Glazed Lemon Loaf with Sour Cream
Not rated yet. Be the first.
Work the zest into the sugar with your fingers and the kitchen smells like lemons before the oven is even on. Glaze the loaf only when it has cooled, even with the whole family hovering.
The short version
Rub lemon zest into sugar, whisk in sour cream, oil, lemon juice and eggs, fold in the flour, and bake at 350°F for 45 to 55 minutes. Cool completely, then drizzle with lemon glaze.
What makes ours better
what we fixed so you don’t have to
-
Rub the zest into the sugar. It releases the lemon oils that live in the zest, so the loaf tastes of lemon, not just sour.
-
Use sour cream and oil. Sour cream adds moisture and a gentle tang, and oil keeps the crumb soft for days, even straight from the fridge.
-
Glaze only when the loaf is cool. A warm loaf melts the glaze and it runs off. A cool loaf lets it set into a thin, tart crust.

Steps
nobody opens the oven door. looking at you, Dad.
-
Heat the oven, line the pan
Set a rack in the center and heat the oven to 350°F. Grease a 9×5-inch loaf pan and line it with a strip of parchment that hangs over the long sides.
-
Rub zest into sugar
In a large bowl, rub the sugar and lemon zest together with your fingertips for about a minute, until the sugar is damp, yellow-tinged and smells strongly of lemon.
Zest the lemons before you juice them. A juiced lemon is almost impossible to zest.
-
Whisk the wet ingredients
Add the sour cream, oil, eggs, 3 tablespoons of lemon juice and the vanilla to the sugar and whisk until smooth.
-
Fold in the flour
Sprinkle the flour, baking powder and salt over the batter and fold with a rubber spatula just until no streaks of flour remain. The batter will be thick and smooth.
Stop as soon as the flour is gone. Overmixing makes a dense loaf with a peaked, cracked top.
-
Pan it
Scrape the batter into the pan and smooth the top.
-
Bake
Bake until the loaf is golden and a skewer in the center comes out with a few moist crumbs, 45 to 55 minutes. If the top is browning too much at 35 minutes, tent loosely with foil.
About 45 min. Cook mode has a timer for this step.
-
Cool completely
Let the loaf rest in the pan for 20 minutes, then lift it out by the parchment onto a rack. Cool completely, about 1 hour.
About 20 min. Cook mode has a timer for this step.

Glaze
Whisk the powdered sugar with 2 tablespoons of lemon juice until smooth and thick enough to ribbon off the whisk. Add a few drops more juice if it's stiff, or a spoonful of sugar if it's runny. Drizzle over the loaf and let it set for 15 minutes.
Good to know
the stuff I’d tell you over the phone
- Bottled lemon juice works in the glaze in a pinch, but fresh juice tastes brighter in the loaf.
- Add 1 tablespoon of poppy seeds to the dry ingredients for a lemon poppy seed loaf.
- For a richer, more pound-cake-like version, swap the oil for the same weight of melted butter, browned and cooled.
- For 12 muffins, bake 20 to 24 minutes.
- Storage. Wrapped, at room temperature 3 days, or in the fridge up to 5 days. Unglazed and frozen, 3 months; glaze after thawing.
Questions, answered
the questions my cousins text me
Why did my lemon loaf sink in the middle?
The loaf probably came out early, or the oven was too cool. Bake until a skewer comes out with moist crumbs only, and avoid opening the oven door in the first 30 minutes.
Can I use Greek yogurt instead of sour cream?
Yes. Use full-fat plain Greek yogurt in the same amount. The loaf will be a touch more tangy.
How do I get more lemon flavor?
Use plenty of zest, which is where most of the flavor lives, and rub it into the sugar. You can also brush the warm loaf with 2 tablespoons of lemon juice stirred with 1 tablespoon of sugar.
Why does my glaze disappear?
The loaf was still warm, or the glaze was too thin. Cool the loaf fully and make the glaze thick, like honey.
Can I use Meyer lemons?
Yes, the loaf will be a little floral and less tart. Use them one for one, and cut the glaze juice to taste.
