Cookies is the name used by Americans and Canadians for what may more normally be called biscuits. Why they have chosen to do this is a mystery, as the word biscuit is perfectly reasonable and serviceable.
A single chocolate chip cookie is around 50 calories and as it is a physical impossibility to eat a single chocolate chip cookie, this adds up to quite a lot of calories before the packet is empty. The same phenomena is attached to Jaffa Cakes, they too are incredibly more-ish and the packet is either unopened or empty. You could argue that Jaffa Cakes are not biscuits but cakes, the manufacturers certainly did, and after legal argument had been heard and considered, a court ruled that they were indeed a cake, meaning that VAT is not paid on Jaffa cakes in the UK, and therefore they have no place in this article because it is ostensibly about cookies and or biscuits. That being said, Jaffa Cakes are made with the same kind of unhealthy, refined sugars that are used in the production of biscuits and cookies.
For each chocolate chip cookie you consume, you would need to walk for a good 15 minutes just to burn off the energy contained within it. Alternatively you could jog for 6 minutes, swim for 4 minutes, cycle for 8 minutes or engage in vigorous sexual activity for 30 seconds.
TL;DR - Conclusion.
It is possible to combine these activities so as to reduce the boredom somewhat, but it would require the use of a pocket calculator to even begin to work out how long you would need to ride your bike for, before switching to jogging,swimming or cycling.
