Notes

  • You don’t have to blend your old fashioned rolled oats, but it does help with the texture. The blended oats make the cookies more solid and the added whole oats add a lovely chunky mouth-feel. You can, however, just use the whole oats without blending.
  • This recipe makes 6 thick medium-sized cookies. You can however make smaller or thinner cookies, simply reduce the cooking time to 8 minutes.
  • You will know the cookies are ready when the edges turn golden.
  • Make sure to use very ripe bananas!
  • As all bananas come in different shapes and sizes, if your banana is smaller, your cookie dough will be too dry. If your banana is too big, your cookie dough will be too wet. This is why I recommend weighing your banana. Otherwise, you can adjust the cookie dough texture by adding a splash of maple syrup if it's too dry or adding some extra oats if it's too wet.
  • If you want your cookies to be sweeter, add a bit of maple syrup or honey.
  • You can mix things up by swapping out the chocolate for one of the following:
Raisins, sultanas or currants.
Chopped nuts.
Sliced bananas.
