Preparation Phase & Tools to Use

To prepare this cake, you’ll need a few essential tools that ensure your process goes smoothly:

• Stand Mixer or Hand Mixer: Crucial for creaming butter and sugar to create a light and airy texture in the batter.
• 9×13 inch Cake Pan: Provides the right depth and structure for even baking.
• Mixing Bowls: At least two, one for dry and one for wet ingredients.
• Rubber Spatula: Helps fold in ingredients and scrape down bowls to reduce waste.
• Wire Rack: Allows the cake to cool evenly, preventing soggy bottoms.
• Offset Spatula: Ideal for smoothing the frosting to a professional finish.

Each tool plays an important role in achieving a smooth workflow and a cake that bakes and looks just right.

Preparation Tips

Bring your ingredients to room temperature before starting — especially the butter, eggs, and milk. This ensures a smoother batter and even mixing. When making the raspberry swirl, use a spoon or toothpick to gently marble the raspberry purée into the batter without overmixing — you want visible swirls, not a fully pink batter. For the frosting, melt the white chocolate slowly and allow it to cool slightly before mixing it into your buttercream to avoid curdling. Always allow your cake to cool completely before frosting to prevent melting or sliding layers.

Step 1: Prepare the Cake Batter

Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch cake pan with parchment paper. In a medium bowl, whisk together the flour, baking powder, and salt. In a separate large bowl or stand mixer, beat the butter and sugar together until light and fluffy, about 3-4 minutes. Add the egg whites one at a time, mixing well after each addition. Stir in the vanilla extract.

---

Step 2: Combine Wet and Dry Ingredients

In the butter-sugar mixture, add the dry ingredients in three parts, alternating with the milk and sour cream. Start and end with the dry ingredients. Mix just until combined, scraping down the bowl to ensure all ingredients are incorporated. Do not overmix.

Step 3: Add Raspberries and Swirl

Gently fold the raspberries into the batter with a rubber spatula. Pour the batter into the prepared pan and smooth the top. Drop spoonfuls of raspberry jam or preserves over the top, then use a knife or toothpick to gently swirl it into the batter to create a marbled effect.

---

Step 4: Bake the Cake

Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean. The edges should be lightly golden and pulling slightly from the sides of the pan. Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before frosting.

Step 5: Make the White Chocolate Frosting

In a large bowl, beat the softened butter until creamy and smooth. Gradually add the powdered sugar, mixing on low to avoid a sugar cloud. Pour in the cooled melted white chocolate, followed by vanilla extract, salt, and heavy cream. Beat on medium-high for 2-3 minutes until fluffy and spreadable. Add more cream as needed to reach desired consistency.

---

Step 6: Assemble and Decorate

Once the cake has fully cooled, use an offset spatula to generously spread the white chocolate frosting over the top. Swirl the frosting slightly for texture, and garnish with fresh raspberries, white chocolate shavings, and edible flowers if desired. Slice and serve!

Notes

This White Chocolate Raspberry Cake is best served at room temperature, allowing the frosting to soften slightly and the berry flavors to shine through. If you’re using frozen raspberries, toss them in a teaspoon of flour before folding them into the batter — this helps prevent them from sinking to the bottom. For extra white chocolate flavor, consider adding a handful of white chocolate chips into the batter. You can also adjust the raspberry swirl to your taste — less for a milder fruit touch, or more for a tangier punch.

Watch Out for These Mistakes While Cooking

• Overmixing the batter: This can result in a dense, dry cake. Mix until ingredients are just combined.
• Adding hot melted chocolate to the frosting: Doing this can melt the butter and ruin the frosting texture. Always cool it slightly first.
• Not allowing the cake to cool fully before frosting: This can cause the frosting to melt and slide off.
• Skipping the parchment lining: This small step helps prevent sticking and makes transferring the cake easier.
• Swirling too much: If you overdo the raspberry swirl, you’ll lose the marbled effect and muddy the flavors.

Storage Instructions

Store leftover cake covered in the refrigerator for up to 5 days. To preserve freshness, use an airtight container or tightly wrap the cake pan with plastic wrap. Before serving, let the cake sit at room temperature for about 30 minutes to allow the frosting to soften. This cake also freezes well — wrap individual slices in plastic and place them in a freezer-safe container for up to 2 months. Thaw overnight in the fridge and bring to room temp before enjoying.

Frequently Asked Questions

Can I use raspberry puree instead of jam?

Yes! You can cook down fresh or frozen raspberries with a bit of sugar and strain out the seeds to create a smooth puree. Just ensure it’s thickened to avoid adding excess moisture.

Can I make this cake ahead of time?

Absolutely. Bake the cake a day in advance and store it unfrosted, wrapped tightly. Frost just before serving.

Can I use white chocolate chips instead of melting bars?

Yes, but use high-quality chips as some contain stabilizers that affect melting. Chop them finely and melt gently.

What can I use instead of sour cream?

Plain Greek yogurt works well as a substitute, offering a similar texture and tang.

Do I have to use a stand mixer?

No. A hand mixer or even a strong arm with a whisk will do the job, though it may take more time and effort.

Will this recipe work as cupcakes?

Yes! Just adjust the baking time to 18–22 minutes and fill cupcake liners 2/3 full.

Can I double the recipe for a layered cake?

Yes, double the ingredients and bake in two 9-inch round pans. Adjust baking time and check doneness with a toothpick.

Can I make this gluten-free?

Use a 1:1 gluten-free flour blend with xanthan gum for best results. Be sure to check that your white chocolate is also gluten-free.
