Preheat the oven to 180 degrees Celsius. Grease a loaf tin, line with baking paper and set aside.
In a medium sized mixing bowl, mash the bananas.
Add the eggs, extra virgin olive oil and vanilla extract to the banana and whisk to combine.
Add the almond flour to a separate, larger mixing bowl. Sieve the tapioca starch, rice flour and baking flour into the bowl. Add the rapadura sugar and linseed meal. Use a clean & dry whisk to combine. Break any lumps of sugar up with the back of a spoon.
Pour the wet ingredients into the dry ingredients and stir through with a wooden spoon until all of the flour is incorporated into the wet ingredients.
Pour the batter into the baking paper lined tin and top with a peeled banana, sliced in half lengthways. Place into the oven and bake for 45 minutes.
After 45 minutes, place a sheet of aluminium foil over the top of the banana bread and cook for a further 15 minutes.
Allow the banana bread to cool in the tin for 5 minutes before transferring to a cooling rack. Wait until room temperature before slicing.
Notes
Storage
Once banana bread has cooled to room temperature, store in an airtight container at room temperature for up to 1-2 days, before transferring to the fridge to store for up to another 3 days. To freeze, slice the banana bread and place a small piece of parchment paper between each slice of banana bread. Freeze in an airtight container for up to 6 months.
