Instructions
Preheat oven to 350 degrees. Line an 8-inch square pan with parchment and grease generously with butter. This is for flavor.
Cut the stick of butter into chunks, put it in a saucepan and melt it over medium heat, swirling often, just until it starts to form browned bits. Remove from heat and let cool.
In a large mixing bowl, whisk together browned butter and sugar, then whisk in egg and vanilla, followed by mashed banana.
Stir together flour, baking soda and salt.
Add flour mixture and oats to mixing bowl and stir until halfway blended. If your mixture is warm let it cool slightly, then stir in chocolate chips and nuts.
Spread batter in prepared pan and bake for about 28 minutes or until golden brown. Let cool completely. Lift from pan and cut into squares.
