Sooooo many things, most of the time homemade. I love homemade cookies, cakes and cupcakes with buttercream frosting, fruit pies, mousses...
It really changes with the seasons. In the spring, I like lightly flavored things, like key lime pies and lemon meringue pies. Citrusy flavores. In the summer, cold things, like ice cream, icebox cakes, Jello (yes, I know where gelatin comes from, and yes I'm mostly vegetarian, but, omfg, I love Jello), boston cream pies...
In the fall, I LOVE fruit pies and cobblers, like apple pie, apple streudel, peach cobbler, pear upside down cake, etc. In the winter, cookies! Winter is cookie season. And fudge. Mmmm.
