In a large bowl, combine the cake mix, eggs, orange juice and oil; beat on low speed for 30 seconds. Beat on medium for 2 minutes. Fold in blueberries and peels. Pour into two greased and floured 9-in. round baking pans.
Bake at 350° for 20-25 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.
For frosting, in a small bowl, combine cream cheese and butter until fluffy. Add the confectioners' sugar, orange juice and peels; beat until blended. Fold in whipped topping.
Spread frosting between layers and over the top and sides of cake. Refrigerate until serving. Yield: 12 servings.
