1 package Pillsbury™ Moist Supreme® White Premium Cake Mix
1 cup water
1/4 cup Crisco® Pure Vegetable Oil
4 large eggs
2 (8 oz.) containers mascarpone cheese
2 cups (1 pt.) heavy cream
1 1/2 cups sugar
2 teaspoons vanilla extract
1 1/4 cups brewed Medaglia d'Oro® Italian Roast Espresso Coffee
1 tablespoon unsweetened cocoa powder
Semi-sweet chocolate curls for garnish
HEAT oven to 350°F. Coat 15 x 10-inch baking pan with no-stick cooking spray. Blend cake mix, water, oil and eggs in medium bowl with electric mixer on low speed until moistened. Beat 2 minutes on low speed. Pour batter into prepared baking pan. Bake 23 to 25 minutes or until a toothpick inserted in center comes out clean. Cool in pan 15 minutes. Remove to wire rack to cool completely.
COMBINE mascarpone cheese, cream, sugar, vanilla and 1/4 cup coffee in large bowl with electric mixer on low speed until blended. Beat on high speed until thickened, about 5 minutes.
TRIM outer edges of cake with serrated knife; cut crossswise into 3 (10 x 4-inch) pieces. Split each piece in half horizontally, to make 6 (10 x 4-inch) cake layers. Brush cut side of cake layers with coffee. Repeat with remaining coffee.
PLACE 1 cake layer on serving platter. Spread top with 1 cup filling; dust with cocoa powder. Repeat to add second and third cake layers. Frost top and sides with about 2 cups filling. Dust with cocoa powder just before serving. Repeat to make another loaf. Garnish with chocolate curls, if desired. Cover and chill several hours before serving.
