Preheat the oven to 350 F and prepare a baking sheet with parchment paper and then set it aside. In a small bowl, stir together the flax meal and water and set it aside to gel for about 5-10 minutes.
Meanwhile, place your vegan butter, brown sugar and white cane sugar into a bowl of a stand alone mixer or into a mixing bowl and using a handheld mixer, beat until light and fluffy, about 2 minutes. Add in the vanilla extract and flax mixture and continue mixing until well blended.
In a separate bowl, whisk together the all purpose gluten free flour, baking soda and salt then add it to the mixing bowl. Mix just until combined and the dough comes together. Fold in the nuts and white chocolate. Use a 1 1/2 inch cookie scooper to make about 16 evenly sized cookies. Place them on the cookie sheet about 2 inches apart (mine fit 6 on the cookie sheet). Bake the cookies for 9-12 minutes and edges are golden brown.
Once you remove the cookies from the oven, if they have spread too much, use a round cookie cutter, fit the cookie inside and swirl it around in a circular motion. *See GIF in post. Top with more white chocolate chips, pressing them into the cracks, if desired. Repeat until you have baked all the dough.
