Chantilly Cream Frosting
2 1/2cupsHeavy Cream, (cold)
3 1/2cupsPowdered Sugar
1tbspVanilla Bean Paste
1/4tspAlmond Extract
16ozMascarpone, (cold)
8ozCream Cheese, (room temperature
Instructions
Preheat oven to 350°F. Spray 4 8-inch round cake pans with nonstick baking spray or line with parchment paper. (you can use 3 pans for thicker cake layers)
In a large mixing bowl, whisk together cake flour, baking powder, baking soda, nutmeg, and kosher salt.
In the bowl of a stand mixer fitted with the paddle attachment, beat butter and granulated sugar on medium speed until fluffy, about 3 minutes, scraping down sides of bowl. Add eggs, one at a time, ensuring each egg is fully incorporated prior to adding the next. Add vanilla bean paste (or extract), almond extract, sour cream, and continue to beat until well combined.
Add half of the dry ingredients to the bowl, then pour in the heavy cream and mix until just combined, about 15 seconds. Scrape down the sides of the bowl and add the remainder of the flour mixture. Continue to mix until just combined and smooth, about 15 seconds.
Divide the cake batter among the prepared pans. Bake until a wooden pick inserted in center comes out clean, 28 to 30 minutes. Let cool in pans for 10 minutes. Remove from pans, and let cool completely on a wire rack.
Cut the berries in half (cut the strawberries into quarters) and place into a large bowl. Set aside.
Now make the mascarpone chantilly cream. Add heavy cream, vanilla bean paste, almond extract, and powdered sugar to the bowl of a stand mixer fitted with the whisk attachment. Mix on low speed for about 1 minute, gradually increasing to medium-high speed. Mix for 2-3 minutes, until the cream begins to thicken (soft peaks), then add mascarpone and cream cheese. Continue to mix until stiff peaks are reached, about 1-2 minutes, until smooth and creamy.
Place the first cake layer on a cake stand. Brush with the raspberry jam (if it's too thick, microwave for 10 seconds to loosen it up a bit), then spread an even layer of frosting onto the cake. Sprinkle with 1/3 of the berries. Top with the next cake layer and repeat until all layers are added. Spread a thin layer of frosting on top and sides of the cake. Place into the refrigerator to set for 30 minutes. Remove from the refrigerator and use an offset spatula to add the remainder of the frosting. Garnish with berries on top.
Notes
Room temperature ingredients are a must. Cold eggs or butter can break with the batter and lead to uneven mixing. You'll want to use room temperature eggs, butter, heavy cream, and sour cream for the cake.
Whip the mascarpone cream just until smooth. Over-mixing can cause it to break or turn grainy.
Chill the cake before frosting. A cold cake is easier to frost, especially with a soft whipped cream based frosting.
Assemble with care. Add a thin layer of frosting between each cake layer to keep the berries in place and prevent sliding.
Assemble and Decorate right before serving - Berries can release juices over time, so keep it looking fresh by adding fruit at the end.
