How to Make White Chocolate Raspberry Cake

White Chocolate Cake

1. Prepare equipment. Preheat oven to 350°F. Line three 8-inch cake pans with parchment paper circles and spray with baking spray.
2. Melt chocolate. Melt white chocolate into the milk. Combine fully and let it cool for 15-20 minutes.

3. Add wet ingredients. While the chocolate mixture is cooling, cream the butter and sugar in the large bowl of a stand mixer with the paddle attachment, or a large mixing bowl if using an electric mixer. Add the eggs and vanilla extract, mixing to combine.
4. Add sour cream. Next, add the sour cream, and mix until fully combined.

5. Add dry ingredients. Mix the flour, baking powder, and salt into the mixture to form the batter.
6. Add the chocolate and bake. Now add the cooled white chocolate and milk mixture and mix to combine. Divide the batter between the prepared pans and bake in the preheated oven for 24-28 minutes. Level off the tops of the cakes, if needed.

Raspberry Filling

1. Cook the berries. Add the raspberries and sugar to a medium saucepan and cook over medium heat, stirring frequently, until the raspberries release their juices and break down. This should take about 8-10 minutes.
2. Thicken the mixture. In a small, separate bowl, whisk together the cornstarch, lemon juice, and water to create a slurry. Add to the raspberry mixture while stirring and continue to cook another 1-2 minutes until thickened and goes from cloudy to clear. The filling will continue to thicken as it cools, so it shouldn’t be too thick and paste-like in the pan.
3. Let it cool. Remove from heat and cool completely before using to fill a cake.

White Chocolate Frosting

1. Melt chocolate. Place the chocolate pieces in a medium bowl and melt fully.
2. Let it cool. Allow the chocolate to cool for 15-20 minutes until no longer warm to the touch so that it doesn’t melt the butter.

3. Combine butter and chocolate. Beat the butter using the whisk attachment of your hand or stand mixer, and then mix in the melted and cooled white chocolate.
4. Add remaining ingredients. Next, add the powdered sugar, vanilla extract, and heavy cream to the butter mixture.

5. Mix. Lastly, mix the ingredients together until just combined.

Assembling and Decorating

1. Frost the edge. Place the bottom cake layer on a cake plate and pipe white chocolate buttercream frosting around the edge of the cake’s top surface.
2. Add Raspberry filling. Fill the inside of the frosting circle with the raspberry filling.

3. Cover with frosting. Pipe enough frosting onto the top of the filling to cover the cake layer.
4. Spread. Completely cover the cake layer by spreading the frosting evenly over it using an offset spatula or a butter knife.

5. Add the next layers. Carefully place the second cake layer on top and repeat the steps above, and then finish by placing the third cake layer on top.
6. Frost the cake. Cover the outside of the cake completely with a thin layer of buttercream frosting.

7. Add raspberries. Create a crown of raspberries around the edge of the cake’s top surface by gently pressing raspberries into the frosting so that they are all pointing upwards.
8. Slice and serve. Portion and slice the cake, transferring each slice onto a serving plate.

Recipe FAQ’s

Tips for Success

• Read through the entire recipe before starting to prepare all your ingredients, and make sure your oven is correctly calibrated for accurate baking temperatures.
• Ensure your ingredients like eggs, butter, and sour cream are at room temperature for a smoother batter and even baking.
• Overmixing the batter can lead to a dense cake, so mix just until the ingredients are combined.
• You can use a kitchen scale to divide the batter evenly between the pans for uniform cake layers.
• Use a toothpick to check the doneness of your cake layers. It should come out clean or with a few moist crumbs.
• The filling should be thick enough to stay between the layers but not so thick that it becomes difficult to spread.
• Ensure the melted white chocolate is cooled but still fluid before adding it to the frosting.
• If you’re not confident with piping you can practice your piping skills on a piece of parchment paper before applying the frosting to the cake.
• For a cleaner look to the cake, apply a thin layer of frosting first to catch any crumbs, then chill the cake before adding the final layer of frosting.

Substitutions and Variations

• If you can’t get enough of that white chocolate flavor, you can sprinkle white chocolate curls on top of the cake, or even add a thin layer of white chocolate ganache.
• You can garnish the cake with fresh raspberries like I have, or try something else such as lemon zest and white chocolate shavings for added elegance.
• Use unsalted butter if you need to, and adjust the salt in the recipe accordingly.
• Greek yogurt is a great substitute for sour cream and will add a similar tanginess.
• Instead of raspberries, try using strawberries or mixed berries for a different flavor.
• If you want a lighter frosting, check out my recipes for whipped cream frosting and Swiss meringue buttercream!
• Consider adding some white chocolate curls, chopped nuts, sprinkles, or edible flowers to the top for decoration.
