These cookies from Uruguay are called yo-yo as they actually look exactly like the toy yo-yo. When I took them to my colleagues as my first batch of test eaters, they got raving reviews. According to a few colleagues, I should bring more often treats from Uruguay if they were as tasty as these cookies. What I like about them is the fact that you can easily mix together the batter fairly quickly. It does contain a small part of cornstarch that makes them extra soft. Obviously it does contain the caramel cream names dulce de leche and is covered in chocolate. This is my sixth recipe in my cookie week.
