This moist lemon loaf cake is an easy, classic lemon cake made in a loaf pan with fresh lemon zest and a homemade lemon syrup. Soft, tender, and full of bright citrus flavor, it’s the perfect simple lemon drizzle cake for everyday baking.
Preheat your oven to 325°F (160°C fan). Grease and lightly flour a loaf pan.
Wash the lemons in hot water. Finely zest them, then rub the zest into the sugar using your fingers until the sugar feels slightly damp and smells intensely lemony.
Add the eggs to the lemon sugar and beat for 2–3 minutes until pale and slightly fluffy.
In a separate bowl, whisk together flour, cornstarch, baking powder, and salt.
Stir the sour cream and melted butter together.
Add the dry ingredients and the butter mixture alternately to the egg mixture, mixing just until combined. Do not overmix.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 45–55 minutes, or until a toothpick inserted in the center comes out clean.
Make the Lemon Syrup
While the cake is baking:
Add water, lemon juice, and sugar to a small saucepan.
Heat gently, stirring until the sugar is fully dissolved.
Let it simmer for 1–2 minutes, then keep warm.
Soak the Cake
As soon as the cake comes out of the oven:
Poke holes all over the top with a skewer or toothpick.
Slowly spoon the warm syrup over the hot cake, a little at a time, letting it soak in before adding more.
This step is what makes the cake incredibly moist and gives it that bakery-style texture.
Let the cake cool completely in the pan, then remove and dust with powdered sugar or cover with a simple icing made from lemon juice and icing sugar.
