Laura,
I know the feeling well. My birthday is the end of March. There is the standard Sponge Cake either from scratch or a Kosher for Passover box mix. There are all sorts of mixes available out there.
My mother made a Hazelnut Torte one time. Its layers were split horizontally and filled with whipped cream. She also made Meringue Cakes. You make a batch of sweetened meringue and pipe it through a large tipped pastry bag into swans and curlie-cues and one or two 9" circles with a lip in it. To assemble place one circle on platter, fill with sweeted fruit like strawberries then whipped cream, top with next layer and repeat filling and decorate the top with the swan and curly-cues and whipped cream.
