Preheat your oven to 350 degrees. Spray 6 oven-safe ramekins with cooking spray.
In a large mixing bowl or the bowl of a standing mixer, add butter and sugar. Cream together until light and fluffy. Then, add the vanilla and egg and mix well.
To the bowl, add the flour, salt and baking soda. Mix until just combined.
Without overmixing the dough, gently fold in the chocolate chips until evenly dispersed.
With an ice cream scoop, portion the cookie dough evenly into the greased ramekins.
Place the ramekins on a baking sheet and transfer them to the oven to bake for 15 to 18 minutes or until just set and the edges begin to brown.
Fresh from the oven, I like to sprinkle a little flaked sea salt. Let the cookies cool for 5 to 10 minutes before serving straight from the ramekin Á la mode (with ice cream).
