This peanut butter banana bread is your answer to using up extra ripe bananas while bringing a nutty, nostalgic spin to classic banana bread. Moist and tender inside with a mellow richness from creamy peanut butter, it’s the kind of quick bake that fills the kitchen with a cozy aroma and leaves friends asking for seconds.
The first time I baked this was after an especially busy week when I needed comfort food I could also pack in school lunches. It’s become my go-to whenever I want a little something extra from my banana bread.
Ingredients
- Ripe bananas: The riper the bananas the sweeter and more flavorful your bread will be Choose fruits heavily speckled or even mostly brown

- Fill the Pan:
- Pour the batter into the prepared loaf pan and smooth out the top with your spatula This makes for even baking and a professional finish

My favorite part is watching swirls of peanut butter caramelize on top while baking. Once my daughter tried it warm from the oven she declared it the best after school treat ever—now it is our weekend baking tradition.
