1-First Step: Preparation and Mise en Place Start by preheating your oven to 350°F (180°C). It is crucial that the oven is fully hot before the batter goes in, so give it plenty of time to warm up. While the oven heats, grab a 9×5-inch loaf pan and grease it thoroughly. You can use butter, oil, or a non-stick baking spray. For extra insurance, you can line the bottom with parchment paper to make lifting the loaf out later a breeze. Next, sift your dry ingredients. In a medium bowl, sift together the 1 ¾ cups of all-purpose flour, 1 teaspoon of baking powder, and ½ teaspoon of salt. Sifting breaks up any clumps and incorporates air into the flour. Set this bowl aside so it is ready to go when you need it. Ensuring your eggs, milk, and lemon juice are at room temperature will help them mix more evenly with the butter, so take them out of the fridge about 30 minutes before you start.

2-Second Step: Creaming the Butter and Sugar In a large mixing bowl, combine the ¾ cup of softened butter and ¾ cup of sugar. Using a hand mixer or a stand mixer fitted with a paddle attachment, beat these together on medium speed. You want to cream them until the mixture is pale and fluffy. This process usually takes about 3 to 5 minutes. Do not rush this step! The air bubbles you are creating here are what will make the loaf light and tender. If you notice the mixture looking chunky or curdled at any point, turn off the mixer. Use a rubber spatula to press the butter down against the side of the bowl and smear it. This helps warm it up slightly and smooth out the texture. Once it looks creamy again, continue mixing. Using softened butter rather than melted butter is key here because softened butter holds air pockets, whereas melted butter cannot.

3-Third Step: Adding Wet Ingredients and Flavor With the mixer on low speed, add the 3 large eggs one at a time. Wait until the first egg is fully incorporated before adding the next. This prevents the batter from separating. Once the eggs are blended in, add the 2 tablespoons of fresh lemon juice, the zest of 2 lemons, and the 2 tablespoons of poppy seeds. Mix these just until they are evenly distributed throughout the batter. The lemon zest is packed with flavor oils, so make sure you are grating just the yellow part and avoiding the white pith underneath, which can be bitter. The poppy seeds should be fresh for the best crunch. Mixing on low speed during this stage is important to prevent generating too much heat, which can melt the butter and ruin the texture you worked so hard to create.

4-Fourth Step: Combining Wet and Dry Mixtures Now it is time to incorporate the dry ingredients and the milk. With the mixer still on low speed, add about half of the flour mixture to the bowl. Let it mix until just barely combined. Then, pour in half of the ¾ cup of milk. Repeat this process, adding the remaining flour followed by the remaining milk. The key here is to mix only until combined. As soon as you do not see streaks of dry flour, stop the mixer. Overmixing develops gluten, which can make the bread tough and chewy rather than soft and cake-like. It is okay if the batter looks a little thick or lumpy; that is normal. Scrape down the sides of the bowl with a spatula one last time to make sure no pockets of flour are hiding at the bottom.

5-Final Step: Baking and Glazing Pour the batter into your prepared 9×5-inch loaf pan. Use your spatula to spread the top evenly. Place the pan in the center of your preheated oven. Bake for 50 to 55 minutes. Every oven is different, so start checking for doneness around the 50-minute mark. Insert a wooden toothpick into the center of the loaf. If it comes out clean or with just a few moist crumbs, it is done. Let the loaf cool in the pan for about 10 minutes. This allows it to firm up slightly so it does not break when you remove it. After 10 minutes, carefully turn it out onto a wire cooling rack to cool completely. If you want to add the glaze, wait until the loaf is cool to the touch. Whisk together 1 tablespoon of lemon juice and 1 cup of sifted powdered sugar. Add the 3 teaspoons of milk gradually until you reach a thick but pourable consistency. Spoon this over the top of the loaf and let it harden before slicing.
