Chocolate Orange Truffle Cake

Heat oven to 350 degrees F. Bake and cool cake as directed on package for two 8 inch or 9 inch round pans, except add orange peel with the water, oil and eggs. Fill layers and frost cake with frosting.

Heat whipping cream in 1-quart saucepan over medium heat until hot (do not boil). Remove from heat. Stir in chocolate chips until melted and smooth. Let stand for 5 minutes.

Carefully pour chocolate mixture onto top center of cake. Spread to edge, allowing some to drizzle down side. Refrigerate for about 1 hour or until chocolate is set. Cover and refrigerate any remaining cake.
