In a stand mixer, or using an electric mixer, beat the oil and sugar together, on medium-low speed until creamy and well combined. Add the flax eggs and vanilla bean paste and mix for another few seconds.
Whisk together the flour, baking soda, baking powder and salt in a separate bowl. Add it to the batter and mix on low speed until combined.
Stir the chocolate chips in by hand, cover the bowl and place in the fridge for at least 25 minutes.
Preheat the oven to 375 degrees and line a baking sheet with parchment paper.
Drop cold batter by tablespoons onto the parchment-lined baking sheet, about 1.5 inches apart from one another. Gently push down on the tops to flatten just a tad. Sprinkle each cookie with some sea salt flakes.
Bake for 15 minutes until the edges of the cookies are just beginning to turn brown. Allow to cool on the bakin sheet for a 5 minutes and then transfer to a wire rack to cool completely.
