Indulge in Perfection: The Ultimate Six-Inch White Chocolate Layer Cake with Silky Buttercream and Raspberry Filling
There’s a special kind of magic that happens when you combine the delicate sweetness of white chocolate with a perfectly baked cake. This particular recipe for a Six-Inch White Chocolate Cake isn’t just another dessert; it’s a testament to a journey of discovery. A few months ago, a friend inquired about a white chocolate cake recipe, and to my dismay, I had no stellar option to share. That moment sparked a delightful obsession. Since then, I’ve been on a quest, meticulously trying various white chocolate cake recipes, determined to find and perfect the ultimate version.
My culinary adventures led me down several paths. First, there was the charming and delicious White Chocolate Bundt Cake, a wonderful introduction to the world of white chocolate baking. Next came a recipe I won’t even mention, as it was, frankly, a complete disaster – a learning experience, if nothing else! But every baker knows that persistence pays off, and this latest creation is the triumphant result of that dedication. It’s a remarkably straightforward white chocolate cake, elevated by a luscious buttercream frosting and a vibrant layer of raspberry preserves, offering a symphony of flavors and textures in every bite.

A New Favorite: Why This Six-Inch White Chocolate Cake Shines
Having baked this cake multiple times now, I can confidently say it has earned its place as one of my absolute favorite small layer cakes. Originally inspired by a recipe from the esteemed Food & Wine, I’ve adapted and refined it to create a truly exceptional experience. The flavor profile is impeccably balanced – not overly sweet, allowing the nuanced notes of white chocolate to truly sing. The texture is divine: light, airy, and remarkably non-greasy, which can sometimes be a pitfall with white chocolate recipes. It bakes up beautifully with consistently even layers, making it a joy to assemble and present.
But what truly elevates this cake to a new level is the accompanying white chocolate buttercream. And here’s the secret: it’s even better than the cake itself! Unlike many buttercreams that are excessively sweet, this recipe uses only ½ cup of confectioners’ sugar. This conscious decision allows the rich, creamy essence of the white chocolate and butter to dominate, resulting in a frosting that is genuinely decadent without being cloying. It whips up incredibly smooth and creamy, making it a dream to spread and ensuring a luxurious mouthfeel with every forkful.
The beauty of a six-inch cake lies in its versatility and charm. It’s the perfect size for smaller gatherings, intimate celebrations, or simply when you crave a homemade treat without committing to a full-sized, often overwhelming, nine-inch cake. It bakes faster, cools quicker, and is generally more manageable to decorate, making it an ideal project for both novice and experienced bakers alike. This recipe specifically caters to that desire for a delightful, manageable, yet utterly impressive dessert.

Scaling Up: Adapting to a 9-Inch Round White Chocolate Cake
While this recipe is meticulously crafted for two six-inch round cake pans, it’s entirely possible to scale it up if you’re planning for a larger crowd or prefer a more substantial cake. To make the full version suitable for two nine-inch round pans, you’ll simply need to double the entire recipe. Alternatively, you can refer to the original Food & Wine recipe which likely provides quantities for standard larger cake pans.
When scaling a recipe, a few considerations are key. Doubling ingredients is usually straightforward, but remember that baking times will almost certainly increase for larger, thicker cakes. Always keep a close eye on your oven and test for doneness with a skewer or toothpick inserted into the center. Additionally, ensure your mixing bowl is large enough to comfortably handle the increased volume of batter. You might also find that a larger cake requires slightly more frosting, so consider making an extra half batch of buttercream to ensure ample coverage and a generous filling.
Regardless of the size, the core principles of this white chocolate cake remain the same: quality ingredients, precise measurements, and careful execution. The delicious flavor and tender crumb will shine through whether you’re baking a petite six-inch marvel or an impressive nine-inch centerpiece.

Tips for Baking the Perfect White Chocolate Cake
Achieving a bakery-quality white chocolate cake at home is entirely within reach with a few essential tips:
- Ingredient Temperature: Ensure your butter and eggs are at room temperature. This allows them to cream together more effectively, creating a smooth emulsion that traps air for a lighter, fluffier cake.
- Quality White Chocolate: The type of white chocolate you use truly matters. Opt for a good quality bar or baking discs with a high cocoa butter content (at least 20%). Avoid white chocolate chips or candy melts if possible, as they often contain stabilizers that can affect the texture and flavor of the cake.
- Do Not Overmix: Once you add the flour mixture, mix just until combined. Overmixing develops the gluten in the flour, leading to a tough, dense cake.
- Proper Pan Preparation: Greasing and flouring your pans meticulously prevents sticking. For extra security, you can line the bottoms with parchment paper cut to size.
- Don’t Open the Oven Door Too Early: Resist the urge to check on your cakes too frequently, especially in the first two-thirds of the baking time. Fluctuations in temperature can cause cakes to sink.
- Cooling Process: Allow cakes to cool in their pans for 10-15 minutes before inverting them onto a wire rack to cool completely. Cooling completely before frosting is crucial to prevent the buttercream from melting.
The Art of White Chocolate Buttercream
This buttercream recipe is a highlight, and mastering it will elevate any cake. The key to its smoothness and rich flavor is the balance of ingredients and careful mixing. Make sure your butter is truly softened (but not melted) to achieve a creamy base. When melting the white chocolate, do it gently and allow it to cool slightly before incorporating it into the butter. Adding warm chocolate will melt the butter and ruin the frosting’s consistency. Beat until the frosting is light and fluffy, scraping down the sides of the bowl often to ensure everything is fully combined. This meticulous approach guarantees a silky, delectable frosting that complements the cake beautifully.
Serving Suggestions and Variations
While the raspberry preserves provide a delightful tart contrast to the sweet white chocolate, feel free to experiment with other fillings. A thin layer of lemon curd would offer a bright, zesty note. For a richer flavor, a dark chocolate ganache could create a striking “cookies and cream” effect. Fresh berries (strawberries, blueberries, or mixed berries) also make excellent additions, especially when lightly sweetened. This cake pairs wonderfully with a cup of coffee, tea, or even a glass of sparkling wine, making it a versatile dessert for any occasion.
Storing Your White Chocolate Cake
To keep your white chocolate cake fresh and delicious, store it in an airtight container at room temperature for up to 2-3 days. If you need to store it longer, it can be refrigerated for up to a week. Be sure to bring it back to room temperature for about 30 minutes before serving to ensure the cake and frosting are at their optimal texture and flavor. For longer storage, slices can be individually wrapped and frozen for up to a month, then thawed overnight in the refrigerator.

