This is from Martha Stewart's Kids magazine. They developed it to be tasty for adults and good for one year olds to eat. You could probably give it to younger babies who are eating solid or sort of solid food, too. I cut this in half and used two 9"x13" pans instead of two 13"x18". The cake ends up being about 8" square with 4 layers or 2 layers. We cut our "half cake" into 16 pieces, so I am estimating 32 pieces for the larger, although I think it would be hard to cut the pieces that small. :) Plus the larger version makes 20 petit fours. Cook time does not include cooling time.
