Banana Bread Recipe With Oil and Butter: Dual-Fat Moisture Magic

This banana bread recipe delivers moist, tender crumb through a unique combination of oil and butter. The dual-fat approach creates a texture that stays rich and soft for days.

I developed this method after testing countless variations, and the balance of these two fats makes all the difference. The butter adds flavor depth while the oil ensures long-lasting moisture in every slice.

The result is a loaf with a golden crust and an interior so moist it borders on decadent. Perfectly sweet with just the right density, this version will become your go-to banana bread.

Ready in under an hour, it transforms overripe bananas into something extraordinary. Here’s how to make it right every time.

Ingredients for Banana Bread Recipe with Oil and Butter

Overripe bananas, flour, and a clever mix of fats create this perfect loaf.

The bananas are key here. Look for ones with lots of brown spots—the riper, the better (they’ll be sweeter and mash easier). I always grab a few extra bunches and let them sit on the counter until they’re nearly black. The butter should be unsalted so you control the sodium. Plugra or Kerrygold are great options if you want to splurge, but store brands work fine too.

No walnuts? Pecans or chocolate chips are great swaps. Out of vanilla? Skip it—the bananas add enough flavor. If you only have salted butter, reduce the added salt by half. The oil can be any neutral type: canola, vegetable, or even melted coconut oil (though that adds a slight flavor). The cinnamon is optional but worth the extra minute.

This bread stays moist for 3-4 days at room temperature, wrapped tightly. Freeze slices for up to 3 months—just thaw overnight. The dual-fat combo keeps it tender even after freezing. Best served warm, but honestly, it’s delicious any time.

Step-by-Step Instructions for Banana Bread With Oil and Butter

This proven method ensures a perfectly moist crumb with a tender, golden crust every time.

Step 1: Mash Bananas and Combine Wet Ingredients

In a large mixing bowl, mash the 4 whole Overripe Bananas with a fork until mostly smooth with some small lumps remaining. The bananas should be very ripe with plenty of brown spots—this ensures maximum sweetness and moisture.

To the mashed bananas, whisk in the 1 cup Granulated Sugar, 2 whole Large Eggs, 0.5 cup Unsalted Butter (melted and cooled), 0.5 cup Vegetable Oil, and 2 tsp Vanilla Extract until fully combined. The combination of butter and oil creates a rich, moist texture that’s the signature of this bread.

Step 2: Whisk Together Dry Ingredients

In a separate medium bowl, sift together the 2 cups All-Purpose Flour, 1 tsp Baking Soda, 0.5 tsp Salt, and 1 tsp Ground Cinnamon. Sifting the flour removes lumps and aerates it, which helps create a lighter texture in the finished bread.

If using, fold the 0.5 cup Chopped Walnuts into the dry mixture. This ensures they’re evenly distributed throughout the loaf rather than sinking to the bottom during baking.

Step 3: Combine Wet and Dry Mixtures

Gradually add the dry ingredients to the wet mixture, stirring just until combined. Do not overmix—the batter should be thick but still slightly lumpy. Overmixing develops gluten, which can make the bread dense instead of tender.

The dual fats in this recipe (butter and oil) work together to keep the bread exceptionally moist, even days after baking. The batter will be thicker than a typical cake batter but should still pour easily into the pan.

Step 4: Bake to Golden Perfection

Pour the batter into a greased 9×5-inch loaf pan, spreading it evenly with a spatula. Bake in a preheated 350°F oven for 55-65 minutes, or until a toothpick inserted into the center comes out clean or with only a few moist crumbs attached.

Check the bread at the 55-minute mark. If the top is browning too quickly, tent the pan loosely with aluminum foil. The bread is done when the top is deep golden brown and springs back lightly when pressed.

Step 5: Cool and Serve

Remove the pan from the oven and let the bread cool in the pan for 10 minutes. This allows it to set slightly, making it easier to remove without breaking. Then, transfer the loaf to a wire rack to cool completely before slicing.

For the best texture, wait at least 1 hour before slicing. This resting period allows the moisture to distribute evenly, ensuring each slice is tender and flavorful. Serve at room temperature for the ideal experience.

Regional Styles of banana bread recipe with oil and butter

Southern Comfort Style

In the South, we love adding 1 cup crushed pineapple (drained) to the batter for extra moisture and a subtle tropical twist. The acidity also balances the sweetness beautifully. I fold it in with the wet ingredients before combining with the dry mixture. 🌟

New England Spiced

New England bakers often include 1 tsp ground nutmeg and ½ tsp ground cloves alongside the cinnamon for a warmer spice profile. This version pairs perfectly with a hot cup of tea on a chilly morning.

Midwest Hearty

For a heartier loaf, Midwestern cooks add ½ cup old-fashioned oats to the dry ingredients. This gives the bread a slightly chewy texture and makes it feel more substantial. I recommend toasting the oats lightly first for extra flavor.

West Coast Nutty

On the West Coast, it’s all about the nuts—pecans or macadamias often replace walnuts. For a California twist, add ¼ cup toasted coconut flakes to the batter. The coconut adds a delightful chew and tropical note. 🥥

Texas Bold

Everything’s bigger in Texas, including the flavor! Add 1 chopped jalapeño (seeds removed) and ½ cup shredded cheddar cheese for a sweet-spicy kick. The cheese creates a beautiful golden crust when baked.
