This video introduces a simple icebox cookie recipe that uses mayonnaise instead of eggs and butter. The dough is made by mixing just three ingredients: mayonnaise, sugar, and all-purpose flour. The key to the dough's consistency is to add the flour in two batches instead of all at once to achieve the ideal consistency. In addition to plain, you can also make cocoa and matcha flavored dough. After shaping the dough, moisten the surface with water, sprinkle with granulated sugar, cut into 7mm thick slices, and bake in a preheated oven at 170°C for 12 minutes. The finished cookies have a crisp and crunchy texture, and you can barely taste the mayonnaise. The video also tests the difference in the finished product depending on the type of mayonnaise used (low-calorie or egg-free), and advises refrigerating for a day if you are concerned about the acidity. This is an easy and delicious icebox cookie recipe that even beginners can easily make.
