You even have the option of adding flavors such as cocoa powder, vanilla extract, or a small pinch of salt to enhance the other flavors.

🧾 Key ingredients

These 3 ingredient oatmeal cookies are simple to bake with ingredients that are easily accessible. You will find all the necessary items at your local grocery store, or they might already be in your pantry.

Bananas are the star ingredient in this recipe. Overripe bananas are ideal as they are the sweetest and softest, making them easy to mash. They also eliminate the need for additional sugar in the recipe due to their high natural sugar content.

Fine or quick oats lend a hearty texture to the cookies and are a great source of fiber. They also help to bind the cookies together, eliminating the need for flour. Several readers have also gotten great results with rolled oats. 

Peanut butter adds a rich, creamy flavor to the cookies. It also contributes to the fat content, causing the cookies to flatten slightly during baking. I love using my homemade peanut butter.

🥘 Equipment

The most important piece of equipment you will need for this banana peanut butter oatmeal cookies recipe is an ice cream scooper with a trigger release. This handy tool helps guarantee that each cookie is portioned out equally, resulting in a uniform batch of cookies. It also makes the process of shaping and placing the cookies on the baking sheet much easier and faster. 

👩‍🍳 Instructions

Peel the bananas and mash them in a medium-sized bowl and mash with a fork. You can leave some chunks for texture.

STEP 2
Add peanut butter to the mashed bananas. Mix them together until well combined.

STEP 3
After the banana and peanut butter are mixed, add oats to the mixture. Stir until all the ingredients are evenly distributed.

STEP 4
This is the step when you add any flavors or add-ins like chopped nuts, raisins, chocolate chips, cocoa powder, or cranberries.

STEP 5

💡 Expert tip

The most important tip for making these banana peanut butter oatmeal cookies the best they can be is to use overripe bananas. Overripe bananas have a higher sugar content, making them sweeter and softer, which is perfect for this recipe. They are easier to mash and require no additional sugar, guaranteeing your cookies are naturally sweet and healthier.

🔄 Variations

For delicious cookies with an indulgent feel, consider adding white or dark chocolate chips and chunks to your cookie mix. My family and I particularly love white chocolate with cranberries. You can also use carob chips for a healthier option.

If you are a fan of nuts, why not add chopped nuts to your cookies? They will provide a unique texture and nutty flavor to the cookies. You can use cashews, almonds, walnuts, or pecans. Each type of nut will bring a unique flavor and texture to this recipe.

If you like your cookies with a hint of spice, consider adding some cinnamon, ginger, or orange zest. These spices will give your 3 ingredient oatmeal cookies a kick without overpowering the other flavors. Remember to add them in moderation, as they can be quite potent.

🥣 Serving ideas

These banana peanut butter oatmeal cookies are not just a treat but a versatile snack that can be enjoyed in a variety of ways.

For a quick and easy breakfast, pair these cookies with a fresh fruit salad or a kiwi banana spinach smoothie. The sweetness of the cookies compliments the freshness of the fruits, making for a balanced and nutritious start to your day. You could also serve them with a bowl of vegan yogurt topped with granola and berries for a protein-packed breakfast.

As a midday snack, these cookies are perfect on their own. However, if you want to add a bit more substance to your snack, try pairing it with a glass of homemade cashew milk or a cup of your favorite vegan coffee. The creaminess of the milk or coffee balances the hearty texture of the cookies, making for a satisfying snack that will keep you full until your next meal.

If you are serving these cookies as a dessert, consider pairing them with a scoop of vegan ice cream. The cold, creamy ice cream contrasts beautifully with the warm, chewy cookies, creating a dessert everyone will enjoy. You could also serve them with a cup of hot cocoa for a cozy, comforting dessert perfect for those chilly evenings.

❄️ Storing tips

Storing and reheating these banana peanut butter oatmeal cookies is simple, and the flavor remains just as good. 

To store, you can do it for up to two days at room temperature in an airtight container. After that, place them in the refrigerator for up to five additional days. 

Freezing is not recommended for these cookies due to the high moisture content of the bananas. It may result in a mushy texture when thawed. 

To reheat the cookies, you can warm them in a preheated oven at a low temperature for a few minutes. Alternatively, you can also reheat them in the microwave for a few seconds, but be careful not to overheat as they can dry out

Notes

Use ⅓ cup of add-ins (mix and match):

• Chocolate chips (dark or white) – I love the combination of white chocolate chips and dried cranberries.
• Carob chips for an even healthier WFPB-friendly (whole foods plant-based) option.
• Raisins or dried cranberries – Basically, any dried fruit can work here. Although, you need to cut larger fruits like dried apricot into chunks.
• Hot chocolate powder (3 teaspoons at most per batch) – My daughter says “These are the best cookies!”
• Cocoa powder (3 teaspoons at most per batch)
• Chopped nuts (cashews, almonds, walnuts, pecans)
• Seeds (sunflower seeds, pumpkin seeds, hemp seeds)
• Shredded coconut (or even better toasted coconuts) – They also go great with chocolate chips or cocoa powder like in my coconut cookies recipe.
• Vanilla extract (1 teaspoon at most per batch)
• Spices like cinnamon (cause everything is better with cinnamon) or ginger or orange zest. (1 teaspoon at most per batch)
