I mean, since these vegan oatmeal cookies use 3 ingredients (sans eggs), you technically could eat them as is, without baking.

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

Why You’ll Love 3 Ingredient Vegan Peanut Butter Cookies

• Dietitian tested and approved – As a Registered Dietitian, I’ve made and tested these cookies several times to get the best outcome for you while keeping them low in sugar. Each of my three children have also approved of these banana peanut butter oatmeal cookies because they are sweet enough without adding more sweetness.
• Fit nearly any dietary pattern – These 3 ingredient cookies with banana and peanut butter are gluten-free, vegan, vegetarian, dairy-free, etc.
• Only 3 ingredients – Need I say more? Vegan banana peanut butter cookies are quick and easy, with no added sugars.
• Budget Friendly – The 3 ingredients you need are pantry staples – I bet you already have them on hand!
• Healthy – Each of these healthy peanut butter banana oatmeal cookies offers up 2 grams of fiber and nearly 3 grams of protein. Oats provide additional iron, beta glucan fiber, prebiotic fiber, B Vitamins and complex carbohydrates. Bananas offer potassium, B Vitamins, Vitamin C and antioxidants.
• Great for dessert – If you like healthy desserts, these vegan peanut butter banana cookies are great for that! Along with my favorite gluten free fruit pizza.

3 Ingredients for Peanut Butter Banana Cookies

You’ll need:

• Peanut Butter – I recommend a natural peanut butter, like my all-time favorite brand. If you like some crunch, you could use crunchy peanut butter. Almond butter, cashew butter, sunflower butter or soy butter are great alternatives to peanut butter!
• Bananas – The riper the better for a sweeter product and more ease with mashing. Ripe bananas produce the best results!
• Oats – Any type of oats will do – make sure to get gluten-free if you need them to be. 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, 3-ingredient peanut butter cookies have no added sugars and hence, can be a great peanut butter recipe for baby or toddlers.

I also like to add a pinch of salt (specifically, flaky sea salt) on top, as it makes a big difference in exaggerating the already delicious flavor.

I promise you, 3 ingredient peanut butter oatmeal cookies will be your new method for simple meal prep for snacks during the week.

How To Make Vegan Banana Peanut Butter Oatmeal Cookies

You’ll start by mashing your ripe bananas in a large mixing bowl. Next, mix in your oats.

It may feel a little thick, so having mushier (ie – riper) bananas helps. 

Lastly, mix in your peanut butter in the large bowl until the batter is smooth.

Since banana peanut butter cookies are vegan and have no raw eggs, you can taste as you go along!

Next, line your baking sheet with parchment paper and divide the batter into 12-15 scoops using a cookie scoop.

I like to use the back of a fork to gently flatten them.

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

Did You Know?

If you want 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 to firm up before enjoying.

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!

Expert 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, like brown sugar, coconut sugar, or maple syrup, at all. 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. Make sure you keep an eye on them!
• 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 – To safely store 3 ingredient banana oatmeal cookies in the freezer, stick them in a freezable ziplock bag (these are my favorite) or airtight container. 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, melted chocolate, nuts/seeds, cocoa nibs, raisins, vanilla extract, pumpkin, etc. The options are limitless.
