Lemon Blueberry Pound Cake combines a dense, buttery crumb with sour cream, fresh lemon juice, two kinds of lemon flavoring, and pockets of blueberries. A simple lemon glaze adds a bright finish after the Bundt cake has cooled.
The recipe serves 15 and takes about 90 minutes. Fresh berries usually place the bake within 60 to 70 minutes, while frozen berries can extend it to 70 to 85 minutes. Room-temperature eggs, properly softened butter, and patient creaming produce the most even crumb.
Lemon Blueberry Pound Cake Ingredients
For the cake, use 3 sticks softened unsalted butter, 3 cups sugar, 5 room-temperature eggs, 3 cups flour, ½ teaspoon baking powder, ½ teaspoon salt, 1 cup sour cream, ¼ cup fresh lemon juice, zest of 1 lemon, 1 teaspoon vanilla, 2 teaspoons lemon extract, and 1½ cups fresh or frozen blueberries.
For the glaze, sift 1 cup powdered sugar and combine it with 1 to 2 tablespoons lemon juice, zest of 1 lemon, and a pinch of salt.

How to Make Lemon Blueberry Pound Cake
- Heat the oven to 325°F. Thoroughly grease and flour a Bundt pan.
- Whisk the flour, baking powder, and salt together.
- Cream softened butter and sugar for 3 to 5 minutes, until pale and fluffy. Beat in the eggs one at a time.
- In another bowl, combine sour cream, ¼ cup lemon juice, lemon zest, vanilla, and lemon extract.
- Add the dry mixture in three parts and the sour-cream mixture in two parts, beginning and ending with flour. Mix only until combined.
- Gently fold in 1½ cups blueberries. Transfer the batter to the pan and level it.
- Bake 60 to 70 minutes with fresh berries or 70 to 85 minutes with frozen berries. Cool in the pan 10 to 15 minutes, then invert onto a rack and cool completely.
- Whisk the glaze ingredients until smooth and drizzle over the cooled cake.

Prepare the Bundt Pan Carefully
A detailed Bundt shape needs complete coverage. Brush softened butter or baking spray into every groove, including the center tube, then dust with flour and tap out the excess. Any bare patch can hold the finished cake in the pan.
Prepare the pan before mixing so the batter can go into the oven promptly. Heat the oven fully to 325°F; pound cake is dense, and a stable moderate temperature lets the center cook without making the outside excessively dark.

Cream Butter and Sugar Fully
Beat the three softened sticks of butter with three cups sugar for 3 to 5 minutes. The mixture should look lighter in color and noticeably fluffy. This step incorporates tiny air pockets that help lift a batter built from a substantial amount of butter and sugar.
Add the five room-temperature eggs one at a time, letting each disappear before adding the next. Eggs blend more evenly when they are not cold. Scrape the bowl as needed so no dense butter remains at the bottom.
Alternate the Wet and Dry Mixtures
Whisk flour, baking powder, and salt separately. In a second bowl, combine sour cream with lemon juice, lemon zest, vanilla, and lemon extract. Keeping these mixtures organized makes the alternating sequence easy to follow.
Add flour in three portions and the sour-cream mixture in two, beginning and ending with flour. Mix briefly after each addition. This controlled method keeps the batter emulsified and limits gluten development, protecting the tender but substantial pound-cake texture.
Fold in Blueberries Gently
Use a flexible spatula to fold 1½ cups blueberries through the finished batter. Turn the bowl and lift batter from the bottom rather than stirring vigorously. This preserves the air created during creaming and reduces crushed berries.
Fresh or frozen berries both work. If using frozen, fold them in while frozen and expect the longer baking range. Transfer the thick batter evenly around the Bundt pan and smooth the top so the cake rises to a consistent height.
Test the Cake Without Overbaking
Begin checking at 60 minutes with fresh berries or 70 minutes with frozen. A tester inserted into a thick section should emerge without wet batter; a few moist crumbs are acceptable. The top should spring back lightly and the edges may begin to pull from the pan.
Do not use surface color alone because Bundt pans and ovens brown differently. Once done, let the cake stand in its pan for 10 to 15 minutes. This is long enough for structure to set but not so long that cooling sugars glue it to the pan.
Invert, Cool, and Glaze
Place a rack over the pan and invert confidently. If needed, tap the pan lightly, but do not pry through the decorative crust. Leave the cake undisturbed until completely cool; glaze applied to a warm cake will melt and soak in rather than forming a visible finish.
Whisk sifted powdered sugar with one tablespoon lemon juice, the zest, and a pinch of salt. Add the second tablespoon gradually only if needed for a drizzleable consistency. Spoon the glaze over the crown and let it follow the Bundt ridges naturally.
Serving and Storage
Use a serrated knife to cut 15 slices after the glaze has set. The cake is rich enough to serve without another topping, and its lemon flavor is especially pleasant with coffee or tea. Clean the knife between slices for neat blueberry-streaked portions.
Store the cake covered at room temperature for up to two days or refrigerate it for up to five days. Bring chilled slices toward room temperature before serving so the butter-softened crumb regains its best texture.
Avoid These Pound Cake Mistakes
Cold butter will not cream properly, and melted butter cannot hold the needed air. Adding eggs too quickly can split the mixture. Overmixing after flour enters can toughen the cake, while glazing before the cake cools makes the finish disappear.
Follow the exact 325°F temperature and the correct berry-specific time range. A well-prepared pan, measured ingredients, and staged mixing do more for a reliable release and even crumb than changing the flour or adding unlisted leavening.
Conclusion
Cream three sticks butter and three cups sugar for 3 to 5 minutes, add five eggs one at a time, then alternate the dry mixture with the lemon-sour-cream mixture. Fold in 1½ cups blueberries, bake at 325°F according to the fresh or frozen berry range, cool, and drizzle with lemon glaze.
Frequently Asked Questions
- → Can I use frozen blueberries?
Yes. Fold them in while frozen and expect a 70-to-85-minute bake instead of the 60-to-70-minute fresh-berry range.
- → How long should butter and sugar be creamed?
Cream them for 3 to 5 minutes, until pale and fluffy.
- → When can I remove the cake from the Bundt pan?
Cool it in the pan for 10 to 15 minutes, then invert it onto a rack.
- → Should the cake be warm when glazed?
No. Let it cool completely so the lemon glaze stays visible instead of melting into the cake.
