Costco banana bread recipe brings back the memory of a rainy afternoon when I wanted to surprise my best friend with something sweet since we couldn’t go out instead of ordering dessert I decided to bake a loaf inspired by the famous Costco banana bread so I put on my favorite playlist and started mashing ripe bananas while the smell filled the whole house and by the time she arrived the warm loaf was sitting on the counter with a golden crust and soft center ready to be shared

Every time I make this recipe it feels like a warm hug and I love how it turns ordinary ripe bananas into something magical plus I’ve discovered fun ways to make it my own by adding banana slices on top or swirling in a bit of chocolate and seeing everyone’s eyes light up when they taste that moist crumb and sweet banana flavor is the best reward it’s become one of those recipes I go back to whenever I need a quick treat or a comforting homemade gift
Ingredients
- Here’s what I use for this recipe. You can always make substitutions if you prefer!
- Ripe bananas – Provide sweetness and keep the bread moist.
- All-purpose flour – Gives structure to the bread.
- Granulated sugar – Adds sweetness and helps create a tender crumb.
- Brown sugar – Adds a deep caramel-like sweetness.
- Eggs – Bind the ingredients and add richness.
- Unsalted butter – Makes the bread soft and buttery.
- Baking soda – Helps the bread rise beautifully.
- Salt – Balances the sweetness and enhances the flavors.
- Vanilla extract – Adds warmth and depth of flavor.
- Cinnamon – Gives a subtle cozy spice.
- Banana slices (for topping) – Create an appealing finish and extra banana punch.
Tools You’ll Need
- Mixing bowls – To separate and combine wet and dry ingredients easily.
- Whisk – Perfect for mixing the wet ingredients smoothly.
- Spatula – Essential for folding without overmixing.
- Loaf pan or muffin pan – To shape the bread or mini loaves.
- Cooling rack – Prevents the bottom from getting soggy while cooling.
- Measuring cups and spoons – To keep your measurements precise and consistent.

Instructions
Step 1
I always start by preheating my oven to 350°F so it’s ready as soon as I’m done mixing.
Step 2
I mash the ripe bananas in a big bowl until they’re nice and creamy since they’re the heart of this bread.
Step 3
In a separate bowl, I whisk the flour, baking soda, salt, and cinnamon together so the dry ingredients are evenly combined.
Step 4
In another bowl, I beat the melted butter with both sugars until smooth and slightly fluffy, then I add in the eggs one by one and the vanilla extract.
Step 5
I gently fold the dry ingredients into the wet mixture using a spatula, making sure not to overmix because I want the bread to stay light and tender.
Step 6
I pour the batter into a greased loaf pan (or muffin pan if I’m making mini versions) and then top it with banana slices to make it look extra inviting.
Step 7
I bake for about 60 minutes for a loaf or 25–30 minutes for muffins, checking with a toothpick to ensure they’re done before letting them cool on a wire rack.

I like to sprinkle a little coarse sugar on top before baking to add a subtle crunch. Sometimes I also swirl in a bit of Nutella or peanut butter for a fun twist. If I have leftover slices, I toast them lightly and spread some salted butter or honey on top — it’s heavenly!
