I have been asked to make a double barrel cake. I have googled to get some insight but I still would like to ask all of you if my thought process seems correct. So the client wants a 6 inch round by 18 inch high cake. I thought about making 3 sets of 4 inch cake (2 inches each layer) and then have rice krispies formed for the other 4 inches, all with cream in-between each layer, all doweled with 3 full length dowels into the 10 inch base drum.
1.would the RK layer be best on the top or split alternating with the cake. for example 4 inches of cake/ RK/ 4 inches of cake / RK / 4 inches of cake
2.can this be done with buttercream and then fondant on top?
3. would the placement of the cake circles be every 4 inches of cake? needed? or if I construct it as my example in question one, a cake circle on top and under the RK?
Is this even possible or nuts for considering?
Any insight and suggestions would be most appreciated.
Thanks so much!
