What kind of icing goes best with lemon cake?

I love to do lemon cake with raspberry filling and regular buttercream! Regular buttercream is good with lemon cake, so is cream cheese icing. You can add a little lemon juice or lemon extract to either of those if you wanted to add to the lemon-y flavor.

French vanilla, raspberry, blueberry... I'm making lemon cakes for this weekend. I can't wait to hear other ideas!

I LOVE IMBC with lemon cake. You can add lemon extract if you want, but its good without it. Lemon cake, raspberry filling and IMBC is one of my favorite cake's to eat. (after coconut. I'm a coconut cake dork!)

I agree with SweetestThing, raspberry and bc goes wonderfully with lemon cake, I like to spread bc then a layer of raspberry directly over the bc. Blueberry sounds good too, I just find that raspberry is more popular.

I just made a lemon pound cake with lemon curd filling and buttercream icing with just a little lemon extract, and it was really delicious. I thought the all lemon combo might be too much, but it was great!
