Lemon Poppy Seed Loaf
Equipment
- 1 × 9×5-inch (23×13 cm) loaf pan
- 2 × mixing bowls (medium and large)
- 1 × Hand mixer or stand mixer
- 1 × rubber spatula
- 1 × whisk
- 1 × cooling rack
- 1 × zester or grater
- Measuring Cups and Spoons
Ingredients
For the Lemon Poppy Seed Loaf:
- 1 ¾ cups 225 g all-purpose flour, sifted
- 1 teaspoon baking powder
- ½ teaspoon salt
- ¾ cup 175 g unsalted butter, softened (not melted)
- ¾ cup 165 g granulated sugar
- 3 large eggs
- 2 tablespoons fresh lemon juice
- Zest of 2 lemons
- 2 tablespoons poppy seeds
- ¾ cup 175 ml milk
For the Lemon Glaze (Optional):
- 1 tablespoon lemon juice
- 1 cup 120 g powdered sugar, sifted
- 3 teaspoons milk
Instructions
- Prepare the Baking Pan: Lightly grease a 9×5-inch (23×13 cm) loaf pan with softened butter or a thin layer of vegetable oil. For extra assurance against sticking, you can also line the bottom with parchment paper. Set the pan aside while you prepare the batter.
- Preheat the Oven: Set your oven to 350°F (180°C) and allow it to fully preheat. This ensures even baking and helps the loaf rise properly without becoming dense.
- Combine Dry Ingredients: In a medium mixing bowl, sift the flour to eliminate clumps and create a light texture. Whisk in the baking powder and salt until evenly distributed. Keep this dry mixture aside for later use.
- Cream Butter and Sugar: In a large bowl or the bowl of a stand mixer, place the softened butter (not melted) and sugar. Beat on low to medium speed until the mixture becomes pale, fluffy, and creamy. This process incorporates air, which helps create a light loaf.
- Add the Eggs: Crack the eggs into a small bowl, lightly beat them with a fork, then add them to the butter-sugar mixture one at a time, mixing well after each addition. This gradual process prevents the batter from curdling and ensures a smooth consistency.
- Add Lemon Flavor and Poppy Seeds: Mix in the fresh lemon juice, lemon zest, and poppy seeds. These ingredients give the loaf its signature citrusy brightness and subtle crunch. Stir just until evenly combined, without overmixing.
- Alternate Wet and Dry Mixtures: With the mixer running on low speed, add half of the flour mixture followed by half of the milk. Blend until just incorporated. Repeat with the remaining flour and milk.
- Transfer Batter and Smooth: Pour the batter into the prepared loaf pan. Use a spatula to spread it evenly and smooth the top so it bakes uniformly. Tap the pan gently on the counter to release any trapped air bubbles.
- Bake the Loaf: Place the pan on the center rack of the preheated oven. Bake for 50–55 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Baking times may vary slightly depending on your oven.
- Cool the Loaf: Remove the pan from the oven and allow the loaf to cool in the pan for about 10 minutes. Carefully loosen the edges with a butter knife, then transfer the loaf to a cooling rack. Let it cool completely before glazing.
- Prepare the Glaze (Optional): In a small bowl, whisk together the powdered sugar, lemon juice, and milk. Adjust the milk quantity to reach a thick but pourable consistency. The glaze should coat the loaf without running off completely.
- Glaze and Serve: Spoon or drizzle the glaze over the cooled loaf, letting it slowly drip down the sides. Allow the glaze to set for 15–20 minutes before slicing. Serve plain or with a hot cup of tea or coffee for the perfect treat.
Notes
- Always use softened butter (not melted) to achieve a light, fluffy texture.
- Sifting the flour helps keep the loaf soft and prevents dense crumbs.
- Add eggs gradually to prevent curdling and maintain a smooth batter.
- Fresh lemon juice and zest make the flavor bright—avoid bottled juice for best results.
- Allow the loaf to cool fully before glazing so the topping sets properly.
- The glaze is optional but adds an extra tangy sweetness that pairs beautifully.
- Every oven varies, so check for doneness with a toothpick before removing.
Chef’s Secrets for Perfect Texture
The secret to this loaf’s soft, moist crumb lies in the creaming process.
Be sure to beat the butter and sugar until they are fully light and fluffy—this step incorporates tiny air bubbles that expand in the oven and give the loaf its tender texture.
Another chef’s trick is alternating between adding dry and wet ingredients.
This keeps the batter smooth, prevents lumps, and avoids overdeveloping the gluten, which can make the loaf tough.
Finally, don’t skip the zest—while juice gives acidity, it’s the zest that delivers the most concentrated lemon flavor.
Serving Suggestions Made Simple
This loaf is versatile and can be enjoyed in many ways.
Slice it thick and serve warm with a pat of butter for a cozy breakfast, or enjoy it plain with a cup of tea or coffee in the afternoon.
For a lighter dessert, pair slices with a dollop of Greek yogurt or fresh berries.
Hosting a brunch?
Cut it into smaller pieces and serve alongside fruit salad and savory bites—it adds a refreshing, citrusy touch to the spread.
If you prefer less sweetness, skip the glaze and enjoy the loaf on its own with a light dusting of powdered sugar.
Best Practices for Storage
To keep your lemon poppy seed loaf fresh, allow it to cool completely before wrapping.
Store it tightly wrapped in plastic wrap or in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate it for up to one week, though be sure to bring it to room temperature before serving for the best texture.
The loaf also freezes beautifully—wrap individual slices or the entire loaf in plastic wrap, then foil, and freeze for up to 3 months.
Thaw overnight at room temperature before enjoying, and glaze only after thawing for the freshest look and taste.
Frequently Asked Questions
1. Can I make this loaf ahead of time?
Yes! This loaf actually tastes even better the next day as the lemon flavor deepens. Bake it the night before, let it cool, and store it wrapped until ready to serve. Add the glaze just before serving for best presentation.
2. What if I don’t have poppy seeds?
You can simply omit them and still enjoy a flavorful lemon loaf. Alternatively, try adding chia seeds for a similar texture boost.
3. Can I use bottled lemon juice instead of fresh?
Fresh lemon juice is strongly recommended since bottled juice often tastes flat or slightly bitter. The zest is also essential, so fresh lemons are best.
4. How do I know when the loaf is fully baked?
Insert a toothpick into the center of the loaf. If it comes out clean or with only a few moist crumbs, the loaf is ready. Avoid overbaking, as it can dry out the texture.
5. Can I make this recipe dairy-free?
Yes, you can substitute the butter with a dairy-free margarine or plant-based butter alternative, and use almond or oat milk instead of regular milk. The flavor and texture will still be delicious, though slightly different.
