Lemon Sour Cream Pound Cake That Stays Soft for Days
This lemon sour cream pound cake is the one I reach for when I want a buttery, tangy loaf that never turns dry a day later. It’s simple enough to mix up on a Tuesday afternoon but looks lovely sliced and fanned out with a bowl of berries.
The crumb is tight and tender, and the crackly lemon glaze sets up in minutes so you can slice it the moment it cools.
Why This Cake Stays Soft for Days
The first bite is all butter and fresh lemon, with a fine, velvety crumb that still feels moist on day three. The sour cream does the heavy lifting here. It slows down gluten development and adds enough fat to keep every slice tender.
The glaze is nothing more than lemon juice and powdered sugar, but it turns into a sweet, tart crust that breaks with a quiet snap. It’s the kind of cake you can pack in a lunchbox, then dress up with whipped cream when friends come over.
Ingredients
- 1 1/2 cups (190g) all-purpose flour: spooned and leveled, not scooped
- 1/2 tsp baking powder: helps lift the dense crumb
- 1/2 tsp baking soda: reacts with the sour cream for extra tenderness
- 1/2 tsp salt
- 1/2 cup (115g) unsalted butter, softened: bring to room temperature before creaming
- 1 cup (200g) granulated sugar
- 2 large eggs, at room temperature
- 1 tbsp lemon zest: from about 2 large lemons
- 2 tbsp fresh lemon juice
- 1 tsp vanilla extract
- 1/2 cup (120g) full-fat sour cream
Glaze
- 1 cup (120g) powdered sugar
- 2 to 3 tbsp fresh lemon juice: add slowly until the glaze is thick but pourable
Variations / Substitutions
- Swap the lemon for orange: use orange zest and juice in the cake and glaze for a milder, sweeter loaf.
- Use buttermilk instead of sour cream: the crumb will be a little lighter and tangier, but still very moist. Reduce buttermilk to 1/3 cup plus 2 tbsp.
- Add poppy seeds: fold 2 tsp into the dry ingredients for a lemon poppy seed version.
- Make it gluten-free: use a quality 1:1 gluten-free flour blend that includes xanthan gum.

How to Make Lemon Sour Cream Pound Cake
Step 1: Cream the Butter and Sugar
Preheat the oven to 350°F (175°C) and grease a 9×5-inch loaf pan, then line it with parchment paper so the ends hang over the sides. Place the 1/2 cup softened butter and 1 cup sugar in a large bowl and beat on medium-high speed until the mixture is pale and fluffy, about 3 minutes. You will see the color change from yellow to nearly white, and it will look almost like whipped frosting.
Stop and scrape the bowl a couple of times. If the butter was truly soft, the sugar will dissolve into it easily and the whole thing will feel light when you drag a spatula through.
Step 2: Add the Eggs and Lemon
With the mixer on medium, beat in the 2 eggs one at a time, letting each disappear fully before adding the next. When the second egg is in, mix in the 1 tbsp lemon zest, 2 tbsp lemon juice, and 1 tsp vanilla extract. The batter may look a little curdled at this point, and that is completely normal.
The lemon juice adds acid that will react with the baking soda later, so do not skip it. The scent at this stage is pure lemon, sharp and fresh.
Step 3: Alternate the Dry Mix and Sour Cream
Whisk together the 1 1/2 cups flour, 1/2 tsp baking powder, 1/2 tsp baking soda, and 1/2 tsp salt in a separate bowl. Add the dry mix to the butter mixture in three additions, alternating with the 1/2 cup sour cream, starting and ending with the dry. Stir each addition just until the flour disappears. Overworking the batter now will make the cake tough.
The batter will be thick and creamy, and you should still see tiny flecks of lemon zest throughout. Use a rubber spatula for the last stir to catch anything hiding at the bottom of the bowl.
Step 4: Bake the Cake
Scrape the batter into the prepared pan and smooth the top. Bake for 55 to 65 minutes, rotating the pan halfway through, until the top is deeply golden and a toothpick inserted in the center comes out clean or with just a few moist crumbs. The cake will pull away slightly from the sides when it’s ready.
Let it cool in the pan for 10 minutes, then use the parchment to lift it out and transfer to a wire rack. Cool the loaf completely before glazing, or the glaze will melt right off.
Step 5: Glaze and Slice
Whisk the 1 cup powdered sugar with 2 tbsp lemon juice until smooth. Add the last tablespoon of juice a little at a time until the glaze falls in a thick ribbon that slowly disappears back into itself. Spoon it over the cooled cake and let it set for 15 minutes.
Slice with a serrated knife and serve. The glaze will crackle softly under the blade, and each slice will have a buttery, lemony crumb that holds together perfectly.
Tips for the Best Pound Cake
- Bring the butter, eggs, and sour cream to room temperature before you start. Cold ingredients will not cream well and can make the batter curdle.
- Use the zest of the lemons, not just the juice. The oils in the peel carry most of the lemon scent and flavor.
- Do not open the oven door during the first 45 minutes. A rush of cool air can make the cake sink in the center.
- If the top browns too quickly before the center is set, tent a piece of foil loosely over it after 40 minutes.
- For the smoothest glaze, sift the powdered sugar to remove any lumps.
Bake times by pan; the cake is done when a toothpick comes out clean and the center reads 200°F to 205°F (93°C to 96°C).
| Pan Type | Bake Time | Adjustments |
|---|---|---|
| 9×5-inch metal loaf pan | 55–65 mins | Check at 55 minutes |
| 8.5×4.5-inch glass pan | 60–70 mins | Reduce oven temp by 25°F |
| 10-cup bundt pan | 50–60 mins | Start checking 5 minutes early |
Keeping the Cake Fresh
- Room temperature: wrap the cooled, unglazed cake tightly in plastic and keep at room temperature for up to 3 days. Glaze just before serving for the shiniest look.
- Refrigerate: wrapped tightly, it will stay moist up to 5 days. Bring slices to room temperature before eating for the softest crumb.
- Freeze: wrap the unglazed loaf in plastic then foil, and freeze up to 3 months. Thaw overnight on the counter and glaze before slicing.
Frequently Asked Questions
Can I use bottled lemon juice?
Yes, but fresh lemon juice gives a brighter, less metallic taste. If you only have bottled, reduce the amount slightly so the glaze doesn’t get too sharp.
Is the crack down the middle normal?
Yes, a long crack is classic for pound cake. It means the top set before the inside finished rising, which is exactly what you want.
Can I double the recipe?
You can. Pour the batter into a greased 10-cup bundt pan and bake for 60 to 75 minutes, checking at the one-hour mark.
Why did my glaze turn thin and translucent?
Too much lemon juice was added. Stir in more sifted powdered sugar, a tablespoon at a time, until it thickens up and turns opaque white again.
