Put the flour, salt, yeast and butter into a bowl.

Slowly add water to the bowl and mix carefully by hand until the dough becomes elastic.

Knead the dough for 5 minutes, then cover the bowl and set aside to rest for 2 hours.

Divide the dough into two, then add a chopped banana to each, using your hands to ‘mash’ the banana into the mixture.

Your dough will now be sticky, so add enough muesli to each to regain the original texture.

Line a baking tray.

Roll each dough into a ball, then press into the bowl of muesli, so that the dough becomes completely coated.

Place the loaves on the baking tray and leave to rise for 1–2 hours.

Preheat the oven to 200°C/400°F/gas mark 6.

Using a knife, deeply score the top of each ball into 8 sections.

Bake the loaves for 25–30 minutes, then transfer to a wire rack to cool.
