The traditional bunny cake was invented by Baker’s Coconut around 1970 when it was included in a promotional booklet (the 2nd in the series) of “cut-up” animal cakes. As far as I can tell, the only one that really took off was the bunny. The hobby horse cake was not so popular. Its demise may have something to do with the fact that you had to be an architect to figure out the blueprint. Anyhoo, since then, there have been several versions of the diy bunny cake, but this one remains my favorite….
