Step-by-Step Instructions
Preparing the Cake Layers
Begin by preheating your oven to 350°F (175°C). Proper oven temperature is crucial for even baking and optimal cake texture. Lightly grease two 8-inch round cake pans with butter or non-stick spray, then dust with flour to prevent sticking. Using parchment paper to line the bottoms of the pans enhances release and maintains clean edges. Set aside.
In a large mixing bowl, sift together the cake flour, sugar, baking powder, and salt. Sifting ensures that dry ingredients are evenly distributed, preventing clumping which can cause uneven rising. Add the shortening, milk, and vanilla extract to the dry mixture. Using an electric mixer set to low speed, blend these ingredients for about 30 seconds. Scrape down the sides of the bowl with a silicone spatula to incorporate any unmixed ingredients.
Increase the mixer speed to high and beat for 2 minutes. This process aerates the batter, giving the cake a light, tender crumb. The mixture should be smooth, shiny, and slightly fluffy. In a separate clean bowl, beat the egg whites until stiff peaks form, then gently fold into the batter. This step contributes to the cake’s rise and airy texture.
Finally, fold in the melted white chocolate carefully to maintain the batter’s lightness. The batter will be thick but spreadable. Divide it evenly between the prepared pans using a spatula, smoothing the tops for even baking.
Bake for 30 to 35 minutes, or until a wooden pick inserted into the center comes out clean. Do not open the oven door frequently during baking as this can cause the cake to sink. Once baked, transfer the pans to wire racks to cool completely. Cooling thoroughly prevents melting or collapsing when assembling.
Once cooled, slice each cake horizontally with a serrated knife or cake leveler to create four layers. Use a gentle sawing motion for clean, even layers. Wrap each layer in plastic wrap and refrigerate until ready to assemble.
Making the Strawberry White Chocolate Mousse (Best prepared the night before)
Start by melting 1 1/2 cups of white chocolate. Use a double boiler by placing a heatproof bowl over a saucepan filled with a couple of inches of simmering water. Stir continuously until smooth and completely melted. Remove from heat and set aside to cool slightly.
While the chocolate cools, prepare the strawberries. Wash and hull the strawberries, then puree them in a blender or food processor until smooth. For an extra silky texture, you can pass the puree through a fine mesh strainer to remove seeds, though this step is optional.
In a small saucepan, combine the strawberry puree with a few tablespoons of strawberry preserves or jam for added sweetness and depth of flavor. Cook over medium heat, stirring constantly, until the mixture thickens slightly and begins to boil. Remove from heat and allow to cool just enough to avoid melting the chocolate when combined.
Gradually fold the warm strawberry mixture into the cooled white chocolate until fully combined. Allow this mixture to cool to tepid temperature. Once cooled, gently fold in the whipped cream, which should be whipped to soft peaks, folding carefully to preserve airiness. Then, fold in the whipped egg whites until smooth and homogeneous.
Transfer the mousse to a bowl, cover with plastic wrap, and refrigerate at least 8 hours or overnight. This long chilling time allows the mousse to firm up, making it easier to spread between cake layers and ensuring a stable texture upon serving.
Preparing the White Chocolate Icing
This icing is the final touch that provides a glossy, smooth surface and a rich flavor profile. Melt 3 ounces of white chocolate using the double boiler method. In a separate medium saucepan, combine the melted chocolate with flour and gradually stir in milk. Cook over medium heat, stirring constantly, until the mixture thickens to a consistency similar to melted chocolate. Remove from heat and cool completely.
Meanwhile, beat together the softened butter, sugar, and vanilla extract until light and fluffy. This process incorporates air, making the icing smooth and spreadable. Once the chocolate mixture cools, gradually blend it into the creamed butter mixture. Do not overmix; stop once the ingredients are just combined to prevent the icing from becoming runny. Chill the icing slightly if it becomes too soft to spread easily.
Assembling the Cake
Begin by placing one cake layer on your serving platter. Spread a generous amount of the prepared strawberry mousse evenly over the surface, ensuring it reaches the edges. Carefully place the second cake layer on top and repeat with mousse. Continue with the third and fourth layers, creating three mousse layers in total. Be cautious to avoid overfilling, which can cause leakage during icing.
Once assembled, place the cake in the freezer for about 30 minutes. This step helps set the mousse and stabilize the structure. While the cake chills, melt the remaining 3 ounces of white chocolate. Arrange thinly sliced strawberries on a sheet covered with plastic wrap. Drizzle the melted white chocolate in thin ribbons over the strawberries for decorative appeal. Once set, they can be used to adorn the cake’s top.
Remove the cake from the freezer. Using an offset spatula, generously spread the white chocolate icing over the entire cake, creating soft peaks and smooth surfaces. Decorate the top with the chocolate-drizzled strawberries arranged in a circular pattern, and optionally, place five strawberries in the center to form a flower.
Allow the decorated cake to sit at room temperature briefly before slicing. This helps the icing set and reduces cracking. Serve slices with a dollop of whipped cream or extra strawberries for an elegant presentation.
Preparation Tips
- Ingredient Quality: Use high-quality white chocolate for a rich, smooth flavor. Avoid chocolate chips with stabilizers, opting for baking or couverture white chocolate.
- Strawberry Selection: Choose ripe, fragrant strawberries for maximum flavor. Fresh, fragrant berries make a significant difference in the mousse’s brightness and overall impact.
- Temperature Control: When melting chocolate, keep the heat gentle to prevent scorching. Use a thermometer if necessary to monitor temperature, ideally around 110°F (43°C) for melting.
- Layer Uniformity: When slicing cake layers, use a serrated knife and a gentle sawing motion to achieve even, level layers. This ensures the final appearance is polished and the layers stack evenly.
- Chilling and Setting: Patience is key. Proper chilling allows mousse to set fully, which is crucial for clean slicing and a stable structure.
- Decorative Precision: When decorating with strawberries and chocolate, work quickly before the chocolate sets. Use chilled tools for clean lines and precise placement.

FAQ
Can I prepare this cake ahead of time?
Yes, the mousse can be prepared a day in advance and stored in the refrigerator. Assemble the cake shortly before serving to ensure optimal texture and appearance.
Can I substitute fresh strawberries with frozen?
Fresh strawberries provide the best flavor and texture, but frozen strawberries can be used if thawed completely and drained well to avoid excess moisture, which can affect the mousse’s consistency.
Is white chocolate suitable for those with nut allergies?
White chocolate can sometimes contain traces of nuts depending on the brand. Always check labels and opt for nut-free varieties if necessary.
How do I prevent the mousse from leaking during assembly?
Ensure that each layer is set firmly before adding the next. Chilling the assembled cake in the freezer for 30 minutes helps stabilize the mousse. Use a sharp knife to level layers evenly.
