Three Ingredient Cookies

Three Ingredient Cookies are the best thing I've baked in a long time. They are quick, healthy, versatile, sugar-free, wheat-free and gluten-free (just check the oats are gluten-free). They are perfect for baking with young kids as they are so quick and straightforward. The best thing about them is that they require only three ingredients and they are really yummy too.

To make Three Ingredient Cookies you only need bananas, oats and then a handful of whatever you have to hand - dried fruit, chocolate chips, nuts, seeds etc. You can also add extra flavours such as ground cinnamon or vanilla extract if you fancy.

I used a tablespoon of pumpkin seeds and a teaspoon of poppy seeds in the cookies in the photos here. I decorated them with a few extra pumpkin seeds on the top to make them look pretty. As far as cookies go, these are pretty good for you.

Three Ingredient Cookies: Makes 8 cookies:

  • Time: 10 mins prep + 15 mins baking

  • Cost: 7p per cookie (based on 8 cookies with walnuts)

  • Calories: 171 per cookie (based on 8 cookies with walnuts)


  • 2 ripe bananas

  • 100g rolled oats

  • 30 - 50g chopped nuts / dried fruit / seeds / chocolate chips

  • Pinch cinnamon / mixed spice / drop of vanilla extract etc (optional)


  1. Pre-heat the oven to gas mark 5 / 180 C. Line a baking sheet with grease proof paper and grease it very lightly with sunflower or vegetable oil.

  2. In a large bowl, mash the bananas until they are fairly smooth. Stir in the oats and extra 'bits' until combined.

  3. Wet your hands and roll the mixture into 8 balls. Place the cookie balls onto the grease proof paper and squash them with your fingers to make a round cookie shape.

  4. Bake for 15 minutes until firm but springy and a little coloured. Best eaten within 24 hours and kept in an airtight container. You can freeze them too.

Here's some other combinations I've tried - walnut & cinnamon (add 30g of chopped walnuts and a pinch of cinnamon), cranberry & mixed spice (50g cranberries and a pinch of mixed spice) and chocolate chip & vanilla (40g chocolate chips & 1/2 tsp vanilla extract). What combinations do you think you might try?
