Based on the presumption that the ingredient quantities are all a direct function of the volume of the finished cake, you need to find the proportion that represents the relationship of the two volumes. Since the thickness is the same for both sizes of cake, the correct proportion can be found by dividing the surface area of the sheet cake by the surface area of the round cake.

So multiply each of your ingredients by 3.6. That may be difficult for some of the ingredients. For example, if the round cake calls for 1 egg, you might consider putting in 3 whole eggs plus the white of a 4th.

Good luck.

If 8" is the diameter, it's 14.3 times as much of everything.
