Preheat the oven to 350°F (175°C). Grease and flour a bundt or loaf pan.
In a large bowl, cream together butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in lemon juice and lemon zest.
In a separate bowl, combine flour, baking soda, and salt.
Add the dry ingredients to the wet mixture alternately with sour cream, beginning and ending with the dry ingredients.
Pour the batter into the prepared pan and smooth the top.
Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Let the cake cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
For the glaze: Mix powdered sugar with lemon juice until smooth and pourable.
Drizzle the glaze over the cooled cake before serving.
