This perfectly lemony lemon loaf cake is rich and moist, with a dense but fluffy crumb, topped with sweet and tart lemon icing. I based this lemon pound cake recipe off of my high altitude pound cake, but with plenty of fresh lemon juice and zest for loads of lemon flavor. The cake itself isn’t too sweet, so the lemon icing is the perfect finish for this simple but delicious cake.

Why You’ll Love This Cake
Quick and Easy to Make. Making the cake batter is a quick process of creaming butter and sugar, then adding the wet and dry ingredients.
Perfect Pound Cake Texture. I love the dense cake crumb that’s so rich, moist, buttery and full of lemon flavor.
Stays Fresh for Days. One of the best things about pound cake is how soft and moist they stay for days after baking. Three days after baking this cake, it was still as fresh tasting as when it came out of the oven.
High Altitude Tested. I develop all the recipes on my site for Denver’s altitude of 5,280 feet. If you’re at a lower or higher elevation, please see my FAQs for guidance on adjusting recipes for your altitude.

Ingredients
Cake
- Unsalted Butter. Makes the cake moist, rich and flavorful.
- Granulated Sugar. Adds sweetness and moisture.
- Eggs. Gives the cake structure and richness.
- Flour. All-purpose flour adds structure and strength.
- Baking Powder. Leavening agent.
- Salt. Balances the sweetness.
- Lemons. Fresh lemon zest and juice adds flavor and acidity for a tender cake crumb.
- Sour Cream. Adds moisture and acidity for a soft, tender cake crumb.
- Vanilla + Lemon Extracts. Flavor.
TIP: Make sure all ingredients are at room temperature for best results.
Icing
- Powdered Sugar. Sweetens and thickens the icing.
- Light Corn Syrup. Stabilizes the sugar and sets the icing.
- Lemon Juice. Thins the icing to a pourable consistency and adds tartness to balance the sweetness.
Instructions
Cake
- Preheat the oven to 325F, and line a standard-sized loaf pan with a piece of parchment paper so that the paper hangs over two sides. This makes it easy to lift the cake out of the pan.
- In the bowl of your stand mixer fitted with the paddle attachment, beat the butter and sugar for 5 minutes on medium speed, scraping the bowl down several times.
- Beat in the eggs, one at a time, beating each for 10 seconds before adding the next.
- In a separate bowl, sift together the flour, baking powder and salt.
- Zest the lemons, then juice the lemons into a liquid measuring cup; you’ll need 1/4 cup of juice. Combine the lemon juice, zest, sour cream, vanilla and lemon extracts.
- With the mixer on low, add the flour mixture in 3 additions, alternating with the lemon juice mixture, starting and ending with the flour. Mix just until mostly combined, then use a spatula to fold in any remaining bits of flour. The batter will be thick.
- Spread the batter into the loaf pan. Bake on the center oven rack for about 55-60 minutes, until a cake tester inserted in the center of the cake comes out clean.
- Cool the cake in the pan for 20 minutes, then lift the cake out by grabbing onto the overhang of parchment paper. Set on a cooling rack to cool to room temperature before pouring on the icing and serving.
TIP: This recipe makes a generous amount of icing to cover the top of the cake and drip down the sides. If you like a little less, just cut the icing recipe in half.
Icing
- Whisk together all ingredients until the icing is a smooth, thick drizzling consistency.
- Pour the icing over the cake, letting it drip down the sides. The icing will set in about 15-20 minutes. Zest some fresh lemon zest on top of the icing.

Frequently Asked Questions
Can this recipe be doubled?
Yes, you can double the recipe to make two loaves.
Will this recipe work as a bundt cake?
Absolutely. Just double the recipe to make a large, standard-sized bundt cake (12-cup capacity).
Can I make this into a layer cake?
I’m not sure. It might be a bit dense for a layer cake. I recommend this lemon cake recipe for a layer cake.
What can I substitute for the sour cream?
Instead of the sour cream, you can use full-fat buttermilk or plain, unsweetened Greek yogurt.
Should I use fresh or bottled lemon juice?
Either works, but I recommend fresh lemon juice, since you need fresh lemons for their zest anyway. The zest adds more lemon flavor to the cake than just the juice on its own.
Is this a dense cake?
This is a pound cake, which has a dense cake crumb that’s very soft, tender and moist.
How should I store leftover cake?
Keep the cake in an airtight container at room temperature for 3-5 days.
Can I add blueberries to the cake batter?
I haven’t tried it, but I don’t see why it wouldn’t work. The batter is thick, so just briefly fold in fresh blueberries after mixing up the batter. Since blueberries make baked goods sooooo moist, I would keep the leftover cake refrigerated so it doesn’t spoil from the moisture.

This was my first time making any kind of loaf and it turned out perfectly! I had to cook it for a few minutes longer but was very successful!
This baked up perfectly at 8600 ft. Delicious!
This recipe is a WINNER guys!! I doubled this recipe to make a Bundt cake for a work event and it was an absolute hit! It was so moist, the perfect amount of lemon flavor, and multiple people asked for the recipe after.
A few tips if you’re going the Bundt cake route: Grease and flour the pan and you’ll have no issues with sticking. Ice in two phases, in order to get it to stick, rather than just soaking into the cake. Ice on a cooling rack over a sheet pan, in order to prevent pooling of icing in the middle of the Bundt cake. And you may need to cook a little longer than 60 min—trust your cake tester/skewer! (For context, I’m also in Denver.)
i never bake, maybe once every two years so i am by no means an expert but i measured everything in grams (i’ve read it’s better for baking). also, i made a few tweaks to the recipe because I live 2 inches shy of 7000′ elevation. the changes i made were using 3 eggs, olive oil (118g) instead of butter and 1 pint fresh blueberries (approximately 150g folded in at the end, then sprinkled the remaining on top). I also liberally sprinkled turbinado sugar on the top (i saw it in another lemon load recipe) oh, i did not use lemon extract. as for baking due to elevation i increased the heat to 350 degrees for exactly 60 minutes turning the pan at the half way mark. i then decreased the heat to 335 for 10 minutes. turned the oven off, opened the door and let it sit. OH MY WAS IT DELICIOUS! i promptyl baked another one for a party tomorrow night. (Curly girl, i’m a curly girl, too!)
