In a bowl, mix the flour, sugar, eggs, milk, and butter. Whisk everything together, first with a fork, until you get a smooth dough. Lightly flour a flat surface (a table, for example) and knead the dough by hand until it no longer sticks to your fingers. Roll out the dough using a rolling pin (or a clean glass bottle). Once it has reached the desired thickness, cut it into rounds or squares with a knife. You can also use cookie cutters to create shapes.
Lightly grease a baking sheet with butter and arrange the cookies on it. Bake them in the oven for about 10 to 15 minutes at 180 degrees Celsius (350 degrees Fahrenheit).
