Preheat your oven to 350°F (175°C) and grease a 9-inch loaf pan.
In a large bowl, add the eggs, sugar, and sour cream. Beat with a hand mixer or a stand mixer until smooth.
Gradually add the oil while continuing to mix until well combined.
Add the lemon juice, lemon zest, and vanilla extract, and beat for a few minutes until fully incorporated.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, beating just until combined. Be careful not to overmix.
Pour the batter into the greased loaf pan and bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely before glazing.
