3 Ingredients for Peanut Butter Banana Cookies

The three ingredients you’ll need for these 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. I like to get mine from Thrive Market and load up.

Since the bananas add a natural sweetness, these cookies have no added sugars and hence, can be a great peanut butter recipe for baby.

Minimal ingredient recipes are the best! This and my pomegranate chocolate bark are two of my favorites.

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, flourless peanut butter banana cookies will be your new method for simple meal prep for snacks during the week.

HOT TIP

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


Nutrition Facts

Here’s a little bit more about the nutrition content of 3 ingredient cookies with banana and peanut butter.

  • Each of these healthy vegan peanut butter cookies offers up 2 grams of fiber and nearly 3 grams of protein.
  • Peanut butter offers healthy unsaturated fats and plant protein.
  • 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. That’s why these are the best 3 ingredient peanut butter cookies – no raw egg!

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 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.

These 3 ingredient breakfast cookies make for a great healthy nursing snack to quench that pesky breastfeeding hunger.

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!

Helpful Tips and FAQ

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.
  • How to store – If you want to save your 3 ingredient banana oatmeal cookies 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.

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