These Banana Oatmeal Cookies are perfect if you’re looking for something a little different than the standard oatmeal raisin cookies. They are full of oats, banana, chocolate chips, and walnuts. I’ve been on a bit of a banana and chocolate chip fixation lately. Maybe you remember my Chocolate Chip Banana Bread recently? 

So much goodness in these cookies, I wasn’t sure what to call them… Banana Oatmeal Chocolate Chip Cookies, Banana Chocolate Chip Walnut Oat Cookies, Loaded Oatmeal Cookies? Well whatever you want to call them, they are delicious.

I love banana in my cookies BUT just like pumpkin, cookies with fresh ripe bananas can be overly soft and soggy like. I hate that!

I actually attempted these cookies a few times. One time did come out too soft and soggy, and another time the cookies came out extremely flat and kind of like florentines. Both were good in their own right but just wasn’t what I was going for.

There isn’t a HUGE amount of banana in these cookies. Just enough to get a little banana flavor without changing the consistency too much of the cookies. I actually based them a bit on my favorite and Best Chocolate Chip Cookie recipe.

How to Make Banana Oatmeal Cookies?

To start these Banana Oatmeal Cookies with Chocolate Chips and Walnuts, preheat your oven. Line a couple of baking sheets with parchment paper sheets.

Next mix the dry ingredients in a large bowl including the flour cornstarch, salt, baking powder, and baking soda.

In another large bowl beat together the butter, brown sugar, and granulated sugar until light and fluffy. Beat in the egg, then the vanilla and mashed banana.

Make sure your banana is very ripe and soft. Mash it with the back of a fork until it’s mushy. You could also use banana baby food if you want. There’s not A LOT of banana in these cookies but it does give the cookies a nice subtle banana flavor. If you add more banana the consistency of the cookies will change. You could also add a little banana extract for a stronger banana flavor.

Beat the dry ingredients into the butter and sugar mixture until just combined, then stir in the oats, chocolate chips, and walnuts.

I toasted my walnuts first to give them a little more flavor, but you don’t have to do that. You could also substitute your favorite nut such as pecans or peanuts.

Be sure to use old-fashioned oats. If you substitute other types of oats,  your results may vary.

You can make these cookies into any size you want, but I used a medium cookie scoop (about 1 1/2 tablespoons) which resulted in 2 dozen cookies.

Scoop the cookies onto a baking sheet that has been lined with parchment paper. These cookies do not spread or flatten much so you can flatten them slightly with your hand.

Then bake the cookies about 10-14 minutes or until golden brown around the edges. Let them cool slightly, then place them on cooling racks to cool completely. Or eat them warm when the chocolate chips are ooey and gooey, yum!

If you do want to make larger or smaller cookies, be sure to adjust the baking time.

Be sure to rotate the pans halfway through the baking time so they bake evenly.

Instead of chocolate chips and/or walnuts, you can add your favorite mix-ins such as other baking chips, chopped candy, nuts, raisins, or anything else you can think of!

Hope you enjoy these Banana Oatmeal Cookies with Chocolate Chips and Walnuts!
