Make this granita when you have an afternoon to yourself. Eat one alone, over the sink (pants optional.) Save the rest of the batch in the freezer; pull it out the next time you have people over. It's dessert, coffee, and after-dinner drinks all at once. —Rebecca Firkser
Pour coffee, liqueurs, and vanilla into a 9x13-inch baking dish.
Place in the freezer for 45 minutes to an hour, until the mixture starts to get icy. Using a fork, break up any slushy bits. Return to the freezer. Repeat every 30 minutes, until the mixture is completely frozen.
Serve with plops of sweetened whipped cream or ice cream!
