White Velvet Layer Cake with Strawberry-Raspberry Mascarpone Buttercream

 For the Cake

2 1/2 cups (280 grams) sifted White Lily® Self-Rising Flour

2 cups (400 grams) granulated sugar

1/2 cup (1 stick/113 grams) butter, at room temperature

1/4 cup (48 grams) shortening

1/4 cup (56 grams) coconut oil, or favorite vegetable oil

1 cup (240 ml) buttermilk, at room temperature

3/4 cup (180 grams) egg whites (about 6), at room temperature

2 teaspoons (10 ml) almond extract

1 teaspoon (5 ml) vanilla extract

 

For the Frosting

1 to 1 1/2 recipes Strawberry-Raspberry Mascarpone Buttercream (if making a rosette cake)

 

Spray three 8-inch round cake pans with cooking spray. Line bottoms with parchment paper circles.

 

Using an electric stand mixer fitted with paddle attachment, mix self-rising flour and sugar on low speed (stir) until well combined and aerated, about 1 minute. Add butter, shortening and oil and mix on slow speed until thoroughly combined. Mixture will be very thick.

 

In a 2-cup glass liquid measuring cup, whisk together buttermilk, egg whites and extracts using a fork until well blended. Slowly add half of the liquid mixture to the batter and mix on low speed. Increase mixer speed to medium and beat until thoroughly combined, scraping down the sides of bowl as necessary with rubber spatula, about 2 minutes. Add remaining liquid mixture and beat just until smooth and thoroughly combined, again scraping down the sides of bowl as necessary, about 1 minute.

 

Pour batter into prepared pans dividing evenly (a little over 2 cups of batter per cake pan). Smooth tops evenly with rubber spatula and then rap each pan on counter surface 2 to 3 times to expel any air bubbles. This step will create a nice level cake.

 

Bake in preheated oven until a toothpick inserted into center comes out clean, about 25 to 30 minutes.

 

Cool cakes in pans on wire racks for 10 minutes. Remove from pans and cool completely. Wrap each cake layer tightly in plastic food wrap and keep at room temperature until ready to fill and frost.

 

For the Frosting:

2 cup butter, softened, unsalted

4 oz mascarpone cheese chilled

6 tbsp Strawberry-Raspberry Sauce (below)

2 tsp pure vanilla extract, optional

4 to 4-1/2 cup powdered sugar

Pink food coloring, optional

 

Beat butter on medium speed using an electric stand mixer fitted with paddle attachment until creamy.

Add mascarpone cheese, Strawberry-Raspberry Sauce and vanilla.  Beat until fully incorporated.  Gradually increase mixer speed to high and continue beating until light and fluffy.  Scrap down the sides of bowl as necessary with rubber spatula.  Gradually add powdered sugar until well combined, beating on low-speed.

Beat on high-speed about 2 min until well combined and smooth.  Tint buttercream with pink food coloring if desired.

 

Strawberry-Raspberry Sauce

8 oz raspberries, red, fresh

8 oz strawberries, hulled, fresh

1 tsp freshly squeezed lemon juice
