Recipe Shopping List

Wondering if you have to hit the store? Here's the list of items you'll need to make this recipe. For specific amounts, please refer to the printable recipe card at the bottom of the post.

  • Cold Butter - Forms the base of the crumb topping and brings rich flavor to the cake batter. Cold butter helps create that chunky crumb texture. Salted butter works in the cake, though unsalted can be used if that's what you keep on hand.
  • Light Brown Sugar - Gives the crumb its deep sweetness and soft caramel note. It pairs especially well with banana and cinnamon.
  • All-Purpose Flour - Builds the structure for both the crumb and the cake. It's reliable, easy to find, and ideal for tender everyday baking.
  • Cinnamon - Adds warm spice to the crumb topping without taking over the banana flavor. Nutmeg can be used for a different warm note.
  • Oats - Mixed into the top crumb layer for texture and a hearty finish. Old-fashioned oats work best here.
  • Baking Powder - Helps the cake rise and keeps the crumb from feeling too dense. Fresh baking powder matters for a good lift.
  • Salt - Balances the sweetness and rounds out the banana flavor. A small amount makes a big difference in baked goods.
  • Overripe Bananas - The star ingredient. Soft, spotty bananas bring natural sweetness, moisture, and full banana flavor.
  • Sugar - Sweetens the cake batter and helps create a soft, tender crumb.
  • Eggs - Give the batter structure and richness. Room temperature eggs blend more smoothly into the mix.
  • Vanilla - Brings warmth and rounds out the sweet flavors in the cake.
  • Milk - Loosens the batter and helps keep the cake soft. Whole milk is a good fit, though lower-fat milk can work in a pinch.
  • Heavy Cream - Adds richness to the batter and forms the base of the glaze. Half-and-half can stand in for the glaze if needed.
  • Powdered Sugar - Creates a smooth, simple glaze that finishes the cake with just the right touch of sweetness.

Recipe FAQ

How Do I Store This Recipe?

Cover the pan tightly or transfer slices to an airtight container. It will keep at room temperature for up to 2 days. For longer storage, refrigerate it for up to 5 days. The crumb topping stays best when the cake is kept well covered.

How Do I Reheat It?

Warm individual slices in the microwave for about 10 to 20 seconds. You can reheat larger portions in a low oven until warmed through. Serving it warm brings back the soft cake texture and makes the glaze feel fresh again.

Can I Make It Ahead Of Time?

Yes. You can bake the cake earlier in the day or the night before. Hold the glaze until closer to serving if you want the cleanest finish. A quick warm-up before serving helps bring the texture back to its best.

Can I Change Anything In The Recipe?

You can add chopped nuts to the topping for extra crunch or bump up the cinnamon for a spicier crumb. A little nutmeg would work nicely too. If you want a lighter finish, leave off the glaze and dust the top with powdered sugar right before serving.

  3. Made this again tonight for my dinner guest.... and they loved it. No matter what this cake is always so moist. I never put the glaze on, because I find glazes too sweet and it is still the perfect banana crumb cake. I have even made it once where I substituted crushed pecans for the oats in the crumb topping.... yum!

    1. Hey Renee,

      That's awesome! Thanks so much for taking the time to stop by and let us know. I'm so glad that you and your guest enjoyed it! <3
