Instructions

  • Preheat oven to 350°F and line a 9x5-inch loaf pan with parchment paper, leaving overheang on the sides so that you can remove the bread once baked (see video).
  • In the bowl of a stand mixer fitted with the paddle attachment, stir the flour, 1 cup sugar, baking powder, baking soda, and salt together on low until just combined.
    2¼ cups all-purpose flour, 1¼ cup granulated sugar, 1 tsp baking powder, ½ tsp baking soda, ½ tsp kosher salt

    ⅔ cup sour cream, 2 tbsp lemon extract, 1 tbsp lemon zest
  • Pour the batter into the prepared loaf pan.
  • Bake for 60 minutes, or until a toothpick inserted into the middle comes out clean.
  • Allow the bread to cool for 15 minutes in the pan.
  • While the bread is cooling, heat the remaining ¼ cup sugar and ¼ cup lemon juice in a small saucepan, stirring until the sugar is fully dissolved.
    ¼ cup lemon juice
  • Once bread has cooled 15 minutes, remove from the loaf pan and transfer to a parchment lined cooling rack.
  • Spoon the lemon/sugar syrup over the bread, allowing it to soak in.
  • Allow the bread to cool completely.
  • Stir together the powdered sugar, sour cream, and lemon juice until smooth. Add more lemon juice if you need to make the mixture thinner.
