Melt butter and stir until light in color. Add sugar. Add almonds with the beaten eggs. Add flour and mix well. Let the dough cool.
Place the dough in the middle of a cookie sheet, then work it toward the edges with your thumbs to cover the whole cookie sheet as thinly as possible. Sprinkle with granulated sugar.
Bake in a moderate oven (preheated to 375 degrees) until golden brown. Cut into squares.
