Instructions
- Prep the Pans:
- Preheat the oven to 350°F (175°C).
- Lightly grease three 8-inch round cake pans and line the bottoms with parchment paper. Set aside.
- Tip: Trace and cut parchment circles for a perfect fit.
- Mix Dry Ingredients:
- In the bowl of a stand mixer fitted with the paddle attachment, combine 2 cups granulated sugar, 2 3/4 cups cake flour (spooned and leveled), 2 1/2 tsp baking powder, and 1/2 tsp salt.
- Mix on low speed until combined.
- Tip: Spoon flour into the measuring cup and level with a knife to avoid packing.
- Add Butter:
- Add 3/4 cup unsalted butter (room temperature) and increase to medium speed.
- Beat for 3 minutes until the mixture resembles damp sand.
- Tip: Scrape the bowl to ensure even mixing.
- Incorporate Wet Ingredients:
- On low speed, gradually add 1 cup heavy cream, 1/2 cup buttermilk, and 2 tsp vanilla extract.
- Increase to medium speed and beat for 2 minutes until thick and smooth.
- Scrape down the sides and bottom of the bowl, then mix for 30 seconds more.
- Tip: Add liquids slowly to prevent splashing.
- Add Egg Whites:
- On low speed, add 1 cup egg whites in thirds, beating for 20 seconds after each addition.
- The batter should be silky smooth; avoid overmixing.
- Tip: Ensure egg whites are at room temperature for better incorporation.
- Bake:
- Divide the batter evenly among the three prepared pans (use a scale for precision).
- Bake for 20-22 minutes, until pale golden, slightly shrinking from pan edges, and springy to the touch. A toothpick inserted in the center should come out clean.
- Cool in pans for 10 minutes, then invert onto a wire rack to cool completely.
- Tip: Level cakes with a serrated knife if they dome for easier stacking.
White Chocolate Buttercream
- Melt White Chocolate:
- In a large heatproof, microwave-safe bowl, melt 12 oz finely chopped white chocolate in 30-second increments at 50% power, stirring well each time until smooth.
- Let cool to room temperature.
- Tip: Stir frequently to prevent burning; avoid overheating.
- Beat Butter:
- In a stand mixer with the paddle attachment, beat 2 cups softened unsalted butter on medium speed until creamy (2-3 minutes).
- Tip: Ensure butter is soft but not melted for a fluffy frosting.
- Add Sugar:
- On low speed, gradually add 4 cups powdered sugar. Once incorporated, increase to high speed and beat for 2 minutes.
- Scrape down the bowl.
- Tip: Sift powdered sugar if clumpy for a smoother result.
- Finish Buttercream:
- Add cooled melted white chocolate and beat on medium speed for 2 minutes.
- Add 1/4 cup heavy cream (or whole milk) and beat for 1 minute until light and fluffy.
- Transfer one-third of the buttercream to a piping bag and snip the end.
- Tip: If frosting is too soft, chill for 10 minutes before piping.
Cake Assembly
- Layer the Cake:
- Place one cooled cake layer on a serving plate or cake stand.
- Pipe a ring of buttercream around the edge, fill the center with 1/4 cup raspberry preserves, then pipe a thin layer of buttercream over the preserves.
- Add the second cake layer and press gently to adhere.
- Repeat with another buttercream ring, 1/4 cup raspberry preserves, and a buttercream layer.
- Place the final cake layer on top.
- Tip: Pipe the buttercream ring to create a “dam” to hold the preserves in place.
- Crumb Coat:
- Spread a thin layer of buttercream over the top and sides of the cake using an offset spatula.
- Chill the cake in the refrigerator for 30 minutes to set the crumb coat.
- Tip: A crumb coat locks in crumbs for a smooth final layer.
- Final Frosting:
- Spread the remaining buttercream in a thick, even layer over the top and sides.
- Use a cake scraper or bench scraper to smooth the frosting.
- Tip: Dip the scraper in warm water for a super-smooth finish.
- Garnish and Serve:
- Decorate the top edge with 1 cup fresh raspberries and scatter white chocolate curls over the top.
- Slice into 8-12 wedges and serve at room temperature or slightly chilled.
- Health Benefit: Raspberries provide vitamin C and antioxidants, but this rich cake is a decadent treat to savor!
