  • oven


  • 2 cups all-purpose flour
  • 2 teaspoons cornstarch
  • 1/2 teaspoon baking powder
  • pinch salt
  • 3/4 cup Duke's Mayonnaise
  • 1/2 cup granulated sugar
  • 1/2 cup firmly packed light brown sugar
  • 1 large egg
  • 2 teaspoons vanilla
  • 1 cup bittersweet or dark chocolate chips
  • 1/2 cup butterscotch chips


  • Preheat oven to 350 degrees. Line two rimmed baking sheets with parchment paper.
  • Stir together flour, cornstarch, baking soda and salt in small bowl.
  • In a medium bowl, whisk together mayonnaise, sugars, egg and vanilla until mixture is smooth. Add the flour mixture and stir until combined. Fold in chocolate and butterscotch chips.
  • Using a small cookie scoop, scoop the dough into 24 balls or roll into 24 (1 ½ inch) balls. Place dough balls 2 inches apart on prepared baking sheets.
  • Bake at 350 for 12 – 14 minutes, until bottoms and edges of cookies are lightly golden. Let cool on baking sheets for 5 minutes before removing to wire racks to cool completely.
  • Store cookies in an air tight container.


To measure the flour, spoon it into your measuring cup and level it off with the flat edge of a knife. Don’t shake or scoop directly from the flour bag which will lead to too much flour in your cookies.
