In a sauce pot brown the butter, take off the heat and allow to cool a little.
Preheat the oven to 180℃, line a baking tray with parchment paper and set aside.
In a large mixing bowl add the browned butter, brown sugar, white sugar, almond extract, vanilla extract and stir the mixture together vigorously until combined and smooth. Add the egg and beat again until combined.
Add the flour, corn flour, baking powder, baking soda, salt, salted roasted chopped cashew nuts, caramelized white chocolate and stir until combined - make sure there are no dry flour pockets.
Scoop the dough, flatten it out between your palms and place onto a baking tray leaving space between each ball and bake for 9-10 mins, they will still be soft if you press them but that is fine - they will finish cooking in the residual heat outside the oven.
Using a flat metal spatula transfer them to a wire rack to finish cooling before serving.
Top each warm cookie with a chocolate chunk and hit them with flakey sea salt while still warm.
