Preheat oven to 325 degrees.

In a large bowl, cream sugars with butter, egg yolk, and vanilla. Beat thoroughly. Stir in sifted flour and salt.

Spread on an ungreased 10x15x1-inch jelly roll pan. Bake for 20-25 minutes or until lightly browned.

While still hot, spread with chocolate chips and sprinkle with chopped almonds. When cool, cut into squares.
