Method
- Preheat oven to 350°F (175°C). Line a 9x5-inch loaf pan with parchment paper, leaving an overhang.
- In a large bowl, rub the fresh lemon zest into the granulated sugar with your fingers until fragrant and pale yellow.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
- Add softened butter and oil to the lemon sugar. Beat with a mixer on medium-high until light and fluffy (3-4 minutes).
- Add eggs one at a time, mixing well after each. Mix in the vanilla extract and lemon juice.
- On low speed, add 1/3 of the flour mixture, then 1/2 of the sour cream. Repeat, ending with the final 1/3 of flour. Mix just until combined. Do not overmix.
- Pour batter into the prepared pan and smooth the top. Bake for 50-60 minutes, tenting with foil at 40 minutes if browning too quickly. A toothpick should come out clean.
- Cool in the pan for 15 minutes, then use the parchment sling to remove the cake to a wire rack to cool completely.
- For the glaze, whisk powdered sugar, lemon juice, and cream until thick and smooth. Adjust consistency with more juice or sugar if needed.
- Pour the glaze over the completely cooled cake, allowing it to drip down the sides. Garnish with fresh lemon slices. Let the glaze set before slicing.
Notes
Ensure all cold ingredients (eggs, butter, sour cream) are completely at room temperature before beginning to ensure a smooth, uncurdled batter.
