Ingredients to Make Lemon Blueberry Cake

This cake is a work of art! Anyone can make it as long as you stick to this ingredients list. Check out the recipe card at the bottom of the post for exact measurements.

Cake

Granulated Sugar:
Lemon Zest: You will need the zest from 2 large lemons.
Cake Flour: I used cake flour instead of all purpose flour because it cake it a better texture.
Baking Powder and Baking Soda: These help the cake to rise and get that soft texture.
Salt: This will enhance all of the flavors in the cake.
Buttermilk: If you don’t have any buttermilk on hand, don’t worry! You can make it with only two ingredients using this recipe here.
Lemon Juice: You can use the lemons that you got the zest from for the juice! Fresh is best!
Vanilla: Add a splash of vanilla to enhance the sweet flavors.
Vegetable Oil: If you are wondering what makes a cake moist, this is it!
Egg Whites: These will bind the ingredients together.
Blueberries: You can use fresh or frozen for this recipe.

Filling

Blueberry Jam: This creates the perfect texture for the filling.
Lemon Zest: This will add some fresh, bright flavor to the blueberries.

Whipped Lemon Frosting

Butter: I used salted butter that was softened to room temperature.
Powdered Sugar: This dissolves easily making the frosting smooth.
Lemon Zest: The more lemon zezt, the better! Having it in all 3 parts of the cake really blends them all together seamlessly!
Vanilla Extract: This adds a sweet flavor.
Heavy Cream: The cream will blend everything together creating the perfect consistency.

How to Make a Lemon Blueberry Cake

This cake takes a few steps but boy is it worth it! Soon you are going to be wanting to make all the lemon blueberry foods that you can get your hands on. It’s the best combo.

Cake

Preheat the oven to 350°. Grease 2 8 inch round cake pans and set aside.
In a small bowl combine the sugar with the zest of the lemons until fragrant.
In a large bowl whisk together the lemon sugar, 2 cups of the flour, baking powder, baking soda, and salt.
To the same bowl add the buttermilk, lemon juice, vanilla, and oil and beat with the paddle attachment of a stand mixer or a hand mixer just until fully combined.
In another bowl whip the egg whites until medium stiff peaks form. Then, fold ⅓ of the egg whites into the cake batter to loosen it up, followed by the remaining egg whites. Fold until only a few streaks of egg whites remain.
Toss the blueberries with the remaining ¼ cup of flour. Fold into the cake batter until just combined.
Separate the cake batter evenly into the two cake pans and bake for about 30-35 minutes, until a toothpick comes out clean and the center of the cake springs back when lightly pressed. Let cool completely before frosting.

Filling

In a small bowl, combine the blueberry jam with the lemon zest. Refrigerate until ready to use.

Whipped Lemon Frosting

Place the soft butter into the bowl of a mixer and use the paddle attachment to beat the butter for about 3 minutes, until it’s a pale-yellow color.
Add the powdered sugar and mix on low until it has been incorporated. Add the lemon zest, vanilla, and 3 tablespoons of cream. Beat on medium-high for about 3 minutes, until light and fluffy. Then, scrape down the sides and bottom of the bowl with a rubber spatula as needed.
For a softer frosting, add more cream 1 tablespoon at a time until the frosting is the desired thickness. For this lemon blueberry cake, I recommend keeping the frosting stiff enough to form thick peaks to frost the cake.

Assembly

Place one cake round top down on the plate or cake stand.
Use a piping bag with a large round or star tip to pipe a dam around the edge of the cake to prevent the filling from coming out the sides. Fill the center of the well with the blueberry jam filling.
Place the second cake round on top of the first, top down. Use the piping bag to pipe frosting all around the outside and top of the cake. Use an offset spatula to smooth the frosting. Top with fresh blueberries and then slices of fresh lemon.

Measuring the Flour

You definitely want to be extra careful in this lemon blueberry cake recipe to measure your flour correctly! Adding too much flour to this cake is a common mistake and can lead to a dry cake. is the most common mistake. Make sure that after you put the flour into your measuring cup that you use a knife to level it off.

How to Store Leftover Lemon Blueberry Cake

If you are lucky enough to have leftovers from this cake then you are in for a treat! This cake lasts for a few days and the leftovers taste delicious! Just store the leftover cake in a covered cake plate at room temperature. You don’t need to refrigerate it. In fact, that dries out the cake and takes away some of the flavor.
