In a bowl, add the ingredients oil through salt. Mix well until well combined and you don't see big drops of oil floating around.
Add 2.5 tbsp flour and sprinkle baking soda on the flour and mix well. Add a tsp flour at a time to make a thick batter mixture. Usually 3 Tbsp works out perfectly. Depending on the measurement of the wet ingredients, you might need a tsp less or more. The mixture should be thick batter, or stiff batter.
Fold in the chocolate chunks. Drop mixture on parchment lined baking sheet and flatten slightly. Sprinkle salt on the cookie and press in.
Bake at 350 deg F / 180ºc for 11 to 13 minutes till the edges just about start to turn golden. Tap the baking sheet and let it cool. The cookies will be soft right out of the oven, but will cool to be fudgy within 5-10 mins. Cool completely before storing.
Notes
I have made these cookies by subbing the 1 tsp maple + 1 tsp orange juice, with 2 tsp orange juice, 1 tsp aquafaba + 1 tsp maple, 1 tsp non dairy milk + 1 tsp maple. 2 tsp maple, 1 tsp maple + 1 tsp oil (in addition to the 1 Tbsp). These subs all work well. The best combination that works for me in terms of chewyness and flavor is orange juice + maple or oil + maple.If using a toaster oven, bake at a lower temperature (325 or 330 deg F).If the cookies come out too oily, evaluate the consistency of your batter like dough before baking. If it is too oily and liquid, Use 2.5 tsp oil or use more flour.
