Strangely enough, this chocolate chip cookie was made in the microwave. It comes together easily and is a good way to enjoy a sweet treat without making dozens of cookies.
In a small bowl, melt the butter. Mix in the brown sugar until it is well incorporated, and add in the milk, flour and salt. Continue mixing until the mixture comes together into a dough. It should be Play-Doh consistency—not dry and crumbly but also not too sticky to handle. If the dough won't come together, mix in just tiny splash of milk until it does. If it is too sticky, mix in just a tiny bit of flour until you can roll it in your hands.
Once you reach the desired consistency, fold in the chocolate chips.
Place the dough onto a small piece of parchment paper on a microwave-safe plate and press it down into a circle until it is about one-half inch thick.
Place in the microwave and cook on high for one minute. Allow the cookie to cool a bit before enjoying.
