Why This Recipe Works

This cake balances richness with brightness. Butter and sour cream create a tight, velvety crumb, while fresh lemon zest and juice cut through with gentle tang. Tossing blueberries in flour helps keep them from sinking, so you get even pops of fruit throughout each slice.

A quick lemon glaze seals in moisture and adds a glossy finish. The method is straightforward, and the results feel bakery-level without the fuss.

What You’ll Need

All-purpose flour – The base for structure and a tender crumb.
Baking powder – For lift without making the cake airy or spongey.
Fine sea salt – Enhances flavor and balances sweetness.
Unsalted butter, room temperature – For buttery flavor and softness.
Granulated sugar – Sweetness and structure through creaming.
Large eggs, room temperature – Bind the batter and add richness.
Sour cream, room temperature – Moisture and a tender crumb.
Whole milk – Smooths the batter without thinning it too much.
Fresh lemon zest – Big, bright lemon flavor.
Fresh lemon juice – Tang and balance.
Vanilla extract – Rounds out the citrus and blueberry.
Fresh blueberries (or frozen, unthawed) – The star mix-in.
Powdered sugar – For the glaze.

Pan: 9×5-inch loaf pan or a 10-cup bundt pan. Grease well and line the loaf pan with a parchment sling for easy removal.

Prep the pan and oven. Heat the oven to 350°F (175°C).
Grease your loaf or bundt pan thoroughly. If using a loaf pan, line it with a parchment sling so you can lift the cake out cleanly.
Combine dry ingredients. In a medium bowl, whisk 2 cups (240 g) all-purpose flour, 1 1/2 teaspoons baking powder, and 1/2 teaspoon fine sea salt. Set aside.
Beat butter and sugar. In a large bowl, beat 1 cup (226 g) unsalted butter with 1 cup (200 g) granulated sugar on medium-high until pale and fluffy, about 3 minutes.
This step creates lightness and a fine crumb.
Add eggs. Beat in 4 large eggs one at a time, mixing well after each addition and scraping the bowl. The batter should look smooth and slightly thick.
Flavor the batter. Mix in 2 teaspoons vanilla extract, the zest of 2 lemons (about 2 tablespoons), and 2 tablespoons fresh lemon juice. The aroma should be bright and citrusy.
Mix in sour cream and milk. Add 1/2 cup (120 g) sour cream and 2 tablespoons whole milk.
Beat on low just until smooth. Don’t worry if it looks slightly curdled at this point; the flour will bring it together.
Fold in dry ingredients. Sprinkle the flour mixture over the wet ingredients and fold gently with a spatula until just combined. Avoid overmixing to keep the crumb tender.
Prepare blueberries. In a small bowl, toss 1 1/2 cups blueberries with 1 tablespoon flour.
This helps suspend them in the batter. If using frozen berries, do not thaw; toss quickly and proceed.
Fold in blueberries. Gently fold the berries into the batter, leaving any excess flour in the bowl. Aim for even distribution without smashing the fruit.
Fill the pan and smooth. Scrape the batter into the prepared pan.
Smooth the top with a spatula and tap the pan lightly on the counter to release air bubbles.
Bake. Bake for 55–70 minutes for a loaf, or 45–60 minutes for a bundt, until the top is golden and a toothpick comes out with a few moist crumbs (not wet batter). If browning too quickly, tent loosely with foil.
Cool. Let the cake cool in the pan for 15–20 minutes, then transfer to a wire rack to cool completely. This prevents a gummy texture and helps the glaze set later.
Make the glaze. In a small bowl, whisk 1 cup (120 g) powdered sugar with 1–2 tablespoons fresh lemon juice until thick but pourable.
For extra tang, add a pinch of lemon zest or a drop of vanilla to soften the edge.
Glaze and set. Pour the glaze over the cooled cake, letting it drip down the sides. Allow 15–20 minutes for the glaze to set before slicing.
Slice and serve. Use a sharp, serrated knife. Wipe the blade between cuts for clean slices with intact blueberries.

Keeping It Fresh

Room temperature: Store the glazed cake in an airtight container for up to 3 days.

The glaze helps lock in moisture.

Refrigerator: If your kitchen is warm or humid, refrigerate up to 5 days. Bring slices to room temperature before serving for the best texture.

Freezer: Wrap unglazed slices tightly in plastic and place in a freezer bag for up to 2 months. Thaw at room temperature, then glaze before serving.

Benefits of This Recipe

Reliably moist. Sour cream and butter deliver that classic pound cake tenderness.
Balanced flavor. Lemon brightens without overwhelming, and the berries add natural sweetness.
Simple pantry ingredients. No special equipment or hard-to-find items.
Make-ahead friendly. Tastes even better the next day as flavors meld.
Flexible format. Works in a loaf or bundt pan, with fresh or frozen berries.

Pitfalls to Watch Out For

Cold ingredients. Butter, eggs, and sour cream should be at room temperature, or the batter may look split and bake unevenly.
Overmixing. Stir just until combined after adding flour.
Overworking the batter can make the cake dense or tough.
Blueberries sinking. Toss berries in flour and don’t over-stir. Pour half the batter in the pan, sprinkle some berries, then repeat if you struggle with sinking fruit.
Underbaking. A gummy streak in the center means it needed more time. Check in multiple spots and look for a golden top and set edges.
Glazing too soon. If the cake is warm, the glaze will melt and slide off.
Cool fully for a neat finish.

Recipe Variations

Lemon Almond: Replace 1/2 teaspoon vanilla with 1/2 teaspoon almond extract. Top with sliced toasted almonds after glazing.
Triple Citrus: Use a mix of lemon, lime, and orange zest (about 2 tablespoons total) and swap half the lemon juice with orange juice in the glaze.
Lemon Poppy Seed Blueberry: Add 1 tablespoon poppy seeds to the dry ingredients for a subtle crunch.
Gluten-Free: Use a cup-for-cup gluten-free flour blend with xanthan gum. Let the batter rest 10 minutes before baking to hydrate.
Yogurt Swap: Replace sour cream with full-fat Greek yogurt for a slightly tangier crumb.
Streusel Top (Loaf only): Combine 1/4 cup flour, 1/4 cup brown sugar, 2 tablespoons cold butter, and a pinch of salt.
Crumble over the batter before baking for a crisp top.

Can I use frozen blueberries?

Yes. Use them straight from the freezer and toss lightly with flour. Fold in gently and bake immediately.

They may streak the batter a bit, but the cake will taste just as good.

How do I know when the cake is done?

Look for a deep golden top, edges pulling slightly from the pan, and a toothpick that comes out with a few moist crumbs. If the center still looks glossy or the tester is wet, give it more time and tent with foil if needed.

Can I make this in advance?

Absolutely. The flavor improves after a day.

Bake, cool, and store at room temperature, then glaze the day you plan to serve. Slices reheat well in a low oven for a few minutes if you like them slightly warm.

What if I don’t have sour cream?

Use full-fat Greek yogurt. The texture stays moist and tender, and the flavor is slightly tangier.

Avoid low-fat swaps, which can make the cake drier.

Why did my blueberries sink?

Likely the batter was too loose or the berries weren’t coated in flour. Make sure your butter and sugar are well-creamed, don’t over-add liquid, and gently fold in flour-dusted berries. Layering some berries in the middle can also help.

Can I reduce the sugar?

You can reduce granulated sugar to 3/4 cup without major texture issues.

The cake will be a bit less tender and brown slightly less, but it still works. Keep the glaze as written to maintain balance.
