Ripe bananas are non-negotiable hereāthey're the heart of this cake. Look for bananas with brown spots when you're shopping, and mash them well to avoid lumps. The butter matters tooāfull-fat, unsalted gives that rich, velvety texture. I always grab mine from Trader Joe's or the bakery section at Whole Foods for the best quality. For the spices, Penzeys has the best ground cinnamon and nutmeg, but the grocery store stuff works fine if it's fresh. Pandan extract? Asian markets carry itāit's what gives this cake that signature Singaporean aroma.
No ripe bananas? Cook 2 regular bananas in a microwave for 2 minutes to soften them first. Short on walnuts? Pecans or almonds work too, but toast them first for better flavor. The oats can be skipped if you're out, but the streusel will be less crunchy. For the sugars, light brown sugar in the streusel gives that caramelized biteādon't substitute white. The vanilla extract should be pure; imitation just doesn't cut it here. And if you can't find pandan extract, vanilla bean paste at double the amount adds a nice floral note.
This cake keeps well for 3 days at room temperature, wrapped tightly. For longer storage, slice it and freeze between parchment paper for up to 3 months. I like to make a double batchāone for immediate family, one to freeze for when cravings hit. The streusel stays crispy for days if you store it separately, which is perfect for topping yogurt or ice cream later. And trust me, it reheats beautifullyājust a few seconds in the microwave to bring back that fresh-from-the-oven warmth.

Step-by-step instructions for banana butter cake with Singaporean flair
Here's how to bake a cake that's perfectly moist inside and topped with a fragrant, nutty streusel.
šØāš³ Step 1: Prep the Banana Butter Base
Preheat your oven to 350Ā°F and grease an 8-inch round cake pan or line it with parchment paper. In a large mixing bowl, mash the 1.5 cups ripe bananas until completely smooth with no lumps remaining. This ensures your cake will be tender and moist.
Add the 1 cup melted unsalted butter and mix until fully combined. Then whisk in the 2 cups granulated sugar, 2 whole large eggs, 1 tsp vanilla extract, and 0.5 tsp pandan extract. The pandan gives that signature Singaporean flavorāit's floral and slightly vanilla-like. Mix until everything is well incorporated and the batter looks smooth.
šØāš³ Step 2: Combine Dry Ingredients
In a separate bowl, sift together the 2 cups all-purpose flour, 1 tsp baking soda, 0.5 tsp salt, 2 tsp ground cinnamon, and 0.5 tsp ground nutmeg. The cinnamon and nutmeg are key for that warm spice flavor that pairs perfectly with banana.
Gradually add the dry ingredients to the banana mixture, mixing just until combined. Be careful not to overmixāstop as soon as the flour disappears. The batter should be thick but pourable. This is where the magic happensāthe perfect balance of moisture and structure for that classic banana cake texture.
š„ Step 3: Make the Streusel Topping
In a medium bowl, combine the 0.5 cup light brown sugar, 0.5 cup old-fashioned rolled oats, 0.5 cup chopped walnuts, and 1 tbsp all-purpose flour from the original 2 cups. The walnuts add a nice crunch that contrasts beautifully with the soft cake.
Use your fingers to rub the mixture between your palms until it reaches a crumbly consistency. This creates those perfect little clusters that will caramelize beautifully on top. The streusel should look like coarse sand with visible walnut piecesāthis is what gives the cake its signature texture contrast.
š„ Step 4: Assemble and Bake
Pour half of the banana batter into your prepared cake pan. Then sprinkle about half of the streusel mixture evenly over the top. Repeat with the remaining batter and streusel, pressing down gently with the back of a spoon to help it stick. This layering ensures every bite has that perfect combination of moist cake and crunchy topping.
Bake for 40-45 minutes or until a toothpick inserted in the center comes out clean. The top should be golden brown with the streusel looking toasted and slightly caramelized. If you peek too early, the cake might collapseātrust the toothpick test over visual cues.
ā° Step 5: Cool and Serve
Let the cake cool in the pan for 15 minutes before transferring it to a wire rack to cool completely. This gradual cooling prevents the cake from cracking. The center should be slightly warm but firm to the touch when you're ready to serve.
Slice into wedges and serve warm or at room temperature. The contrast of the moist banana cake with the crunchy, nutty streusel is what makes this Singapore-style version so special. Store leftovers in an airtight container for up to 3 days or freeze for longer storage.
Pro Tips For Making Banana Butter Cake Recipe Singapore
- Mash Bananas Thoroughly: Skip the food processorāyour hands are better. Ripe bananas should be smooth, not chunky, or the cake will taste like you rushed. I learned this the hard way when I got lazy and ended up with a texture closer to banana bread than cake.
