Prepare two large sheet pans by spraying with cooking spray or lining them with parchment paper. Set aside.
Using a stand or hand mixer, beat together the salted butter and white sugar. Beat for 2-3 minutes to incorporate plenty of air. It should be light and fluffy.
½ cup salted butter, 1 cup granulated white sugar
Mix in the mashed ripe bananas, Greek yogurt, egg, and vanilla extract. Beat for 2-3 minutes again.
1 cup ripe bananas, ⅓ cup plain Greek yogurt, 1 egg, 1 teaspoon vanilla extract
In a separate bowl, combine the all-purpose flour, cinnamon, baking soda, baking powder, salt, and nutmeg. Stir well.
2 cups all-purpose flour, 1 teaspoon cinnamon, ½ teaspoon baking soda, ½ teaspoon baking powder, ½ teaspoon salt, ¼ teaspoon nutmeg
On low speed, add the flour mixture into the batter until just barely combined.
Fold in the chocolate chips.
1 cup semi-sweet chocolate chips
Use a cookie scooper to scoop two-inch balls of dough onto the sheet pan (I used a 2-inch cooking scoop for this step). Leave two inches between each cookie.
Bake cookies in the oven for 10-12 minutes or until cookies have puffed up and the edges are lightly golden. Plate and serve.
Notes
Storage:
To Store: After baking, store these at room temperature in an airtight container for up to one week.
To Freeze: You can freeze these cookies for up to 3 months in a freezer safe container. Let them thaw at room temperature when you are ready to eat them.
Tips:
You can add chopped nuts to the banana bread cookie batter for extra crunch and a boost of nutrition. I like using pecans or walnuts to make chocolate chip banana nut cookies because they have a sweet and toasty taste.
Instead of chocolate chips, feel free to mix some raisins, chopped dried fruit, nuts, or banana slices into the batter.
To make the very best banana bread cookies that are super moist, it is important to start with overripe bananas. They should be dark yellow with lots of browning. The riper the bananas, the more moist your bread will be and the more banana flavor it will have!
