It's National Donut Day: Sweet Food Quizzes to Celebrate

The first Friday of June rolls around and suddenly half the internet is holding a glazed ring up to a window for the perfect lighting. Welcome to National Donut Day — a holiday that, against all odds, has an actual origin story. The Salvation Army launched it in 1938 to honor the "Donut Lassies" who fried dough for soldiers in the trenches of World War I. Nearly a century later we mostly just use it as an excuse to eat sugar before lunch. No notes.

Donuts deserve a quiz, but they also deserve company. So we've pulled together the four sweetest quizzes on Quizzy — a full dessert flight you can run through with a coffee and a Boston cream. Here's the lineup.

Start Broad: Desserts Around the World

Before you specialize, go wide. The Desserts Around the World quiz is your warm-up lap — and a humbling one. You think you know dessert until you're asked to place a pastel de nata, a kunafa, a mochi, and a Pavlova on the right continent. (Quick spoiler: Australia and New Zealand will fight you over that last one until the heat death of the universe.)

The donut itself is a beautifully global object. The Dutch had oliebollen. Germany has the Berliner. India has gulab jamun and the savory-leaning vada. Every culture, it turns out, eventually arrives at "fried dough, and then more." Take the quiz and you'll never look at a bakery case the same way.

The "hole" in the donut is often credited to a 19th-century sea captain named Hanson Gregory, who claimed he punched out the soggy middle so the dough would cook evenly. Whether that's true or a great piece of marketing is exactly the kind of thing these quizzes love.

Go Decadent: Chocolate Desserts

If donuts are the entry point, chocolate is the deep end. Our Chocolate Desserts quiz covers everything from molten lava cake and Sachertorte to the difference between ganache, ganache, and — surprise — more ganache. There's real chemistry hiding in here too: why tempering matters, what "single origin" actually means, and the reason a chocolate fountain works the way it does.

It's a great pairing with National Donut Day specifically because the chocolate-frosted donut is, statistically, the people's champion. Lean into it.

Earn It: The Baking Quiz

Here's where the casual sugar fans get separated from the people who own a kitchen scale. Our Baking quiz is the technical one. Yeast versus baking soda. What gluten actually does. Why your cookies spread into one giant continent that one time. (Butter too warm. It's always the butter.)

Donuts straddle both worlds — the classic raised donut is yeasted, while the cake donut leans on chemical leavening — so this quiz quietly explains the science behind the very thing you're celebrating. If you want to understand why the donut you're eating tastes the way it does, this is the round.

Cool Down: Ice Cream

End on the easy, joyful note. The Ice Cream quiz is pure summer — gelato versus ice cream, what makes soft-serve soft, the history of the cone, and why brain freeze happens (it's your trigeminal nerve overreacting, and now you know). It's also the natural sequel to donuts, because the donut ice cream sandwich is a real thing humans invented and we should all be grateful.

And here's a fun bit of trivia to drop at the table: gelato has less fat than American ice cream, not more, despite tasting richer. The secret is that it's churned slower, so less air gets whipped in, which makes it denser and more intense per spoonful. The quiz is full of small reversals like that — the kind of fact that sounds wrong until you understand the mechanism, and then it sounds obvious.

A Quick History of the Thing You're Celebrating

Since you're here for the donut specifically, it's worth knowing the timeline. The fried-dough concept is ancient and basically universal, but the modern American donut owes a lot to Dutch settlers who brought olykoeks ("oil cakes") to New York centuries ago. The ring shape and its famous hole became standard in the 1800s. The first donut machine arrived in 1920, turning a homemade treat into an industrial one — and within a couple of decades the donut was a fixture of diners, police-station jokes, and Friday-morning office boxes everywhere.

None of that history will hand you a perfect quiz score on its own, but it's exactly the kind of context that makes these food quizzes click. Once you know where a food came from, the questions stop feeling like memorization and start feeling like a story you already half-remember.

Build Your Own Dessert Bracket

Want to make it a proper event? Run all four quizzes back to back and total your scores into one "Sweet Tooth Index." Over 80% across the board and you've genuinely earned a second donut. Under 50% and, well, the donut is its own consolation prize. There are no losers on National Donut Day.

If you'd rather chase the stories behind the food, our surprising food origins post is a perfect companion read — it covers the unexpectedly weird histories of dishes you eat without a second thought. And for the full tour of our food category, the world food quiz roundup maps out every cuisine quiz worth your time, from street food to fine dining.

So grab the donut, hold it up to the window, take the photo, and then put your phone down and actually find out how much you know. The bakery case is a textbook. Time to get tested.
