First, make your flax eggs by combining flaxseed meal and water together; stir, then wait a few minutes, giving the flax time to absorb the water.
Next, combine cane sugar and brown sugar in a bowl, and then pour melted butter over top. Whisk butter and sugar together for one minute consistently.
Add your flax eggs and vanilla extract to the bowl and stir to combine; set bowl aside.
In a separate bowl, combine flour, baking soda and salt, then stir wet ingredients into dry ingredients with a wooden spoon.
Last, add walnuts and chocolate chunks.
Use an ice cream scooper to scoop dough onto a baking sheet; bake cookies for 10-12 minutes. You want the edges to be set but the centers to still be soft.
Allow cookies to sit on the baking sheet for 2 minutes before carefully transferring them onto a cooling rack.
