Add the buttery spread to the bowl of a stand mixer, beat on high speed for 1 minute, until the mixture begins to lighten.
Add 1 1/2 cups of the confectioners’ sugar. Beat for 2 minutes until smooth, light, and fluffy. Add the remaining confectioners’ sugar, milk, and the vanilla extract. Beat for an additional minute until smooth and creamy, adding a teaspoon of milk at a time if needed. Stir in the Mini Chips.
Spoon into a container to serve alongside the Mini Cookies for a dunkable snack.
