  • ¾ tsp baking soda
  • ½ cup walnuts chopped (optional)

  • Measure out the dry ingredients together in a small bowl, set aside.
  • Using a mixer, cream together the butter and sugar.
  • Add the egg and vanilla, mix again until creamy.

  • Drop by teaspoons onto a cookie sheet lined with parchment paper, bake for about 10 minutes. Remove from pan and allow them to cool on a baking rack.
  • For the frosting - When the cookies are done baking, make the brown butter. Brown slightly.

Tips to make brown butter
  • Although you may be tempted to use margarine, be sure to use real butter. That's where you get your butterscotch flavor! Plus that's what Grandma always said and she always knew what she was talking about! :)
  • Use a light-colored pan because as the butter goes from yellow to golden, to a toasty brown you'll be able to see the color change better.
  • The butter can go from golden brown to burnt in an instant - keep an eye on it and don't leave it unattended.
