In a mixer, beat the butter and Peter Pan Simply Ground™ on medium speed until well blended, then slowly add the milk. Gradually add the powdered sugar until icing reaches the desired consistency. I used 1 1/4 Cups to get a relatively stiff icing.
Spread about 1/2 teaspoon of icing onto a NILLA Wafer and sprinkle on mini chocolate chips. Top with a second NILLA Wafer. Gently squeeze the NILLA Wafers together, then add more mini chocolate chips to the edges , if desired.
Serve with hot cocoa, if desired.
