1 1/2 sticks unsalted butter
1/2 cup light brown sugar, packed
1 tsp vanilla
1 1/2 cup flour
1 tsp baking soda
Sea Salt for sprinkling
Preheat oven to 325°F.
Line cookie sheet with parchment paper
In a saucepan over medium heat, melt butter until it starts to caramelize. It should smell nutty and you will see brown bits at the bottom of the pan. Be careful not to burn the butter...if it burns, toss and start again.
Pour brown butter into a medium bowl and stir in brown sugar and vanilla. In a small bowl whisk together flour and baking soda and add mixture to the butter and sugar. Let cool to room temperature.
Roll cookies into balls the size of large marbles and sprinkle with sea salt and press lightly into the tops of cookies.
Bake 15 minutes or until lightly golden. Don't overcook or they will be very dry and crumbly.
