I made a lemon cake and a lemon cream cheese frosting. Both are in the freezer awaiting their fate. The frosting is delicious, but it may be too sharp for a cake that is already lemon flavored. The cake will have 4 layers. I was thinking two of them with the lemon frosting and 2 to break it up. But with what? Whipped cream? Creme patisserie? Any flavor other than vanilla? Any ideas? ??? ???
