Preheat oven to 325 degrees F, grease an 8x8” baking dish, set aside.

Melt white chocolate and butter together in a microwave safe bowl, or on the stovetop over low heat. Stir until smooth and glossy. Set aside.

In the bowl of a standing mixer, beat eggs and sugar together for 30 to 60 seconds, or until pale and thick.

Add melted white chocolate/butter mixture and vanilla and stir on low speed until batter is smooth.

Add flour and sea salt and mix on low speed until just incorporated and there are no lumps.

Stir in chopped white chocolate.

Pour batter into prepared pan; bake until the top is set and the brownies are only very slightly “jiggly” and just barely begin to brown. 30 to 35 minutes

Once brownies are baked, remove from oven and put the pan on a wire cooling rack to cool completely.
