Preheat Oven & Prep Tin: Preheat your oven to 356ºF (180ºC) fan-forced. Grease a 9-inch x 5-inch (23cm x 13cm) loaf tin with butter and line it with parchment paper. For non-stick tins, line the base with parchment and lightly grease and flour the sides for smooth cake release. Set aside.
Mash Bananas: In a large mixing bowl, mash the bananas with a fork until smooth.
Add Wet Ingredients: Whisk in the egg and oil for 15-20 seconds, ensuring the oil is well combined with the banana mixture.
Whisk in Sugar & Salt: Add the sugar and salt, whisking for another 15-20 seconds until well incorporated.
Add Dry Ingredients: Sift the flour, baking soda, cinnamon, and nutmeg directly into the bowl. Gently whisk until just combined, being careful not to over-mix.
Fold in Carrot: Gently fold in the grated carrot, making sure it's evenly distributed throughout the batter.
Pour and Smooth Batter: Transfer the batter into the prepared tin, smoothing out the top.
Bake: Bake for 35-40 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Cool: Allow the cake to cool in the tin for 10 minutes before transferring it to a wire rack to cool completely.
Maple Syrup Glaze: Once cooled, brush the cake with maple syrup. Alternatively, you can frost the cake with your preferred frosting such as a cream cheese frosting. Serve & Enjoy: Slice and serve the cake once it's completely cooled. Enjoy!
