Pre-heat oven to 180°C/160°C fan/ 375°F.
Beat eggs until light, then fold in the flour, followed by cocoa powder, honey, olive oil and mashed bananas. Finally, add the baking powder and mix until just combined.
Divide the mixture into the muffin tin filling ⅔ of each mould.
Bake in the oven for about 20 minutes, or until a toothpick inserted into the center comes out clean.
Remove the muffin tin from the oven, allow to cool slightly, then remove the muffins and serve at room temperature.
