This lemon blueberry cake combines the bright, tangy flavor of fresh lemons with juicy blueberries in a moist, tender cake that's crowned with luscious cream cheese frosting. Each bite delivers the perfect balance of tart citrus and sweet berries in a dessert that's equally perfect for special occasions or weekend baking projects.
I first made this cake for my sister's spring birthday gathering, and it became an instant family classic. The vibrant colors and fresh flavors make everyone feel like they're tasting sunshine on a plate, regardless of the season.
Ingredients
- Cake flour: creates an exceptionally tender crumb that perfectly supports the blueberries
- Buttermilk: adds tanginess and ensures moisture throughout every bite
- Fresh lemon juice and zest: provide bright flavor that complements the berries beautifully
- Room temperature butter: creates a velvety texture when creamed with sugar
- Fresh blueberries: offer bursts of juicy sweetness and stunning color throughout the cake
- Cream cheese: gives the frosting its signature tangy flavor that pairs perfectly with lemon
Step-by-Step Instructions
- Prepare the pans:
- Properly preparing your baking pans is crucial for easy removal later. Take time to thoroughly grease every corner and dust with flour for a 9x13 pan. For layer cakes, parchment paper rounds on the bottom provide extra insurance against sticking.
- Mix dry ingredients:
- Sifting the flour with leavening agents and salt ensures even distribution and prevents lumps. This step might seem fussy but creates a more uniform texture in the finished cake.
- Combine wet ingredients:
- Mixing buttermilk with fresh lemon juice starts a chemical reaction that enhances the tenderness of the cake. Let this mixture sit while preparing other ingredients to maximize effect.
- Cream butter mixture:
- Beat butter, sugar and lemon zest until truly light and fluffy for at least 3 minutes. This creates air pockets that expand during baking for proper rise. The lemon zest releases more flavor when mixed with sugar than when added later.
- Add eggs carefully:
- Adding eggs one at a time allows each to fully incorporate into the batter before adding the next. Scraping down the bowl between additions ensures no butter mixture gets left behind, preventing streaks in the final cake.
- Alternate dry and wet ingredients:
- Using the low speed prevents overmixing while alternating dry and wet ingredients preserves the airy texture. This method prevents the gluten from developing too much which would make the cake tough.
- Prepare blueberries:
- Coating blueberries in a light dusting of flour helps suspend them throughout the batter instead of sinking to the bottom. Fold them in gently to avoid breaking them and creating blue streaks.
- Bake until perfect:
- Watch for visual cues beyond just timing. The cake should spring back when lightly touched and a toothpick should come out clean from the center. The edges will begin to pull away slightly from the pan.

The fresh lemon zest is truly the secret hero of this recipe. I always zest my lemons directly over the butter and sugar mixture to capture every drop of the aromatic oils that live in the yellow part of the peel. These oils contain intense lemon flavor that perfumes the entire cake in a way that juice alone simply cannot achieve.
Choosing the Perfect Lemons
When selecting lemons for this recipe, look for fruits that feel heavy for their size, indicating juiciness. The skin should have a bright yellow color and feel slightly firm but not hard. Before zesting, wash the lemons thoroughly with warm water and dry completely. For maximum juice extraction, roll them firmly on the counter with the palm of your hand before cutting and squeezing.
Why Fresh Blueberries Matter
While it might be tempting to use frozen berries, fresh blueberries truly make this cake exceptional. They hold their shape during baking, creating pockets of juicy fruit throughout rather than bleeding into the batter. Look for plump, firm berries with a dusty blue color. The dusty appearance actually indicates freshness. Avoid any containers with stained bottoms, which signals crushed berries that will likely be mushy.
Make-Ahead Options
This cake offers several convenient make-ahead possibilities. The unfrosted cake layers can be wrapped tightly and refrigerated overnight or frozen for up to two months. The frosting can be prepared a day ahead and stored in the refrigerator. Allow it to come to room temperature and beat briefly before using. For special occasions, consider making the complete cake the day before serving. The flavors actually improve as they meld overnight in the refrigerator.
Frequently Asked Questions About Recipes
- → Can I substitute frozen blueberries for fresh ones?
While fresh blueberries are recommended for the best texture and minimal bleeding, frozen blueberries can be used without thawing. Note that the bake time may increase slightly.
- → What if I don’t have cake flour?
If you don’t have cake flour, you can substitute with all-purpose flour and cornstarch. Replace 2 2/3 cups of all-purpose flour with 2 1/3 cups all-purpose flour and 1/3 cup cornstarch, then sift together three times.
- → How do I prevent blueberries from sinking in the batter?
Toss the blueberries in a small amount of flour before folding them into the batter. This helps them stay evenly distributed during baking.
- → Can I make this cake ahead of time?
Yes, the unfrosted cake layers can be wrapped tightly and stored at room temperature overnight or refrigerated for up to 24 hours. Frost on the day of serving for the freshest result.
- → How can I store leftovers?
Leftovers can be stored in an airtight container in the fridge for up to 4 days. Ensure the frosting does not absorb other fridge odors by sealing the container tightly.
