Does anybody know how many cups of batter the Wacky Cocoa Cake makes? I am looking at the recipe that has 3 cups flour and 2 cups sugar. Does it rise pretty much the same as a regular cake mix? I used to make this cake all the time when I was in Jr. High, but am fuzzy on the details now. (that was quite a while ago)

Have to make an eggless cake for a friend's son and just want an idea of what to expect.
