Once the cookies are cool, make the frosting by first melting the white chocolate chips in the microwave. Microwave for a total of 1 minute, stirring at the 30-second mark and at the 1-minute mark. In either a stand mixer cream together the butter, sugars, and vanilla. Once combined, add in the melted white chocolate. Mix well. Next, add the heat-treated flour and salt. Mix until well combined. Add in the powdered sugar, mixing slowly until the powdered sugar has been fully incorporated. Slowly add in a little bit of milk at a time while mixing until your frosting has reached your desired consistency.
Frost the cooled cookies and top with a few edible cookie dough bites and some mini chocolate chips. Chill the cookies in the fridge until ready to serve, best served chilled.
