Ingredients You’ll Need

1 cup fresh blueberries or frozen: Fresh blueberries are recommended for their delicious flavor, but frozen works well too—just thaw them first!
Zest and juice of 1 lemon: Provides the essential bright flavor. Use a microplane for zesting for the best results.
2 whole eggs & 2 egg yolks: These create structure and richness. Save the whites for the cake.
1 cup granulated sugar: Sweetens the curd beautifully. You can use coconut sugar for a lighter option.
½ cup salted butter, cut into small cubes: Adds creaminess to the curd. Unsalted butter can be substituted if desired.
4 cups cake flour: For a light, fluffy cake. All-purpose flour can work, but cake flour gives the best texture.
1 tablespoon baking powder: Helps the cake rise.
1 teaspoon baking soda: Assists in achieving that light, airy texture.
1 teaspoon salt: Enhances flavors.
3 tablespoons lemon zest: Infuses even more lemon flavor into the cake.
2 ½ cups granulated sugar: Sweetens the cake. Again, coconut sugar can add unique flavor.
½ cup salted butter, room temperature: Ensures the cake batter mixes easily and evenly.
1 cup oil (I used avocado oil): Keeps the cake moist; can use canola or vegetable oil too!
4 large eggs, room temperature: Guarantees a smooth batter.
2 egg whites, room temperature: Leftover from the curd—adds lightness.
2 teaspoons lemon extract: Intensifies lemon flavor.
2 teaspoons vanilla extract: Balances the citrus with sweetness.
½ teaspoon almond extract: Adds a subtle depth. Omit if you’re not a fan.
¾ cup sour cream, room temperature: Contributes moisture and tang.
1 cup buttermilk, room temperature: Helps create a tender crumb.
⅓ cup lemon juice, room temperature: Brightens the flavor profile.
1 cup salted butter, room temperature: For the creamy frosting, can also use unsalted butter.
4 cups powdered sugar: Sweetens the frosting. For a less sweet option, try using half.
2 teaspoons vanilla extract: Enhances overall flavor.
2 tablespoons lemon juice: Adds brightness to the frosting.
16 oz cream cheese: Forms the base of the creamy, luscious frosting.

How to Make Lemon Cake with Blueberry Curd

Prepare the Blueberry Curd: Start by adding 1 cup of blueberries and ⅓ cup lemon juice to a small saucepan over medium heat. Simmer gently for about 5 minutes until the blueberries burst and create a beautiful jam-like consistency. Mash the blueberries a bit and strain through a fine mesh to remove seeds for a smooth curd.
Cook the Curd Mixture: Add 2 whole eggs, 2 egg yolks, and 1 cup granulated sugar to a medium heat-safe bowl. Whisk in the reserved blueberry mixture and place this bowl over a saucepan with about 2 inches of simmering water to create a double boiler. Stir continuously until it thickens, about 10-15 minutes. Once it’s pudding-like, remove from heat and stir in the cut butter until melted. Cover with plastic wrap and chill in the fridge.
Preheat and Prepare Pans: While the curd cools, preheat your oven to 325 degrees F. Grease and lightly flour two 8-inch cake pans.
Mix the Sugar and Lemon Zest: In a large bowl, combine the zest of 3 lemons and 2 ½ cups granulated sugar. Rubbing the zest into the sugar with your fingers releases essential oils for rich lemon flavor.
Cream the Butter and Oil: Add ½ cup room temperature butter and 1 cup oil to the sugar mixture. Beat on medium speed for about 4 minutes until light and fluffy, scraping down the sides halfway through.
Add Wet Ingredients: Mix in the 4 large eggs, 2 egg whites, ¾ cup sour cream, 2 teaspoons lemon extract, 2 teaspoons vanilla extract, and ½ teaspoon almond extract until just combined.
Combine Dry Ingredients: In a separate bowl, whisk together 4 cups cake flour, 1 teaspoon baking soda, 1 tablespoon baking powder, and 1 teaspoon salt.
Mix Cake Batter: Gradually add half of the dry mixture to the wet ingredients and mix lightly. Then add 1 cup buttermilk and ⅓ cup lemon juice until combined. Follow with the remaining dry ingredients, mixing just until incorporated.
Bake: Divide the cake batter evenly between the prepared pans. Bake for about 40-45 minutes or until a toothpick inserted in the center comes out clean. Allow cakes to cool in the pans for 10 minutes before transferring to wire racks to cool completely.
Make the Cream Cheese Frosting: In a large bowl (a stand mixer works wonders here), beat together 1 cup room temperature butter and 16 oz cream cheese on low speed until combined, about 1-2 minutes. Gradually add in 4 cups powdered sugar, 2 tablespoons lemon juice, and 2 teaspoons vanilla extract—start on low, then once combined, increase to medium and beat for 5-10 minutes until light and creamy.
Assemble the Cake: Place one cooled cake layer on a serving plate. Create a border of frosting around the edge and fill the center with your blueberry curd. You might have some extra curd—try not to eat it by the spoonful!
Add the Second Layer: Carefully place the second cake layer on top and then apply a thin layer of cream cheese frosting around the cake for a “crumb coat.” Chill it in the fridge for about 30 minutes to set.
Final Frosting Touches: Once chilled, frost the cake with the remaining cream cheese frosting as desired. Add dollops of blueberry curd for decoration, swirling to give a stunning visual effect.
Serve: Slice the cake and enjoy! Remember to let it sit out at room temperature for about an hour before serving for optimal texture.

Storing & Reheating

To store your Lemon Cake with Blueberry Curd, keep it in an airtight container in the refrigerator for up to 5 days. Before enjoying, let it come to room temperature for about an hour to regain its ideal texture. If you want to prepare it ahead of time, you can freeze it for up to 3 months, just wrap individual slices tightly in plastic wrap and then place them in a freezer-safe bag. When you’re ready, thaw it in the fridge overnight, but keep in mind the texture may change slightly upon reheating.

Chef’s Helpful Tips

Make sure your eggs and dairy are at room temperature for the best results in your batter.
When mixing in the dry ingredients, be careful not to overmix to keep the cake tender and fluffy.
If your curd gets too thick, whisk in a little warm water after it cools down to loosen it.
Use fresh lemon juice for the best flavor—bottled juice can lack the bright freshness.
If possible, bake the cake a day ahead; letting it rest overnight improves flavors and texture.
Consider adding fresh berries on top for an extra pop of color when serving.

Bringing this Lemon Cake with Blueberry Curd to life is not just about following a recipe—it’s about creating joy in every bite. This cake offers a delightful combination of flavors and textures that will brighten any occasion.
