Total Time45 mins
Servings: 2 dozen cookies


  • Cookies:
  • 1/2 cup 1 stick unsalted butter, softened
  • 1/2 cup brown sugar packed
  • 1/4 cup sugar
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • 3 medium mashed bananas about 1 1/2 cups
  • 2 eggs
  • 1 3/4 cups all purpose flour
  • 1/2 cups old fashion oats
  • 1 teaspoon baking soda

Brown Butter Frosting:

  • 1/3 cup butter
  • 3 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 3-4 tablespoons milk


  • Preheat oven to 350 degrees F. Line two baking sheets with parchment paper or silat; set aside.
  • For the cookies: Using your stand or hand mixer, mix together the butter, sugars and salt until light and fluffy. Add in the vanilla and bananas.
  • Mix in the eggs, one at a time, making sure that each egg is incorporated before adding the next.
  • Whisk together the flour, oats and baking soda, then with the mixer on slowly add until everything is combined. Ladle the sides and bottom of the bowl.
  • Scoop roughly 2 tablespoons on prepared baking sheet. Bake 12 to 14 minutes, or until tops spring back and edges are lightly golden brown. Let sit on the baking sheet for 5-10 minutes then transfer to a cooling rack.
  • Let cookies cool completely before frosting.
  • For the Frosting: Using a small saucepan, add butter over medium heat. Brown butter, making sure to stir constantly for about 3- 5 minutes. Make sure you watch your butter because it can go from golden brown to burnt in seconds. Let cool 5 minutes before making the frosting.
  • Add the powdered sugar, browned butter and vanilla extract to a bowl. Whisking together, add 1-2 tablespoons of milk, until frosting is smooth and creamy. You want the frosting to be thick. If you need to add more milk, add until desired constancy.
  • Spread frosting on top of cookies and let sit 10 minutes, so the frosting can harden.
  • Serve and enjoy!
