Ingredients for banana cake recipe with coconut flour
Eight simple ingredients transform into ultra-moist banana cake with coconut flour's nutty crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 cups | Mashed, about 3 medium bananas |
| Coconut Flour 🥥 | 1 ½ cups | Sifted, Bob's Red Mill preferred |
| Almond Milk 🥛 | 1 cup | Unsweetened, room temperature |
| Maple Syrup 🍯 | ½ cup | Pure, Grade B preferred |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For moisture and richness |
| Vanilla Extract 🌿 | 1 tbsp | Pure, high-quality preferred |
| Baking Soda 🧂 | 1 tsp | For leavening |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Ground Cinnamon 🌶️ | 1 tsp | Freshly ground preferred |
| Unsweetened Applesauce 🍎 | ½ cup | For moisture and binding |
| Flaxseed Meal 🌾 | 2 tbsp | For egg replacement |
| Water 💧 | ¼ cup | For flax egg mixture |
| Toasted Coconut Flakes 🥥 | ¼ cup | For topping (optional) |
Coconut flour is the star here—Bob's Red Mill is the gold standard, but any quality brand works. Look for vibrant white color and no off smells, which means it's fresh. The flaxseed meal is critical for that egg-like binding; ground flaxseeds from bulk bins stay fresher longer. Ripe bananas are non-negotiable—they should be soft enough to mash with a fork, almost like pudding. Trader Joe's often has perfectly ripe ones at great prices. Toast your coconut flakes lightly in a dry pan for 3-4 minutes until golden—they'll add texture and aroma to every bite.
No coconut flour? Almond flour at 1:1 ratio works, but the texture will be denser. Swap maple syrup for agave if you prefer, though maple adds deeper flavor. Short on almond milk? Oat milk or coconut milk both work well, but avoid soy milk—it can make the cake gummy. The flax egg can be prepped ahead; just mix the flaxseed meal and water, let it sit for 5 minutes, then add to your wet ingredients. Fresh cinnamon makes a noticeable difference over ground—Penzeys has excellent whole cinnamon sticks you can grind yourself.
This batter thickens as it sits, so mix everything just until combined—overmixing develops gluten and makes the cake tough. Store batter in an airtight container in the fridge for up to 24 hours—it actually tastes better the next day as the flavors meld. Baked cake keeps 4 days wrapped at room temperature or 1 week refrigerated. For longer storage, slice and freeze portions for up to 3 months. The coconut flakes on top stay crisp for about 2 days, so add them fresh if you're saving leftovers.

Step-by-step instructions for banana cake with coconut flour
Here's how to create a perfectly moist banana cake with nutty coconut crunch—no dry bites here.
👨🍳 Step 1: Prepare the Flax Egg and Combine Wet Ingredients
Start by making the flax egg: In a small bowl, whisk together the 2 tablespoons flaxseed meal and ¼ cup water. Let it sit for 5 minutes until it thickens into a gel-like consistency—this is your egg substitute. Meanwhile, in a large mixing bowl, mash the 2 cups ripe bananas until completely smooth with no lumps.
Add the 1 cup almond milk, ½ cup maple syrup, ½ cup extra-virgin olive oil, 1 tablespoon vanilla extract, and the flax egg mixture to the bananas. Stir well until fully combined. The batter should be thick but pourable—this is key for that ultra-moist texture. I like to use a hand mixer here for about 30 seconds to ensure everything's evenly incorporated.
👨🍳 Step 2: Mix Dry Ingredients and Combine
In a separate medium bowl, sift together the 1½ cups coconut flour, 1 teaspoon baking soda, ½ teaspoon salt, and 1 teaspoon ground cinnamon. Sifting prevents clumps and ensures even distribution of leavening agents. Gently fold this dry mixture into your wet ingredients using a spatula, mixing just until combined—overmixing develops gluten and can make the cake dense.
Add the ½ cup unsweetened applesauce and stir again until smooth. The applesauce adds moisture and helps bind the coconut flour, which absorbs liquid differently than regular flour. You'll notice the batter is thick—this is normal with coconut flour. If it seems too stiff, add 1-2 tablespoons almond milk to reach a spreadable consistency.
🔥 Step 3: Bake Until Golden and Springy
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 with a spatula. For extra nutty crunch, sprinkle the ¼ cup toasted coconut flakes evenly over the top—press them in lightly so they stick.
Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean and the edges are golden brown. Coconut flour cakes bake faster than traditional flour cakes, so keep an eye on them after 25 minutes. The cake is done when it springs back slightly when touched in the center—this ensures it's fully set but still moist.
⏰ Step 4: Cool and Serve for Maximum Moisture
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. Here's the thing—coconut flour cakes are best served at room temperature, not warm. The cooling process allows the coconut flour to fully absorb the moisture, resulting in that ultra-moist texture you're after.
Slice when completely cool and serve with a dollop of coconut whipped cream or a drizzle of extra maple syrup. The cake should be tender with a slight crumb, not crumbly or dry. Store leftovers in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days. The coconut flavor actually improves slightly over time!
