This vibrant lemon blueberry cake delivers a perfect balance of bright citrus and sweet berry flavors in every bite. The Greek yogurt creates an incredibly moist texture while the fresh lemon juice adds a tangy brightness that cuts through the sweetness. Juicy blueberries burst throughout the cake, creating pockets of fruity goodness that complement the lemony base beautifully.
I first made this cake for a springtime gathering and was amazed at how quickly it disappeared. The combination of lemon and blueberry instantly transports me to sunny summer days, and guests always ask for the recipe. Even my father, who typically avoids sweets, requests this cake specifically for family gatherings.
Cake Building Blocks
- All purpose flour: Provides the structure while remaining tender when properly measured
- Baking powder: Creates the perfect rise and light texture throughout the cake
- Granulated sugar: Sweetens while creating moisture when rubbed with lemon zest
- Lemon zest: Contains essential oils that infuse intense citrus flavor throughout
- Greek yogurt: Adds tanginess and creates incredibly moist texture that lasts for days
- Fresh lemon juice: Brightens the flavor with natural acidity that activates the baking powder
- Blueberries: Burst during baking to create pockets of jammy sweetness throughout
- Canola oil: Keeps the cake moist longer than butter while allowing lemon flavor to shine
- Confectioners' sugar: Creates smooth, lump free frosting that sets beautifully on the cake
Baking Procedure
- Oven Preparation:
- Begin by positioning your rack in the center of your oven and preheating to exactly 350°F. Thoroughly grease a 9x2 inch round cake pan, line the bottom with parchment paper, then grease the parchment as well to ensure perfect release after baking.
- Mixing Foundation:
- In a medium bowl, sift together the flour, baking powder, and salt to remove any lumps. In a separate large bowl, place the granulated sugar and add the fresh lemon zest. Using your fingertips, rub the zest into the sugar until fragrant and slightly moist, releasing the essential oils for maximum flavor.
- Creating Batter:
- Whisk together eggs, oil, yogurt, lemon juice, and vanilla in a bowl until completely smooth. Gradually add this wet mixture to your lemon sugar, stirring until well combined. Slowly incorporate the dry ingredients into the wet mixture, stirring just until no flour streaks remain. In a separate small bowl, toss your blueberries with one tablespoon of flour until lightly coated. Gently fold the coated blueberries into the batter with a rubber spatula, taking care not to crush them.
- Baking Process:
- Pour the completed batter into your prepared pan, smoothing the top with a spatula. Place in the preheated oven and bake for 35 to 50 minutes. Begin checking at 35 minutes by inserting a toothpick into the center. The cake is done when the toothpick comes out clean or with a few moist crumbs. Allow the cake to cool in the pan for exactly 20 minutes before carefully removing and transferring to a wire rack to cool completely.

The first time I made this cake, I learned the hard way that rushing the cooling process leads to crumbling. Now I patiently wait those full 20 minutes before removing it from the pan, resulting in perfect slices every time.
Recipe Variations
For a winter version, substitute cranberries for blueberries and orange zest for lemon. Make it gluten free by using a 1:1 baking flour substitute. Create individual portions by baking in muffin tins for 18-22 minutes.
Storage Tips
Store covered at room temperature for up to 3 days or refrigerate for up to 5 days. Freeze unfrosted cake layers wrapped in plastic for up to 2 months. Thaw overnight before frosting and serving.

Frequently Asked Questions
- → Can I use frozen blueberries instead of fresh ones?
- Yes, you can use frozen blueberries! Don't thaw them first - add them to the batter while still frozen after tossing them in flour. This prevents them from sinking and bleeding too much color into the batter.
- → Why do I need to toss the blueberries in flour?
- Tossing blueberries in flour before adding them to the batter helps prevent them from sinking to the bottom of the cake. The flour coating helps the berries 'grip' the batter and stay suspended throughout the cake.
- → Can I make this cake ahead of time?
- Absolutely! The cake can be made 1-2 days in advance. Store it covered at room temperature without the frosting, then add the fresh lemon frosting just before serving for the best flavor and appearance.
- → What can I substitute for Greek yogurt?
- If you don't have Greek yogurt, you can substitute with sour cream in equal amounts. The cake will still be moist and have a similar texture and slight tanginess that complements the lemon.
- → Can I make this cake in a different size pan?
- Yes, you can use different pans, but you'll need to adjust baking times. For two 8-inch rounds, bake for 25-30 minutes. For a 9x13 pan, bake for about 35 minutes. Always check with a toothpick for doneness.
- → How do I store leftover cake?
- Store leftover cake in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. Let refrigerated cake come to room temperature before serving for the best flavor and texture.
