What is the name of the Thai dessert street food made with glutinous rice and mango?

The Thai dessert street food made with glutinous rice and mango is called mango sticky rice.

In Thailand, it is known as khao niao mamuang. The dish combines steamed glutinous rice with sweetened coconut milk and ripe mango, often with a little salt to balance the sweetness. Extra coconut sauce, toasted sesame seeds, or crisp yellow mung beans may be added on top.

The rice is not ordinary long-grain rice. Glutinous rice becomes especially soft and cohesive when steamed, allowing it to absorb the coconut-milk mixture without becoming a loose pudding. Popular Thai mango varieties include Nam Dok Mai and Ok Rong, both prized for their fragrance and sweetness.

Mango sticky rice is strongly associated with Thailand, but related versions appear across Southeast Asia and South Asia, including Laos, Cambodia, Malaysia, and the Philippines. In Thailand it is especially popular during mango season, commonly from April into May. Coconut milk is central to many central-Thai preparations, while northern versions may use it less often.
