The chocolate souffle wants to be eaten the minute it leaves the oven, and National Chocolate Souffle Day is a good reason to let it. Whisk one up at home, or let a kitchen do it for you and be at the table when it lands.
No founder or establishing record for the day has been located. Nothing in the Federal Register carries the name, and the digitised run of Chase's Calendar of Events in HathiTrust does not list it.
The proteins that get an egg white to foam are largely not the proteins that keep it standing. A 2025 study in the Journal of Food Science pulled the two jobs apart: ovotransferrin, ovalbumin and ovomucoid did most of the foaming, while ovomucin, avidin and lysozyme took over the holding as the foam stood. National Chocolate Souffle Day is the day for a dessert that asks an egg white to do both jobs at once.
France has a settled definition of the dish, and it puts the difficulty in plain sight. The one the national language dictionary still quotes, from a gastronomic reference of 1962, is a puree bound with egg yolks off the heat. Into that go whites beaten to snow, and it is the whites that guarantee the rise in a moderate oven.
So the definition gives the whites the whole job of rising. Everything difficult about a souffle sits in that one clause.
DEALS & OFFERS
National Chocolate Souffle Day ran on February 28. Here’s who celebrated with offers this year.
In 1733 the Earl of Chesterfield's chief cook published a volume of his recipes in London. Vincent La Chapelle's The Modern Cook has an entry among the omelets called Omelet puff'd with Kidney of Veal. It is a souffle, and it is built on a roasted calf's kidney.
The method is already the modern one. Twelve yolks go in with cream, the whites are whipped "into Froth or Snow" and beaten back through the mixture, and the pan cooks slowly with a red hot iron held over it. Then the cook turns it out and sets it on a stove "that it may puff or rise", powders it with sugar, and is told not to touch it.
Nowhere in that volume does the word souffle appear; the recipe settles for puff'd. The French edition of 1742 carries the same recipe under the name it still has: Omelette soufflee, au Rognon de Veau.
The form was still not only a dessert in 1814. Antoine Beauvilliers, who ran the Grande Taverne de Londres in Paris, named five souffles in the first volume of L'Art du cuisinier, and every one of them is poultry or game.
The sweet souffles sit in his second volume, and one of them opens the door. His potato-starch souffle ends with a line telling the cook it can be made with vanilla, with rose, or with chocolate.
A year later Marie Antonin Careme was serving one. Le patissier royal parisien puts Le souffle francais au chocolat among the entrees of a spring menu for twelve covers, and his index of souffles francais runs through vanilla, Moka coffee, cocoa and chocolate.
The word took longer to settle than the food. The Tresor de la langue francaise dates souffle as a noun for the dish to 1829, in Boiste's dictionary, where it is defined as a light floury dish made in a portable oven.
The dish reached print long before the day did. The American calendar entry is much later and much thinner: no creator has been located for National Chocolate Souffle Day, and its earliest dated trace is a third-party holiday listing archived in December 2013.
TIMELINE
WHY THIS DAY MATTERS
A souffle stands on proteins that unfolded around air.
Whipping forces each coiled egg-white protein to unfold at the surface of an air bubble, its water-loving parts staying in the liquid and its water-fearing parts pushing into the air, and the unfolded proteins bond into a net around every bubble. Heat makes the trapped gas expand, and the net has to solidify before the bubbles burst.
Souffle is one of the rungs on Beauvilliers' ladder of boiled sugar, which climbs from the lisse to the boulet, and a cook tests for it by lifting a skimmer out of the pan and blowing through the holes until little bubbles of sugar come out. The Encyclopedie had printed that test in 1754, and the dictionaries do not record souffle as a noun for food until much later.
Iowa State University's food-preparation lab manual builds its egg-white foam session around a chocolate souffle, asking students to watch the recipe and say how the egg white foam is combined with the chocolate mixture. Its other pre-lab question is simply when the sugar should go into the whites.
AT A GLANCE
MYTH VS FACT
Slamming the oven door will bring a souffle down.
Cook's Illustrated mixed batters for muffins, yellow cake, angel food cake and a cheese souffle, loaded them into hot ovens, and opened the door for a hard slam just before each one reached its maximum height. Every one of them survived, and the test kitchen's verdict was that slamming makes no difference.
The first souffle recipe was printed in 1691.
The book that claim points to is Massialot's Le Cuisinier royal et bourgeois. Its 1693 Paris edition names omelettes 37 times, and the word souffle is not in it.
Careme's petits souffles au chocolat are an early chocolate dessert souffle.
They are petits fours. The recipe grates four ounces of chocolate into sifted sugar worked with an egg white, and the stiff paste goes into small paper cases and bakes in a slow oven until it lifts above the rim.

No. It is an unofficial observance rather than a public holiday, and the Federal Register carries no document naming it, so offices, banks and schools stay open.
