Preheat your oven to 350* F. Line a baking sheet with parchment paper.
In a large bowl using a hand mixer, or in the bowl of a stand mixer fitted with the paddle attachment, cream the vegan butter and brown sugar until well combined and fluffy.
8 tablespoon Vegan Butter, room temperature, 1 Cup Brown Sugar, tightly packed
Add the non-dairy milk and vanilla and mix until well combined. The mixture will look broken here, and that's okay.
¼ Cup Non-Dairy Milk, 2 teaspoon Vanilla Extract
Add the flour, baking soda and salt and mix on low until just combined. Then add the chocolate chips and mix to distribute.
1 ¾ Cup All-Purpose Flour, ½ teaspoon Baking Soda, ¼ teaspoon Kosher Salt, 1 Cup Vegan Chocolate Chips
Use a 3-tablespoon cookie scoop to scoop cookie dough balls onto a prepared baking sheet. Be sure to leave at least 2 ½ inches of space between each cookie. I like to bake 6 at a time. Top each cookie with a few extra chocolate chips if desired, then a sprinkle of flaky sea salt. (See note!)
Flaky Salt for Topping
Bake in a 350* F oven for 13-15 minutes, turning halfway through baking. The cookies are done when they are golden around the edges. Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a cooling rack to continue cooling.
Repeat with the remaining cookie dough.
