If you would like to make this vegan fudge in a microwave instead of on the stove, add the chocolate chips to a large microwave safe bowl. Pour the vegan sweetened condensed milk over the chips. Microwave for 60 seconds, then stir the mixture. Microwave for 60 more seconds and stir again. Continue to microwave at 30 second intervals until the chocolate has completely melted and combined with the milk.
