Line 12 muffin tins with liners and preheat your oven to 350°F / 175°C.
In a medium-sized bowl, whisk together flour, baking soda, baking powder, salt, cinnamon and sugar.
In another medium-sized bowl, lightly beat the eggs.
Add honey, canola oil, vanilla and mashed bananas.
Add the wet mix to the dry mix, but just until combined.
Spoon about 1/4 cup of the batter into each liner. Then drop about 1 tablespoon of Nutella over the batter. Then fill the liners with the remaining batter.
Add another spoonful of Nutella to the top and swirl around with knife. If the Nutella is giving you trouble, you can put some in a bowl and microwave it for a few seconds until it’s a little melted.
Bake for about 18 – 22 minutes or until a toothpick comes out clean.
