To prepare a vegan chocolate truffles recipe, first you need to prepare your ingredients. First, you'll need your chocolate. You can buy chocolate at your local grocery store, or you can make your own at home. Using your food processor, pulse the chocolate until it's finely ground. Then, add in your vanilla extract, and mix until the ingredients are evenly combined. Next, pour the mixture into your ice cream maker and pulse it until you get the consistency of coarse crumbs.
