The experiment did have a control condition (the different amounts of cheese), a dependent variable (the time it took to complete the course), an experimental manipulation (the varying amounts of cheese), and an independent variable (the size of the reward).

The confusion might stem from interpreting the setup, but given the details, all components for a basic experimental design are accounted for. The mistake here is in the interpretation of the question's phrasing; it seems to imply something was missing, but based on standard experimental design components, nothing was.