- Use Room-Temp Butter: Softened butter blends better with the sugars and bananas, so donāt pull it straight from the fridge. Cut it into small cubes and let it sit for 30 minutesāthis guarantees a lighter crumb. (Yes, even if youāre impatient like me.)
- Donāt Overmix the Batter: Stir just until the flour disappearsāoverworking it makes the cake dense. I used to mix until I thought it was "done," but the result was a brick, not a tender cake. Two minutes max with a spatula.
- Check Doneness Early: This cakeās center stays moist, so pull it out when the edges are golden and a toothpick comes out with a few moist crumbs, not wet batter. After burning three batches, I finally figured out: 20-25 minutes at 350Ā°F (175Ā°C) is the sweet spot.
Creative variations of these flavors
Pandan-Inspired Twist
The 0.5 tsp pandan extract in this recipe is what elevates it from classic banana cake to a Singaporean-inspired treat. This extract, made from the leaves of the pandan plant, adds a delicate floral aroma that pairs beautifully with banana and cinnamon. For a more intense flavor, you can substitute with 1 tsp vanilla bean pasteāit wonāt be identical, but it adds a similar floral depth. If you canāt find pandan extract, Asian grocery stores often carry it in small bottles or as a paste. šŗ
Coconut Streusel Swap
For a tropical twist, replace the walnuts in the streusel with Ā½ cup unsweetened shredded coconut and add 1 tbsp toasted coconut flakes. This variation keeps the crunch while introducing a coconutty aroma thatās very Singaporean. The coconut pairs perfectly with the banana flavor and adds a lovely texture contrast. Just be sure to toast the coconut firstāthis enhances its natural sweetness and prevents a soggy topping. š„„
Kaya Butter Frosting
Serve this cake with a dollop of homemade kaya butterāSingaporeās famous coconut jamāto take it to the next level. Spread a thin layer on each slice before serving for a sweet, nutty contrast. If you canāt make kaya, a light vanilla cream cheese frosting works too, but it wonāt have that authentic Singaporean touch. For a quick alternative, drizzle with melted dark chocolate and sprinkle with crushed peanuts. šÆ
Spiced Rum Infusion
Add 1 tbsp spiced rum to the batter for a boozy twist thatās especially popular in Singaporeās dessert culture. The rum enhances the banana flavor and adds warmth that complements the cinnamon and nutmeg. If youāre avoiding alcohol, substitute with 1 tbsp extra vanilla extract or Ā½ tsp almond extract for a similar depth of flavor. This variation works beautifully for celebrations or when you want to impress guests. š¹
Chocolate Chip Layers
For a fun variation, fold Ā½ cup chocolate chips into the batter before dividing it into layers. This creates pockets of melted chocolate throughout the cake, adding a rich contrast to the banana flavor. Use semi-sweet or dark chocolate chipsāavoid milk chocolate, as it can overpower the delicate spices. This version is a crowd-pleaser, especially for chocolate lovers. š«
Coconut Milk Moisture Boost
Replace Ā½ cup of the melted butter with Ā½ cup coconut milk for a lighter, more tropical cake. The coconut milk adds moisture and a subtle coconut aroma that pairs wonderfully with the pandan and banana. This variation is perfect if youāre watching your fat intake or want a lighter dessert. Just be sure to use full-fat coconut milk for the best texture. š„

Frequently asked questions
Why does your recipe use pandan extract?
The 0.5 tsp pandan extract gives this cake its signature Singaporean aromaāa delicate floral note that pairs perfectly with banana and cinnamon. It's what transforms a classic banana cake into something distinctly Singaporean while keeping the familiar sweetness. For a similar effect, try vanilla bean paste if you can't find pandan.
Can I make this cake gluten-free?
Yes, but with adjustments! Replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) and add Ā½ tsp xanthan gum to mimic gluten's structure. The streusel will need extra bindingātry adding 1 tbsp ground flaxseed mixed with 2 tbsp water to the streusel mixture.
How do I know when the cake is fully baked?
Use the toothpick test: Insert a toothpick into the centerāit should come out clean with just a few moist crumbs. The edges should pull away slightly from the pan, and the streusel should look golden brown and toasted. Never rely on visual cues alone, as the streusel can look done before the cake is fully baked.
Can I bake this in a different pan size?
Yes, but adjust baking time accordingly. For a 9-inch pan, bake 35-40 minutes (the cake will be slightly thinner). For a 6-inch pan, bake 50-55 minutes (the cake will be taller). Always use the toothpick test to confirm doneness. The streusel may need extra time to crisp up in smaller pans.
What's the best way to store leftovers?
Keep the cake in an airtight container at room temperature for up to 3 days. For longer storage, slice and freeze between parchment paper for up to 3 months. The streusel stays crispy if stored separatelyāperfect for topping yogurt or ice cream later!
