They're not only delicious, but they can also be dangerously addictive.
A 2013 paper published by researchers from the University of Bordeaux suggests the ingredients in a chocolate chip cookie triggers the same addictive response in the brain as cocaine and marijuana.
A traditional chocolate chip cookie contains 2.5 teaspoons of sugar, which the study says induces some of the same responses as cocaine.
As for chocolate, it contains small amounts of a compound that trigger the same part of your brain as the addictive ingredient marijuana, THC, the study says.
The two ingredients together create a harmonious flavor that can double the addiction.
Now that makes perfect sense to crave the dangerously addictive treat.
