  • Stand Mixer


  • 2 Cups All Purpose Flour
  • 2 ½ Cups Oat Flour See Note Below
  • 1 teaspoon Baking Soda
  • 1 teaspoon Baking Powder
  • ½ teaspoon Salt
  • 1 Cup Unsalted Butter Room Temperature
  • 1 cup Granulated Sugar
  • 1 cup Brown Sugar
  • 2 Eggs Room Temperature
  • 1 teaspoon Vanilla
  • 12 Ounces Chocolate Chips
  • 4 Hershey Bars 1.55 ounces each
  • 1 ½ cups Chopped Walnuts Optional


  • Preheat the oven to 375°. Line a baking sheet with parchment paper or a silicone mat. Set that aside.
  • Mix together the oat flour, all purpose flour, baking powder, baking soda, and salt. Set that aside.
  • In the bowl of a stand mixer fitted with a paddle attachment, beat the butter, brown sugar, and granulated sugar together for 1-2 minutes on medium speed. The mixture should be completely combined.
  • Add one egg at a time, mixing well between each addition. When both the eggs are added, add in the vanilla extract and mix to combine.
  • With the mixer on low, add the dry ingredients to the wet ingredients. Mix until just combined, scraping down the bowl as necessary to make sure all the dry ingredients are completely combined.
  • Chop the Hershey bars into rough pieces and add them to the bowl. Add the chocolate chips and walnuts (if using). Mix until everything is just combined.
  • With an ice cream scoop, scoop the cookie dough onto the baking sheet, leaving about an inch between each cookie.
  • Bake for 10-12 minutes and then cool them on a wire rack until completely cooled. Continue baking them until all the batter is done. Yields 4 Dozen cookies.
