To make an orange cream cake, bake a traditional vanilla cake and add orange flavoring in the form of orange zest, orange-flavored gelatin or orange juice. DeliciouslySprinkled.com's recipe for orange cream cake uses an orange-flavored boxed cake mix.
To make LandOLakes.com's orange cream layer cake, preheat an oven to 350 degrees Fahrenheit. Grease and flour two 9-inch round cake pans. In a bowl, combine 1 3/4 cups all-purpose flour, 1 1/2 teaspoons baking powder, 1/4 teaspoon baking soda and 1/4 teaspoon salt. In a separate bowl, combine 1 1/2 cups sugar, 3/4 cups softened butter and 1 tablespoon orange zest. Beat the butter until creamy, then slowly add 3 eggs. Alternate between adding flour mixture and 3/4 cup of buttermilk, beating constantly, until just combined.
Divide the batter between the two pans and bake for 27 to 32 minutes or until a toothpick comes out clean. Let cool for 10 minutes before removing the cakes from the pans. In a bowl, combine 1/3 cup powdered sugar, 1/4 cup heavy cream, 1 8-ounce package of cream cheese, 2 tablespoons orange juice and 1 tablespoon orange zest.
Once the cake has cooled, place the bottom layer on a serving plate and top with the cream cheese mixture, reserving 1/2 cup of the filling. Top with the other cake layer, cover, and refrigerate. While the cake chills, combine 1 cup heavy cream with 2 tablespoons powdered sugar and 1 teaspoon grated orange zest. Add remaining filling, then beat at high speed until stiff peaks form. Frost the cake, then serve immediately or refrigerate for up to six hours.
