No, most actually aren't. Make sure you read the back of your chocolate chip package to know whether it's vegan or not. You will typically see milk fat as an ingredient that isn't vegan. My favorite vegan chocolate chips are either the enjoy life brand, trader Joe's semi-sweet, or occasionally Costco will carry them in a Kirkland brand white bag. If you're looking for more of a milk chocolate flavor, go with the enjoy-life chocolate chips. Most other brands will be more of a dark chocolate chip.
