Mango Cream Cake

I misplaced the instructions for this recipe. What I found was just the ingredients. When I make this, I figure out how to prepare it which is fine because the cake is prepared like Chiffon Cake, and the rest are easy to figure out. Anyway, it can be determined just by looking at the ingredients.
