Desserts
This banana cake with coconut milk delivers the perfect balance of tropical moisture and nutty crunch—no dry crumbs in sight. 🌴 The secret lies in replacing traditional dairy with coconut milk, which creates a tender, almost fudgy texture while adding subtle sweetness that complements the ripe bananas. I developed this recipe after years of baking banana cakes that always turned out too dense or dry, and this version finally cracked the code.
The coconut milk doesn’t just enhance flavor—it transforms the cake’s structure. While regular milk can leave cakes slightly heavy, coconut milk keeps this one light yet rich, with a delicate crumb that’s almost melt-in-your-mouth. The recipe also incorporates toasted coconut flakes for texture, giving each bite a satisfying contrast between soft cake and crispy bits. It’s the kind of dessert that feels indulgent without being overly sweet.
What makes this recipe stand out is its versatility. Whether you’re baking for a tropical-themed party or simply craving a comforting treat, this cake delivers. The coconut milk works especially well with overripe bananas, turning them into a naturally sweet base. Pair it with coconut whipped cream or fresh mango slices for a dessert that tastes like a vacation in every bite.
Ready in just one hour from start to finish, this cake is perfect for weeknight desserts or special occasions. The instructions are straightforward, and the ingredients are simple—no fancy techniques required. Let’s get baking!
Ingredients for banana cake with coconut milk
Eight simple ingredients transform into a tropical banana cake with melt-in-your-mouth texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, approximately 3 medium bananas |
| All-Purpose Flour 🌾 | 2 cups | Sifted for even texture |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Coconut Milk 🥥 | 1 can | Full-fat, 13.5 oz can |
| Unsweetened Applesauce 🍎 | ½ cup | For moisture and fat substitute |
| Vanilla Extract 🌿 | 1 tbsp | Pure vanilla preferred |
| Baking Soda 🧂 | 1 tsp | Pure baking soda |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Toasted Unsweetened Coconut Flakes 🥥 | 1 cup | Plus extra for topping |
| Vegetable Oil 🫒 | ½ cup | Light or canola oil |
| Almond Extract 🌿 | ¼ tsp | Optional, for nutty depth |
| Mango Puree 🥭 | ¼ cup | Optional, for tropical flavor |
The coconut milk is non-negotiable here—it’s what gives this cake its signature moisture and subtle sweetness. Full-fat canned coconut milk (like Thai Kitchen or Goya) works best, but if you only have light coconut milk, add an extra tablespoon of applesauce to compensate. For the bananas, ripe is key—they should be soft enough to mash with a fork but not brown or mushy. I always grab extra bananas and let them sit on the counter for a day to ripen fully. The coconut flakes? Toast them in a dry pan for 3-4 minutes until golden—they’ll add that satisfying crunch. If you're feeling adventurous, swap half the flour for almond flour for a nutty twist.
No coconut milk? Full-fat coconut cream works in a pinch, but reduce the applesauce by 2 tablespoons. Short on bananas? Substitute with mashed sweet potato or pumpkin puree (use the same amount), though the flavor will shift slightly. The almond extract is optional but adds a lovely depth—if you skip it, a splash of almond milk in the coconut milk mixture works too. For the sugar, brown sugar adds moisture, but white sugar keeps the cake lighter. The mango puree is a game-changer if you love tropical flavors; if you can’t find it, blend fresh mango or use more banana puree. Always sift the flour to avoid dense cake, and don’t overmix the batter—just combine until just combined.
This cake keeps well for 4-5 days in an airtight container at room temperature, though it’s best enjoyed fresh. For longer storage, wrap tightly and refrigerate for up to 1 week. The coconut flakes on top stay crisp for 2 days, so add them just before serving. Leftovers reheat beautifully—microwave for 20 seconds or warm in a 300°F oven for 10 minutes to restore moisture. I like to slice it into thick pieces for a decadent dessert experience, and it pairs perfectly with coconut whipped cream or a dollop of Greek yogurt for extra protein. The cake actually tastes better the next day as the flavors meld.
Why You'll Love This Recipe
- No Mash Needed: I swear by this trick—just mash those bananas right in the bowl with the flour. No strainers, no extra bowls, and the texture stays light without overmixing. That applesauce swap? It keeps things moist without tasting like pie filling.
