Peel the bananas and add them to a large bowl. Use a fork to mash the bananas.
Add the peanut butter, vanilla extract, and sugar and stir them to combine.
Add the oats and stir till fully combined. Then, stir in the chocolate chips.
Use a cookie scoop or large spoon to scoop golf ball sized rounds onto a parchment-lined cookie sheet.
Bake for 15 to 17 minutes until the cookies are golden brown.
Remove the cookies from the oven and allow them to cool for a few minutes before serving.
Notes
Storage - save cookies at room temperature in an airtight container for 2-3 days, in the refrigerator for up to 7 days, or freeze them for up to 2-3 months. Baking Tips - Line your cookie sheet with parchment paper or aluminum foil. This keeps the cookies from sticking to the pan and makes clean-up easier!Crispiness - If you like a crispier cookie, you can flatten the cookie dough balls with your hands before baking and add 2 minutes to the baking time. I enjoy a softer cookie (which these are), so only bake mine for 15 minutes. They need a few minutes to cool and set up before eating.Equipment - Because this cookie recipe makes 15 to 16 cookies, you'll likely need to use two sheet pans/cookie sheets to bake all the cookies. I used a full-sized, rimmed baking sheet and a half-sized rimmed baking sheet.
