Since the 1930's milka and cookies have been a staple dessert combo in American cuisine and other countries. From oatmeal cookies to plain chocolate chips. With the milk people would dip their cookies in the beverage. This is not only makes the cookies more moist but also elevates both the milk and the (sometimes dry cookie). It's absolutely delicious and is enjoyed by little kids and adults. There's things like Oreo cookies and other things like Nutter Butters. The combo of these two is absolutely mouth watering and is sure to satisfy the cravings of any sweet tooth. So why is it a dip? The milk acts like the dip with the cookie being the chips. Apart from cookies you can also dip things like pizza and cereal. Another thing to dip is Chinese donuts in condensed milk (a thicker milk that is sweet).
