For the Tangerine Magic Cake, place all ingredients (except cake base) in a large, well-sealed bowl. Shake vigorously. Place cake ring around cake base and pour in mixture.
Smooth out and place in freezer for 15 minutes or refrigerate for 1 hour.
Preparation Tip:
The tangerine magic cake is prepared in a flash. My grandmother always had frozen biscuit base. So she conjured up a kind of ice cream cake in no time when unannounced guests came.
