Line an 8" square or rectangle baking dish with waxed paper, allowing the paper to extend beyond two opposite ends.
Place chocolate chips in a microwave-safe bowl. Add the vegan sweetened condensed milk. Stir to make sure the chocolate chips are coated. Heat for one minute in the microwave. Remove from the microwave and place a lid over the bowl for one minute, to allow the chocolate to melt. Stir until creamy.
Add the chopped nuts and vanilla and stir to combine.
Pour the fudge batter into the prepared baking dish. Cover and chill for 1 to 2 hours until the chocolate is set.
Once set, lift the fudge by the waxed paper out of the dish. Remove the waxed paper from the chocolate and cut it into square pieces.
This fudge will stay fresh on the counter for up to a week if you keep it covered.It will last longer in the fridge, up to 2 to 3 weeks. And you can even freeze it for up to 2 to 3 months.You want the fudge to be nice and tall which means using a smaller pan.
