Preheat the oven to 420° F. Make the flax eggs by mixing ground flax seeds and hot water into a small bowl.
In a medium size bowl, mix melted vegan butter, coconut sugar, flax eggs, vanilla, baking powder, coconut milk (or milk of your choice) and salt until fully combined.
Slowly add flour and mix until it forms into a dough.
Place parchment paper or silicone baking mat onto a baking sheet. Scoop dough 1 Tbsp at a time and form into cookie balls with your hands. Place each cookie ball spaced out onto the baking sheet.
Bake the cookies for 11 minutes until the cookies are slightly golden around the edges.
Allow cookies to cool on a baking sheet and making frosting in mean time.
