1-1/3 cups water
1/2 cup vegetable oil
1 tbsp. grated orange peel
3 eggs
1 tub Betty Crocker Rich & Creamy chocolate ready-to-spread frosting
1/3 cup whipping (heavy) cream
1/2 cup semisweet chocolate chips
2. Beat cake mix, water, oil, orange peel and eggs in large bowl with electric mixer on low speed 1 minute, scraping bowl constantly. Pour into pans.
3. Bake 8-inch pans 33-38 minutes, 9-inch pans 28-33 minutes or until toothpick inserted in center comes out clean. (Decrease bake time by 2-3 minutes if using dark or nonstick pan.) Cool 10 minutes; remove from pans. Cool completely, about 1 hour.
4. Fill layers and frost cake with frosting. Heat whipping cream in 1-qt. saucepan over medium heat until hot (do not boil); remove from heat. Stir in chocolate chips until melted and smooth. Let stand 5 minutes.
