Its tender, moist crumb is perfectly balanced with a bright, zesty lemon flavor. Finished with a rich and creamy cream cheese frosting, this is a delightfully fresh and luscious dessert that’s perfect for spring and summertime.
PREPARATION TIME:
- Prep Time: 35 minutes
- Cook Time: 25 minutes
- Total Time: 4 hours
Ingredients
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 1 and 1/4 cups (250g) granulated sugar
- 1/2 cup (100g) packed light brown sugar
- 6 Tablespoons (90ml) vegetable oil, canola oil, or avocado oil
- 4 large eggs, at room temperature
- 1 Tablespoon pure vanilla extract
- 3 cups (375g) all-purpose flour (spooned & leveled)
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 3/4 cup (180ml) buttermilk, at room temperature
- 2 Tablespoons lemon zest
- 1/2 cup (120ml) lemon juice (3–4 lemons), at room temperature1 and 1/2 cups (210g) fresh blueberries (I do not recommend frozen)
- 1 Tablespoon all-purpose flour
Cream Cheese Frosting
- 8 ounces (226g) full-fat brick cream cheese, softened to room temperature*
- 1/2 cup (8 Tbsp; 113g) unsalted butter, softened to room temperature
- 3 and 1/2 cups (420g) confectioners’ sugar
- 1 Tablespoon (15ml) heavy cream*
- 1 teaspoon pure vanilla extract
- pinch salt
Instructions
- Preheat oven to 350°F (177°C). Grease three 8-inch round cake pans, line with parchment paper rounds, then grease the parchment paper. Parchment paper helps the cakes seamlessly release from the pans. (If it’s helpful, see this parchment paper rounds for cakes video & post.)
- Make the cake: Using a handheld or stand mixer with a paddle attachment, beat the butter on high until smooth and creamy, about 1 minute. Add granulated and brown sugars and beat on medium-high speed until combined, about 2 minutes. Add the oil and beat until combined and light and creamy, about 3 more minutes. Add the eggs and vanilla, and beat on medium speed until everything is completely combined, about 1 minute. Scrape down the sides and bottom of the bowl as needed.
- In a large bowl, whisk together the flour, baking powder, baking soda, and salt. Add the dry ingredients to the wet ingredients. Beat on low speed for a few seconds, then beat in the milk, lemon zest, and lemon juice *just* until combined. Toss the blueberries with 1 Tablespoon of flour and gently fold into the batter. Batter is thick. Do not over-mix.
- Spoon batter evenly into prepared cake pans. Bake for about 22–26 minutes or until a toothpick inserted in the center comes out clean. Remove from the oven and allow to cool completely in the pan before assembling and frosting.
- Make the frosting: Using a handheld or stand mixer with a paddle attachment, beat cream cheese and butter together on medium speed until no lumps remain, about 3 full minutes. Add confectioners’ sugar, heavy cream, vanilla extract, and salt with the mixer running on low. Turn mixer up to high speed and beat for 3 minutes.
- Assemble and frost: (Note: See my how to assemble and decorate a layer cake video & tutorial if you want extra help with this step.) First, using a large serrated knife, slice a thin layer off the tops of the cakes to create a flat surface. Place 1 layer on your cake stand. Evenly cover the top with cream cheese frosting. Top with 2nd layer, more frosting, then the third layer. Top with frosting and spread around the sides. The recipe doesn’t make a ton of frosting, just enough for a light frost. Top with blueberries or lemon garnish if desired. Refrigerate for at least 45 minutes before cutting or else the cake may fall apart as you cut.
- Cover leftover cake tightly and store in the refrigerator for up to 5 days.
Notes
- Make Ahead & Freezing Instructions: Prepare cakes and frosting 1 day in advance. Keep cakes at room temperature, covered tightly. Refrigerate prepared frosting in an airtight container until ready to use. Bring frosting to room temperature before spreading as it will be quite stiff after refrigerating. (Add a splash of cream or milk to thin out, if needed.) Frosted or unfrosted cakes may be frozen for up to 2 months; thaw overnight in the refrigerator and bring to room temperature, if desired, before serving.

- Sheet Cake: The batter makes a perfect sheet cake! Simply spread into a 12×17-inch half sheet/jelly roll pan and bake for about 20 minutes or until cooked through. It also fits nicely into a 9×13-inch cake pan. Bake for about 30–35 minutes or until cooked through.
- Bundt Cake: I recommend making my lemon poppy seed Bundt cake recipe. You can leave out the poppy seeds and add 1 and 1/2 cups (210g) fresh blueberries. I also have a lemon berry yogurt cake recipe. You can use all blueberries.
- Cupcakes: Here are my lemon blueberry cupcakes topped with cream cheese frosting.
- 6-Inch Cake: Use my lemon blueberry cupcakes batter and follow my 6-inch cake baking instructions.
- Eggs: Room-temperature eggs are recommended because they mix easily and quickly into the cake batter, reducing the risk of over-mixing. Place eggs into a bowl of warm water for 5 minutes before using or set the eggs out when you set out your cream cheese and butter for the recipe.
- Buttermilk: Buttermilk helps produce a supremely moist cake. If you don’t have buttermilk, use whole milk instead. No need for a buttermilk substitute. You can use lower-fat or nondairy milks in a pinch, but the cake won’t taste nearly as rich and moist.
- Cream Cheese: Use brick-style cream cheese, not cream cheese spread.
- Heavy Cream: Heavy cream with 30% or more milk fat gives the frosting the creamiest texture. Milk will work in a pinch!
