is a sweet chocolate rice porridge in Philippine cuisine. It is traditionally made by boiling sticky rice with cocoa powder, giving it a distinctly brown color and usually with milk and sugar to make it taste sweeter. However, dry tsampurado mixes are prepared by just adding boiling water. It can be served hot or cold and with milk and sugar to taste. It is served usually at breakfast and sometimes together with salty dried fish locally known as tuyo. The pudding becomes very thick and the lighter milk helps to "loosen" it. It's almost like eating "chocolate oatmeal". It can be eaten as a snack or dessert as well. I took this from Wikipedia . But from what I know its origin is from Mexico and there is a drink too named Champorado. I tried it and it's delicious ;)

"Who knows what champorado is?" - this is the word-order you need. You've already shown it's a question with "who knows", so you don't use a question word-order after "what".
