Pre-heat the oven to 180C fan-forced and line a 12 hole-muffin tin with liners.
In a large bowl, sift the coconut flour, baking powder and bicarbonate of soda together and mix.
In another bowl, whisk together the honey, eggs, olive oil, coconut milk and bananas.
Make a well in the flour and carefully stir in the wet ingredients until just combined.
Divide between the muffin liners.
To make the topping, melt the honey and coconut oil together.
Combine the oats and coconut in a bowl and pour over the honey oil and stir.
Divide the topping between the muffins.
Bake for 20-25 minutes or until a cake tester inserted in the middle comes out clean.
