There is something so joyful about slicing into a soft, sunny Lemon Blueberry Cake and seeing those little bursts of blueberries tucked inside. The crumb is tender and moist, the flavor bright and fresh, and that creamy mascarpone frosting makes every bite feel special.
I have made this lemon blueberry cake more times than I can count, especially in spring and early summer when berries are at their sweetest. It is the kind of homemade dessert that looks impressive but feels completely doable. Ready to bake something beautiful? Let's get cooking.

Ingredients
For the Cake
- 2 cups (380 g) granulated sugar
- ½ cup (118 ml) vegetable oil
- 3 large eggs, room temperature
- 2 lemons, zested and juiced
- 1 teaspoon lemon or vanilla extract
- ½ cup (118 ml) light sour cream
- 2 ½ cups (350 g) all-purpose flour
- 3 teaspoons baking powder
- 1 teaspoon salt
- 1 cup (236 ml) buttermilk
- ¼ cup (59 ml) fresh lemon juice
- 9 ounces fresh blueberries, washed and dried
- 2 tablespoons all-purpose flour, for tossing berries
For the Mascarpone Frosting
- 2 ¼ cups (532 ml) heavy whipping cream, very cold
- 1 cup (130 g) powdered sugar
- 1 teaspoon pure vanilla extract
- 16 ounces mascarpone cheese, cold
- 1 jar (10 ounces) lemon curd
Ingredient Notes & Substitutions
- Sour cream: You can swap this with plain full-fat yogurt. I have tried both, and they each give a lovely moist crumb.
- Buttermilk substitute: No buttermilk? Add 1 tablespoon lemon juice or vinegar to 1 cup milk and let it sit for 5 minutes.
- Frozen blueberries: You can use them straight from the freezer. Do not thaw and skip the flour coating, as frozen berries release more moisture.
- Lemon curd: Store-bought works beautifully here. If you want to make your own, check out this helpful guide to lemon curd basics from a trusted baking resource like King Arthur Baking.
Instruction
- Preheat your oven to 350°F. Line three 8-inch round cake pans with parchment and lightly grease the sides.
- In a large bowl, beat the sugar, oil, eggs, and extract on medium speed for about 2 minutes. The mixture should look lighter and slightly fluffy.
- Zest both lemons directly into the bowl, then add ¼ cup fresh lemon juice and the sour cream. Mix until smooth and creamy. The batter will smell bright and citrusy already.
- In a separate bowl, whisk together flour, baking powder, and salt.
- Add half the dry ingredients to the batter. Mix on low while pouring in half the buttermilk. Stir just until combined.
- Add the remaining dry ingredients and buttermilk. Mix gently until the batter looks smooth. Scrape the bowl to make sure everything is blended from bottom to top.
- Toss the blueberries with 2 tablespoons flour. This keeps them from sinking. Gently fold them into the batter, saving a small handful for the tops.
- Divide the batter evenly between the pans, about 1 ⅔ cups per pan. Scatter the remaining berries over each layer.
- Bake for 20 to 23 minutes, rotating the pans halfway through. The tops should look lightly golden and spring back when touched. A toothpick in the center should come out clean.
- Let the cakes cool completely before frosting. I promise, this patience pays off.
Make the Frosting
- Chill your mixing bowl and whisk for 5 to 10 minutes. Cold tools help the cream whip beautifully.
- Beat the cold mascarpone on medium-low. Slowly pour in the heavy cream and mix until smooth.
- Increase to high speed and whip until soft peaks form.
- Add powdered sugar and vanilla. Beat again until stiff peaks hold their shape. The frosting should look thick, smooth, and cloud-like.
Pro Tips for Success
- Use room temperature eggs for a smoother batter.
- Do not overmix once the flour is added. Gentle mixing keeps the cake tender.
- Tossing berries in flour really helps distribute them evenly.
- Chill the frosting bowl. Cold cream whips faster and holds its shape better.
- Rotate pans halfway for even baking.
Storage and Reheating
Store the frosted cake in the refrigerator in an airtight cake carrier for up to 2 days.
For best flavor and texture, let slices sit at room temperature for about 20 minutes before serving.
Make Ahead & Freezing
You can bake the cake layers in advance. Once completely cool, wrap them tightly in plastic wrap with parchment on the top and bottom. Refrigerate for up to 2 days or freeze for up to 1 month.
I do not recommend making the mascarpone frosting ahead and storing it separately. It is best whipped fresh before frosting.
Tips and Variations
- Swap blueberries for raspberries or blackberries for a slightly deeper berry flavor.
- Add a touch of almond extract for a subtle twist.
- Turn this into cupcakes and reduce baking time to about 15 to 18 minutes.
- For a lighter version, use Greek yogurt instead of sour cream.
- Garnish with edible flowers for a brunch-worthy presentation.
FAQs
Yes, use them straight from the freezer and fold gently into the batter. Skip coating them in flour.
The oil, sour cream, and buttermilk create a tender crumb that stays soft even after chilling.
Absolutely. Divide the batter between two pans and increase the baking time slightly.
