Chocolate Chip Banana Cookies

Ingredients

• 1/2 cup walnuts (optional)
• 1 cup all-purpose flour
• 1/2 cup whole wheat flour
• 1 teaspoon kosher salt
• 1/2 teaspoon baking soda
• 3/4 cup unsalted butter, room temperature
• 1/2 cup packed light brown sugar
• 1/2 cup white sugar
• 1 large egg
• 1 1/2 teaspoons vanilla extract
• 1/2 cup mashed very ripe banana
• 1 cup old-fashioned rolled oats
• 8 ounces semisweet chocolate chips

Directions

Preheat oven to 350 degrees F (175 degrees C). Line baking sheets with parchment paper.

Spread walnuts onto a baking sheet.

Bake in the preheated oven until walnuts are toasted and fragrant, 5 to 7 minutes. Remove from oven and cool; coarsely chop.

Whisk all-purpose flour, whole wheat flour, salt, and baking soda together in a bowl. Beat butter, brown sugar, and white sugar together in a bowl using an electric mixer until pale and fluffy; add egg and vanilla extract. Beat until just combined. Beat banana into creamed butter mixture until just combined.

Stir flour mixture into creamed butter mixture until dough is just combined; fold in oats, chocolate chips, and walnuts. Drop heaping spoonfuls of dough onto the prepared baking sheets, spacing each mound about 1 1/2 inch apart.

Bake on the center rack of the preheated oven for 6 minutes. Rotate pans and bake until edges are browned, 6 to 7 more minutes. Cool cookies on the baking sheets for 5 minutes before transferring to wire racks to cool completely.
