File this under "totally no-brainer," but when you're pressed for time, this is the simplest, fastest dessert idea. Or dessert equation, if you will.
One part seasonal fruit:
Fall: pears, Concord grapes, apples, Asian pears, figs
Spring: strawberries, apricots
Winter: Apples, dates, dried figs, citrus
Summer: berries, peaches, plums, cherries
Plus one part store-bought cookies
Plus one part chocolate (milk, white, or dark)
Equals the perfect dessert plate.
The next time someone asks you to bring dessert and you don't have the time or inclination to bake, here's your solution. This also works super well for weeknight dinners where you want to serve something sweet but can't deal with anything fussy.
