Costco has done it again with its Banana Nut Loaf, a delightful addition to its bakery lineup that’s packed with rich banana flavor, a generous walnut topping, and a perfectly moist texture.
This 32-ounce loaf is not only great for breakfast or an afternoon snack but can also be elevated with simple serving ideas. Read on for a detailed review, nutritional information, and tips on storing leftovers.
First Impressions & Taste Test
Right out of the package, the Banana Nut Loaf makes a strong impression with its golden-brown crust and an abundance of chopped walnuts on top. The loaf has a firm yet tender texture, making it easy to slice without crumbling.
The flavor is spot-on—rich banana taste with just the right amount of sweetness. It doesn’t feel overly sugary, allowing the natural banana flavor to shine through. The walnuts add a satisfying crunch, making every bite an enjoyable mix of soft and crunchy textures.
One of the best ways to enjoy this loaf is heated in the microwave and slathered with butter. Warming it up enhances the banana flavor, while the butter adds an indulgent richness that takes it to another level!

Cost of the Banana Nut Loaf
The loaf is Item Number 1759778 and is located in the bakery along with the croissants, muffins and artisan breads.
The 32 ounce loaf cost $7.99 in February of 2025. The $7.99 price is a dollar higher than what it would cost you to buy an 8 pack of the new Costco Muffins.
At this price the loaf is something that wouldn’t mind buying to take to work and put out in the coffee break room for everyone to enjoy.

The label lists the ingredients for the loaf as:
- Bleached Enriched Flour
- Sugar

I was glad to see that the ingredient list looked like real food and was not packed with preservatives and chemicals!
How to Store & Freeze Costco’s Banana Nut Loaf
If you’re not planning to finish the entire loaf within a few days, proper storage is essential to keep it fresh. Here are some tips:
Short-Term Storage (1-3 Days)
- Keep the loaf in its original packaging or wrap it in plastic wrap.
- Store at room temperature in a cool, dry place.
- Avoid refrigeration, as it can dry out the bread.
Long-Term Freezing (Up to 3 Months)
- Slice the loaf before freezing to make it easier to defrost individual portions.
- Wrap each slice or section tightly in plastic wrap, followed by a layer of aluminum foil or a freezer-safe bag.
- To thaw, leave a slice at room temperature for 30 minutes or microwave it for about 20-30 seconds.
By following these steps, you can enjoy the Costco Banana Nut Loaf for weeks to come!
