Preheat the oven to 350° F/ 180° C. Line a large muffin tin with 9 paper cases or grease the holes.

Combine the all purpose flour and the baking powder. Mix very well to blend.

Peel and core the apples and chop them into small pieces. Combine the apples with the sugar and the spices and stir well.

In a large mixing bowl Whisk together the melted butter and the mashed bananas. Add the eggs and whisk again until smooth.

Add the coconut flour and mix to combine.

Fold the apple mixture into the batter.

At the end gradually add the all purpose flour. Mix gently with a rubber spatula until absorbed.

Use an ice cream scoop to divide the batter between the 9 muffin cases. You can fill them almost to the top.

Bake for about 20-25 minutes or until the tops are golden brown and a toothpick inserted in the centre of a muffin which is in the centre of the oven comes out clean.

Let the muffins cool for about 30 minutes before serving them.
