Banana Bread Recipe With Oil And Butter: Moist Loaf With Double Fat Richness

I’ve spent years perfecting this banana bread, and the combination of oil and butter is the secret to its signature texture. The oil keeps it moist for days, while the butter adds a richness that’s simply unmatched.

This recipe transforms overripe bananas into a tender, golden loaf with a fine crumb and deep flavor. The double-fat approach ensures every bite is decadent without being heavy.

You’ll get a loaf that’s perfectly balanced—sweet, rich, and incredibly moist, with a crust that’s just crisp enough to hold its shape. It’s the kind of bread that disappears quickly.

Bake it today, and your kitchen will smell like comfort itself. Here’s how to make it right.

Ingredients for Banana Bread Recipe with Oil and Butter

Pantry staples plus two ripe bananas make this decadent loaf with signature double-fat richness.

The butter and oil combo is non-negotiable here. Use a neutral oil like canola or vegetable—it keeps the crumb tender for days. For the butter, unsalted is key so you control the salt. I grab mine at Whole Foods for the good stuff, but any supermarket brand works fine. The bananas need to be really ripe—black spots on the peel mean maximum sweetness and moisture.

No oil on hand? Melted coconut oil works in a pinch (adds slight coconut flavor). Out of bananas? Applesauce at the same quantity keeps it moist but changes the taste. The walnuts can be swapped for pecans or omitted entirely. If you’re adding mix-ins like chocolate chips, toss them in a bit of flour first so they don’t sink to the bottom.

This loaf stays moist for 3 days at room temperature wrapped in foil, or 5 days refrigerated. Freeze slices for up to 3 months—perfect for quick breakfasts. The flavor actually deepens after a day, so resist the urge to slice it right away.

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

This method ensures a perfectly moist crumb with that signature double-fat richness you’ll love.

Step 1: Prep and Mash the Bananas

Peel and mash the 4 whole overripe bananas in a large bowl until mostly smooth with a few small lumps remaining. The bananas should be very brown and soft—this is when their natural sweetness and moisture peak.

I like to use a potato masher for this, as it breaks down the fruit efficiently without turning it into a liquid. You need about 1.5 cups of mashed banana for the right texture. This step is crucial for that ultra-moist result promised in the title.

Step 2: Cream Wet Ingredients for Optimal Emulsion

In a separate bowl, whisk together the 1 cup granulated sugar, 0.5 cup vegetable oil, and 0.5 cup unsalted butter until fully combined. The butter should be melted and cooled slightly to prevent cooking the eggs when added.

Add the 2 whole large eggs one at a time, whisking vigorously after each addition until the mixture is pale and slightly thickened. This emulsification step ensures a tight crumb structure. Stir in the 2 tsp vanilla extract.

Step 3: Combine Dry and Wet for Perfect Batter

In another 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 creates a lighter texture, as noted in the ingredients list.

Gently fold the dry ingredients into the wet mixture using a spatula, alternating with the mashed bananas. Mix just until no dry streaks remain—overmixing will make the bread dense. Fold in the 0.5 cup chopped walnuts if using, reserving a few for topping.

Step 4: Bake to Golden Perfection

Pour the batter into a greased 9×5-inch loaf pan and sprinkle the reserved walnuts on top. Bake at 350°F for 55-65 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.

Check at the 50-minute mark—if the top is browning too quickly, tent loosely with foil. The loaf should be deep golden brown and the edges should pull slightly away from the pan. This visual cue, combined with the toothpick test, guarantees it’s done.

Step 5: Cool Completely Before Slicing

Let the bread cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. I know it’s tempting to slice into that warm loaf, but this step prevents a gummy texture.

Once fully cooled, the bread will hold its shape and the flavors will have time to meld. The combination of oil and butter ensures a rich, moist crumb that stays tender for days. Store leftovers wrapped tightly at room temperature.

Creative Variations of banana bread recipe with oil and butter

Chocolate Chip Swirl

Add 1 cup semi-sweet chocolate chips to the batter for a melty surprise in every bite. Toss them in 1 tbsp flour first to prevent sinking. I love using Ghirardelli chips for their rich flavor and perfect melt. 💫

Nutty Delight

Swap the chopped walnuts for pecans or hazelnuts for a different crunch. Toast the nuts in a dry pan for 5 minutes at 350°F before adding to enhance their flavor and aroma.

Spiced Up Version

Add ½ tsp nutmeg and ¼ tsp cloves to the dry ingredients for a warm, aromatic twist. These spices complement the cinnamon beautifully and add depth to the loaf’s flavor profile.

Tropical Twist

Mix in ½ cup crushed pineapple and ½ cup shredded coconut for a tropical-inspired variation. Drain the pineapple well to avoid excess moisture, and use sweetened coconut flakes for added sweetness.

Healthier Option

Replace ½ cup all-purpose flour with whole wheat flour for added fiber. You can also reduce the sugar by ¼ cup without sacrificing too much sweetness, as the ripe bananas provide natural sugars.

Banana Nut Muffins

Divide the batter into a muffin tin lined with paper liners. Bake at 375°F for 20-25 minutes for individual servings. This is great for portion control and quick grab-and-go snacks. 🥖
