Preheat oven to 360F and line baking sheets with silicone mats or parchment paper. Whisk together flour, salt, and baking soda, then set aside.

In a stand mixer or large bowl with an electric hand mixer, beat butter and granulated sugar on high until light and fluffy. Add brown sugar and mix until well-combined.

Stir in the vanilla extract, then mix in the eggs one at a time, scraping down the bowl after each addition.

Add the flour mixture to the wet ingredients and mix on low until almost combined. Fold in the white chocolate chips, reserving a handful if you plan to add them on top later.

Scoop two-tablespoon portions of dough onto the lined cookie sheets, spacing them 3 inches apart. Bake for about 10 minutes at 360F, or until the edges are golden. If adding reserved chips, bake for 8 minutes, add chips, then continue baking for 2-3 minutes.
