An oliebol (plural oliebollen is a traditional Dutch food. Oliebollen (literally oil balls) are traditionally eaten on New Year’s Eve and at funfairs. They are also called smoutebollen in Belgium. Sometimes it is referenced in English as Dutch donut.
They are said to have been first eaten by Germanic tribes in the Netherlands during the Yule, the period between December 26 and January 6. The Germanic goddess Perchta, together with evil spirits, would fly through the mid-winter sky. To appease these spirits, food was offered, much of which contained deep-fried dough. It was said Perchta would try to cut open the bellies of all she came across, but because of the fat in the oliebollen, her sword would slide off the body of whomever ate them.
