Ingredients for Gluten Free Banana Cake

This gluten-free banana cake keeps things delightfully simpleno weird ingredients you can’t pronounce, no specialty trips to three different stores. Most of what you need is probably hanging out in your pantry right now, and the star of the show is those spotty bananas sitting on your counter that you’ve been meaning to use up.

What You’ll Need:

  • 2-3 very ripe large bananas (about 1 cup when mashed)
  • ⅔ cup granulated sugar
  • ¼ cup + 2 tablespoons neutral oil (like avocado or vegetable oil)
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1½ cups gluten-free flour blend
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • ¼ teaspoon salt

The ripeness of your bananas really matters here — we’re talking brown spots, maybe even a little soft to the touch. Those are the ones with the sweetest flavor and easiest mashing power. For the gluten-free flour, I stick with a good all-purpose blend that already has xanthan gum mixed in. Bob’s Red Mill and King Arthur both work beautifully. And here’s a tiny game-changer: use the spoon-and-level method when measuring that flour. Gluten-free flours are finicky about ratios, so don’t pack it down or you’ll end up with a dense brick instead of tender cake.

How to Make this Gluten Free Banana Cake

Start by preheating your oven to 350°F (175°C) and greasing a 9×13 inch (23×33 cm) pan — I like to give it a light dusting of gluten-free flour too, just for extra insurance against sticking.

Grab those overripe bananas and mash them up until you’ve got about 1 cup [200g] of chunky-smooth goodness. A few lumps are totally fine; they’ll add nice texture pockets to your finished cake.

In a separate bowl, whisk together your dry ingredients: 1½ cups (180g) gluten-free flour blend, 1 teaspoon (5g) baking powder, ½ teaspoon (2g) baking soda, and ¼ teaspoon (1g) salt. This step matters more than you’d think — getting everything evenly distributed now saves you from overmixing later.

Next comes the fun part: building your batter. Add ⅔ cup (140g) granulated sugar, ¼ cup + 2 tablespoons (80ml) oil, 2 large eggs, and 1 teaspoon (5ml) vanilla extract to your flour mixture. If you’re making this recipe frequently, investing in a quality stand mixer can make combining ingredients much easier and more consistent. Stir everything together until it just comes together — don’t worry about perfection here.

Then fold in those mashed bananas, mixing until everything’s combined but not overthinking it. Gluten-free batters can get gummy if you go overboard with the stirring.

Pour the whole thing into your prepared pan and slide it into the oven for about 30 minutes, checking with a toothpick around the 25-minute mark. Every oven has its own personality, so trust the toothpick test over the timer.

When it comes out clean or with just a few moist crumbs, you’re golden. Let it cool completely before cutting — I know the waiting is torture, but warm gluten-free cake tends to fall apart.

Substitutions & Variations

One of the best things about this banana cake is how flexible it’s — you can swap ingredients based on what’s hiding in your pantry or your dietary needs.

I’ve tried coconut oil instead of neutral oil — adds a subtle tropical vibe. For the sugar, brown sugar works beautifully and deepens the flavor.

Dairy-free? Use your favorite plant milk if the batter seems thick. Want chocolate chips? Fold in ½ cup. Nuts? Go for it. A good pinch of cinnamon or nutmeg transforms everything.

The gluten-free flour blend is non-negotiable though — stick with that.

What to Serve with Gluten Free Banana Cake

How do you make a good thing even better? Serve it with something that makes your taste buds do a little happy dance.

I love pairing this cake with vanilla ice cream — the contrast between warm cake and cold cream is *chef’s kiss*.

Fresh whipped cream works beautifully too, especially with a drizzle of caramel sauce.

For breakfast vibes, try it with Greek yogurt and a sprinkle of granola.

Coffee lovers, grab your favorite brew. The cake’s banana sweetness plays perfectly with bold espresso.

Sometimes simple is best — just dust with powdered sugar.

Final Thoughts

When you pull this gluten-free banana cake from the oven, you’ll realize something pretty amazing — nobody’s going to guess it’s gluten-free unless you tell them.

The texture’s perfectly tender, the banana flavor shines through, and it stays moist for days. I love how simple this recipe is. No weird ingredients or complicated steps. Just real food that happens to work for everyone at the table.
