Instrucciones para la impresión en alta definición
- Precalentar el horno a 350°F (180°C).
- Line a large cookie sheet with parchment paper. Slightly oil the paper with cooking oil spray. Set aside.
- Mash the bananas and pack them in a 3/4 cup measuring cup to measure precisely.
- In a large mixing bowl, combine all the ingredients: mashed banana, rolled oats, oat flour, vanilla extract, and cinnamon. Stir until fully combined, and a sticky cookie dough forms.
- Use a cookie dough scoop to form 15 cookie dough balls on the prepared baking sheet, leaving an inch between the cookies. The dough is sticky, and that's normal.
- Lightly oil the back of a measuring teaspoon to press down the center of each cookie dough ball and form a cavity in the center.
- Place a little jam or preserve in the cavity of each cookie; don't fill the cavity up to the top, or it will overflow in the oven. Fill up to 3/4 level.
- Bake the cookies for 13-15 minutes at 350°F (180°C) until golden brown.
- Let the cookies cool on the cookie sheet for 15 minutes, then transfer them to a cooling rack for 30 minutes.

Ingredientes y sustituciones
Solo necesitas unos pocos ingredientes sencillos para preparar esta receta. Aquí te explicamos cómo elegirlos y sustituirlos.

- Plátano maduro – This provides natural sweetness and acts as a binder to hold the cookies together without using eggs or oil. Unsweetened applesauce also works well if you prefer a non-banana flavor.
- Copos de avena – These form the hearty base of the cookie. You can use gluten-free certified oats if necessary, or swap them for quinoa flakes, though you might need slightly more flakes as they absorb less moisture. Quick oats are another good option here.
- Harina de avena – This brings a chewy texture and helps firm up the dough structure. You can use extra rolled oats or extra quinoa flakes if you don’t have flour on hand.
- Extracto de vainilla – It adds a classic, warm cookie flavor to the batter. You can skip this or try almond extract for a nutty twist.
- Canela – This adds a warm, spicy note. You can leave it out if you prefer a plain oatmeal cookie base.
- Raspberry Preserve – This creates the sweet, fruity center. Strawberry or blueberry jams work great too. Melted dark chocolate or nut butter are tasty options, but you must add them after the cookies have baked and cooled.

Permítanme compartirles algunos consejos más para lograr galletas perfectas.
- Variaciones de relleno – You can swap the raspberry preserve for other jams, or even use melted dark chocolate or nut butter. Just remember to add chocolate or nut butter after the cookies have baked and cooled so they don’t melt messily in the oven.
- Potencia el sabor – Adding vanilla extract or ground cinnamon gives the dough a wonderful aroma and taste. You can use both for a spiced cookie or switch to almond extract for a different profile.
- Edulcorante de frutas – If you aren’t a fan of bananas, unsweetened applesauce is a perfect swap. It keeps the recipe oil-free while acting as the binder; just make sure to measure it precisely.



could I use Almond Flour instead of oat flour?
No, but I have a recipe of almond flour thumbprint cookie recipe aquí specially designed to use almond flour.
Can I use self-rising flour instead? Thanks
No, it won’t work here. But if you want a cookie reciep using banana and self-rising flour try my 3-ingredient banana cookies.
How could I incorporate dried figs that I processed down to a paste Do you think it could be used instead of the jam Might need some sweetness?
What’s your opinion
Muchas Gracias
You can fill the cookies with dried fruit paste. Simply make the paste, need fill the hole up to the 3/4 their level. It won’t be as sweet as jam or preserve, but you can add maple syrup in your dried fruit paste to up the sweeteness.
Thank you for sharing this recipe! Loved it ❤️
Gracias!
I have frozen bananas, will they work for this recipe?
Frozen bananas could work, but watch out, they release more moisture, it means you will need more oat flour.
