I would leave the word "cajeta" (in italics) and provide an explanation. One option is "(slow-cooked) thickened caramel sauce".

https://en.wikipedia.org/wiki/Cajeta
Cajeta is a confection of thickened caramel usually made of sweetened caramelised goat's milk. It is a type of dulce de leche. In Mexico, it is considered a specialty of the city of Celaya in the state of Guanajuato.

Cajeta is made by simmering goat's milk, or occasionally a sweetened liquid, stirring frequently, until its viscosity increases due to evaporation of water, and it becomes caramelized. While goat milk is the most usual base, other liquids or juices may be used.

In Celaya, and eventually the rest of Mexico, the confection of half goat's milk and half cow's milk became known by the name cajeta. Elsewhere, the milk candy is known as leche quemada or dulce de leche. It has analogues in the many Indian milk-based sweets, such as pera and milk fudge burfi, and in the opera fudge of the United States. Cajeta is eaten on its own as a sweet; as a spread or filling for breads and pastries, such as churros; and as a topping for ice cream.
