When I have a sweet tooth craving, I want something quick. Usually, it’s ice cream, or I’ll often do a yogurt parfait with honey and granola.

These 3 ingredient banana peanut butter cookies are perfect when you want a quick and healthy dessert or snack, and that’s that.

Or, a middle of the night breastfeeding snack. Keep a bunch on your nightstand!

We love no bake cookies. Really, any cookies.

While my powdered peanut butter cookies are addictive, these no bake pumpkin cookies are a year-round staple since they are no bake. With these 3 ingredient vegan peanut butter cookies, you definitely don’t have to bake them.

I mean, since these vegan oatmeal cookies use 3 ingredients (sans eggs), you technically could eat them as is. They’ll just be a little softer.

Speaking of vegan cookies, these vegan leftover oatmeal cookies are a great recipe using cooked oatmeal. 

However, I like them crisping up a bit with the oven and giving these 3 ingredient vegan cookies a little more structure – but that’s totally up to you!

They are exceptionally easy, and who wouldn’t want a recipe for 3 ingredient cookies with banana and peanut butter?!

What You Need For 3 Ingredient Vegan Peanut Butter Cookies

The three ingredients you’ll need for babies are:

• Peanut Butter – I recommend a drippy one, like my all-time favorite brand
• Bananas – The riper the better for a sweeter product and more ease with mashing
• Oats – Any type of oats will do! I would recommend quick cooking oats for the best result.

Because peanut butter and banana is a match made in heaven, we know these will be good. I also like to add some sea salt on top, as it makes a big difference in exaggerating the already delicious flavor.

I promise you, these vegan peanut butter cookies with just 3 ingredients will be your new method for simple meal prep for snacks during the week.

And then make sure to freeze some for later so future you will thank you, and they’re great for easy postpartum snacks. 

Healthy Banana Peanut Butter Cookies Nutrition Facts

You can already guess that these 3 ingredient cookies with banana and peanut butter are going to be amazing but they are also very nutritious, considering we’re using three wholesome ingredients.

• Each of these healthy no bake oatmeal cookies offers up 2 grams of fiber and nearly 3 grams of protein.
• Peanut butter offers healthy unsaturated fats
• Oats provide additional iron, beta glucan fiber, prebiotic fiber, B Vitamins and complex carbohydrates.
• Bananas offer potassium, B Vitamins, Vitamin C and antioxidants.

Because of this, they’re a great snack to pair with a fruit, or another protein rich snack (like jerky, hard boiled eggs, yogurt) for sustained energy.

I always recommend my clients pair up snacks to make them last longer and feel satisfied after eating.

How To Make Vegan Banana Peanut Butter Cookies

You’ll start by mashing your ripe bananas in a bowl, and then mixing with oats. It may feel a little thick, so having mushier (ie – riper) bananas helps. 

Then, mix in your peanut butter until the batter is smooth. You can taste as you go along – I always do. That’s why these remain the best 3 ingredient vegan peanut butter cookies.

At this point, if you wanted to enjoy them as vegan no bake cookies, you could just form them into a cookie shape and put in the fridge for a bit, and then eat!

I’ve done this if I’m in a rush, but I prefer the crispier nature that happens out of the oven.

Otherwise, line your baking pan with parchment paper and divide the batter into 12-15 scoops. If you like smaller cookies, you’ll get more, closer to 15. 

I tend to like my 3 ingredient vegan banana cookies smaller because I share them with my girls and I find that they are easier for traveling (great road trip food idea!).

But big ones may last a little longer in your house. There’s really no wrong way. 

Just bake, and there you have it, a fun and easier spin on my popular coconut flour oatmeal cookies. 

These 3 ingredient breakfast cookies make for a great healthy nursing snack for breastfeeding hunger or a healthy postpartum snack, too.

Since they have oats and peanut butter (both are lactogenic foods to increase milk supply), they are great for energy and satiety. 

Utilize that chest freezer or deep freezer if you can to make your future self happy!

How To Store 3 Ingredient Banana Oatmeal Cookies

These 3 ingredient banana oatmeal cookies are 100% best enjoyed out of the oven, sprinkled with a little sea salt.

However, if you want to save them for later, just stick them in a freezable ziplock bag (these are my favorite). Store for up to 2-3 months.

For reheating, you can eat them cold or at room temperature, but I actually prefer them straight out of the toaster oven, to get a little crisp.

I have several other no bake healthy snacks that I prefer to enjoy that way, too!

Helpful Tips

Lastly, here are some helpful tips for these bite-sized cookies.

• Use Ripe Bananas – The riper, the better. Riper bananas produce a sweeter end product, without adding any sugar at all. If you’re curious as to why this is the case, here’s some information about why ripe bananas are sweeter.
• Bake a little longer for crisper cookies – My cookies were done around 12 minutes. However, if I wanted them a little crispier, I would have left them for up to 13-14 minutes.
• Use creamy peanut butter – I’ve had the best success with creamy peanut butter. It spreads more easily and can mix more easily. If you are using a thicker peanut butter, using finer ground oats, like quick cooking oats, may help.
• Make 3 ingredient applesauce oatmeal cookies – Out of bananas or they aren’t ripe yet? You can substitute applesauce for bananas. The applesauce does give an apply flavor so if you’re not into that, it may not be best for you. Instead of the two bananas, use 1-2 to 3/4 cup applesauce and follow the same directions. I like to add 1-2 tablespoons of flax seeds if doing this.

Other optional add-in’s: Flax seeds, chia seeds, hemp seeds, nuts, chocolate chips, cocoa nibs, raisins, pumpkin, etc. The options are limitless.
