Step 1

Preheat the oven to 375°F and prepare a cookie sheet with parchment paper or a silicone mat.

Step 2

Put the butter and applesauce in a stand mixer or large mixing bowl. Beat on medium speed until mixed together. Don't worry if it looks curdled, it will smooth out as you add additional ingredients.

Step 3

Add the sugar, bananas, vanilla, and eggs and continue to beat at medium speed. Next, add the flour, baking soda, salt, and cinnamon and continue beating until just combined.

Step 4

Stir in the oats, chocolate chips, and nuts with a spoon or spatula.

Step 5

Drop the dough onto the prepared baking sheet with a cookie scoop or spoon. These will rise and spread so give each one some room.

Step 6

Bake for 10 to 14 minutes or until golden brown around the edges. Transfer to a wire rack to cool.
