Take your regular banana bread up a notch by throwing in some juicy blueberries. This twist blends the comforting sweetness of traditional banana bread with pockets of fresh berries, making a wonderful flavor combo that turns each bite into a tasty surprise. After trying lots of different fruit pairings, I've found this mix to be my favorite way to jazz up the old classic.
I brought this to a Sunday brunch last week, and many folks said it had just the right mix of banana and berries - not overly sweet, with lovely fruit bursts in every mouthful.
Key Ingredients
- Ripe Bananas: Grab 4 big ones with lots of brown spots for maximum flavor
- Fresh Blueberries: Look for round, firm ones to get the juiciest outcome
- Sour Cream: Don't forget to warm it up before mixing for best results
- Butter and Oil Combo: This pair creates the perfect balance of taste and moisture
- Eggs at Room Temp: Really important for good mixing
- Real Vanilla Extract: Brings out the best in both the bananas and berries
Step-by-Step Baking Guide
- Making Your Base:
- First, mix all your dry stuff in a big bowl. In another bowl, squish your bananas until mostly smooth but still a bit chunky. Add your warmed-up sour cream, eggs, melted butter, oil, and vanilla to the bananas and stir until everything's mixed well.
- Careful Mixing:
- Add your wet stuff to the dry stuff, folding gently just until it comes together. Don't mix too much or your bread will get tough. Stop once you can't see any dry flour. Your batter should be thick but still easy to stir.
- Adding the Berries:
- Gently fold in one cup of blueberries, trying not to smash them. Keep half a cup aside for the top. This way, you'll get berries throughout and a pretty berry-spotted top.
- Baking It Right:
- Pour your mixture into a 9x5 inch pan lined with parchment, then scatter the saved berries on top. Bake at 350°F for about 75-78 minutes, until a toothpick comes out with just a few bits stuck to it.

I first came up with this recipe when I wanted something fancier than plain banana bread for a special get-together. Adding blueberries didn't just make it prettier - it totally changed how good it tasted.
Getting The Temperature Right
All your ingredients need to warm up to room temperature before you start. Cold sour cream or eggs will make your bread heavy and uneven. I usually put everything out an hour ahead and make sure my butter is just melted, not hot enough to cook anything.

Keeping It Fresh
This bread stays moist for 2-3 days when wrapped tight at room temperature. Cover it well with plastic wrap or put it in a sealed container. For keeping it longer, you can freeze individual slices with parchment between them for up to three months.
Try It As Muffins
You can easily make this into muffins by filling paper-lined cups about 3/4 full. They'll need less time - around 22-24 minutes in the oven. Keep an eye on them toward the end. You'll get about 14 muffins, which are perfect for grabbing on busy mornings.

Wrapping Up
This Blueberry Banana Bread brings together two favorite fruits perfectly. Every slice gives you that warm, familiar banana bread feeling with surprising pops of berry sweetness. It's great when you've got overripe bananas or want something special to share with friends. It's become more than just another quick bread in my kitchen - it shows how adding just one simple twist can completely refresh an old favorite.
