Ingredients for Banana Cake Recipe in Steamer
Basic pantry staples create this tender, steamed banana cake with ease.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 2 cups | Sifted for lighter texture |
| Ripe Bananas 🍌 | 4 whole | Very ripe, heavily speckled |
| Granulated Sugar 🍚 | ¾ cup | Fine grain preferred |
| Large Eggs 🥚 | 2 whole | Room temperature for even mixing |
| Vegetable Oil 🫒 | ½ cup | Neutral flavor like canola |
| Baking Powder 🧂 | 1 tsp | Ensures proper rise |
| Baking Soda 🧂 | ½ tsp | Balances banana acidity |
| Vanilla Extract 💧 | 1 tsp | Pure extract for best flavor |
| Ground Cinnamon 🌿 | ½ tsp | Adds warmth to batter |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| Milk 🥛 | ¼ cup | Whole milk for richness |
| Chopped Walnuts 🌰 | ½ cup | Optional for crunch |
The bananas are critical here. Seek out heavily speckled, almost black bananas for maximum sweetness and moisture. Most grocery stores have these in the discounted produce section. King Arthur Flour is my go-to for all-purpose, but any unbleached variety works. The baking powder and soda must be fresh—test by dropping a pinch in hot water; it should bubble vigorously.
No ripe bananas? Bake unripe ones at 300°F for 15 minutes to soften and sweeten. Substitute applesauce for half the oil if you prefer less fat. For a dairy-free version, any plant-based milk works in place of whole milk. The walnuts can be swapped for pecans or omitted entirely if nut allergies are a concern.
This cake stays moist for 3-4 days at room temperature in an airtight container. For longer storage, freeze slices wrapped in plastic for up to 3 months. Bring to room temperature before serving to restore that delicate texture.

Step-by-Step Instructions for Banana Cake in Steamer
This method ensures a perfectly moist texture with even cooking throughout the steaming process.
Step 1: Prepare the Batter Foundation
In a large mixing bowl, cream together the 0.75 cup Granulated Sugar and 0.5 cup Vegetable Oil until the mixture lightens slightly and becomes pale yellow. This step incorporates air, which contributes to the cake’s tender crumb.
Add the 2 whole Large Eggs one at a time, mixing thoroughly after each addition. Then stir in the 1 tsp Vanilla Extract. The eggs provide structure while the vanilla enhances the banana flavor.
Step 2: Incorporate Dry Ingredients and Bananas
In a separate bowl, whisk together 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. These leavening agents work together to create a light, airy texture despite the steaming method.
Alternately add the dry ingredients and 0.25 cup Milk to the wet mixture, beginning and ending with the flour. Fold in the 4 whole Ripe Bananas, which should be well-mashed with some small lumps remaining for texture. The bananas’ natural moisture ensures the promised result.
Step 3: Add Final Touches and Prepare Steamer
Gently fold in the 0.5 cup Chopped Walnuts if using, reserving a small handful for garnish. This addition provides a pleasant contrast to the soft cake. Pour the batter into a greased heatproof cake pan that fits inside your steamer.
Tap the pan firmly on the counter 2-3 times to remove any large air bubbles. This prevents uneven pockets in the finished cake. Cover the pan loosely with aluminum foil to prevent water droplets from falling onto the cake surface.
Step 4: Steam to Perfection
Bring 2-3 inches of water to a rolling boil in your steamer base. Place the cake pan inside, ensuring the water doesn’t touch the pan’s bottom. Cover with the steamer lid and maintain a steady boil over medium heat.
Steam for 45-50 minutes until a toothpick inserted in the center comes out clean. The cake is done when it springs back lightly when touched and has pulled slightly away from the pan edges. Avoid opening the lid during the first 30 minutes to maintain consistent heat.
Step 5: Cool and Serve
Carefully remove the pan from the steamer using oven mitts. Let the cake cool in the pan for 10 minutes before transferring to a wire rack. This brief rest allows the structure to set.
Cool completely before slicing to maintain clean edges. The steaming method creates a uniquely moist crumb that improves as it sits. Serve at room temperature, garnished with the reserved chopped walnuts for added texture and visual appeal.
Pro Tips For Making Banana Cake Recipe In Steamer
- Preheat the Steamer: Make sure your steamer is already producing steady, rolling steam before the cake goes in—I learned this the hard way after my first attempt came out dense and gummy.
- Mash Bananas Well: Use a fork to mash the ripe bananas into a smooth paste, not just chunks. Sounds tedious, but it actually changes the outcome by giving the cake a uniform texture.
- Skip Cold Ingredients: Pull your eggs and oil out of the fridge at least 30 minutes before mixing. My grandmother swore by this, and she was right: room temperature ingredients blend better and rise more evenly.
- Grease the Mold: Coat your steaming mold with a thin layer of oil and dust it lightly with flour, even if it’s non-stick. I was skeptical until I tried it—no more cake sticking to the sides.

Frequently Asked Questions
Why use a steamer instead of an oven?
Steaming creates a uniquely moist, tender crumb that baking can’t match. The gentle, consistent heat prevents dryness while preserving the bananas’ natural sweetness.
Can I use overripe bananas?
The spottier the better. Overripe bananas are sweeter, mash easier, and add more moisture to your cake. Just remove any moldy spots first.
How do I prevent a soggy bottom?
Ensure your pan doesn’t touch the water. Use a heatproof cake pan that fits snugly in your steamer and cover it loosely with foil to catch condensation.
What size steamer works best?
A 10-inch diameter steamer with 2-3 inches of water depth works for most cake pans. The water should boil steadily but not touch the pan.
