Gajak is prepared with sesame seeds and jaggery with a method of preparation which is time-consuming. It takes about 10–15 hours to prepare 5–8 kilograms of gajaks. The dough is hammered until all the sesame seeds break down and release their oils into the dough.

One kilogram of Gajak requires about one-fourth of jaggery to sesame. Varieties can include dry fruits.
