Plantain Cake Recipe Gluten Free: Naturally Sweet and Moist Dessert

This naturally sweet plantain cake delivers a moist texture that rivals any traditional dessert, without gluten or added sugars. The ripened plantains provide all the sweetness you need, creating a tender crumb that’s impossible to resist.

I developed this recipe after realizing how perfectly plantains can substitute for both flour and sugar. The batter comes together quickly with just a few ingredients, and the result is a cake that stays moist for days. It’s a foolproof way to use up overripe plantains.

Expect a golden cake with a soft, dense texture and subtle caramel notes from the plantains. The natural sweetness means you can enjoy it for breakfast or dessert without any guilt.

Bake it in under an hour for a treat that’s as satisfying as it is simple.

Ingredients for Plantain Cake Recipe Gluten Free

Short list. Big flavor. Naturally sweet and completely gluten-free ingredients for this cake.

The plantains are everything here. Look for the blackest, softest ones at Latin markets or well-stocked grocery stores—they’re sweeter and mash easier. Almond flour gives the best texture; Bob’s Red Mill is reliable if you’re not grinding your own. Coconut oil adds moisture (the unrefined kind smells like coconut, which works great here). If you can’t find ripe plantains, buy green ones and let them sit on the counter for a week or so.

No almond flour? Oat flour or gluten-free all-purpose works at a 1:1 swap. Out of flax eggs? Chia eggs at the same ratio or even applesauce in a pinch. Maple syrup can be skipped if your plantains are super ripe, but agave or date syrup work too. The walnuts are optional—pecans or pumpkin seeds add a nice crunch if that’s what you’ve got.

This cake stays moist for 5 days in an airtight container at room temp. Freeze slices for up to 3 months (thaw overnight before serving). It’s honestly better the next day once the flavors meld together.

Step-by-Step Instructions for Plantain Cake

Here’s my proven method for achieving that perfect moist texture with natural plantain sweetness.

Step 1: Prepare the Plantains and Wet Ingredients

Peel the 4 whole Ripe Plantains and cut them into large chunks. The blacker the skin, the sweeter and more moist your cake will be. In a blender or food processor, combine the plantain chunks with the 0.5 cup Coconut Oil, 0.25 cup Maple Syrup, 2 whole Flax Eggs, and 1 tsp Vanilla Extract.

Blend until completely smooth, stopping to scrape down the sides as needed. This puree forms the moist base of your cake. I’ve found that very ripe plantains blend more easily and create a smoother batter without any lumps.

Step 2: Combine Dry Ingredients and Create the Batter

In a large bowl, whisk together the 1.5 cups Almond Flour, 1.5 tsp Baking Powder, 1 tsp Ground Cinnamon, 0.5 tsp Sea Salt, and 0.5 tsp Baking Soda. This blend of leavening agents ensures your cake rises properly despite the density of plantain puree.

Pour the wet ingredients into the dry mixture and stir gently until just combined. Avoid overmixing. Then fold in the 0.25 cup Coconut Milk – this adds richness and maintains moisture. The batter should be thick but pourable, almost like pancake batter.

Step 3: Fold in Walnuts and Prepare the Pan

Gently fold in the 0.5 cup Chopped Walnuts with a spatula, distributing them evenly throughout the batter. These add a delightful crunch that contrasts beautifully with the moist cake texture.

Grease a 9-inch round cake pan or line it with parchment paper. I prefer parchment for easy removal. Pour the batter into the prepared pan and smooth the top with your spatula. The batter will be slightly dense, which is normal for this type of cake.

Step 4: Bake to Golden Perfection

Preheat your oven to 350°F and bake the cake for 40-45 minutes. You’ll know it’s done when a toothpick inserted in the center comes out clean and the edges start to pull away from the pan.

The top should be a deep golden brown with a slight spring when pressed lightly. Don’t be tempted to open the oven before 35 minutes – this cake needs steady heat to set properly. If the top browns too quickly, tent loosely with foil for the remaining baking time.

Step 5: Cool and Serve

Let the cake cool in the pan for 10 minutes before transferring it to a wire rack. This brief rest allows the structure to set while preventing it from becoming dry.

Cool completely before slicing – this is crucial for maintaining that promised moist texture. Serve at room temperature, where the flavors truly shine. The cake keeps well covered at room temperature for up to 3 days, though it’s best enjoyed fresh.

Storing and Reheating This Recipe

Room Temperature Storage

This cake stays wonderfully moist at room temperature for 3-4 days when stored properly. I use an airtight container or wrap it tightly in beeswax wrap to maintain freshness. The flavors actually deepen after a day, making leftovers even more delicious. 💪

Refrigerator Storage

For longer storage, refrigerate in an airtight container for up to 5 days. Let it come to room temperature before serving to restore that perfect texture. I’ve noticed the coconut oil can firm up when chilled, so that brief wait is essential.

Freezing for Later

Slice the cake and wrap individual pieces in plastic wrap, then place in a freezer-safe bag. It freezes beautifully for up to 3 months without losing moisture. This is perfect for meal prep or unexpected guests. ❄️

Reheating Methods

For the best results, warm slices in a toaster oven at 300°F for 5-7 minutes. This revives the texture without drying it out. Avoid the microwave, as it can make the cake gummy.

Serving from Frozen

Thaw overnight in the fridge or at room temperature for 2-3 hours. If you’re in a hurry, use the defrost setting on your microwave for 30-second intervals, checking frequently to avoid over-softening.
