Step 1: For your white chocolate macadamia cookies, in a small bowl, combine flour, baking powder, baking soda and salt.

Step 2: In a large bowl or stand mixer, cream the butter, brown sugar and white sugar until light and fluffy. Add egg, egg yolk and vanilla paste and beat until combined.

Step 3: Add the flour mixture, whisking until just combined. Fold in white chocolate chunks and macadamia nuts. Chill the dough for 2 up to 24 hours.

Step 4: Preheat oven to 350°F (180°C).

Step 5: Scoop 2 tablespoon portions of dough, roll into a ball and slightly flatten with your hands. Place on two baking sheets lined with parchment paper, a couple of cm apart (they will spread).

Step 6: Bake for 12-14 Minutes until the edges are golden brown and the middle is still soft. Make sure not to overbake. Allow cookies to cool completely before transferring from the baking sheet.
