Preheat the oven to 180 degrees celsius
Beat/cream softened butter, brown sugar, egg and vanilla together
Add all remaining dry ingredients excluding the chocolate chips and mix well
Stir in chocolate chips, the mixture will be a little sticky
Wet your hands, and roll tablespoonfuls into balls, place on a lined tray
Use a wet fork to gently flatten each ball
Bake for 8-10 minutes (this gives a soft chewy cookie) you can also bake for a little longer 12-15 mins if you prefer a crunchy cookie
Cool for a few minutes on the tray then transfer to a cooling rack. Store in an airtight container. Eat them often, keep them next to where you breastfeed so you always have a snack on hand
