Preparation Steps

Step 1: Prepare the Baking Pans

Preheat your oven to 350°F (175°C). Grease and flour two round cake pans or line them with parchment paper for easier removal.

This helps the cake layers bake evenly and prevents sticking.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.

Set the mixture aside while preparing the wet ingredients.

Step 3: Cream Butter and Sugar

In a large mixing bowl, beat the softened butter and granulated sugar together until light, fluffy, and creamy.

This process adds air into the batter, helping create a soft and tender cake texture.

Step 4: Add Eggs and Flavoring

Add the eggs one at a time, mixing well after each addition.

Stir in the vanilla extract, lemon zest, and fresh lemon juice. The batter will become fragrant with a bright citrus aroma.

Step 5: Combine Wet and Dry Ingredients

Gradually add the dry ingredients into the butter mixture, alternating with the buttermilk.

Mix gently until fully combined and smooth.

Carefully fold in the fresh blueberries using a spatula to avoid crushing them.

Step 6: Bake the Cake

Divide the batter evenly between the prepared pans.

Bake for approximately 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.

Allow the cakes to cool completely before frosting.

Preparing the Blueberry Filling

Step 7: Cook the Filling

In a small saucepan, combine blueberries, sugar, lemon juice, and cornstarch.

Cook over medium heat while stirring gently until the blueberries soften and the mixture thickens slightly.

Allow the filling to cool completely before using.

This filling creates a rich fruity layer that pairs beautifully with the lemon cake.

Preparing the Lemon Frosting

Step 8: Make the Frosting

In a large bowl, beat the butter and cream cheese until smooth and creamy.

Gradually add the powdered sugar while mixing on low speed.

Add the lemonade concentrate and vanilla extract, then continue beating until fluffy and silky.

The frosting should have a light citrus flavor with a creamy texture.

Assembling the Cake

Step 9: Layer the Cake

Place the first cake layer onto a serving plate.

Spread a layer of lemon frosting over the cake, followed by a spoonful of blueberry filling.

Place the second cake layer on top and frost the entire cake smoothly.

Allow some frosting to drip naturally down the sides for a beautiful bakery-style appearance.

Step 10: Decorate the Cake

Top the cake with fresh blueberries, lemon slices, mint leaves, and a little lemon zest for an elegant finish.

The colorful garnish gives the cake a fresh and vibrant presentation perfect for any special occasion.
