Combine sour cream, granulated sugar, eggs, lemon zest, lemon extract, vanilla extract, and oil in a bowl.

In another bowl, whisk together flour, baking powder, baking soda, and salt.

Gradually add the dry mixture to the wet ingredients and mix until well combined.

Pour the batter into a greased 9×5 inch loaf pan.

Bake in a preheated oven at 350°F until the top is golden brown and a toothpick inserted into the center comes out clean, about 60 minutes.

For the lemon syrup, heat lemon juice and sugar in a small saucepan until the sugar dissolves completely.

Once the loaf is done baking, poke holes on top using a fork or toothpick.

Slowly pour the lemon syrup over the loaf, letting it soak in.

Remove the loaf from the pan and drizzle the lemon icing over it. Let it cool before slicing.

For the lemon icing, mix confectioners sugar, lemon juice, and lemon zest until smooth.
