Ingredients You’ll Need

See how a handful of humble ingredients come together to craft Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat.

- Large Eggs: Bind everything together while lending structure and extra richness.
- Mashed Ripe Bananas (about 3–4 medium): Use bananas with brown speckles for the deepest banana flavor.
- Vanilla Extract: Enhances sweetness and gives a warm bakery aroma to both the bars and the frosting.
- All-Purpose Flour: The foundation of the bars, keeping them sturdy but still tender.
- Baking Soda: Ensures the bars rise beautifully and stay light.
- Salt: Just the right amount to balance sweetness and highlight the banana and butter.

How to Make Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking pan— parchment paper makes for even easier removal, but a light coating of butter or nonstick spray works wonders too. Setting up your pan ahead of time means no scrambling once your batter comes together.
Step 2: Cream the Wet Ingredients
In a large mixing bowl, blend together the sugar, sour cream, softened butter, and eggs. Beat on medium speed until the mixture is thick, creamy, and a little bit fluffy. This step lays the groundwork for the exceptional texture that defines Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat.
Step 3: Add Bananas and Vanilla
Mash your ripe bananas until mostly smooth (a few small lumps are welcome), then fold them into the creamy mixture along with the vanilla extract. The bananas infuse the batter with natural sweetness and keep the bars tender and moist.
Step 4: Stir in Dry Ingredients
Add the flour, baking soda, and salt to your wet mixture, stirring gently just until no dry streaks remain. Take care not to overmix; this step ensures your Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat stays perfectly soft instead of tough. Fold in the walnuts now if you’re after a bit of crunch.
Step 5: Bake the Bars
Spread the batter evenly into the prepared pan— a spatula helps get every last bit. Bake in the center of the oven for 20–25 minutes, or until the edges look golden and a toothpick inserted in the center comes out clean. The aroma at this stage is guaranteed to have everyone peeking into the kitchen.
Step 6: Brown the Butter for Frosting
While the bars bake, slowly melt the butter for your frosting in a saucepan over medium heat. Let it bubble gently until the solids turn a deep golden brown and it smells wonderfully nutty— stir often and watch closely so it doesn’t burn. This browned butter is the magic behind that crave-worthy, toasty flavor.
Step 7: Make and Spread the Frosting
Remove the browned butter from heat and whisk in the powdered sugar, a splash of milk (start with one tablespoon), and vanilla extract. Stir until smooth and luscious, adjusting the milk for your favorite spreadable consistency. Once the bars come out of the oven, pour and gently spread the frosting over the warm bars; it’ll melt slightly to create a dreamy, glaze-like finish.
Step 8: Cool and Slice
Let your Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat cool to room temperature— this helps the frosting set just right. Once cooled, slice into bars or squares and get ready to watch them disappear fast!
How to Serve Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat
Garnishes
A classic finish is a scattering of chopped walnuts on top of the frosting, which adds a welcome crunch and makes each square look extra inviting. For a touch of whimsy, you can sprinkle a little cinnamon or dust with powdered sugar before serving.
Side Dishes
Pair your bars with a steaming mug of coffee for a cozy breakfast, or alongside fresh fruit for a well-rounded snack plate. At a party or potluck, a scoop of vanilla ice cream tucked next to these bars is never a bad idea.
Creative Ways to Present
If you want to impress, cut bars into mini squares and arrange them on a tiered platter for afternoon tea. Wrap individual pieces in wax paper and twine for picnic-ready treats, or serve warm with a drizzle of caramel sauce for an extra touch of decadence.
Make Ahead and Storage
Storing Leftovers
Keep leftover bars covered at room temperature for up to two days, or refrigerate in a tightly sealed container for four to five days. Storing in the fridge helps keep the frosting set and the bars moist.
Freezing
Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat freezes beautifully! Once completely cooled and frosted, layer bars between parchment in an airtight container and freeze for up to three months. Thaw at room temperature when you’re ready for a homemade treat.
Reheating
For the just-baked experience, warm individual bars in the microwave for 10–15 seconds. If you love an oozy, almost-melted frosting, pop an unfrosted bar into a 300°F oven for a few minutes, then add a fresh swipe of frosting before serving.
FAQs
Can these bars be made without the frosting?
Absolutely! The bars are delicious all on their own, with their moist crumb and intense banana flavor. Feel free to omit the frosting or substitute with a light dusting of powdered sugar if you prefer.
Can I use Greek yogurt instead of sour cream?
Yes, full-fat Greek yogurt is a fantastic substitute for sour cream in this recipe and will yield the same tender, moist results.
How can I make these gluten free?
Swap the all-purpose flour for your favorite 1:1 gluten free baking blend. Results may vary slightly, but you’ll still get all the signature flavor and texture of Banana Bread Bars: The Ultimate Recipe for a Deliciously Moist Treat.
Should bananas be weighed or measured by cups?
The best approach is to mash your bananas and then measure the amount in cups, as size and shape can vary. For perfect results, use 1 3/4 cups mashed banana— that’s about three to four medium bananas.
Can I make this in a smaller pan?
You can halve the recipe and bake it in an 8×8-inch pan. Just keep an eye on the bake time, as it may be a few minutes shorter.
