Banana Cake Recipe in Steamer: Light and Fluffy Texture Without a Drop of Oil

This banana cake recipe in steamer delivers a light, fluffy texture without oil—perfect for health-conscious bakers who crave moist, tender cake. The steaming method preserves natural moisture while creating a delicate crumb that traditional baking can't match. I developed this version after struggling to find a cake that stayed soft for days without drying out or requiring butter.

What sets this recipe apart is the steaming technique, which replaces baking entirely. The batter—made with mashed bananas, eggs, and just enough flour for structure—steams to perfection in 30 minutes, yielding a cake with a gentle rise and no dense center. No butter, no oil, and no heavy crust mean each slice is lighter than conventional banana cakes yet just as satisfying.

The result is a golden, domed cake with a velvety interior that stays moist for days. The natural sweetness of bananas shines through without overpowering, making it ideal for breakfast or afternoon tea. Dust with powdered sugar or serve with a dollop of Greek yogurt for extra brightness.

This method works equally well for single servings (using small steamer baskets) or feeding a crowd. The steamer approach also eliminates the need for greasing pans or measuring oil, simplifying prep without sacrificing flavor. Ready to try a cake that's as healthy as it is delicious?

Ingredients for banana cake recipe in steamer

Bananas, eggs, and flour create this steamed cake's delicate crumb without oil or butter.

The bananas are non-negotiable—overripe with brown speckles yields the sweetest, most flavorful cake. Look for organic bananas at Whole Foods or your local farmers market for better texture. I always use 2 cups mashed (about 4 medium bananas), but if you're short, blend them with a splash of almond milk to reach the same volume. The flour should be all-purpose, not self-rising—the baking powder and soda handle all the leavening here. For the almond milk, Silk brand works best as it's thin enough to blend smoothly without altering the batter's consistency.

No almond milk? Oat milk or light coconut milk work in a pinch, but avoid anything too thick like cashew milk. Short on vanilla? Almond extract at half the amount gives a similar depth. The baking powder and soda are critical—Diamond Crystal is my go-to brand as it's aluminum-free and reacts predictably. If you're using a steamer basket, line it with parchment paper to prevent sticking, especially since this batter lacks the fat that typically keeps cakes from clinging. The lemon juice might seem like an afterthought, but it brightens the entire cake—don't skip it.

Store the cake in an airtight container at room temperature for up to 3 days, though it's best enjoyed within 24 hours of steaming. For longer storage, wrap tightly in plastic and refrigerate for up to 5 days, though the texture becomes slightly denser. Freezing isn't recommended as the steamed cake's delicate crumb absorbs moisture over time. To reheat, steam for 5 minutes—this restores the tender texture without drying it out. The powdered sugar should be added just before serving to prevent clumping.

Step-by-step instructions for banana cake in steamer

This method delivers a perfectly moist, fluffy cake with tender layers—all without traditional baking.

In a medium bowl, mash the 2 cups ripe bananas until completely smooth with no visible lumps. I use a potato masher for this—it's gentle enough to avoid over-mixing while ensuring a uniform texture. Add the 0.5 cup unsweetened almond milk and 1 tbsp lemon juice to the mashed bananas and whisk vigorously for 30 seconds. This creates a light, airy base that will help the cake rise beautifully in the steamer.

In a separate bowl, whisk together the 2 whole large eggs until frothy but not fully emulsified—you want soft peaks, not stiff meringue. Gradually pour the egg mixture into the banana-almond mixture while whisking continuously. This step is crucial for incorporating air, which will translate to a light, fluffy texture in the final cake. The mixture should be smooth and slightly thickened but still pourable.

In a large mixing bowl, sift together the 1.5 cups all-purpose flour, 0.75 cup granulated sugar, 1 tsp baking powder, 0.5 tsp baking soda, and 0.25 tsp salt. I always sift dry ingredients when making cakes—it prevents lumps and ensures even distribution throughout the batter. Make a well in the center of the dry ingredients and pour in the banana-almond mixture.

Using a spatula, gently fold the wet ingredients into the dry ingredients just until combined. Avoid overmixing—you should still see small streaks of flour in the batter. This careful folding preserves the air incorporated earlier, which is essential for that signature steamed cake lightness. Once combined, add the 1 tsp vanilla extract and fold it in until just distributed.

Line a 6-inch round cake pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the parchment with a thin layer of vegetable oil to prevent sticking. Pour the prepared batter into the pan and smooth the top with a spatula. Tap the pan gently on the counter 2-3 times to eliminate any air bubbles that may have formed during mixing.

Place the pan in the center of your steamer basket, ensuring it sits on the rack rather than touching the bottom. The pan should be elevated to allow steam to circulate evenly around the cake. Fill the steamer with 2-3 inches of water and bring to a boil over medium-high heat. Once boiling, cover the steamer with the lid and reduce heat to medium-low to maintain a gentle, steady steam.

Steam the cake for 45-50 minutes. The cake is done when a toothpick inserted into the center comes out clean and the edges begin to pull away slightly from the pan. I check for doneness at the 40-minute mark—this is the moment that matters. The cake should be golden at the edges but still tender in the center, with a slight bounce when pressed gently.

Remove the cake from the steamer and let it cool in the pan for 10 minutes. This brief resting period helps the cake set slightly before you transfer it to a wire rack to cool completely. Once cooled, dust the top generously with 0.25 cup powdered sugar using a fine-mesh sieve. This step adds a delicate sweetness and professional finish to your cake.

Troubleshooting your banana cake recipe in steamer

Batter Too Thin?

If your batter looks too runny, add 1-2 tbsp more flour and fold gently until just combined. Overmixing can make the cake dense, so stir only until the flour disappears. I’ve found that using Whole Foods organic flour absorbs slightly differently than store brands—adjust gradually. 🌾

Cake Not Rising?

Check your baking powder and soda first—they lose potency over time. Replace with fresh Diamond Crystal brands. Also, ensure your steamer has a tight seal and water hasn’t evaporated during steaming. A 1-inch water level is ideal for consistent steam pressure.

Undercooked Center?

Steam for an extra 5-10 minutes if the center feels soft. The cake should spring back slightly when pressed. If it’s still underdone, tent with foil and steam another 5 minutes—this prevents over-browning while ensuring full doneness. 🔥

Dry or Crumbly Texture?

This usually means oversteaming or insufficient moisture. Reduce steaming time by 5 minutes next time and add 1 tbsp almond milk to the batter. The bananas must be ripe—underripe ones add less natural sweetness and moisture. Always use 2 cups mashed for the best texture.

Sticking to Pan?

Grease the parchment paper with a thin layer of vegetable oil before pouring batter. If it still sticks, try a nonstick baking spray like Pam on the parchment. Avoid overgreasing—excess oil can make the cake greasy. A 6-inch pan works best; larger pans may require longer steaming.

Uneven Top?

Smooth the batter with a spatula before steaming, then tap the pan gently on the counter to release air bubbles. If the top collapses, your cake may have oversteamed. Next time, check for doneness at 40 minutes and remove promptly when a toothpick comes out clean. 💡