Pin Recipe
Ingredients
- 4 oz white chocolate chopped (114 grams), good quality for best flavor and texture
- 1 cup plus 2 T. all-purpose flour 140 grams, spooned and leveled
- 1 ⅛ tsp. baking powder for ideal rise and tender crumb
- ¼ scant tsp. salt to balance the sweetness
- 6 tablespoons unsalted butter softened to room temperature
- ¾ cup granulated sugar 150 grams
- 2 large eggs at room temperature
- ¾ tsp. vanilla extract pure vanilla for best flavor
- ½ cup plus 2 T. whole milk (5 oz), at room temperature for smooth batter
White Chocolate Buttercream frosting
- 1 stick 114 grams unsalted butter, softened to room temperature
- 6 ounces white chocolate melted and cooled slightly (use good quality for superior taste)
- ½ cup confectioners’ sugar sifted, for a smooth frosting
- ½ teaspoon pure vanilla extract enhances overall flavor
Instructions
-
Preheat your oven to 350 degrees F (175 C). Thoroughly grease and flour two 6-inch round cake pans, ensuring every surface is coated to prevent sticking. You may also line the bottoms with parchment paper for easy removal.
-
Carefully melt the chopped white chocolate in a microwave-safe bowl. Use your preferred method – a double boiler works well, or microwave at 50% power, stirring frequently (every 60 seconds initially, then every 30 seconds as it melts) until smooth. It’s crucial not to overheat the white chocolate, as it can seize. Once melted, allow it to cool slightly to lukewarm temperature.
-
In a separate medium bowl, whisk or stir together the all-purpose flour, baking powder, and a scant ¼ teaspoon of salt. This ensures these dry ingredients are evenly distributed throughout the batter.
-
In a large mixing bowl, using an electric mixer (stand or hand-held), beat the softened unsalted butter and granulated sugar together on medium speed until the mixture is light, fluffy, and pale in color. This creaming process can take 3-5 minutes. Remember to scrape down the sides and bottom of the bowl frequently to ensure even mixing. Add the eggs one at a time, beating well after each addition until fully incorporated before adding the next. Beat in the vanilla extract, then gently stir in the slightly cooled melted white chocolate until just combined.
-
With the mixer on low speed, add the flour mixture and the milk alternately to the butter mixture, beginning and ending with the flour. Start by adding about one-third of the flour mixture, mix until just combined, then add half of the milk, mix. Repeat with another third of the flour, the remaining milk, and finally the last third of the flour. Stir only until the ingredients are just blended and no dry streaks of flour remain. Be careful not to overmix the batter.
-
Divide the cake batter evenly between the two prepared 6-inch pans. Use an offset spatula to gently spread the batter to the edges and level the tops. Bake for approximately 25 minutes, or until a wooden skewer or toothpick inserted into the center of the cakes comes out clean or with only moist crumbs attached. The edges should be lightly golden.
-
Once baked, let the cakes cool in their pans on a wire rack for about 10-15 minutes before carefully inverting them onto the wire rack to cool completely. The cakes must be completely cool before frosting to prevent the buttercream from melting.
-
To make the White Chocolate Buttercream frosting: In a clean mixing bowl, beat the softened butter with an electric mixer on medium-high speed until it becomes creamy and pale, about 2-3 minutes. Gradually beat in the slightly cooled melted white chocolate until fully combined. Add the sifted confectioners’ sugar and pure vanilla extract. Start beating at low speed to avoid a cloud of sugar, then gradually increase to medium-high speed. Continue beating, scraping the sides and bottom of the bowl often, until the frosting is light, fluffy, and wonderfully smooth. This can take another 3-5 minutes.
-
Once the cakes are fully cooled, level the tops with a serrated knife if necessary. Place one cake layer on your serving plate or cake stand. Spread about a third of the white chocolate buttercream evenly over the top. If desired, spread a thin layer of raspberry preserves over the buttercream. Place the second cake layer on top. Use the remaining buttercream to frost the top and sides of the cake. Decorate as desired, and serve!