- Tropical Twist: The coconut milk makes this cake taste like a vacation in every bite—creamy, slightly sweet, but not cloying. Honestly, I’ve never had a banana cake that didn’t taste like a sad, dry sponge until I added this. The sugar caramelizes just enough to give it that golden, buttery crust.
- Breakfast or Dessert: Serve it warm with a scoop of vanilla ice cream for dinner, or pack slices in lunchboxes the next day. My kids ask for it after school, but I secretly love it more as a midnight snack—no judgment. The applesauce keeps it light enough for breakfast, but the coconut milk makes it feel indulgent.
- Pantry Magic: I’ve made this three times with whatever bananas were spotted and whatever sugar was on sale. No fancy ingredients, no last-minute grocery runs. The coconut milk adds richness without breaking the bank, and leftovers? They actually get better the next day—moist, not gummy.
Step-by-step instructions for banana cake with coconut milk
Master this tropical twist on classic banana cake with rich coconut milk and nutty crunch.
👨🍳 Step 1: Prep the Wet Ingredients
In a medium bowl, mash the 2 cups ripe bananas until completely smooth with no lumps—this ensures even distribution in the batter. Stir in the 1 can coconut milk, 0.5 cup unsweetened applesauce, and 0.5 cup vegetable oil until fully combined. The mixture should be thick but pourable, with a creamy coconut aroma.
Add the 1 cup granulated sugar, 1 tbsp vanilla extract, 0.25 tsp almond extract, and 0.25 cup mango puree (if using). Mix well until the sugar dissolves completely. Here's the thing—this step creates the cake's signature moisture. The coconut milk and applesauce replace butter while keeping it tender, and the mango puree adds subtle tropical depth that pairs perfectly with the bananas.
👨🍳 Step 2: Combine Dry Ingredients
In a separate large bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking soda, and 0.5 tsp salt. Sift the flour first for an even texture—this prevents dense spots in your cake. Make a well in the center and pour in the wet ingredients. Gently fold with a spatula just until combined, being careful not to overmix.
Here's where it gets fun—fold in 1 cup toasted unsweetened coconut flakes by hand. You want them distributed evenly throughout the batter. The toasted coconut adds both texture and flavor, giving each bite that satisfying crunch against the moist cake. If you're using a stand mixer, switch to low speed and mix just until the coconut flakes are incorporated.
🔥 Step 3: Bake to Golden Perfection
Preheat your oven to 350°F and grease an 8-inch round cake pan or line it with parchment paper. Pour the batter into the prepared pan and smooth the top. Sprinkle any remaining coconut flakes on top for extra crunch. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean and the edges are golden brown.
Don't walk away during the last 10 minutes—ovens vary, and you want that perfect balance of moist interior and slightly crisp exterior. The cake should pull away from the sides of the pan easily when done. If the top browns too quickly, tent loosely with foil after 25 minutes to prevent over-browning while allowing the center to cook through.
⏰ Step 4: Cool and Serve
Remove the cake from the oven and let it cool in the pan for 10 minutes. Then transfer it to a wire rack to cool completely. This resting period is crucial—it allows the cake to set properly and prevents it from falling apart when slicing. The contrast between the warm, moist cake and the cool coconut crunch is what makes this recipe special.
For serving, slice into 8 equal pieces and enjoy at room temperature. The cake's texture should be tender yet slightly dense from the coconut milk, with pockets of moist banana flavor throughout. The toasted coconut flakes add a delightful contrast that keeps each bite interesting. Store leftovers in an airtight container for up to 3 days or freeze for longer storage.
Pro Tips For Making Banana Cake With Coconut Milk
- Mash Bananas Well: I learned this the hard way—lumpy banana puree makes for a dense, uneven cake. Use a fork first to break them up, then press through a fine-mesh sieve or mash against the side of the bowl until completely smooth. This also removes excess starch that can make the cake gummy.
- Preheat Pan Properly: Coconut milk adds moisture, so a cold pan will cause the cake to sink in the middle. Heat your 9-inch round or 8x8-inch square pan for 5 minutes before pouring the batter—this helps the edges set faster and keeps the texture light.
- Don’t Overmix the Batter: The second you add flour, stop stirring. Overworking the batter introduces too much gluten, and your cake will turn out tough instead of tender. Fold just until combined—think "quick swirls, not a full-on workout."
