I don't have much baking experience but im making my sons first birthday cake. I baked it once to make sure I could do it first. It is a rubber duckie cake of a duck in a tub. The tub part is two sheetcakes. When I made it though I frosted it with buttercream and it tasted top rich and sweet. I thought maybe of putting a filling in between the cakes to distract from the buttercream. Any suggestions? [/i]

Just curious about your buttercream recipe? Unsalted butter? Salted?

I think last time I used salted but i am very open to suggestions of unsalted

What is your buttercream reciepe?

I use the wilton recipe at their site. Any suggestions for filling? I know that it can't be too fluffy bc of the buttercream on the outside. If someone has a lighter buttercream recipe that would help too. Thanks

raspberry preserves? or any other fruit...

icing is pretty much just sugar and fat, so it will be sweet. that always bothers adults more than the kids!
since he is young enough not to really care, maybe try a meringe bc, like imbc or smbc, they dont crust so are very different to work with, but are much less sweet than traditional bc recipes.

Could I do some sort of pudding or is it too light?

You can use pudding...use instant pudding, it calls for 2 cups of milk....use 1 cup, mix, let it set and then add whip cream to it...you can use real whipped cream, cool whip or pasty pride...they all work just fine....add a little at a time till you get the consistancy you want.

you might need to put a bc damn round the cake if you use a filling other than bc, or else if its a soft filing it may cause a bulge. i am lazy so always just use bc! or jam, but that will add to the sweetness.
