduce sugar slightly if desired.

Can I add lemon extract for more flavor?

Yes, adding 1/2 teaspoon of lemon extract enhances the citrus flavor without altering texture.

What is the best way to ensure a moist loaf?

Use room temperature ingredients, avoid overmixing, and do not overbake. Greek yogurt or sour cream adds moisture and richness.

Can I bake this in a bundt pan?

You can, but you may need to double the recipe depending on pan size and adjust the baking time accordingly.
