Peanut Butter Banana Bread

Peanut Butter Banana Bread made with ripe bananas and creamy peanut butter. This easy recipe creates a soft, moist loaf full of rich flavor — perfect for breakfast, snacks, or a sweet homemade treat.

I’ll never forget the morning my son looked at his toast with peanut butter and banana slices and said, “Mom, why don’t you make banana bread with peanut butter in it?” Out of the mouths of babes, right? I’d been making regular banana bread for years, and it never once occurred to me to add peanut butter, even though that classic combination is literally one of his favorite snacks.

At first, I brushed it off as one of those random kid ideas that sounds weird but probably wouldn’t work. But the thought stuck with me all day. That night, lying in bed, I kept thinking about how well bananas and peanut butter go together on toast, in smoothies, on sandwiches. Why not in banana bread? The more I thought about it, the more obvious it seemed.

The following weekend, when my usual batch of brown bananas appeared on the counter like clockwork, I decided to experiment. I was a little nervous about messing with my tried-and-true recipe, but I figured if it didn’t work out, we’d just have a slightly weird loaf that my peanut butter-obsessed son would probably eat anyway.

I mixed up my standard banana bread batter – mashed overripe bananas, melted butter, sugar, and eggs – but this time I added a generous half cup of creamy peanut butter right into the mix. Watching it swirl into the batter, creating these beautiful ribbons of peanut butter throughout, I started to feel more confident about this whole experiment. For good measure, I also stirred in some chocolate chips, because if we’re doing peanut butter and banana, chocolate just makes sense.

As it baked, my kitchen filled with the most incredible smell – sweet banana mixed with that warm, nutty peanut butter aroma that makes everything better. When I pulled it out, the top was golden and slightly cracked, looking absolutely perfect. I could barely wait for it to cool before slicing into it.

That first bite was a revelation. The peanut butter added this rich, almost creamy texture to the banana bread, and the flavor combination was exactly like that classic PB and banana sandwich but somehow elevated into something special. My son took one bite, gave me the biggest grin, and said, “See, Mom? I told you it would be good!”

Frequently Asked Questions

1. Can I use any type of peanut butter?

Creamy peanut butter works best for a smooth texture, but you can use crunchy if you like little bits of peanuts throughout. Just avoid natural peanut butters that separate easily, as they can change the texture.

2. Can I make this recipe without eggs?

Yes, you can replace each egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water). It still bakes up moist and rich.

3. Can I add chocolate chips or nuts?

Absolutely! Chocolate chips, chopped peanuts, or even mini Reese’s pieces are delicious add-ins. Stir about ½ cup into the batter before baking.

4. What type of bananas should I use?

Very ripe bananas with lots of brown spots are perfect. They blend easily and give that sweet banana flavor that pairs beautifully with peanut butter.
