Once the ingredients are on the conveyor you are going to have to switch them off it so that they are able to get to the exits.
I earned a silver crown thingy on the map.
Ok, I couldn't wait any longer so I tried on my pc and started out immediately with one hand switch to get 2 colorbombs sprinkles together and then later used a lollipop hammer on the last piece of the remaining cake when I thought nothing else would work on it.
Then I matched a colour bomb with a stripe and cleared a most of the blockers.
