Bánh da lợn

Bánh da lợn, bánh da heo (lit. 'pig skin cake'), or bánh chín tầng mây (lit. 'nine-layer cloud cake') is a Vietnamese steamed layer cake made from tapioca starch, rice flour, mashed mung beans, taro, or durian, coconut milk and/or water, and sugar. It is sweet and gelatinously soft in texture, with thin (approximately 1 cm) colored layers alternating with layers of mung bean, durian, or taro filling.

Typical versions of bánh da lợn may feature the following ingredients:
 * Pandan leaf (for green color) with mung bean paste filling
 * Pandan leaf (for green color) with durian filling
 * Lá cẩm (leaf of the magenta plant, Peristrophe roxburghiana; imparts a purple color when boiled) with mashed taro filling

In modern cooking, artificial food coloring is sometimes used in place of the vegetable coloring.

A cake called kuih lapis, which is made in Malaysia and Indonesia, is similar to bánh da lợn. In the Philippines, a similar dessert and variant of kutsinta is simply called Vietnamese kutsinta and the Khmer of Cambodia call it num chak chan (នំចាក់ចាន់).
