Big doings in the world of donuts this weekend, beginning with Cronuts, which just celebrated their ninth birthday.

This Saturday, May 21, Dominique Ansel Bakery will donate 10% of its Cronut sales to City Harvest’s Share Lunch, Fight Hunger (SLFH) campaign. The drive, which will be in force through June 3, is dedicated to feeding more than 15,000 New York City children and their families for the entire summer.

Fighting hunger is a cause near and dear to owner Dominique Ansel, who told Broken Palate:

I grew up humbly. My parents didn’t have much money and it was difficult to put food on the table. I know what it’s like counting pennies to buy food. It’s important for me to give back.

You can help the bakery achieve its goal by stopping by the store on Saturday and picking up a couple of its signature pastries, though be warned: The limit of two per customer remains the house policy. Who’da thunk it, but after nine years, the Cronut is as popular as ever.

Dominique Ansel Bakery, 189 Spring Street (bet. Sullivan and Thompson Sts.), 212-219 2773.

When Worlds Collide

After you’ve polished off your Cronuts, head over to Bed-Stuy, which will be the site this weekend of the second annual Chocolate Doughnut Festival. For the occasion, Fan-Fan Doughnuts will partner with Guittard Chocolate Company to deliver such delectable and sometimes exotic delights as “Foraging,” which combines hazelnut and candied mushrooms, and “Starry Night,” which blends chocolate with caramel. Donuts will sell for $4 apiece. The festival is scheduled to run from 9 a.m. to 6 p.m. today through Sunday or until the goodies have all sold out.

Fan-Fan Doughnuts, 448 Lafayette Avenue, Brooklyn, 347-533-7544.
