Banana Cake Recipe Singapore: Singapore-Style Spiced Banana Swirl Magic

This Singapore-style banana cake recipe delivers the soft, moist texture and subtle spice balance that makes it a beloved treat across the island. 💛 The secret lies in perfectly ripe bananas folded into a tender batter, then steamed or baked to create that signature fluffy crumb. My version keeps it authentic while making it foolproof for home bakers—no professional equipment required.

The cake's magic comes from a simple but effective technique: mixing the batter until just combined, then folding in mashed bananas and a touch of warm spices like cinnamon and cardamom. This creates those signature swirls while keeping the texture impossibly tender. The result is a cake that's rich enough to satisfy cravings but light enough to pair perfectly with a cup of Singaporean tea.

What you'll end up with is a cake that's dangerously easy to disappear in one sitting—soft, fragrant, and just sweet enough without being overpowering. The aroma alone will have everyone asking for seconds, and the texture holds up beautifully even after a day or two. This is comfort food at its finest, with just the right balance of warmth and sweetness.

Serve it warm with a dusting of powdered sugar or a drizzle of coconut cream for the full Singaporean experience. The recipe scales perfectly for gatherings, and leftovers reheat beautifully. Let's get baking!

Ingredients for banana cake recipe singapore

Perfectly ripe bananas and warm spices create this Singaporean classic's signature swirl and tender crumb.

The bananas are everything—look for ones with black spots and slightly soft to the touch. Trader Joe's often has perfect ones year-round, but Asian markets usually have the ripest selection. Cardamom is key here; Penzeys or Indian grocery stores carry the best ground versions. If you can't find it, allspice at half the amount works in a pinch. The butter should be soft enough to press with a finger but not melted—this ensures the right texture. For the coconut cream, grab the thick kind from Costco or Whole Foods—it separates beautifully.

No cardamom? Nutmeg or ginger at one-third the amount adds warmth without the same complexity. Substitute brown sugar with white sugar plus 1 tbsp molasses for depth. The baking powder is non-negotiable—Diamond Crystal is my go-to, but check your pantry first. For a lighter cake, sift the flour before measuring. The bananas can be mashed by hand or with a fork—no food processor needed. And if you're worried about overmixing, fold in the bananas last to keep those signature swirls.

This cake keeps beautifully for 3 days at room temperature wrapped in foil, or 5 days in the fridge. Reheat slices in a warm oven for 10 minutes to restore that fresh-baked aroma. The powdered sugar and coconut cream are optional but transform it into the full Singaporean experience. Freeze portions for 3 months—just thaw at room temperature before serving. Store the coconut cream in the fridge and bring it to room temp before drizzling for the best texture.

Step-by-step instructions for Singapore-style spiced banana swirl cake

Here's how to create this aromatic, moist cake with its signature banana swirl and cardamom-spiced flavor.

Mash the 3 medium ripe bananas in a bowl until completely smooth, with no visible lumps. I like to use a fork first to break them up, then press through a fine-mesh sieve to remove any remaining fiber—this creates a silky filling that won't sink to the bottom. Set aside while you prepare the cake batter.

The bananas should be very ripe—think brown spots and soft texture. Overripe bananas add natural sweetness and prevent the cake from tasting too dry. If your bananas aren't ripe enough, place them in a paper bag with an apple overnight to speed up the ripening process.

In a large mixing bowl, combine the 1 cup unsalted butter (softened to room temperature) with the 1.5 cups granulated sugar and 0.5 cup packed brown sugar. Beat using an electric mixer on medium-high speed for 3-4 minutes until the mixture is light and fluffy, with ribbons forming when the beaters are lifted.

This creaming process incorporates air into the batter, which is crucial for that tender, airy texture Singapore-style cakes are known for. Don't rush this step—under-creaming leads to dense cake. You'll know it's ready when the mixture nearly doubles in volume and leaves clean trails when the beaters pass through.

Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 cup milk, 1 tbsp vanilla extract, 1 tbsp ground cinnamon, 0.5 tbsp ground cardamom, 1 tsp baking powder, and 0.5 tsp salt. Mix on low speed until just combined—you should still see small streaks of flour.

I always toast the cardamom pods lightly before grinding them for this recipe. The warm, slightly bitter notes complement the sweet bananas beautifully. Sift the dry ingredients together first to prevent lumps, which helps create that signature tender crumb.

Gently fold half of the batter into the mashed banana mixture until just combined. Then carefully fold this banana mixture back into the remaining batter. This creates those beautiful swirls while keeping the filling distinct. Pour the batter into a 9-inch round cake pan lined with parchment paper.

Preheat your oven to 350°F while you prepare the pan. I like to lightly grease the parchment paper with a bit of butter for easy removal. Tap the pan gently on the counter a few times to eliminate any air bubbles that might have formed during pouring.

Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean. The cake should be golden brown on top and spring back slightly when pressed gently in the center. Let it cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.

Once cooled, dust the top with 0.5 cup powdered sugar using a fine-mesh sieve. Drizzle the chilled 0.5 cup coconut cream over the top in an attractive pattern. The contrast between the warm spices and cool coconut cream makes this cake truly special. Serve slices at room temperature for the best texture and flavor combination.

Classic Singaporean Style

This version stays true to the original with its signature banana swirl and cardamom-cinnamon spice blend. The cake is baked in a 9-inch round pan for even heat distribution, creating that signature soft, moist crumb. I've found that steaming the cake for the last 10 minutes of baking adds extra tenderness—just place the pan in a steamer basket over boiling water. The powdered sugar dusting and coconut cream drizzle are non-negotiable for authenticity. 🥥

Pandan-Inspired Twist

For a fragrant variation, add 1 tbsp pandan extract (found in Asian markets) to the batter along with the vanilla. The pandan's aromatic, slightly floral notes complement the bananas beautifully. I like to use ½ cup shredded coconut in the batter for added texture. This version pairs perfectly with pandan-flavored tea for a cohesive experience. The coconut adds a lovely crunch that balances the cake's softness.

Spiced Coconut Version

Take the classic recipe up a notch by adding 1 tsp grated fresh ginger and ½ tsp ground cloves to the spice mix. For extra richness, replace ½ cup of the milk with coconut milk. This creates a more exotic, tropical flavor profile that still maintains the cake's signature tenderness. The cloves add warmth without overpowering, while the ginger brightens the banana flavor. This version is especially popular during Singapore's Hari Raya celebrations.

Chocolate Banana Fusion

For chocolate lovers, fold in ¼ cup melted dark chocolate (70% cocoa) with the banana mixture. Add ½ cup chocolate chips to the batter for pockets of melted chocolate throughout. The chocolate deepens the banana flavor while adding a luxurious contrast. I recommend using a good-quality Dutch-process cocoa powder for smoother flavor. This fusion keeps the cake's signature softness while adding a decadent twist that's hard to resist. 🍫

Steamed Banana Bread

For a less sweet, more rustic version, reduce the sugar to 1 cup total (all granulated) and add 1 tsp baking soda instead of baking powder. This creates a denser, bread-like texture that's perfect for breakfast. The steaming process makes it incredibly moist—steam for 45-50 minutes until a skewer comes out clean. Serve warm with butter and jam for a Singaporean-style breakfast treat. This version has a nuttier flavor from the reduced sugar and baking soda.

Modern Gluten-Free Adaptation

For a gluten-free version, replace the all-purpose flour with 2 cups gluten-free 1:1 baking flour (like Bob's Red Mill) plus 2 tbsp cornstarch. Add 1 extra egg to help bind the batter. The texture will be slightly denser but still moist. I've found that toasting the gluten-free flour for 5 minutes before mixing improves the flavor and structure. This version works beautifully with the same banana swirl technique and spice blend. 💪
