For the Cake

2 ½ cups (315g) all-purpose flour
2 teaspoons baking powder
½ teaspoon baking soda

½ teaspoon salt
1 cup (226g) unsalted butter, softened
1 ¾ cups (350g) granulated sugar

4 large eggs (room temperature)
Zest of 2 lemons
¼ cup fresh lemon juice

1 teaspoon vanilla extract
1 cup (240ml) buttermilk
1 ½ cups fresh blackberries (lightly floured)

For the Lemon Cream Cheese Frosting

8 oz (225g) cream cheese, softened
½ cup (113g) unsalted butter, softened
3–4 cups powdered sugar

2 tablespoons lemon juice
1 teaspoon lemon zest
1 teaspoon vanilla extract

Step-by-Step Instructions

Step 1: Prepare Your Pans

Preheat oven to 350°F (175°C).

Grease and line two 9-inch round cake pans with parchment paper.

Step 2: Mix Dry Ingredients

In a bowl, whisk together:

Flour
Baking powder
Baking soda

Salt

Set aside.

Step 3: Cream Butter and Sugar

In a large mixing bowl:

Beat butter and sugar until light and fluffy (about 3–4 minutes).
Add eggs one at a time, mixing well after each addition.
Mix in lemon zest, lemon juice, and vanilla extract.

Creaming properly creates a light texture.

Step 4: Combine Wet and Dry Ingredients

Add dry ingredients in three additions, alternating with buttermilk:

Dry → Buttermilk → Dry → Buttermilk → Dry

Mix until just combined.

Step 5: Fold in Blackberries

Toss blackberries lightly in flour (prevents sinking).

Gently fold into batter using a spatula.

Step 6: Bake

Divide batter evenly between pans.

Bake for 30–35 minutes, or until:

A toothpick inserted in the center comes out clean.

The top springs back lightly when touched.

Let cakes cool completely before frosting.

How to Make Lemon Cream Cheese Frosting

Beat cream cheese and butter until smooth and creamy.

Gradually add powdered sugar.
Mix in lemon juice, zest, and vanilla.
Beat until fluffy.

If frosting is too thick, add 1 tablespoon milk.
If too thin, add more powdered sugar.

Assembling the Cake

Place one cake layer on a serving plate.
Spread an even layer of frosting on top.

Add the second cake layer.
Frost the top and sides.
Garnish with fresh blackberries and lemon zest.

For extra elegance, drizzle with a light lemon glaze.