Pro Tips For Making Banana Cake Recipe With Coconut Flour
- Mix the coconut flour first: Coconut flour absorbs liquid like a sponge—don’t just toss it in dry. Whisk it with the almond milk and olive oil for at least 5 minutes before adding anything else. I learned this the hard way when my first batch turned out dense and gluey.
- Use spotty ripe bananas: Blackened spots? Good. The darker the better. Overripe bananas with brown speckles add natural sweetness and moisture, cutting down on how much maple syrup you’ll need. I was skeptical until I tried it—now I save the slightly green ones for smoothies.
- Don’t overmix the batter: This isn’t pancake batter. Once you fold in the mashed bananas, mix just until combined—coconut flour cakes have a tendency to get gummy if you work it too hard. A few lumps are fine; they’ll bake out.
- Bake at 325°F, not 350°F: Coconut flour cakes rise slower and need steady heat to avoid cracking. I used to blast the oven at 350°F and ended up with a domed, uneven top. Lower heat means even baking and a tender crumb—trust the process.
Storing and reheating your banana cake recipe with coconut flour
Room-Temp Storage
This cake stays fresh for 3 days at room temperature when wrapped tightly in plastic wrap or stored in an airtight container. The coconut flour's natural moisture retention helps preserve its ultra-tender texture. I like using glass containers with silicone lids—they keep the cake from drying out while letting me see the layers. Place it on a wire rack first to prevent sogginess from condensation. 🌿
Fridge Preservation
For longer storage, refrigerate for up to 5 days in an airtight container. The cold actually enhances the coconut flavor while maintaining moisture. Let slices sit at room temperature for 10-15 minutes before serving—they'll be firmer straight from the fridge, but the texture softens beautifully. I recommend slicing before storing to maintain that perfect crumb.
Freezing for Later
Slice the cake before freezing for best results. Wrap individual portions in plastic wrap, then place them in a freezer bag with all air removed. This method prevents freezer burn and keeps the texture intact for up to 3 months. Thaw overnight in the fridge—microwaving can make coconut flour cakes dry out. The toasted coconut flakes stay crisp even after freezing, adding a delightful texture contrast. ❄️
Reheating Secrets
For room-temperature cake, no reheating is needed—just slice and serve. If you prefer warm cake, use the oven method: Wrap slices in aluminum foil and warm at 300°F for 8-10 minutes. The foil prevents drying while gently reheating. For microwave quickness, use 20-second intervals on low power, checking between each—coconut flour cakes can dry out fast. A sprinkle of almond milk before reheating helps restore moisture.
Reviving Dry Edges
If your cake develops slightly dry edges after storage, don't toss it! Brush the top with warm maple syrup or almond milk and let it sit for 5 minutes before serving. The liquid penetrates the surface, restoring that moist, velvety texture. For extra indulgence, add a thin layer of coconut cream before reheating—it melts into the cake, making every bite rich and tender again. 💫

Frequently asked questions
Why does this banana cake use coconut flour instead of regular flour?
Coconut flour creates a naturally gluten-free, ultra-moist cake with a subtle nutty flavor that complements bananas beautifully. Unlike regular flour, it absorbs moisture differently—this recipe includes extra wet ingredients (like applesauce and olive oil) to ensure perfect texture. The result is a tender crumb with a satisfying chew, plus all the health benefits of coconut flour like fiber and healthy fats.
Can I make this recipe without flax eggs?
Yes! If you don't have flaxseed meal, try these alternatives: 1 tbsp chia seeds + 3 tbsp water (let sit 5 mins) or ¼ cup unsweetened applesauce as a binder. For best results, use a mix of both—replace half the flax egg with applesauce. The cake may be slightly denser but still delicious. Just be sure to adjust other liquids if the batter becomes too thick.
How do I know when my bananas are ripe enough?
Look for bananas with black speckles on their yellow peel—they should be soft enough to mash with gentle pressure. If they're still firm, leave them on the counter for another day. Overripe bananas (brown and mushy) work too, but the flavor becomes more caramelized. For extra sweetness, you can reduce the maple syrup by 1-2 tablespoons when using very ripe fruit.
Will this cake taste like coconut?
The coconut flavor is very subtle—think of it as a delicate nutty undertone that enhances the banana's natural sweetness. The toasted coconut flakes on top add a slight crunch and aroma, but the cake itself has a mild coconut essence that pairs beautifully with the warm banana notes. If you're sensitive to coconut taste, try reducing the coconut flour to 1 cup and adding ½ cup almond flour instead.
Can I make this cake in a different pan size?
Yes! For an 8-inch square pan, reduce baking time to 25-30 minutes. In a 9-inch round pan, bake 35-40 minutes. Always check doneness with a toothpick—coconut flour cakes bake faster than traditional cakes. If using a different shape, adjust baking time by ±5 minutes and watch closely after 20 minutes to prevent overbrowning.
