  • Reynolds Kitchens® Parchment Paper with SmartGrid®
  • 2 cups flour
  • 3 cups old fashioned rolled oats
  • 1 ½ teaspoons cinnamon
  • ¾ teaspoon baking soda
  • ½ teaspoon salt
  • pinch of nutmeg
  • 1 cup salted butter softened
  • ¾ cup packed brown sugar
  • ½ cup sugar
  • 3 medium bananas mashed, about 1 cup
  • 1 teaspoon vanilla
  • 2 large eggs
  • 2 cups semi-sweet chocolate chunks
  • cup chopped walnuts


  • Preheat oven to 350 degrees. Line a baking sheet with Reynolds Kitchens® Parchment Paper with SmartGrid®.
  • In a medium bowl whisk together flour, oats, cinnamon, baking soda, salt, and nutmeg. Set aside.
  • In a large bowl, cream together butter and sugars for 2-3 minutes until light and fluffy.
  • Add mashed bananas, vanilla, and eggs and mix until completely combined.
  • Add dry ingredients to wet ingredients and mix until combined.
  • Stir in chocolate chunks and walnuts.
  • Use an ice cream scoop to scoop dollops of cookie dough onto the prepared baking sheet being sure to use the gridlines to space the cookies at least 2 inches apart.
  • Bake for 10-12 minutes until browned around the bottom edges. Allow to cool on the baking sheet for 3-4 minutes before transferring to a cooling rack and repeating with remaining cookie dough.
  • Store in an airtight container up to 3 days or in the fridge up to 1 week.


Pro tip: to make your cookies look as amazing as they taste, reserve a handful of chocolate pieces and walnuts to add to the tops of the cookie dough mounds just before baking.
