Cook Time 1 hour
Total Time 1 hour 15 minutes
Serving Size 8 to 10 slices (1 loaf)

Equipment

  • 9x5-inch loaf pan
  • Mixing bowls
  • Whisk
  • Spatula
  • Wire rack
  • Parchment paper

Ingredients

For the Cake:

  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup granulated sugar
  • 2 tablespoons lemon zest from about 2 lemons
  • 4 large eggs
  • 1 cup sour cream 8 ounces
  • ½ cup fresh lemon juice
  • cup whole milk
  • cup vegetable oil
  • 1 teaspoon vanilla extract

For the Glaze:

  • 2 ¾ cups powdered sugar
  • 4 tablespoons fresh lemon juice or to taste

Instructions

  • Preheat the oven to 350℉. Grease a 9x5-inch loaf pan and line it with parchment paper, leaving an overhang on the sides for easy removal.
  • In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. In a large mixing bowl, combine the sugar and lemon zest, rubbing the zest into the sugar with your fingers until fragrant.
  • Add the eggs one at a time, beating well after each addition until light and fluffy. Stir in the sour cream, lemon juice, milk, vegetable oil, and vanilla extract until fully combined.
  • Gradually add the dry ingredients to the wet mixture, stirring until just combined. Pour the batter into the prepared loaf pan and smooth the top.
  • Bake for 55-60 minutes, or until a toothpick inserted in the center comes out clean. Cool in the pan for 20 minutes, then lift out and transfer to a wire rack to cool completely.
  • To make the glaze, whisk together powdered sugar and lemon juice in a medium bowl until smooth, adjusting the consistency with more lemon juice if needed.
  • Once the cake is completely cool, drizzle the glaze over the top and let it drip down the sides. Allow the glaze to set for 30 minutes before slicing.

Notes

  • For extra brightness, brush the warm loaf with a few tablespoons of lemon syrup before glazing.
  • The cake flavor deepens after resting for a few hours, so it’s even better the next day.
  • You can swap sour cream with full-fat Greek yogurt for a similar texture.
  • Make sure the cake is completely cool before glazing to prevent the glaze from melting.
  • Store the loaf in an airtight container at room temperature for up to 2 days, or refrigerate for up to 1 week. It also freezes beautifully for up to 3 months. Just wrap tightly in plastic wrap and foil before freezing.
