Me and Laurel created this cake in Approx. 8 hours...pretty good I guess.?. The bottom 2 layers are completely made of fruity pebble-rice krispies. The top 2 layers were actual cake, chocolate and red velvet, I do believe (complements to our mother). This was by far the biggest and most difficult cake we have done, but we had a BLAST and would love to do it again!
