I have not made this recipe yet, but it sounds overly complicated in the directions. Hate that. What sounds easier and skips a step, is to buy a round angel food cake from your grocery store's bakery. Cut that up as it says, or cut more layers...like three layers instead of two. While you don't get the topper this one shows, you can still use some of the left over cool whip or strawberries.
I plan to make this with my version this summer. I'll try to come back with the results. In my opinion, the bakery's angel food cake would go much better than plain white cake.
