Line a loaf tin with silicone paper and preheat the oven to 150C (fan forced)
Sieve the gluten free flour, sugar, spices, bicarb soda, linseed meal and chia seeds into a bowl and whisk to combine.
In a separate bowl combine the oil, eggs, milk and golden syrup. Mix until emulsified.
Pour the wet ingredients along with the mashed banana into the dry ingredients and mix until just combined.
Pour into the lined loaf tin smooth out. Lay the 2 halves of banana on top and scatter with some flaked almonds.
Place onto the middle shelf of the preheated oven and cook for 1 hour or until cooked through when tested with a skewer. Allow to cool in the pan for 10 minutes then turn out onto a wire rack to cool completely.
Keep wrapped in the fridge, to be eaten within a week, or slice, wrap and freeze for up to 3 months.
