Preheat the oven to 180°C. Grease 4 mini loaf tins, then line them with parchment paper.
Mash the bananas with a fork, then add the cinnamon, oats and ground almond.
Combine gently, then add the grated apple, elderflower syrup, oil and enough almond milk to get a sticky, but not too thick batter.
Fold in the sultanas, then spoon the mixture into the mini loaf tins.
Bake in the middle of the oven for 20 minutes, then scatter some almond flakes on top and bake for another couple of minutes until the almond bits are golden.
Let them cool in the tin, then serve them warm or at room temperature.
