Serving Suggestions

These cookies are perfect for a quick breakfast on the go, an after-school snack, or a cozy treat with your afternoon coffee or tea. I also love packing one in a lunchbox or grabbing one straight from the freezer when I need something sweet and satisfying.

Tips for Success

  • I like to refrigerate the dough for 30-60 minutes before baking to help the flavors meld together. It also makes the dough a bit easier to handle, but this step is totally optional.
  • Use very ripe, medium-sized bananas for this recipe. They should have lots of browning on the peels, and the bananas themselves should have soft brown spots all over.
  • I prefer melted coconut oil to keep this recipe dairy-free and vegan-friendly. You can substitute with another neutral-flavored oil, such as vegetable oil or melted butter, for a non-dairy-free option.

Storage Instructions

I’ve found that these banana oatmeal cookies stay fresh for up to 2 days at room temperature in an airtight container. For longer storage, refrigerate them for up to a week—just know they may get a bit softer.

They also freeze well. Once cooled, place them in a freezer-safe bag or container and freeze for up to 3 months. Let them thaw at room temperature or warm them briefly in the microwave.

You can also make the dough ahead and refrigerate it for up to 2 days. Just keep it tightly wrapped and let it sit out for a few minutes before scooping and baking.
