In a small bowl, cream margarine and sugar together with a fork. Gradually add the soy milk and vanilla extract and mix well.
In a larger bowl, mix all the dry ingredients together well. Add as many chocolate chips as you like. I like my cookies very chocolatey, so I use about 2 cups of chocolate chips.
Pour the wet ingredients into the dry ones and mix until just combined.
Drop by tablespoonfuls onto a parchment-lined baking sheet, or use an ice cream scoop, to make about 2 dozen cookies (feel free to save some cookie dough raw in the fridge or freezer too).
Bake at 400F for 10-15 minutes, until golden brown, then cool on a wire rack. These freeze very well, and reheat nicely with 10-15 seconds in the microwave. Sooooo good!!!
