Add chocolate chips to a large microwave-safe bowl. Microwave at 30 second intervals stirring in between until the chocolate is melted ~2 minutes total.
While the chocolate is warming, line a 6-8 cup loaf pan (~9"x5") with parchment paper.
Add the condensed milk, salt, and vanilla extract to the melted chocolate. Mix well to incorporate. The mixture will thicken.
Pour the chocolate mixture into the prepared pan and smooth the top.
Sprinkle toppings to the surface of the fudge and gently press them into down. Cover the fudge and chill for 1-2 hours or until firm.
Use a sharp knife to cut the fudge into bite-size squares. Stored in an air-tight container in refrigerator it will keep for 1-2 weeks.
