Eating this cookie will remind you of a favorite childhood snack enjoyed with a tall glass of cold milk. Great with fruit, and with chocolate and caramel ice creams.
Sift together flour, cinnamon, baking soda, and salt. In a separate bowl, cream butter and brown sugar. Add egg and egg yolk, one at a time, then vanilla. Add flour mixture, incorporating thoroughly. Stir in almonds. Shape the soft dough into 4 logs about 7 inches long. Wrap in plastic and refrigerate until firm.
Adjust rack to lower third of oven and preheat oven to 350 degrees F. Slice each log into ⅛-inch-thick rounds, and place 1 inch apart onto parchment-lined baking sheets. Bake for 8 to 10 minutes, or until cookies are set and light tan on the bottom. Cool on a wire rack.
