Hot chocolate is one of the most indulgent ways to warm up in the winter, and the Valrhona Hot Chocolate Festival will let you indulge while also giving back.

From Jan. 21 to Feb. 5, bakeries and pastry shops around the city -- including big names like Dominique Ansel Kitchen (home of the blooming hot chocolate), Laduree and Mah-Ze-Dahr Bakery -- will be selling specialty hot chocolates to help benefit Valrhona’s Clean Water Project.

The hot chocolate won't exactly be guilt-free -- the calories, of course, will remain -- but you'll feel a little better about your chocolate splurge, knowing that 50 cents per cup of hot chocolate, specialty or house, sold at participating bakeries will go to the luxury chocolate brand's charity.

Among the treats in the works is a hot chocolate from Epicerie Boulud that will include gingerbread spices, Abinao Valrhona chocolate and Valrhona cocoa. And the festival will kick off with an event at Laduree SoHo on Jan. 18 -- you can buy tickets ($35) here.
