This fudgy frosting is perfect for dipping or spreading over cookies for a chocolaty delicious finish that is stackable. Your cookie trays just got an upgrade!
In a double boiler melt chocolate chips, butter and milk stirring frequently until the mixture is melted.
Whisk in the powdered sugar until completely incorporated and smooth.
While keeping the frosting warm, spread over cookies. Add sprinkles if desired and place on wax paper in a single layer until completely set. Then stack and store in airtight containers.
