Ingredients
Scale
- 1 ⅔ cups (335 g) granulated sugar
- 3 tablespoons lemon zest
- ½ cup (113 g) unsalted butter, softened
- ¼ cup (60 ml) neutral cooking oil
- ⅔ cups (160 g) sour cream
- 4 large eggs, room temperature, yolks and whites divided
- 1 tablespoon lemon juice
- 1 teaspoon vanilla extract
- 2 ¼ cups (250 g) cake flour
- ¾ teaspoon baking powder
- ¾ teaspoon table salt
- 1 ½ cups (190 g) powdered sugar
- 1-3 tablespoon lemon juice, as needed
- 1 ½ tablespoons salted butter, melted
- ¼ teaspoon vanilla extract
Instructions
- Preheat the oven to 350F (175C) and lightly grease and flour a 9×5” bread pan or line with parchment paper.
- In a large bowl, combine sugar, butter, and lemon zest. Beat with an electric mixer until fluffy, about 3-4 minutes.
- Mix in the oil until well combined.
- In another bowl, whisk together sour cream, egg yolks, lemon juice, and vanilla extract. Stir this mixture into the butter mixture on low speed until fully blended.
- In a separate bowl, whisk together cake flour, baking powder, and salt. Gently fold the dry ingredients into the wet mixture until fully combined.
- In a clean, dry bowl, whip the egg whites using an electric mixer until stiff peaks form.
- Gently fold the whipped egg whites into the batter until just combined. Pour the batter into the prepared loaf pan.
- Bake in the preheated oven for 74 minutes, or until a skewer inserted in the center comes out clean or with a few moist crumbs.
- Let the loaf cool in the pan for 15 minutes before loosening the edges with a knife and transferring it to a cooling rack. Prepare the lemon glaze.
- For the lemon glaze, whisk together powdered sugar, 1 tablespoon lemon juice, melted butter, and vanilla extract. Add more lemon juice as needed until smooth and pour over the warm loaf.
- Let the loaf cool and glaze set for at least 30 minutes before slicing.
Notes
For a lighter texture, ensure the egg whites are whipped to stiff peaks before folding them into the batter.
Feel free to adjust the lemon juice in the glaze based on your preferred sweetness and tartness.
Store any leftovers in an airtight container to retain freshness.
