Homemade Marshmallow Creme - once you've had it you may never buy it store bought again. It's so easy to make and it's like eating fluffy, fresh, heavenly marshmallow clouds. Just try not to eat the whole bowl at once =). Great for a cupcake filling
Croissant sandwiches with pesto, rucola, figs and prosciutto. I use fig jam and spinach instead of figs and rucola (because it's easier/more available), and it's delicious. My fiancé loves it and it's super easy.
