Ingredients that you will need for the recipe of peanut butter oatmeal banana cookies:

Guess what? You will need only these 3 ingredients for the cookies

  • Banana: you can find this ingredient even at your neighbor, even if he is not vegan, yeah.

Try to use very ripe bananas, they are sweeter.

If your banana is not very ripe, you can still use it, though I would suggest adding some extra sweetener, such as maple or agave syrup.

I would avoid granulated sugar because I am afraid it will not melt during baking, and you don’t want to feel sugar chunks in your cookies, trust me.

2-3 tbsp of any liquid sweetener should be enough.

  • Old-fashioned rolled oats or simple instant oats: well, all the recipes that I saw with peanut butter oatmeal cookies are made with uncrushed, whole oats.

Yes, they are delicious, but the cookies don’t look so appealing and, let’s face it, everyone is tired of simple oats.

That is why I blend the oats to transform them into flour.

That way, the taste of the cookie’s changes – they become more delicious: crunchy outside and soft inside. YOU CAN use unblended oats, but if you have a blender, sacrifice another minute of your life by making flour out of them.

It does worth it, trust me.

Another thing to pay attention to is the gluten-free certificate of oats. If you are eating gluten-free, be careful when choosing oats. For more information about gluten-free oats, check out this article.

Yes, oats are gluten-free normally, but during the process of production, they add extra ingredients for preservative reasons, which normally include gluten. So, keep that in mind.

  • Peanut butter: for this recipe, I use creamy peanut butter.

However, crunchy PB would work fine as well.

I mean, you can either add crunchy PB, or creamy PB and peanuts.

It’s the same thing. If you use crunchy peanut butter, a nice idea would be to add 2-3 extra tsp of it.

Extra ingredients possibilities for peanut butter oatmeal banana cookies

First of all, you should know that for 9 cookies, you don’t have to use more than 0.5 cups of those extra ingredients.

Otherwise, the cookie dough will not stick together, so you won’t be able to make the cookie shape.

For example, you can add 0.25 cup of an extra ingredient and 0.25 cup of another. Or 3 extra ingredients that don’t exceed 0,5 cup in total.

Ok. And now, I will give you some examples of ingredients that you can add to your peanut butter oatmeal banana cookies.

  • Dried fruits: figs, raisins, dates, prunes, apricots and so on. They will give an extra sweetener to your cookies (the cookies are not very sweet by themselves). Besides that, dried fruits have antioxidants and fiber, which is very beneficial for your health.
  • Nuts: almonds, cashews, pecans, walnuts (my favorite extra ingredient so far), pine nuts, pecans, hazelnuts, Brazilian nut, macadamias. All of them will add extra protein and healthy fats to your cookies. Also, I love the crunchiness of them, especially when baked in those cookies.
  • Seeds: chia, flax, sunflower seeds, pumpkin and so on. Your body will tell you “thank you” after that. They absorb bad things in your body and push them out of it. SO many scientific experiments prove that they are good for digestion, especially when talking about chia and flax seeds. You probably won’t feel them in your cookies, but those extra benefits make the difference.

How to make the cookies?

Firstly, blend the oats to transform them into flour. This is an optional step, but it makes a lot of difference. You can also buy directly oat flour if you don’t have a blender.

Next, mash into a deep bowl 1 ripe banana. Then, add the peanut butter and oats.

As an extra step, consider adding some other ingredients, such as dried fruit, nuts or seeds (but no more than 0.5 cups in total). For instance, I added 0.3 cups of chopped walnuts.

Mix everything until well combined.

After the cookie dough is done, take around 2-3 tbsp of the dough and shape it into a cookie form. In total, you should make around 9 cookies.

Then, with a fork, press onto the cookies to spread them a bit more (they won’t spread when baking). This also helps if you want them crunchier on the outside (watch the video for a more comprehensive understanding).

Bake the cookies for 15 minutes on 175 C/350 F.

Let them cool on a grid baking tray for about 20 minutes or so.

How to store these 3 ingredients peanut butter oatmeal banana cookies?

  • At room temperature for up to 2 days. Put a kitchen towel on top to prevent from hardening.
  • In the fridge for up to 5 days. Store in an air-tight container.
  • Freeze for up to 3 months. When you are ready to serve, warm them up in a microwave or in the oven for around 5 minutes.

TIPS ON MAKING THE COOKIES

  1. You can buy directly oat flour if you don’t have a food processor or you don’t want to invest time in this. This one is gluten-free oat flour.
  2. The cookies are not very sweet. Add some extra liquid sweetener if you like. For example, maple syrup. This brand is the best as far as I know.
  3. These 3 ingredients are the base for the cookies, but you can add extra ingredients to your peanut butter oatmeal banana cookies if you like (maximum 0.5 cups of extra ingredients). For example, you can add walnuts (as I did), hazelnuts, almonds, raisins or other fried fruits, coconut flakes and so on.
