Preheat the oven to 180°C (160°C fan) or 350°F. Line a 12-cup muffin pan with paper liners or lightly grease each cup.
Peel the bananas, place them in a large mixing bowl, and mash them thoroughly with a fork.
Add the milk, egg, and vegetable oil to the mashed bananas. Whisk until evenly combined.
Add the flapjack mix and ground cinnamon. Stir gently just until no dry patches remain; do not overmix.
Fold the chopped walnuts into the batter, reserving a small amount for the tops if desired.
Divide the batter evenly among the 12 prepared muffin cups, filling each about three-quarters full. Sprinkle over the reserved walnuts.
Bake for 18–22 minutes, or until the muffins are golden and a toothpick inserted into the center comes out clean.
Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack. Serve warm or leave to cool completely.
