How to Make Lemon Poppy Seed Loaf Cake Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to 350°F (175°C) and generously greasing and flouring a 9×5-inch loaf pan. This simple prep ensures your loaf comes out cleanly and forms that perfect crust we all love.
Step 2: Combine Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly mixed. Setting these aside ensures your leavening agents are evenly distributed for a perfectly risen cake.
Step 3: Mix Eggs and Sugar
Grab a large bowl and whisk the eggs and sugar together until the mixture is smooth and fully combined. This step creates a light base for your batter, helping that sugar dissolve and blend seamlessly with the eggs.
Step 4: Add Wet Ingredients
Into the egg and sugar mixture, stir in the sour cream or Greek yogurt, oil, lemon zest, fresh lemon juice, lemon extract, and vanilla extract. Mixing these together gives you the moist, flavorful heart of this Lemon Poppy Seed Loaf Cake Recipe.
Step 5: Incorporate Dry Ingredients
Gradually add the dry ingredients to the wet mixture, folding gently until just combined. Avoid overmixing here to keep your loaf tender and airy.
Step 6: Fold in Poppy Seeds
Sprinkle the poppy seeds into your batter and fold them evenly throughout. These tiny seeds add that signature crunch and nutty surprise with every bite.
Step 7: Fill the Pan
Pour the batter into your prepared loaf pan and spread it out to an even layer. This ensures your cake bakes uniformly and develops a lovely golden top.
Step 8: Bake the Loaf
Bake for 50 to 60 minutes or until a toothpick inserted into the center comes out clean. Once baked, let the loaf cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. Patience here rewards you with the best texture.
Step 9: Prepare the Lemon Glaze
While the loaf cools, whisk together powdered sugar, lemon juice, milk, and melted butter in a small bowl until smooth and glossy. This luscious glaze will add a sweet and tangy finish that perfectly complements the cake.
Step 10: Glaze and Enjoy
Once the loaf is completely cool, drizzle the lemon glaze generously over the top. Slice and savor every bright, flavorful bite of your homemade Lemon Poppy Seed Loaf Cake Recipe.

FAQs
Can I substitute Greek yogurt for sour cream in this Lemon Poppy Seed Loaf Cake Recipe?
Absolutely! Greek yogurt is a fantastic substitute for sour cream, offering a similar tang and moisture that keeps the loaf tender and flavorful.
What type of oil is best to use?
Vegetable or canola oil are best choices for this recipe because they have a neutral flavor and help maintain the moist texture without overpowering the lemon zest.
How can I tell when the loaf cake is done baking?
Testing with a toothpick is the most reliable method—insert it into the center of the cake and if it comes out clean or with just a few crumbs, your cake is perfectly baked.
Is the lemon glaze necessary?
The lemon glaze adds a wonderful burst of tangy sweetness that complements the loaf’s citrus flavor beautifully, but if you prefer a less sweet cake, you can skip it without a problem.
Can I make this Lemon Poppy Seed Loaf Cake Recipe vegan?
With some ingredient swaps like flax eggs and plant-based yogurt, you can adapt this recipe to be vegan, but texture and flavor might subtly differ from the classic version.
