Pre-heat the oven to 350F. Cream the butter. Slowly add the sugar while continuing to beat the butter.
Add the egg and beat.
Add the flour and salt.
In a small container, combine the vanilla, baking soda and hot water. It will fizzle a bit.
Pour the vanilla mixture on the flour, and start beating slowly, and accelerate until smooth.
Add the chocolate chips and blend briefly.
Drop in small teaspoons on an ungreased cookie sheet - these cookies will spread quite a bit. Makes 40 cookies.
Bake for 13 minutes at 350F.
