For the Cake Layers

• 2 ¾ cups all-purpose flour
• 2 ½ teaspoons baking powder
• ½ teaspoon salt
• 1 cup unsalted butter, softened
• 1 ¾ cups granulated sugar
• 4 large eggs
• 2 teaspoons vanilla extract
• 1 cup whole milk
• ½ cup sour cream
• 6 ounces white chocolate, melted and cooled

For the Raspberry Filling

• 2 cups fresh raspberries
• ⅓ cup granulated sugar
• 1 tablespoon lemon juice
• 1 tablespoon cornstarch
• 2 tablespoons water

For the White Chocolate Buttercream

• 1 cup unsalted butter, softened
• 4 cups powdered sugar
• 5 ounces white chocolate, melted and cooled
• 3 tablespoons heavy cream
• 1 teaspoon vanilla extract

For Decoration

• Fresh raspberries
• White chocolate curls or shavings

Directions

Preheat the oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment paper.

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

In a large mixing bowl, beat the butter and sugar until light and fluffy, about 3 to 4 minutes. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and melted white chocolate.

Mix in the sour cream. Gradually add the dry ingredients alternately with the milk, beginning and ending with the flour mixture. Mix until just combined.

Divide the batter evenly among the prepared cake pans. Bake for 22 to 26 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool completely before assembling.

To make the raspberry filling, combine raspberries, sugar, and lemon juice in a saucepan over medium heat. Cook until the berries begin to break down. In a small bowl, mix cornstarch and water, then stir it into the raspberry mixture. Cook for another 2 minutes until thickened. Cool completely.

For the buttercream, beat the butter until creamy. Gradually add powdered sugar, then mix in the melted white chocolate, vanilla extract, and heavy cream. Beat until smooth and fluffy.

Place one cake layer on a serving plate. Spread a layer of buttercream around the edge to create a border, then spoon raspberry filling into the center. Repeat with the second layer.

Add the final cake layer and frost the top and sides with the remaining buttercream. Decorate with fresh raspberries and white chocolate curls.

Chill the cake for at least 30 minutes before slicing for cleaner layers.

Variations

• Add almond extract instead of vanilla for a bakery-style flavor.
• Use raspberry jam if fresh raspberries are unavailable.
• Turn the recipe into cupcakes by reducing the baking time to about 18 minutes.
• Add lemon zest to the batter for a brighter flavor.
• Use strawberries or blackberries instead of raspberries for a different fruit variation.
• Make it extra rich by adding white chocolate ganache between the layers.

Storage/Reheating

Store the cake covered in the refrigerator for up to 4 days. Because of the raspberry filling and buttercream, refrigeration helps keep the cake fresh and stable.

Before serving, let the cake sit at room temperature for about 20 minutes so the frosting becomes soft and creamy again.

Individual slices can also be frozen for up to 2 months. Wrap each slice tightly in plastic wrap and place in a freezer-safe container. Thaw overnight in the refrigerator before serving.
