Banana Cake Steamed Recipe: Moist and Light Texture Without an Oven

This steamed banana cake delivers a moist, tender crumb that rivals any oven-baked version. The gentle heat preserves the fruit’s natural sweetness while creating a light, fluffy texture that melts in your mouth.

No oven required—just a steamer and 30 minutes of hands-off cooking. The result is a perfectly even bake with no dry edges, proving that some of the best desserts come from the simplest methods.

Ingredients for Banana Cake Steamed

Pantry raid time. Bananas, flour, sugar—you likely have most of this already.

The bananas need to be the ugliest ones in the bunch—black-spotted peels mean maximum sweetness and moisture. I always grab mine from Trader Joe’s or the discount rack at the grocery store. The flour should be all-purpose (no need for cake flour here), but if you’ve got it, a little cornstarch mixed in makes the crumb even lighter. For the oil, any neutral kind works—vegetable, canola, even melted coconut if you’re feeling fancy.

No eggs? Flax eggs (1 tbsp ground flax + 3 tbsp water per egg) work in a pinch, though the texture will be slightly denser. Out of bananas? Applesauce at a 1:1 ratio keeps it moist but adds its own flavor. Swap the walnuts for pecans or skip them entirely. The raisins can be left out or replaced with chocolate chips (because why not). One tip: don’t overmix—stir just until everything’s combined.

This keeps 3-4 days at room temperature in an airtight container, or 1 week in the fridge. Freeze slices wrapped in parchment for up to 3 months (thaw overnight). Honestly, it’s best the day it’s made, but leftovers toast up beautifully for breakfast.

Step-by-Step Instructions for Banana Cake Steamed

Here’s my method for achieving that perfect moist texture without ever turning on the oven.

Step 1: Prepare the Steamer and Mash the Bananas

Fill a large pot with 2-3 inches of water and bring to a simmer. You’ll need a steamer basket or rack that fits inside with at least 1 inch of clearance above the water. Meanwhile, peel the 4 whole Ripe Bananas and mash them in a large bowl until mostly smooth with just a few small lumps.

I’ve found that very ripe bananas with heavy speckling give the best flavor and natural sweetness. The steamer setup is crucial—make sure it’s stable and won’t allow water to touch your cake pan. This prevents soggy bottoms and ensures even cooking throughout.

Step 2: Combine Wet and Dry Ingredients Separately

In one bowl, whisk together the 2 whole Large Eggs, 0.5 cup Vegetable Oil, 0.75 cup Granulated Sugar, and 1 tsp Vanilla Extract until fully combined. In another bowl, sift the 2 cups All-Purpose Flour, 1 tsp Baking Powder, 0.5 tsp Baking Soda, 0.5 tsp Ground Cinnamon, and 0.25 tsp Salt together.

Sifting the flour is non-negotiable for steamed cakes—it prevents dense texture by aerating the dry ingredients. The cinnamon adds warmth that pairs beautifully with the bananas. Don’t skip the sifting; it makes a noticeable difference in the final crumb.

Step 3: Fold Everything Together with Add-Ins

Pour the wet ingredients into the dry ingredients and fold gently with a spatula until just combined—you should still see a few flour streaks. Then fold in the mashed bananas until evenly distributed. If using, gently stir in the 0.5 cup Walnuts and 0.5 cup Raisins at this point.

Here’s the thing—overmixing develops gluten and makes cakes tough. The batter should look slightly lumpy but uniform in color. If using raisins, plump them in warm water first and drain well to prevent excess moisture in your cake.

Step 4: Steam to Perfection

Pour the batter into a greased 8-inch round pan or heatproof dish that fits in your steamer. Cover the pan with foil, poking a few small holes in the top for steam to escape. Place in the steamer, cover with a lid, and steam over medium heat for 45-50 minutes.

Check for doneness by inserting a toothpick into the center—it should come out clean. The cake will pull away slightly from the edges when ready. Avoid opening the lid during steaming, as this causes temperature fluctuations that can lead to uneven cooking.

Step 5: Cool and Serve

Carefully remove the pan from the steamer and let the cake cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely. The texture improves as it cools, becoming more moist and tender.

Real talk: steamed cakes taste best at room temperature. The steam cooking method guarantees that promised moist texture without the dryness that can come from oven baking. Serve as is or with a light dusting of powdered sugar.

Creative Variations of This Recipe

Chocolate Chip Delight

Swap the raisins for ½ cup semi-sweet chocolate chips—I prefer Ghirardelli for their rich flavor. The chocolate adds pockets of melty goodness that pair perfectly with the banana’s natural sweetness. Sprinkle a few extra chips on top before steaming for a bakery-style finish. 🍫

Tropical Coconut Twist

Reduce the all-purpose flour to 1¾ cups and add ½ cup unsweetened shredded coconut to the dry ingredients. Replace the vegetable oil with coconut oil for an extra tropical note. The coconut flakes toast slightly during steaming, adding a delightful texture.

Spiced Rum Version

Add 2 tbsp dark rum to the wet ingredients and increase the ground cinnamon to 1 tsp. I love using Myers’s Rum—its molasses notes complement the bananas beautifully. A pinch of nutmeg enhances the warmth of this adult-friendly variation.

Gluten-Free Option

Replace the all-purpose flour with a 1:1 gluten-free baking blend—Bob’s Red Mill works well. Add ½ tsp xanthan gum to improve the texture. The steaming method is particularly forgiving with gluten-free flours, yielding a moister result than oven baking.

Vegan Adaptation

Use flax eggs (1 tbsp ground flax + 3 tbsp water per egg) and swap the granulated sugar for coconut sugar. Replace vegetable oil with melted coconut oil. The cake will be slightly denser but equally moist and flavorful. 🌱

Banana-Nutella Swirl

After pouring the batter into the pan, dollop 3 tbsp Nutella on top and gently swirl it in with a knife. This creates a marbled effect and pockets of hazelnut-chocolate goodness throughout the cake. Kids (and adults) go wild for this version! 💫
