Homemade Glazed Lemon Loaf Cake – Moist & Zesty Step-by-step instructions

Before you start

Preheat the oven to 350°F (175°C). Grease a 9x5-inch loaf pan and line it with parchment paper, leaving overhang on the long sides for easy removal.

Wash and chop the lemons, removing any seeds. Measure all ingredients before starting. The blender does most of the work, but having everything ready makes the process smooth.

Instructions

Blend and Mix

1. 1Blend the Wet Ingredients
   Preheat the oven to 350°F (175°C). Grease a 9x5-inch loaf pan and line it with parchment paper, leaving overhang on the long sides. Wash the lemons, chop them into wedges, and remove any seeds. Place the lemon wedges in a blender along with the granulated sugar, eggs, milk, and vegetable oil. Blend on high until the mixture is completely smooth and silky, about 30 seconds. The lemon puree should be fragrant and pale yellow.
   Look for The mixture is smooth with no visible lemon chunks and smells brightly citrusy.
   Tip Blend thoroughly so the lemon zest and pulp are fully incorporated into the batter.
2. 2Whisk the Dry Ingredients
   Pour the lemon puree into a large mixing bowl. Add the all-purpose flour, baking powder, and vanilla extract. Whisk everything together until just combined and no streaks of flour remain. Do not overmix; the batter should be thick but pourable. If the batter seems too thick, let it rest for a minute—the lemon puree will loosen it.
   Look for The batter is smooth, thick, and evenly yellow with a soft, airy texture.
   Tip Gently fold the flour in with a spatula to avoid overdeveloping the gluten.
3. 3Fill the Pan
   Pour the batter into the prepared loaf pan and smooth the top with a spatula. Tap the pan gently on the counter to release any air bubbles. The batter should come about three-quarters of the way up the sides of the pan.
   Look for The pan is filled evenly and the top is level.
   Tip Wipe any drips from the edges of the pan for a clean rise.

The lemon puree is silky and pale yellow, and the batter is thick, smooth, and evenly yellow with no lumps. It should smell intensely citrusy. The batter is ready to pour into the pan.

Bake and Cool

4. 4Bake the Loaf
   Place the pan in the preheated oven and bake for 40 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean or with only a few moist crumbs. The cake should be domed and spring back lightly when touched. If the top browns too quickly, tent loosely with foil during the last 10 minutes.
   Look for The loaf is golden, domed, and a toothpick comes out clean.

   Tip Rotate the pan halfway through baking for even browning.
5. 5Cool the Cake
   Remove the loaf from the oven and let it cool in the pan for 10 minutes. Then lift it out using the parchment overhang and transfer to a wire rack. Let it cool completely, about 1 hour, before glazing. If you glaze while warm, the glaze will melt and soak in instead of setting into a thick white drizzle.
   Look for The loaf is cool to the touch and firm enough to handle.
   Tip Cooling completely ensures the glaze sets properly on top.

The loaf is golden brown, domed, and a toothpick inserted in the center comes out clean. The kitchen smells like fresh lemon cake. The loaf has cooled completely on a wire rack, ready for glazing.

Glaze and Finish

6. 6Make the Glaze
   In a small bowl, whisk together the powdered sugar and fresh lemon juice until smooth and thick. The glaze should be pourable but not too thin—it should coat the back of a spoon. If it's too thick, add a few drops of lemon juice; if too thin, add a little more powdered sugar.
   Look for The glaze is smooth, white, and thick enough to cling.
   Tip Sift the powdered sugar first to avoid lumps.
7. 7Glaze the Loaf
   Pour the glaze generously over the cooled loaf, letting it drip down the sides. Use a spoon to spread it evenly if needed. Immediately sprinkle the freshly grated lemon zest over the wet glaze so it sticks. Let the glaze set for 5–10 minutes before slicing.
   Look for The loaf is covered in a white glaze with bright yellow zest speckles.
   Tip Place a sheet of parchment under the rack to catch drips.
8. 8Slice and Serve
   Use a serrated knife to slice the loaf into thick pieces. The interior should be moist, tender, and sun-yellow with a fine crumb. Serve at room temperature or slightly warm.
   Look for Slices show a moist, tender crumb and a crisp glaze top.
   Tip For clean slices, wipe the knife between cuts.

The glaze is thick, white, and pourable. It coats the loaf in a smooth layer, and the lemon zest sticks to the wet glaze. The finished loaf looks glossy and inviting, with a moist crumb visible when sliced.

Common mistakes

One common mistake is overmixing the batter after adding the flour, which can make the cake tough.

Mix just until no streaks remain. Another is not blending the lemons long enough—the puree should be completely smooth.

Also, don’t open the oven door during the first 30 minutes of baking, as the cake may sink. Finally, glaze the loaf only after it’s fully cooled; otherwise, the glaze will melt and soak in, losing its glossy finish.

How to tell it’s done

The loaf is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs. The top should be golden brown and spring back lightly when pressed.

The internal temperature of the cake should reach 160°F (71°C) on an instant-read thermometer. Let it cool completely before glazing to ensure the glaze sets properly.
