When I made this Lemon Blueberry Layer Cake for the first time, I was instantly smitten! The rich, buttery cake layers complement the tartness of the lemon, while the blueberries add a pop of color and flavor. I learned that adding a simple lemon syrup after baking keeps the cake ultra-moist and refreshingly zesty.

In my experience, letting the cake chill for a few hours before serving allows the flavors to meld beautifully. I also recommend opting for organic lemons for the cream and zest—their vibrant flavor will take the cake to a whole new level!

Baking Tips for the Perfect Cake

To achieve the perfect fluffy texture in your layers, be sure to cream the butter and sugar thoroughly until it's light and airy. This process typically takes about 3-5 minutes and is crucial for incorporating air into the batter. When mixing the dry ingredients, use a whisk to combine them instead of a spoon, which helps to aerate the flour mixture and prevent clumping. The goal is to achieve a smooth and homogenous batter before gently folding in the blueberries.

When it's time to bake, evenly distribute your batter among the cake pans. Use a kitchen scale if possible to ensure each cake layer is uniform in size, which will help with stacking later. Keep an eye on your cakes towards the end of the baking time; they’re done when they spring back to the touch and a toothpick comes out clean. If the cakes start to brown too quickly, you can tent them with aluminum foil.

Importance of Ingredients

Using fresh blueberries is key in this recipe; they offer a superior flavor and moisture compared to frozen ones. If you do need to use frozen blueberries, toss them in a bit of flour before folding them into the batter to prevent them from sinking to the bottom during baking. Additionally, the brightness of fresh lemon juice and zest is irreplaceable; it infuses the cake with a vibrant flavor that elevates it, so avoid substitutes if possible.

Opting for buttermilk instead of regular milk adds acidity to the batter, which not only contributes to a tender crumb but also interacts with the baking soda to create a lovely lift. If you don’t have buttermilk on hand, you can make a quick substitute by mixing 1 cup of milk with 1 tablespoon of vinegar or lemon juice, letting it sit for about 5 minutes before use.

Storing and Serving Suggestions

After frosting your cake, you can store it in the refrigerator for up to 5 days. Keep it covered with plastic wrap or in an airtight container to maintain its moisture. If you're planning to make this cake ahead of time, you can freeze the cake layers individually, well-wrapped in plastic, for up to 3 months. Just be sure to thaw the layers in the refrigerator overnight before assembling and frosting.

For serving, this cake is perfect alongside a cup of tea or coffee. You can also elevate the presentation by adding a sprinkle of powdered sugar, a drizzle of lemon glaze, or a dollop of whipped cream on each slice. If you wish to celebrate an occasion, consider garnishing the top with additional blueberries or even lemon slices for a pop of color.

Ingredients

For the Cake

  • 2 ½ cups all-purpose flour
  • 1 ½ cups granulated sugar
  • ½ cup unsalted butter, softened
  • 1 cup buttermilk
  • 4 large eggs
  • 2 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt
  • 2 tbsp lemon zest
  • 1 cup fresh blueberries

For the Lemon Syrup

  • ½ cup granulated sugar
  • ½ cup fresh lemon juice

For the Cream Cheese Frosting

  • 8 oz cream cheese, softened
  • ½ cup unsalted butter, softened
  • 4 cups powdered sugar
  • 2 tbsp fresh lemon juice
  • 1 tsp vanilla extract

Instructions

Prepare the Cake Batter

Preheat your oven to 350°F (175°C). In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, then mix in the buttermilk and lemon zest. In another bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Gently fold in the blueberries.

Bake the Cake

Divide the batter evenly among three greased 8-inch round cake pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. While the cake is baking, prepare the lemon syrup.

Make the Lemon Syrup

In a small saucepan, combine the sugar and lemon juice over medium heat. Stir until the sugar dissolves, then remove from heat and set aside.

Assemble the Cake

Once the cakes are baked, let them cool in the pans for 10 minutes, then transfer to wire racks. While still warm, poke holes in the tops and brush with the lemon syrup. Allow cakes to cool completely.

Prepare the Frosting

In a large bowl, beat the softened cream cheese and butter together until well combined. Gradually add the powdered sugar, lemon juice, and vanilla extract, mixing until smooth and creamy.

Frost and Serve

Place one cake layer on a serving plate and spread a layer of frosting on top. Repeat with the second layer, then top with the final layer of cake. Frost the top and sides of the cake. Garnish with additional blueberries if desired. Chill for at least an hour before serving.

Pro Tips

  • For an extra burst of flavor, consider adding a handful of lemon zest into the frosting. Also, this cake can be made a day in advance
  • it actually tastes better after resting in the fridge overnight.

Troubleshooting Common Issues

If your cake layers dome too much during baking, this may indicate that your oven is running hot. Consider using an oven thermometer to check the accuracy of your temperature settings. To fix this, reduce the temperature by 25°F and extend the baking time slightly, keeping an eye on the cakes as they bake.

In the event that your cake turns out dry, this could be due to overmixing the batter or baking for too long. Ensure that you gently mix the batter until just combined and check for doneness a few minutes before the suggested baking time.

Variations to Try

While this lemon blueberry flavor combination is a winner, you can experiment with other fruits such as raspberries or strawberries for a different twist. Adjust the lemon flavor by adding more zest or combining it with other citrus fruits, such as orange or lime, to create a citrus medley cake.

For a richer flavor, consider adding a layer of lemon curd between the cake layers along with the frosting for an extra burst of lemony goodness. Alternatively, folding in some coconut flakes could add a delightful texture and flavor to the cake.
