Preheat the oven.For softer, chewier cookies with lighter color → 350°F (175°C).For crispier edges and deeper golden color → 375°F (190°C). Cream the margarine and sugar. In a mixing bowl, beat vegan margarine and brown sugar until smooth and fluffy.
Add wet ingredients. Stir in plant-based milk and vanilla until fully combined.
Mix dry ingredients separately. In another bowl, whisk together flour, baking soda, baking powder, and salt.
Bring it all together. Add the dry mixture to the wet in two batches, stirring just until dough forms.
Fold in chocolate chips. Don’t be shy here — a generous handful makes all the difference.
Scoop and shape. Use 1–2 tbsp of dough per cookie. Roll into balls and place on a baking sheet lined with parchment.
Bake. Bake 9–11 minutes (shorter if using a dark baking sheet, longer if using a light one). The centers should look slightly underbaked — they’ll firm up as they cool.
Cool briefly, then enjoy. Let them rest on the sheet for 2–3 minutes before transferring to a rack.
