Hi! I'm making a birthday cake covered in fondant. I want to do a two tier. Bottom tier I'm thinking of using a 8 inch x 2 inch and top tier a 6 inch × 2 inch. My question is how many layers should I do cake and filling. Last time I did two 8 inch with one filling layer...and same with the 6 inch I did two cakes with one filling layer. It turned out ok..but I feel like the cake layers were thick and it might have turned out nicer if I maybe cut them in half and layered with more filling....what do you guys think? What ratio do you guys use for cake and filling layers ? 

I typically do 2 layers of cake .... cutting them in half. I bake bake in the 3 inch pans and end up (if doing 2 layers) with 4 layers. I assemble from bottom up  .... cake, filling, cake, icing, cake, filling, cake. presentation is really nice when cut. My "layers" end up being 1 1/4 inches. 

I see that sounds like it would look really nice! Thanks I'll try that. I need to get 3 inch in thickness baking pans. All mine are 2 inches.
