Preheat the oven to 350°F (175°C) and line the baking tray with parchment paper. Set aside.
To a medium-size mixing bowl, add vegan butter, white cane sugar, and brown sugar and mix with a hand mixer for about 1 minute until fluffy. Add unsweetened almond milk and mix until combine. Then add half of the all-purpose flour, cornstarch, baking soda, and a pinch of sea salt, mix, add the rest of the flour and mix again with a hand mixer or spatula until just combined. Be careful not to overmix the dough. Fold in chopped pistachios and vegan white chocolate.
Scoop out 10 dough balls (using medium size scoop – 2inch /5cm). Place the cookie dough ball on the prepared baking tray (make some space between them), top with more white chocolate chunks and chopped pistachios, and bake in a preheated oven for 11-12 minutes.
Take the cookies out of the oven and let them sit on the tray for about 2-3 minutes. Then transfer them to a cooling rack and let cool for about 10 minutes.
Enjoy!
