🛒 Ingredients
Lemon Pound Cake
- 1 cup (2 sticks) unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs, room temperature
- 3 cups all-purpose flour
- ½ teaspoon baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 cup sour cream or buttermilk, room temperature
- ⅓ cup fresh lemon juice
- Zest of 2 lemons
- 2 teaspoons vanilla extract
Blueberry Swirl
- 1½ cups blueberries, fresh or frozen
- ¼ cup granulated sugar
- 1 tablespoon lemon juice
- 1 teaspoon cornstarch
- 1 tablespoon water
Lemon Glaze
- 1 cup powdered sugar
- 2–3 tablespoons lemon juice or blueberry juice
- Fresh blueberries, for garnish
👩🍳 Instructions
1. Prepare the Pan
Preheat your oven to 325°F (165°C). Generously grease and flour a 10–12 cup Bundt pan, making sure to coat all the grooves well.
2. Make the Blueberry Swirl
Add the blueberries, sugar, and lemon juice to a small saucepan over medium heat. Cook for about 5 minutes, stirring occasionally, until the berries burst and release their juices.
Mix the cornstarch with 1 tablespoon of water to make a slurry. Stir it into the blueberries and cook for another 1–2 minutes, until the mixture thickens.
Remove from the heat and allow the blueberry mixture to cool completely.
3. Prepare the Cake Batter
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large bowl, beat the softened butter and sugar for 3–5 minutes, until light and fluffy.
Add the eggs one at a time, beating well after each addition. Mix in the lemon zest and vanilla extract.
On low speed, add the dry ingredients alternately with the sour cream and lemon juice. Mix just until combined. Be careful not to overmix the batter.
4. Layer and Swirl
Pour about one-third of the batter into the prepared Bundt pan.
Dollop half of the cooled blueberry mixture over the batter. Use a knife to gently swirl the blueberry mixture into the cake batter.
Add another one-third of the cake batter, followed by the remaining blueberry mixture. Finish with the remaining batter and gently smooth the top.
Don’t over-swirl—the distinct ribbons of blueberry are what create the beautiful marbled effect.
5. Bake
Bake for 60–75 minutes, or until a toothpick inserted into the thickest part of the cake comes out clean or with a few moist crumbs.
Let the cake cool in the pan for 15–20 minutes, then carefully invert it onto a wire rack to cool completely.
6. Make the Glaze
In a small bowl, whisk together the powdered sugar and 2–3 tablespoons of lemon juice or blueberry juice until smooth and pourable.
Drizzle the glaze over the completely cooled cake. Finish with fresh blueberries for a beautiful presentation.
⭐ Tips for Success
- Use room-temperature ingredients: Butter, eggs, and sour cream blend more easily and help create a smoother batter.
- Don’t overmix: Once the flour is added, mix only until everything comes together.
- Cool the blueberry sauce: Hot blueberry filling can make the batter difficult to layer and swirl.
- Prepare the Bundt pan well: Grease every groove generously to make releasing the cake easier.
- Don’t over-swirl: A few gentle passes with a knife create attractive blueberry ribbons without blending the colors together.
- Let the cake cool completely: This helps the glaze stay on top instead of melting into the cake.
🍽️ Serving Suggestions
Serve this pound cake in thick slices with a cup of coffee or tea. For an extra-special dessert, add a spoonful of whipped cream or a scoop of vanilla ice cream alongside each slice.

🧊 Storage
Store the cooled cake in an airtight container at room temperature for up to 2 days, or refrigerate it for longer storage. If refrigerated, let slices sit at room temperature for a few minutes before serving for the best texture.
