Which doughnut variety is filled with fruit preserves or jelly after frying?

A doughnut filled with fruit preserves or jelly after frying is called a jelly doughnut.

Jelly doughnuts are usually made from a round piece of yeast-raised dough without a central hole. After frying, the doughnut is injected or split and filled with jam, jelly or another fruit preserve, then often coated with sugar.

The filled doughnut has many regional names and traditions. In Israel, the sufganiyah is a jelly-filled doughnut strongly associated with Hanukkah, while German and Central European filled doughnuts have their own names and customs.

Not every filled doughnut is a jelly doughnut. Custard, cream, chocolate and fruit fillings are also common, so the defining detail here is the fruit-preserve filling rather than the doughnut’s shape or coating.
