Ingredients

  • 1/2 cup butter, softened
  • 1-2/3 cups sugar
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 1-3/4 cups all-purpose flour
  • 1/2 cup baking cocoa
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1-1/3 cups water
  • 2-1/2 cups heavy whipping cream
  • 1/3 cup confectioners' sugar
  • 1 envelope unflavored gelatin
  • 3/4 cup thawed frozen orange juice concentrate
  • 3/4 cup sugar
  • 1/2 cup Grand Marnier, divided
  • 3 tablespoons grated orange zest

Method

  • Preheat oven to 350°. Line bottoms of two greased 8-in. round baking pans with parchment paper; grease paper.
  • In a large bowl, beat butter and sugar until crumbly. Add eggs, one at a time, beating well after each addition. Beat in vanilla. In another bowl, whisk flour, baking cocoa, salt, baking soda and baking powder; add to creamed mixture alternately with water, beating well after each addition.
  • Transfer batter to prepared pans. Bake 25-30 minutes or until a toothpick inserted in center comes out clean. Cool in pans 10 minutes before removing to wire racks; remove paper. Cool completely.
  • In a chilled large bowl, beat cream until it begins to thicken. Add confectioners' sugar; beat until soft peaks form. Refrigerate, covered, 1 hour or until very cold.
  • For filling, in a small saucepan, sprinkle gelatin over orange juice concentrate; let stand 1 minute. Stir in sugar. Heat and stir over low heat until gelatin is completely dissolved. Stir in 1/4 cup Grand Marnier and orange zest. Let filling stand at room temperature just until spreadable, stirring occasionally. (If mixture becomes too firm, warm in microwave to soften, about 10-15 seconds.)
  • Meanwhile, using a long serrated knife, cut each cake horizontally in half. Brush layers with remaining Grand Marnier. Place one cake layer on a serving plate; spread with one-third of the filling. Repeat twice. Top with remaining cake layer.
  • To frost cake, cut a hole in the tip of a pastry bag or in a corner of a food-safe plastic bag and insert #829 or other large star pastry tip. Gently stir whipped cream; spoon into bag and pipe onto top and sides of cake. Refrigerate at least 4 hours before serving.
