1/4 c  Unsalted butter,softened

    1/3 c  Firmly packed light brown

           Sugar
      1 lg Egg yolks plus 2 tsp water

           Or 1 large egg white
    1/2 c  All-purpose flour

    1/4 ts Double-acting baking powder

    1/4 ts Salt

    1/4 ts Vanilla

      1 c  Semisweet chocolate chips

    1/2 c  Toasted rice cereal

   Preheat the oven to 375 F. In a bowl with an electric mixer cream the
  butter with the brown sugar until the mixture is light and fluffy and beat
  in the egg yolk mixture or the egg white. Add the flour, the baking powder,
  the salt, and the vanilla, stirring until the dough is blended well, and
  stir in the chips and the cereal. Arrange level tablespoons of the dough 2

  middle of the oven for 8-10 minutes, or until they are golden brown.
  Transfer the cookies with a spatula to a rack and let them cool.