- Use Full-Fat Coconut Milk: The creamier the coconut milk, the richer the flavor and the moister the crumb. Skip the light version—it won’t give the same depth, and the cake might dry out faster. Even canned full-fat works if you’re in a pinch.
Common mistakes when making this recipe
Overmixing the Batter
I’ve ruined more banana cakes than I’d like to admit by overmixing the batter—especially when folding in the coconut flakes. The moment you see streaks of flour in your wet ingredients, stop stirring immediately. Overmixing develops gluten, which makes the cake dense and tough instead of light and fluffy. The coconut milk’s natural richness can mask this slightly, but you’ll still end up with a cake that feels more like a bread than a tender dessert. 🥥
Using Unripe Bananas
Unripe bananas are the enemy of this recipe—they’re too firm and won’t mash smoothly, leaving your batter lumpy and uneven. The texture of the cake will be dry and crumbly rather than moist and fudgy. Always choose bananas that are soft enough to mash with minimal effort but not so ripe they’re brown and mushy. If you’re unsure, press your thumb into the peel: it should give slightly but not feel mushy.
Skipping the Toasting Step
Raw coconut flakes won’t provide the same satisfying crunch as toasted ones, and they’ll actually absorb moisture from the cake, making it gummy. Toasting for just 3-4 minutes until golden brings out their natural sweetness and creates that perfect textural contrast. If you’re in a rush, you can pulse them quickly in a food processor instead of toasting, but they won’t have the same depth of flavor. 🌟
Incorrect Oven Temperature
Baking at 325°F instead of the required 350°F will leave your cake underdone and gummy in the center, while 375°F can cause the top to brown too quickly before the middle is fully cooked. The coconut milk’s higher fat content means the cake needs that precise temperature to set properly. Always preheat your oven for at least 15 minutes and use an oven thermometer to confirm accuracy—many home ovens run hot or cold.
Not Greasing the Pan Properly
A cake that sticks to the pan is the worst—especially when you’re trying to slice it neatly. Grease your 8-inch round pan thoroughly with vegetable oil or butter, then line the bottom with parchment paper for extra insurance. For stubborn cakes, I even dust the parchment with a light layer of flour before pouring in the batter. If you’re using a non-stick pan, still grease it lightly to prevent any potential sticking.
Ignoring the Resting Time
Skipping the 10-minute rest in the pan before transferring to a wire rack is a common rookie mistake. This short wait lets the cake set slightly, preventing it from collapsing or falling apart when you slice it. The coconut milk’s moisture means the cake needs this extra time to firm up—otherwise, you’ll end up with a crumbly mess. Trust me, those extra minutes make all the difference in presentation and texture. ⏰

Frequently asked questions
Can I make this banana cake vegan?
Yes! Simply replace the 1 cup granulated sugar with 1 cup coconut sugar or maple syrup, and use 2 tablespoons ground flaxseed mixed with 6 tablespoons water as an egg substitute. The coconut milk and applesauce already make this recipe naturally dairy-free. The texture will be slightly denser but still moist and delicious.
Why does my cake turn out dry?
Dryness usually happens from overbaking or using unripe bananas. Always bake until a toothpick comes out clean (about 35-40 minutes at 350°F) and check at 30 minutes to avoid overcooking. For extra moisture, brush the warm cake with a simple syrup made from 0.25 cup sugar + 0.25 cup water while it cools. The coconut milk helps prevent dryness, but proper banana ripeness is key!
Can I use coconut yogurt instead of coconut milk?
Not directly—coconut yogurt is much thicker and would alter the cake's texture. However, you can blend 1 cup coconut yogurt + 0.25 cup water to mimic coconut milk's consistency. For best results, stick with full-fat canned coconut milk, which provides the perfect fat-to-moisture balance for this recipe. The yogurt version will be slightly tangier but still delicious.
How can I make this cake gluten-free?
Replace the 2 cups all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill). For extra moisture, add 1 extra tablespoon coconut milk to the batter. Gluten-free flours absorb more liquid, so don't skip this adjustment. The cake will still be tender but may have a slightly different crumb texture. Test with a small batch first!
What's the best way to store leftovers?
Wrap the cake tightly in plastic wrap or store in an airtight container at room temperature for up to 3 days. For longer storage, freeze slices for up to 3 months. To revive texture, microwave for 10-15 seconds or warm in a 300°F oven for 5 minutes. The coconut flakes stay crisp for 2 days, so add fresh ones when serving.
