For the Cookies

  • 3/4 cup butter

  • In a large mixing bowl, cream the butter and brown sugar
  • Add the bananas, egg and vanilla extract, and beat with an electric mixer until combined 
  • Add the baking soda, cinnamon and sea salt, and gradually mix in the flour. Dough is sticky, but this is normal

For the Frosting

  • In a medium saucepan, heat the butter, heavy cream and brown sugar until boiling
  • Remove from heat, add the vanilla, and gradually stir in the powdered sugar until frosting thickens. Allow frosting to cool and thicken more for a few minutes until it reaches spreading consistency
  • Use a spoon to drop frosting onto cookies and gently spread over cookies. Frosting will set more as it cools. Store in refrigerator or a cool place

Dough is sticky like banana bread batter. You can use a spoon to drop batter onto cookie sheets or use a piping bag or zip top plastic baggie to pipe batter onto cookie sheets.
Allow frosting to cool down slightly for a few minutes before using. It's thin, but thickens and firms up as it cools.
