Moist Lemon Buttermilk Pound Cake
This lemon buttermilk pound cake has a tender, tight crumb and a bright citrus tang that keeps every bite interesting. It is the kind of sturdy, buttery cake that feels right at any time of day, whether you slice it for breakfast, pack it in a lunchbox, or dress it up with berries after dinner.
The lemon glaze soaks into the warm top just enough to give you a sticky, crackly finish without making the cake soggy. It is even better the next day, if you can wait that long.
Why This Lemon Pound Cake Stays in My Rotation
The buttermilk does a lot of quiet work here. Its acidity softens the flour proteins, so the cake bakes up dense but not dry. Every slice stays moist for days, which makes this the cake I reach for when I need something reliable.
Fresh lemon zest and juice give you that sharp, clean flavor that a bottle never can. The glaze on top adds a second jolt of lemon right as you bite in, balancing the rich butter and eggs beneath.
Ingredients
- 1 cup unsalted butter, softened: let it sit at room temperature until it gives easily when pressed
- 2 cups granulated sugar
- 4 large eggs, at room temperature
- 3 cups all-purpose flour, spooned and leveled: do not pack the flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 1 cup full-fat buttermilk, at room temperature
- 2 tablespoons lemon zest: from about 2 large lemons
- 1/4 cup fresh lemon juice: same lemons, after zesting
- 1 teaspoon vanilla extract
For the Glaze
- 1 cup powdered sugar, sifted if lumpy
- 2 to 3 tablespoons fresh lemon juice: adjust for a pourable consistency
Variations / Substitutions
- No buttermilk: stir 1 tablespoon lemon juice or white vinegar into 1 cup whole milk and let it sit 5 minutes. The cake will be slightly less tender but still good.
- Orange version: swap lemon zest and juice for orange zest and juice. The cake becomes sweeter and mellower.
- Poppy seed variation: fold 1 tablespoon poppy seeds into the batter after the flour. Adds a nice little crunch.
- Dairy-free: use a stick-style vegan butter and a dairy-free buttermilk substitute (oat milk plus lemon juice). The texture shifts a touch but works.

How to Make Moist Lemon Buttermilk Pound Cake
Step 1: Cream the Butter and Sugar
With a stand mixer or hand mixer, beat the 1 cup softened butter and 2 cups sugar together on medium speed for about 3 minutes. Stop once the mixture looks pale, fluffy, and almost whipped. Scrape the bowl at least once so no butter hides at the bottom.
The butter needs to be truly soft, not just slightly warm. If you press a finger into it and leave an indent, it is ready. Cold butter will not trap air well, and the cake will turn out heavy.
Step 2: Add the Eggs and Lemon
Crack the 4 eggs into a small bowl and add them one at a time, beating well after each. The batter may look wet and slightly curdled at this point. That is normal. Beat in the 2 tablespoons lemon zest, 1/4 cup lemon juice, and 1 teaspoon vanilla just until combined.
Switch to a spatula and give the bowl a few turns by hand to catch any streaks. The lemon scent will be strong and fresh. This is where the cake gets most of its citrus flavor.
Step 3: Alternate the Dry Mix and Buttermilk
Whisk the 3 cups flour, 1/2 teaspoon baking soda, and 1/2 teaspoon salt together in a separate bowl. With the mixer on low, add the flour mixture in three parts, alternating with the 1 cup buttermilk in two parts. Start and end with dry. Mix only until the flour disappears each time, no longer than that.
Overmixing at this stage activates gluten and makes the crumb tough. A few small lumps are fine. Scrape the bowl and fold everything gently by hand one last time to make sure no pockets of flour sit at the bottom.
Step 4: Bake the Cake
Preheat the oven to 325°F (165°C). Grease a 9 by 5 inch loaf pan and line it with parchment paper so the ends hang over the long sides. Scrape the batter into the pan and smooth the top. Bake for 60 to 70 minutes, until a toothpick poked into the center comes out with just a few moist crumbs clinging to it.
The top will be deep golden and split down the middle. That crack is a classic pound cake look and means the inside is properly set. If the top browns too fast before the center is done, tent it loosely with foil after the 50-minute mark.
Step 5: Glaze and Serve
Let the cake cool in the pan for 10 minutes, then lift it out by the parchment and place it on a wire rack set over a baking sheet. Stir the 1 cup powdered sugar with 2 tablespoons lemon juice until smooth. Add the last tablespoon of juice only if needed to make a thick but pourable glaze. Spoon the glaze over the warm cake so it drips down the sides.
Cool completely before slicing, or the slices will crumble. The glaze will set into a shiny, slightly crackly shell. Slice thick pieces and serve at room temperature.
Tips for a Perfect Pound Cake
- Bring all the cold ingredients (butter, eggs, buttermilk) to room temperature before you start. Cold ingredients do not blend smoothly and can make the batter seize.
- Measure the flour by spooning it into the cup and leveling it with a knife. Scooping straight from the bag packs in too much flour and leads to a dry cake.
- Do not skip the parchment sling. The cake is heavy and might stick to the pan even with greasing.
- Check for doneness with a toothpick rather than just the clock. Oven temperatures vary, and a dense butter cake can look done on the outside while the center is still raw.
Bake times by pan type:
| Pan | Size | Bake Time |
|---|---|---|
| Loaf pan | 9 x 5 inches | 60 to 70 mins |
| Bundt pan | 10-cup | 50 to 60 mins |
| Mini loaves | 3 x 5 inches | 30 to 35 mins |
Storing Leftover Pound Cake
- Refrigerate: wrap the cooled cake tightly in plastic wrap or keep it in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to one week.
- Reheating: a short 10-second zap in the microwave warms a slice just enough to soften the crumb. You can also toast it lightly and spread with butter.
What to Serve With Lemon Buttermilk Pound Cake
Fresh berries and a dollop of lightly sweetened whipped cream cut through the cake’s richness and add a juicy pop. For a more relaxed afternoon treat, a mug of strong black tea or a short pour of cold milk rounds out the citrus in a cozy way.
Frequently Asked Questions
Can I use regular milk if I don’t have buttermilk?
Yes, but the texture will be slightly less tender. Stir 1 tablespoon of lemon juice or white vinegar into 1 cup whole milk and let it sit 5 minutes to sour it first.
Why did my pound cake turn out dry?
The most common cause is too much flour. Spoon and level your measuring cup instead of scooping, and check the cake a few minutes before the bake time is up.
Can I make this cake gluten-free?
You can, but a one-to-one gluten-free flour blend works best. Choose one that contains xanthan gum. The crumb will be a little more delicate, so handle the cake gently when turning it out.
How can I tell when the cake is fully baked without a toothpick?
A thin metal skewer works the same way. You can also use an instant-read thermometer: the center should register between 200°F and 205°F (93°C and 96°C).
