This small-batch chocolate chip cookie recipe makes the softest, most chewy chocolate chip cookies in the world!
In a large bowl using a hand mixer, beat together butter, brown sugar, granulated sugar, and salt for 2 minutes until creamy. Add egg yolk and vanilla extract and beat until combined. Add flour mixture and beat on low speed just until combined. Mix in chocolate chips gently. Don’t over mix. The less you mix, the softer the cookies will be.
Divide your dough into 6-7 even dough balls (45g each) and place them on your prepared cookie sheet, evenly spaced apart.
Bake for 10-11 minutes, until cookies are very slightly browned and the center is still soft. They will appear underbaked, but this is what you want. Pull the cookies out of the oven and allow to cool for 15 minutes on pan. Then gently transfer cookies to a wire rack to cool completely.
