Mix the non-dairy milk and vinegar and set aside.
In a bowl, mix the all purpose flour, baking soda, baking powder, and salt.
Preheat the oven to 375 degrees.
In a stand mixer or in a large bowl, place the softened butter or margarine or coconut oil and beat with the sugar until everything is soft and well-mixed.
Add the applesauce, vanilla extract, and cardamom powder and mix well.
Add the flour mixture in two batches, mixing with a spatula after each addition until everything is incorporated. Add the milk and mix. The dough should not be wet but moist enough to come together in a ball.
Using your fingers, pinch off a small portion of the dough and roll into a smooth ball. Flatten it slightly and place on an ungreased baking sheet. Leave at least an inch between the cookies because they will spread.
Bake in the preheated oven for 10 minutes or until the cookies are lightly brown.
Remove, and after two minutes, slide off the cookies with a spatula to a rack to let them cool.
