Instructions

  1. Preheat oven to 350°F Lightly grease 2 baking sheets.
  2. Beat the butter, oil sugars, vanilla, salt and instant coffee in a large bowl until smooth.
  3. Beat in the vinegar, egg, baking soda and baking powder until well combined.
  4. Stir in the flours until well combined.
  5. Stir in the chocolate chips, toffee bits and pecans, if desired. *The dough wil appear oily.
  6. Scoop out 1 inch balls and place on baking sheets. They don't need to be spaced far apart because they don't spread much. *I tried flattening some but didn't like them as much.
  7. Bake 14-16 minutes, reversing trays half way through, until golden brown all over with no hint of softness in the center.
  8. Remove from oven and allow cookies to cool 5 minutes on baking sheets before transferring to racks or paper bags to cool completely.
