Ingredients

White Cake

  • 1 box white Cake Mix (I used Duncan Hines)
  • 1 cup whole milk
  • ½ cup vegetable oil or melted butter
  • 3 eggs you can also use only whites

Berry Jam Filling

  • ½ cup strawberry jam
  • ½ cup seedless raspberry jam

Chantilly Whipped Cream Icing

  • 8 ounces cream cheese full fat
  • 8 ounces mascarpone cheese
  • 2 cups heavy whipping cream
  • 2 cups powdered sugar
  • 1 tsp vanilla extract
  • 1 tsp almond extract
  • Fresh Fruit to garnish - I use strawberries raspberries, blueberries and blackberries

Instructions

Vanilla Sponge Cake

  • Preheat oven to 350°. Prepare Jelly Roll pan or 9 X 13 baking dish by spraying with baking spray.
  • Place cake mix in a large mixing bowl. Add in eggs, milk, and vegetable, canola oil or melted butter. Beat with an electric mixer or in a stand mixer until batter is smooth, about 2 minutes, scraping down sides as needed.
  • Spread batter into the pan evenly and bake for about 30 to 40 minutes for a 9 X 13 dish or 10 to 15 minutes for a jelly roll pan. It will be done when a toothpick inserted into the center comes out clean.
  • Remove from oven and let slightly cool while preparing jam filling.

Jam Filling

  • In a microwave-safe bowl, pour strawberry and raspberry jam and mix together. Microwave in 30-second intervals, stirring after each interval until the jam becomes runny or liquified. Spread evenly over hot cake.
  • Allow cake to cool completely.

Chantilly Cream

  • In a large mixing bowl or stand mixer, beat heavy cream, vanilla, and almond extracts until stiff peaks form.
  • In a separate mixing bowl, cream together softened cream cheese and mascarpone cheese until light and fluffy, about 2 minutes. Beat in powdered sugar until combined and smooth.
  • Gently fold whipped cream into the cream cheese mixture using a rubber spatula. Fold until just combined. Refrigerate until the cake is cooled and ready to assemble.
  • Spread evenly onto the cake with an offset spatula.
  • Garnish with fresh berries, cover, and refrigerate for at least 2 hours before serving.

Notes

✱ Nikki's Tips
  • Make sure the cream cheese and mascarpone cheeses are completely softened/room temperature. This will make for a smooth icing.
  • For a true white frosting use a clear vanilla extract.
  • Want a super-smooth icing? Sift the powdered sugar before mixing it into the cream cheese.
  • Keep in mind how hot your oven cooks (all oven temperatures are different) and watch the cake cook time. I like to check about 5 minutes before the earliest cook time to be sure it doesn't overbake.
  • You can serve this at room temperature. However, I wouldn't keep it out any more than 1 to 2 hours. I definitely don't recommend serving this cake outside in warm temperatures. The whipped cream icing melts quickly in the heat.
