This lemon blueberry pound cake delivers that perfect dense, buttery texture that makes traditional pound cakes so beloved, while the sour cream creates incredible moisture and richness throughout. The bright lemon flavor gets studded with bursts of sweet blueberries in every slice, and that simple lemon glaze adds just enough sweetness without overwhelming the cake itself. What makes this recipe particularly reliable is how the sour cream keeps everything tender for days, making it perfect for baking ahead when you need dessert that actually improves with time.
My grandmother made pound cakes her entire life, but her versions always seemed dry to me until I discovered this sour cream technique. The addition of that tangy dairy transforms everything, creating moisture that lasts through multiple days of storage. After perfecting this recipe, it became my standard contribution to family gatherings because it travels well and actually tastes better the day after baking when all the flavors meld together.
Quality Ingredient Selection
- Real butter: use good quality unsalted butter for the best flavor and texture
- Full-fat sour cream: provides richness and acidity that makes the crumb tender
- Room temperature eggs: incorporate more smoothly and create better structure
- Fresh lemon juice and zest: delivers authentic citrus brightness that bottled juice cannot match
- All-purpose flour: cake flour would be too delicate for this dense pound cake style
- Fresh or frozen blueberries: both work well, though frozen may need slightly longer baking time

Complete Baking Process
- Pan Preparation:
- Preheat your oven to 325°F. Prepare a bundt pan by greasing it thoroughly with butter or cooking spray, then dusting with flour and tapping out the excess. Ensure all ingredients, especially eggs, are at room temperature.
- Dry Ingredient Preparation:
- Whisk together the all-purpose flour, baking powder, and salt for about 30 seconds to distribute everything evenly.
- Creaming Method:
- Add the softened butter to your mixer bowl and cream it with the paddle attachment until smooth. Gradually add the sugar and continue beating for 3-5 minutes until the mixture becomes light, fluffy, and pale in color.
- Egg Integration:
- Add the eggs one at a time, beating after each addition just until the yellow yolk disappears. Scrape down the bowl sides to ensure even incorporation.
- Wet Ingredient Combining:
- In a separate bowl, combine the sour cream, lemon juice, lemon zest, vanilla extract, and lemon extract, stirring until well mixed.
- Alternating Method:
- With your mixer on low speed, add the flour mixture (in three additions) and sour cream mixture (in two additions) alternately to the butter mixture, beginning and ending with flour. Mix just until each disappears.
- Berry Addition:
- Gently fold the blueberries into the finished batter using a spatula. If using frozen blueberries, do not thaw them first.
- Baking to Perfection:
- Pour the batter into your prepared bundt pan. Bake at 325°F for 60-70 minutes (fresh berries) or 70-85 minutes (frozen berries). Test doneness by inserting a toothpick into the thickest part—it should come out clean or with just a few moist crumbs.
- Cooling Process:
- Let the cake cool in the pan for about 10-15 minutes, then carefully invert it onto a wire rack to cool completely.
Simple Lemon Glaze
- Creating the Glaze:
- Sift the powdered sugar into a small bowl. Add 1 tablespoon of fresh lemon juice and a pinch of salt, stirring until the consistency is smooth and thick enough to cling to the cake.
- Application Technique:
- Drizzle the glaze over the completely cooled cake, letting it run down the sides naturally. Sprinkle fresh lemon zest over the wet glaze for color and extra lemon flavor.
The biggest mistake I made early on was rushing the creaming process because I thought 3-5 minutes seemed excessive. My baking teacher explained that proper creaming incorporates the air that creates tender texture, and skipping this step results in heavy, dense cakes. Taking the time for each step properly has transformed all my baking results.
Creative Flavor Variations
Transform this into a raspberry lemon version by substituting raspberries for the blueberries. For chocolate lovers, add chocolate chips instead of berries and use vanilla glaze. A lime version works beautifully by substituting lime juice and zest for the lemon. During fall, try cranberries with orange zest for seasonal flavors.
Storage and Freshness
Store this pound cake covered at room temperature for up to five days, or refrigerated for up to one week. The flavor actually improves after a day as the lemon permeates throughout. Wrap individual slices tightly and freeze for up to three months for quick desserts anytime.

Frequently Asked Questions
- → Can I use frozen blueberries instead of fresh?
- Yes! Frozen blueberries work great but will increase baking time by 10-15 minutes or more. Start checking at 70 minutes and adjust as needed.
- → Why does my pound cake have a dome or crack on top?
- This is normal for pound cakes! The dome and crack are characteristic of a properly baked pound cake and don't affect the flavor or texture.
- → How do I prevent the cake from sticking to the bundt pan?
- Grease the pan thoroughly with butter or shortening, then dust with flour. Make sure to get into all the crevices. Let the cake cool 10-15 minutes before turning out.
- → Can I make this cake ahead of time?
- Yes! The cake actually tastes better the next day as the flavors develop. Store wrapped at room temperature for 2-3 days, or refrigerate for up to a week.
- → What makes this pound cake so moist?
- The sour cream is the secret! It adds moisture, creates a tender crumb, and gives the cake a rich, velvety texture that stays moist for days.
- → How do I know when the cake is done?
- Insert a toothpick or skewer into the center. It should come out clean or with just a few moist crumbs attached. The cake should also pull away slightly from the sides of the pan.
