1 (18 ounce) package orange cake mix
1 (1 ounce) package powdered orange juice
1 (3 ounce) package instant vanilla pudding mix
1 cup soft drink orange juice
Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 9-inch round cake pans.
Combine orange cake mix, orange juice, pudding mix and orange juice in large bowl. Stir until ingredients are well blended. Pour batter into prepared pans.
Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Cool in pan for 10 minutes, then invert onto a wire rack and cool completely.
