In a large mixing bowl, add the ripe bananas and mash them into a pudding-like consistency with a fork or a potato masher. Then, add the eggs and brown sugar and mix with a whisk until well combined
Add the self-rising flour (I recommend sifting it) and mix until there are no lumps of flour in the batter and it looks smooth. If you want to add add-ins like chocolate chips, nuts, or fruit, this is the time!
Optional: for decoration, slice a banana in half lengthwise, and top the batter with the bananas with the sliced side facing upwards.
Bake in a 180c (350f) preheated oven for 45-55 minutes (depending on the oven) or until a toothpick inserted into the banana bread comes out clean.
Allow the banana bread to cool in the pan for at least 30 minutes, slice, and enjoy!
Notes
Use very ripe bananas. The riper the bananas, the sweeter and more flavorful your banana bread will be. Look for bananas with plenty of brown spots or even fully brown skins.
Mash the bananas thoroughly. Ensure there are no lumps left in the mashed banana mixture. This will help create a smooth, even texture in your bread.
For extra crunch, add chopped nuts of your choice on top of the bread like chopped pecans, almonds, or walnuts.
Bring ingredients to room temperature. Allow the eggs and bananas to come to room temperature before mixing. This will help them incorporate better into the batter.
Don't overmix the batter. Mix the ingredients just until combined. Overmixing can lead to a tough, dense bread.
Check for doneness. Insert a toothpick or skewer into the center of the bread. If it comes out clean, the bread is done.
Let it cool completely before slicing. Allow the banana bread to cool completely on a wire rack before slicing. This will help it set and prevent it from falling apart.
