Toast the macadamia nuts in a dry skillet over medium heat for 4-5 minutes, stirring often, until golden and fragrant. Let them cool, then roughly chop.
In a medium bowl, whisk together the flour, cornstarch, baking soda and salt. Set aside.
In a large bowl, beat the dairy free butter, brown sugar and granulated sugar for 2 minutes until light and fluffy. Beat in the egg, egg yolk and vanilla until smooth.
Add the dry ingredients and mix on low speed just until combined. Fold in the white chocolate chips and toasted macadamia nuts, saving a small handful of chips for the tops.Cover and chill the dough for 45 minutes to keep the cookies thick and chewy.
Preheat the oven to 350°F and line two baking sheets with parchment paper. Roll the dough into 2 tablespoon balls and place them 3 inches apart.
Bake for 10-12 minutes, until the edges are golden and the centers look slightly underbaked. Press the reserved white chocolate chips into the warm tops and sprinkle with a pinch of flaky sea salt.Let the cookies cool on the sheet for 10 minutes before moving them to a wire rack.
