Golden Whole Lemon Loaf Cake Step-by-step instructions

Before you start

Before starting, preheat the oven to 350°F (175°C) and position a rack in the center. Line a 9x5-inch loaf pan with parchment paper, leaving overhang on the two long sides for easy lifting.

Wash the lemon thoroughly, as the peel will be blended into the batter. Have all ingredients measured and ready. The blender will be used for the wet mixture, so ensure it is clean and dry. Prepare a wire cooling rack for after baking.

Instructions

Phase 1: Blend and Mix

1. 1Blend the Citrus Base
   Preheat the oven to 350°F (175°C). Line a 9x5-inch loaf pan with parchment paper, leaving some overhang on the long sides for easy removal. Wash the lemon thoroughly. Cut the lemon into wedges, removing any seeds. Place the lemon wedges into a blender pitcher. Add the eggs, granulated sugar, milk, and vegetable oil. Blend on high until the mixture is completely smooth and bright yellow, with no visible pieces of peel. This takes about 30 seconds to 1 minute, depending on your blender.
   Look for The blended mixture should be a uniform, bright yellow liquid with a fragrant lemon aroma. No large pieces of lemon peel should remain.
   Tip Make sure the lemon is well washed to remove any wax or residue. Organic lemons are ideal because the peel is used.
2. 2Incorporate Dry Ingredients
   Pour the blended lemon mixture into a large mixing bowl. Sift the all-purpose flour, baking powder, and vanilla sugar over the wet ingredients. Whisk gently until just combined, being careful not to overmix. The batter should be smooth, thick, and velvety. Overmixing can develop the gluten and make the cake tough, so stop as soon as there are no dry streaks of flour visible.
   Look for The batter should be smooth and pourable, with a thick, velvety consistency. No lumps of flour remain.
   Tip Sifting the flour not only removes lumps but also aerates it, helping to create a lighter crumb.

After whisking in the dry ingredients, the batter should be thick, smooth, and velvety, with no lumps. It should pour easily from the bowl into the loaf pan.

Phase 2: Bake to Golden

3. 3Bake the Loaf
   Pour the batter into the prepared loaf pan and smooth the top with a spatula. Bake in the preheated oven for 42 minutes, or until the cake is golden brown and a toothpick inserted into the center comes out clean. The top should be tall, cracked down the center, and spring back when lightly pressed. The internal temperature of the cake should reach at least 200°F (93°C) in the center to ensure it is fully baked.
   Look for The cake is tall, deeply golden, and has a natural crack down the center. A toothpick inserted in the middle comes out with a few moist crumbs, not wet batter.

   Tip If the top is browning too quickly, tent loosely with foil after 30 minutes. Start checking for doneness at 38 minutes.

Phase 3: Glaze and Finish

4. 4Make the Lemon Glaze
   While the cake is baking, prepare the glaze. In a small bowl, whisk together the confectioners' sugar and freshly squeezed lemon juice until smooth and thick. The glaze should be thick but pourable; if it is too thick, add a few more drops of lemon juice; if too thin, add a little more powdered sugar.
   Look for The glaze is glossy, white, and thick enough to coat the back of a spoon.
   Tip For a smoother glaze, sift the confectioners' sugar before whisking. Fresh lemon juice gives the best flavor.
5. 5Glaze and Serve
   Once the cake is baked, remove it from the oven and let it cool in the pan for 10 minutes. Then transfer to a wire rack. While the cake is still warm, pipe or drizzle the glaze over the top in a zigzag pattern. Let the glaze set for a few minutes before slicing. Slice thickly and serve warm or at room temperature.
   Look for The glaze drizzles over the golden crust, creating white streaks. The cake is moist and fragrant when sliced.
   Tip Glazing while warm allows the glaze to slightly melt into the crust, creating a lovely sheen.

The glaze should be thick, glossy, and white, drizzling over the warm cake in a beautiful zigzag. As it sets, it may slightly melt into the crust, creating a shiny finish. The cake is moist and fragrant when sliced.

Common mistakes

Avoid overmixing the batter once the flour is added; this can develop gluten and result in a tough, dense cake. Mix just until no dry streaks remain. Ensure the lemon is thoroughly blended; any large pieces of peel can create bitter pockets.

When making the glaze, start with less lemon juice and add more as needed—a too-thin glaze will run off the cake. Finally, let the cake cool completely before slicing to get clean cuts, though it is delicious warm.

How to tell it’s done

The cake is done when the top is golden brown, and a toothpick inserted into the center comes out clean or with a few moist crumbs attached. The internal temperature should read at least 200°F (93°C) in the center.

The top will have a natural crack, which is characteristic of this loaf. If the top is browning too quickly, tent loosely with foil after 30 minutes. Let the cake cool in the pan for 10 minutes before transferring to a rack.
