I'm planning to make a spice cake and was thinking of adding multiple fillings. Is it popular to add 3 different fillings to a torted cake?
I thought the spice cake would be good with apple pastry filling, caramel buttercream and maybe cream cheese pastry filling. But really, don't know if this will be too much? Maybe it's best to stick with only 2 fillings (2 of one flavor and then one other?) Thanks in advance for any advice.

Yes, people do use three fillings and yes, that sounds really good!

A spice cake has so much flavor already, I really think that just one flavor is necessary. If you want to go for two, I would use a thin layer of cream cheese and a thin layer of apple or caramel, for each layer of cake. But not a different flavor for each layer.

Thanks! I think I'm going to try it LaBellaFlor! I think getting 3 different flavors in one piece of cake sounds good, but don't want to junk-up what I hope will be a beautiful cake!!!

I think the combos you have posted sound delish and I would definitely try them!

In the few times that I do tort, I usually do more than just one flavor of filling. Those that you listed go very well together anyway so I think it will be great. (I mean, you're not using any weird freaky flavors! )

I think those flavors sound fantastic together, and I myself have been known to use 3 fillings in a cake, or at least 2 fillings plus the icing.

That said, I agree with the pp about the cake ITSELF having so much flavor, that the multiple fillings might be overkill. I did a delicious banana-apple cake for Fall last year, which of course had some spices in it (nutmeg, cinnamon) and paired it with a ganache, caramel, and cream cheese IMBC. It was good but you know what, it was too much. You couldn't taste the cake, yet at the same time the flavors of the cake competed with the deliciousness of the fillings. I prefer the multiple fillings on a simpler flavor of cake. JMO!

So by adding my dissenting opinion here I think you are realizing that the answer to your question is: do what you want!
