Wrap the lid of a steamer with a towel and tie at the handle of the lid (this prevents condensation from hitting the dough while steaming).
In a bowl, beat the egg and add the milk and sugar and combine. Then add the pancake mix and vegetable oil and mix well.
In muffin molds, place the cupcake liners and divide the batter equally into the cups. If you have rigid muffin cups, you don't need to use molds or tins. Or use ramekins as molds.
Add the water to a steamer and bring to the boil. When boiling, place the muffin molds and steam on high heat for about 15 minutes. Stick a toothpick in the center of the steamed bread. If it comes out clean, they're done.
