Finally back to update. I made the cake Laulor linked to. I don't have a picture- sorry! I realized we didn't get one of just the cake without ds.
I ended up making the cake twice. The recipe has is definitely is best as one 9x13 cake. I thought it would make a 9x13 and 8x8, but those were too thin. It took longer to bake that way, and the first ones I made weren't baked all the way through.
If you do make a 9x13 cake, I'd make half the amount of frosting. It was way too much!
The cake was good. I'd make it again, though it was somewhat labor intensive. Especially when I had to make the cake and frosting twice.
Definitely better than a boxed cake! Ds seemed to like it and the guests did too. Something different!
