Cream together butter and sugar. Add maple syrup and maple flavoring and beat until fluffy. Add eggs one at a time, beating after each addition. Sift together salt and cake flour and add to cookie mixture. When blended, stir in milk chocolate toffee chips.
Divide dough into 4 pieces and shape each piece into a roll. Wrap each roll in plastic wrap and refrigerate at least six hours.
Preheat oven to 350 degrees F. Cut dough rolls into 1/4 inch slices and place on cookie sheets lined with parchment paper. Bake 10-12 minutes or until they just begin to turn golden brown. Yield: 5 dozen.
