Simple to customise, soft and chewy Banana Blueberry Oatmeal Cookies are amazing! The toasty cinnamon, sweet banana, and tart blueberries with oats are delicious.
Start with a large parchment-lined baking sheet and a 350°F oven.Smash the bananas in a large bowl until creamy (you can leave them bumpy, but aim to homogenous).
