Preheat your oven to 175°C (350°F). Lightly grease a 9x5 inch loaf pan and set aside.
In a large bowl, mash the ripe bananas with a fork until smooth, leaving some small lumps for texture.
Add the creamy peanut butter to the mashed bananas and stir until fully integrated, creating a fragrant, nutty aroma.
In a separate bowl, whisk together the flour, baking soda, and a pinch of salt to evenly distribute the leavening agents.
Pour the honey or maple syrup into the banana-peanut mixture, then crack in the eggs and whisk everything together until the mixture is glossy and smooth.
Gradually fold the dry ingredients into the wet mixture with a spatula, mixing gently until just combined—be careful not to overmix to keep the loaf tender.
If desired, fold in chopped nuts or chocolate chips for extra texture and flavor.
Pour the batter into your prepared loaf pan, smoothing the top with a spatula. Sprinkle additional nuts or chocolate chips on top if you like.
Bake in the preheated oven for 50-60 minutes. The loaf is ready when the top is golden and a toothpick inserted into the center comes out clean.
Remove the bread from the oven and let it cool in the pan for about 15 minutes—this helps set the crumb.
Transfer the loaf to a wire rack and cool completely. Once cooled, slice with a serrated knife and enjoy the moist, nutty aroma.
