Steamed Banana Recipe: Silky Custard Without the Oven

This steamed banana dessert delivers a silky custard texture without turning on your oven. I developed this method to capture the natural sweetness of ripe bananas while creating a smooth, pudding-like consistency.

The process requires just a few ingredients and 20 minutes of gentle steaming. The result is a warm, comforting treat that highlights the banana’s natural flavor in every creamy bite.

Ingredients for Steamed Banana

Just a handful of plant-based ingredients creates this silky, naturally sweet dessert.

The bananas are everything here. You need them at peak ripeness—deep yellow with plenty of brown speckling (the sugar content doubles as they ripen). Whole Foods or any well-stocked grocery store will carry silken tofu in the refrigerated section; Mori-Nu is a reliable brand. For coconut milk, Thai Kitchen or Native Forest full-fat cans are ideal—don’t use the carton stuff from the dairy aisle.

No silken tofu? Blend firm tofu with 2 tbsp coconut milk until smooth. Out of maple syrup? Agave or date syrup work in a pinch. The cornstarch can be swapped for arrowroot powder at one-third the amount, but don’t skip it entirely—the custard needs that structure. Cinnamon is optional, but it really complements the banana’s natural sweetness.

This keeps beautifully 3-4 days refrigerated in an airtight container. The custard thickens as it chills, so warm it slightly before serving. Freezes for up to 1 month—thaw overnight in the fridge. Always grease your molds well to prevent sticking.

Step-by-Step Instructions for Steamed Banana Custard

This method delivers a velvety texture with minimal effort and no oven required.

Step 1: Prepare the Banana Base

In a blender, combine the 4 whole ripe bananas with 12 oz silken tofu, 0.5 cup coconut milk, 3 tbsp maple syrup, and 1 tsp vanilla extract. Blend until completely smooth, scraping down the sides as needed.

The bananas should be very ripe—heavily speckled or even slightly brown—to ensure natural sweetness and easy blending. This creates the custard foundation with a rich, creamy consistency. Stop blending when no visible banana pieces remain.

Step 2: Thicken and Flavor the Custard Mixture

Transfer the banana mixture to a bowl and whisk in the 1 tbsp cornstarch, 0.5 tsp ground cinnamon, and 0.25 tsp salt. The cornstarch is crucial for achieving that silky, set texture after steaming.

Stir in the 1 tsp lemon juice last—this brightens the flavor and balances the sweetness. The mixture should be pourable but slightly thickened. Let it rest for 2-3 minutes to allow the cornstarch to hydrate fully before steaming.

Step 3: Grease and Portion for Steaming

Use the 1 tsp coconut oil to grease four ramekins or small heatproof bowls. This prevents sticking and ensures easy removal after steaming. Divide the custard mixture evenly among the prepared ramekins, filling each about ¾ full to allow for expansion.

Tap each ramekin gently on the counter to remove any air bubbles. This creates a uniform texture in the final custard. Cover each with a small piece of parchment paper to prevent water droplets from falling onto the surface during steaming.

Step 4: Steam to Silky Perfection

Bring 2 inches of water to a boil in a large pot with a steamer insert. Place the ramekins in the steamer, ensuring they don’t touch the water. Cover the pot with a tight-fitting lid and steam over medium heat for 20-25 minutes.

Check for doneness by inserting a toothpick into the center—it should come out clean with no liquid custard clinging to it. The custard will have a slight jiggle but will set fully as it cools. Be careful when removing the lid to avoid condensation dripping onto the custards.

Step 5: Cool and Serve

Remove the ramekins from the steamer and let them cool at room temperature for 10 minutes. This allows the custard to set completely. For best results, transfer to the refrigerator and chill for at least 1 hour before serving.

The texture should be smooth, creamy, and slightly firm with a delicate banana-cinnamon flavor. Serve at room temperature or chilled, optionally garnished with additional banana slices or a drizzle of maple syrup.

Common Mistakes When Making Perfect Results

Under-Ripe Bananas

Using bananas that aren’t ripe enough is the biggest mistake I see. You need those deep yellow with brown speckles for natural sweetness and smooth texture. Under-ripe bananas create a starchy, bland custard that never reaches that creamy consistency. 🍌

Skipping the Blending

Don’t rush the blending step. The mixture must be completely smooth before steaming. I blend for at least 1-2 minutes, scraping the sides, to eliminate all banana chunks. Any remaining pieces will create an uneven texture in your final dessert.

Overfilling Ramekins

Fill ramekins only ¾ full to allow for expansion during steaming. Overfilling causes spillage and messy cleanup. It also prevents the custard from setting properly, as the center may remain undercooked.

Insufficient Steaming Time

Steaming for less than 20 minutes results in a runny center. I check at 20 minutes with a toothpick—it should come out clean. If it’s still wet, cover and steam for another 3-5 minutes. Patience ensures that perfect silky texture.

Opening Lid Too Soon

Resist the urge to peek during steaming. Opening the lid releases steam and causes temperature fluctuations. This can lead to uneven cooking or condensation dripping onto your custards. I wait until the full 20 minutes have passed before checking. 💡

Skipping the Rest

Always let the custards rest for at least 10 minutes after steaming. This allows them to set fully. Serving immediately can result in a soupy texture. I often chill mine for 1 hour for the best consistency.
