How do you make your strawberry cake? Is it a box mix? If so, how about using a white cake mix and adding raspberries and raspberry flavoring to get the flavor you want? If it's scratch sub raspberries for the strawberries. Whenever I use lemon curd I always put down a thin layer of vanilla buttercream also. I just like that flavor, not necessary. I also have added lemon flavor to my buttercream for filling - people love it - more like a lemon cream.
