A long john donut is a rectangular, oblong yeast donut that is usually iced with chocolate or maple glaze and sometimes filled with cream. The long john donut is bar-shaped rather than a ring, and the name is common across much of the United States.

What is a long john donut?

A long john donut is an oblong, bar-shaped donut made from fried yeast dough, roughly the size of a hand. It has no hole and carries a flat top that suits a thick layer of icing.

Alternative names include bar donut, maple bar when topped with maple and, with cream inside, cream-filled bar or custard bar. The shape is a regional signal. In parts of California and the Pacific Northwest, the name maple bar is far more common than long john.

Why is it called a long john?

It is called a long john because of its long, narrow shape. Beyond that, the origin of the term is not well documented, and several folk explanations circulate without strong evidence.

Because the history is uncertain, treat any story naming a specific inventor or year with caution. What is certain is that the name is widely used for a rectangular donut in American bakeries.

What are the common long john toppings and fillings?

The common long john toppings are chocolate icing and maple icing, and the common fillings are vanilla custard and whipped cream. Many bakeries sell the same dough in all four combinations.

Version Topping Filling
Chocolate long john Chocolate icing None
Maple bar Maple icing None
Cream-filled long john Chocolate or maple icing Vanilla cream or custard
Plain glazed bar Clear sugar glaze None
Cinnamon sugar bar Cinnamon sugar None

Sprinkles, nuts and coconut also appear in some shops, but chocolate and maple are the classics.

How is a long john different from a round donut?

A long john differs from a round donut mainly in shape, and the shape changes how it eats. The long john has a flat top for more icing and a wider, softer center than a ring donut.

  • A ring donut has a hole, which lets the dough fry evenly and gives a lighter bite.
  • A long john has more dough in the middle, so it feels more filling.
  • Ring donuts are often glazed in one dip, while long johns carry a thicker, flat layer of icing.
  • Long johns take a filling more easily because there is room along the length.

How is a long john different from an eclair?

A long john is a fried yeast donut, while an eclair is a baked choux pastry. They look similar because both are long, iced and sometimes filled, but they are different pastries.

Feature Long john Eclair
Dough Yeast dough Choux pastry
Cooking Fried in oil Baked
Texture Soft, bready Thin, hollow, delicate
Filling Optional cream or custard Always cream or custard
Origin American bakeries French pastry

How do you make a long john donut at home?

To make a long john donut, roll risen yeast dough into a rectangle, cut it into pieces, let them rise again, fry them and ice the tops. The steps below are a general method.

  1. Make a soft yeast dough from flour, milk, sugar, butter, egg and yeast, and let it double.
  2. Roll it to about 1/2 inch thick and cut pieces roughly 4 inches by 2 inches.
  3. Rest the pieces on parchment for about 30 minutes until puffy.
  4. Fry in oil at 350°F for about one minute per side until golden.
  5. Cool on a rack.
  6. Dip the tops in chocolate or maple icing and let them set.

For a filled bar, slit the side with a knife and pipe in chilled custard before icing.

Does Holmesburg Bakery sell long johns?

A long john by name is not on Holmesburg Bakery’s recorded menu. Reviewers mention a chocolate rod as a favorite there, which is a long pastry, but published sources do not say it is a long john or an eclair.

The bakery is known for cream-filled and powdered cream donuts, plus items such as butter cake, cinnamon rolls and muffins, according to listings reviewed in November 2026. Prices and fillings are not published. If you want a long pastry with chocolate, ask the counter what the chocolate rod is and how it is made.

What does a long john taste like?

A long john tastes like a soft, lightly sweet fried bread topped with a thick layer of icing. Chocolate versions are sweet and slightly bitter, while maple versions taste of caramel and brown sugar.

The dough is the same airy yeast dough used for round donuts, so the bite is chewy and light. Because the donut is long, each bite has a different ratio of icing to dough, and the last bite often carries the most icing. A cream-filled long john adds a cool, smooth center that softens the sweetness.

Long john vs Bismarck vs maple bar: what is the difference?

A long john is the shape, a maple bar is a long john with maple icing and a Bismarck is a round filled donut. The names overlap in everyday speech, which is why they confuse people.

Name Shape Usual filling Usual topping
Long john Rectangle None or cream Chocolate or maple
Maple bar Rectangle None Maple icing
Bismarck Round Jelly, custard or cream Sugar or glaze
Cream stick Rectangle Cream Chocolate or plain

Regional use varies. A cream-filled long john may be sold as a custard stick in some places, so reading the case label or asking is the safest route.

How do you keep a long john fresh?

Keep an iced long john in a loose container at room temperature and eat it the same day. A filled one belongs in the refrigerator. Icing can sweat if the container is airtight and humid, so leave a small gap for air.
