Whisk together the vegan butter, granulated sugar, and brown sugar in a large bowl until light and fluffy. Add plant-based milk and vanilla extract. Cream once again.
Take the cardamom pods and separate the pods from the shell. Grind them using a mortar and pestle and add that to the mix.
Combine the dry mixture (flour, cinnamon, baking soda, and salt) in another bowl and add that to the wet mix. Stir together with a wooden spoon until everything is combined.
Chill for 2-3 hours and then scoop out and roll the dough into desired size.
Make the cinnamon sugar coating by combining granulated sugar and cinnamon in a plate. Coat each ball in the cinnamon sugar.
Transfer cookie dough balls to a lined baking tray. Bake for 11-12 minutes or just until the edges start to firm up. Allow cookies to cool for 5 minutes on the baking sheet before enjoying.
Notes
Do not over-bake. Remove the cookies from the oven while they still seem underbaked. They will sort of deflate and firm up while cooling.
