Preheat oven to 350. In a microwave safe bowl put the stick of butter and white chocolate chips. Cook in microwave for 1 minute, take out and stir so that everything is melted together and smooth. Next add the 2 eggs and stir with a wooden spoon. Next add the sugars, flour, and pinch of salt, and add 1/2 tsp of the Himalayan Rock Salt and the vanilla extract. Divide the mix into two, and in one of the halved batter bowls add the chocolate chips. Spread this mixture into a greased (cooking spray covered) 8 x 8 brownie pan. Spread the remaining batter over the one with the chocolate chips, and add the remaining 1/2 tsp Himalayan Rock Salt by sprinkling it evenly across the top.
