1 1/2 cups old fashioned oats
3 tablespoons unsalted butter
1 medium ripe banana, mashed
3/4 cup packed brown sugar
1/2 cup granulated sugar
1/2 cup cashew butter
1 teaspoon vanilla extract
1 large egg
1/2 cup unbleached all purpose flour
1/2 cup whole wheat flour
3/4 teaspoon baking soda
1/4 teaspoon salt
1 cup semi-sweet chocolate chips
Cook oats in a small saucepan, over medium heat, for 3-4 minutes, stirring frequently, until fragrant and light golden brown.
Melt butter in a small saucepan over medium heat; cook 2-3 minutes, whisking frequently, until butter browns and starts to foam. Remove pan from heat and set aside.
Add melted browned butter, banana, brown sugar, granulated sugar and cashew butter to a large mixing bowl. Beat ingredients together, using a mixer on medium speed, until well incorporated - about 1-2 minutes. Beat in vanilla and egg until combined - about 1 minute. Reduce mixer speed to low and beat in oats, all purpose flour, whole wheat flour, baking soda and salt until combined. Stir in chocolate chips until combined.
Chill dough in refrigerator for 30 minutes.
Preheat oven to 350 degrees F. Coat cookie sheets with nonstick cooking spray.
Drop rounded tablespoons of dough onto cookie sheets, about an inch apart. Bake 10-12 minutes or until light golden brown around edges; cool 1 minute before transferring cookies to wire racks to cool completely.
