In a large bowl using a hand-held mixer or stand mixer fitted with a paddle attachment, cream the butter, Nutella, and brown sugar for 2 minutes until light and fluffy.
Add the flour, vanilla, and salt. Slowly beat in milk to thin to desired consistency.
Fold in the chocolate chips. Chill for at least 30 minutes. Sprinkle with more chocolate chips when ready to serve if desired.
