  • 0.33 cup very ripe banana purée

Instructions 

  • Cook the butter until deeply golden and nutty, then cool for 15 minutes.
  • Mix browned butter with sugars, then add egg, yolk, banana purée, and vanilla.
  • Combine dry ingredients and fold into wet mixture, then stir in oats and chocolate chips.
  • Chill dough for at least 4 hours, then scoop onto a baking sheet and bake at 350°F (175°C) for 11–13 minutes.
