I knew how to make oil-free steamed bread, so I made a chewy version.

You could use juice or coconut milk instead of milk.

To get the marbled effect, when the dough is done, fill all the muffin cups halfway. Mix in a tablespoon of cocoa powder (or instant coffee or matcha) to the remaining batter and pour into the half-filled muffin cups. Drag a toothpick through the batter to swirl the two batters.

If it's a bother, you can just make two different types of batter without the marbleized effect. Recipe by nathu
