Moist Lemon Blueberry Pound Cake
This lemon blueberry pound cake is tender and buttery, with bursts of juicy berries in every slice. A bright lemon glaze sets over the top, making it feel like a weekend bake even on a Wednesday evening.
The method is straightforward enough that you can mix it by hand if you want, and the batter comes together without a fuss. Just a good, honest cake that works the first time.
What Makes This Pound Cake So Good
I keep coming back to this version because the sour cream does two jobs at once. It adds richness without making the crumb greasy, and that little bit of tang balances the sweet berries and sharp lemon.
Most pound cakes lean heavy. This one still has that classic dense slice, but the crumb stays soft for days. The lemon comes from fresh zest and juice, so it tastes clean, not like extract.
It’s a cake that looks like you tried harder than you actually did. The glaze cracks faintly when you slice it, and the purple berries dot every piece.
Ingredients
- For the cake:
- 1 1/2 cups all-purpose flour: spooned and leveled for accuracy
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 3/4 cup unsalted butter, softened: let it come to room temperature so it creams easily
- 3/4 cup granulated sugar
- 2 large eggs: at room temperature
- 1/2 cup full-fat sour cream: at room temperature
- Zest of 1 lemon: (about 1 tablespoon)
- 2 tablespoons fresh lemon juice
- 1 teaspoon vanilla extract
- 1 cup fresh blueberries: plus 1 tablespoon flour for tossing
- 1 tablespoon all-purpose flour: for coating the blueberries
- For the glaze:
- 1 cup powdered sugar
- 2 to 3 tablespoons lemon juice: add slowly until the glaze is thick but pourable
Variations / Substitutions
- Swap the citrus: use orange zest and juice for a different citrus note. The color will be softer, and the sweetness a little rounder.
- Make it gluten-free: a 1:1 gluten-free flour blend works well here. The crumb may be slightly more tender, but it slices cleanly.
- Go dairy-free: use a plant-based butter stick and a thick, unsweetened dairy-free yogurt in place of the sour cream.
- Bake as muffins: divide the batter into a 12-cup muffin tin and bake 18 to 22 minutes. The tops will dome lightly.

How To Make Lemon Blueberry Pound Cake
Step 1: Cream the Butter and Sugar
Preheat your oven to 350°F (175°C) and line a 9×5-inch loaf pan with parchment paper. In a large bowl, beat the 3/4 cup butter and 3/4 cup sugar with an electric mixer on medium speed until the mixture turns pale and fluffy, about 3 minutes. Add the 2 eggs one at a time, beating well after each addition, then mix in the lemon zest, 2 tablespoons lemon juice, and 1 teaspoon vanilla until smooth.
The batter should look thick and creamy, with a strong lemon scent. Scrape the sides and bottom of the bowl now so no butter clumps hide there.
Step 2: Whisk the Dry Ingredients
In a separate bowl, whisk the 1 1/2 cups flour, 1 teaspoon baking powder, and 1/2 teaspoon salt for about 30 seconds. You want the leavening and salt spread evenly through the flour.
The whisk does the same job as sifting here. The mixture will look uniform with no lumps.
Step 3: Fold in the Dry Ingredients and Blueberries
With the mixer on low, add the flour mixture to the butter mixture in three additions, alternating with the 1/2 cup sour cream. Start and end with the flour. Mix just until the last streak of flour disappears. In a small bowl, toss the 1 cup blueberries with the 1 tablespoon flour, then gently fold them into the batter using a spatula.
The extra flour on the berries helps keep them suspended so they don’t all sink to the bottom. The batter will be thick and dotted with purple.
Step 4: Bake the Cake
Scrape the batter into the prepared pan and smooth the top. Bake for 55 to 65 minutes, until a toothpick inserted in the center comes out with a few moist crumbs clinging to it. A completely clean pick means the cake may be a little dry, so a crumb or two is what you want.
The top will be deeply golden and the whole kitchen will smell like lemon and warm butter. Let the cake cool in the pan for 10 minutes, then lift it out by the parchment and cool completely on a wire rack before you add the glaze.
Step 5: Drizzle the Lemon Glaze
In a small bowl, whisk the 1 cup powdered sugar with 2 tablespoons lemon juice until smooth. Add a few extra drops of juice at a time until the glaze is thick enough to hold a ribbon but pours easily from a spoon. Drizzle it over the completely cooled cake.
The glaze will set into a thin, shiny crust that cracks slightly when you cut a slice. Let it firm up for about 15 minutes, then slice and serve.
A Few Tips Before You Bake
- Bring the butter, eggs, and sour cream to room temperature. Cold ingredients can cause the batter to curdle, and the cake won’t rise as evenly.
- Once the flour goes in, mix gently. Overworking the batter after this point can make the cake tough instead of tender.
- Fresh lemon zest is the main source of flavor here. Bottled juice won’t give you the same brightness, so grab a real lemon.
- Cool the cake completely before glazing. If it’s even slightly warm, the glaze will melt into the top and turn translucent instead of forming that pretty white layer.
- A light-colored metal loaf pan gives the most even browning. Dark pans can over-brown the crust before the center sets.
Keeping the Cake Fresh
Cover the unglazed cake and store it at room temperature for up to 3 days. If the cake is already glazed, store it loosely covered so the glaze doesn’t get sticky. Slices can be frozen for up to a month; defrost at room temperature and glaze after thawing.
Frequently Asked Questions
Can I use frozen blueberries?
Yes, do not thaw them. Toss the frozen berries straight from the freezer with the flour and fold them in gently. Expect to add 5 to 10 minutes to the bake time.
Can I make this in a Bundt pan?
Yes, grease and flour a 10-cup Bundt pan well. Bake for 45 to 55 minutes and start checking early, since the shape changes the timing.
Why did my pound cake sink in the middle?
Usually it’s from underbaking or opening the oven door too early. The center hasn’t set enough to hold its shape. Use the toothpick test and try not to peek before the 40-minute mark.
Can I skip the glaze?
Absolutely. The cake is lovely on its own. A dusting of powdered sugar right before serving works instead.
