Ingredients
To make this delightful banana coconut oat cake, you’ll need the following:
- 2-3 large ripe bananas, mashed (about 1 cup or 240g)
- 1 large egg
- 1/2 cup (120 ml) milk (dairy or non-dairy)
- 1/4 cup (60 ml) vegetable oil or melted coconut oil
- 1 teaspoon vanilla extract
- 1 1/2 cups (180g) all-purpose flour
- 1 cup (90g) rolled oats (old-fashioned)
- 1/2 cup (40g) shredded unsweetened coconut
- 1/2 cup (100g) granulated sugar (or brown sugar for a richer flavor)
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- Optional: 1/2 teaspoon ground cinnamon
Ingredient Notes
- Bananas: The riper the bananas (with brown spots), the sweeter and more flavorful your cake will be. They are key for both sweetness and moisture.
- Oats: Use old-fashioned rolled oats for the best texture. Instant or quick oats can make the cake too dense.
- Coconut: Unsweetened shredded coconut is recommended to control the sweetness. If using sweetened, you might reduce the added sugar slightly.
- Milk: Any type of milk works here—dairy or a non-dairy alternative like almond or soy milk.
- Oil: Vegetable oil keeps the cake moist without adding a strong flavor. Melted coconut oil can enhance the coconut taste.
Equipment You’ll Need
- 9×5-inch (23×13 cm) loaf pan or 8×8-inch (20×20 cm) square pan
- Large mixing bowl
- Medium mixing bowl
- Whisk
- Rubber spatula
- Mashing fork or potato masher
- Measuring cups and spoons
How to Make Easy Banana Coconut Oat Cake
Follow these simple steps for a perfect banana coconut oat cake:
- Prepare Your Pan and Oven: Preheat your oven to 350°F (175°C). Grease and flour your 9×5-inch loaf pan or 8×8-inch square pan, or line with parchment paper, leaving an overhang on two sides for easy removal.
- Mash Bananas: In the large mixing bowl, mash the ripe bananas with a fork until mostly smooth but with a few small lumps remaining for texture.
-

Combine the wet ingredients until well blended. Combine Wet Ingredients: Add the egg, milk, vegetable oil (or melted coconut oil), and vanilla extract to the mashed bananas. Whisk until well combined.
- Combine Dry Ingredients: In the medium mixing bowl, whisk together the all-purpose flour, rolled oats, shredded coconut, granulated sugar, baking powder, baking soda, salt, and optional ground cinnamon until thoroughly mixed.
- Combine Wet and Dry: Pour the dry ingredient mixture into the wet ingredient mixture. Using a rubber spatula, gently fold until just combined. Be careful not to overmix; a few streaks of flour are fine. Overmixing can lead to a tough cake.
-

Pour the batter evenly into your prepared baking pan. Bake the Cake: Pour the batter evenly into your prepared baking pan and spread the top smoothly with the spatula. Bake for 30-35 minutes for a square pan or 45-55 minutes for a loaf pan, or until a wooden skewer or toothpick inserted into the center comes out clean.
- Cool: Let the cake cool in the pan on a wire rack for about 10-15 minutes before carefully lifting it out by the parchment paper overhangs (if used) or inverting onto the rack to cool completely.
Pro Tips for the Best Results
- Use Very Ripe Bananas: This is crucial for maximum sweetness and moisture. Look for bananas with plenty of brown spots on the peel.
- Don’t Overmix: Overmixing develops the gluten in the flour, which can result in a dense, tough cake. Mix until just combined.
- Measure Flour Correctly: Spoon the flour into your measuring cup and then level it off with a straight edge. Scooping directly from the bag can compact the flour, leading to too much flour and a dry cake.
- Adjust Sweetness: If your bananas aren’t extremely ripe, or if you prefer a sweeter cake, you can increase the sugar by a tablespoon or two.
- Toasting Coconut (Optional): For an extra boost of coconut flavor, lightly toast the shredded coconut in a dry skillet over medium-low heat for a few minutes until golden brown before adding it to the batter. Let it cool completely first.
- Check for Doneness: Baking times can vary depending on your oven. Always rely on the toothpick test for accuracy.
Common Mistakes to Avoid
- Using Under-Ripe Bananas: This will result in a less sweet and less flavorful cake, as well as a drier texture.
- Overmixing the Batter: As mentioned, overmixing is the enemy of a tender cake. Mix until just combined.
- Not Preparing the Pan Properly: A well-greased and floured pan (or parchment paper) ensures your cake won’t stick, making it easy to remove and preventing breakage.
- Opening the Oven Door Too Early: Resist the urge to peek during the first 20-25 minutes of baking, as this can cause the cake to sink.
Variations & Substitutions
- Add-ins: Stir in 1/2 cup of chopped walnuts, pecans, or chocolate chips for extra texture and flavor.
- Spice It Up: A pinch of nutmeg or allspice can complement the cinnamon and banana beautifully.
- Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free baking blend that contains xanthan gum. Ensure your oats are certified gluten-free.
- Vegan Version: Use a flax egg (1 tbsp ground flaxseed + 3 tbsp water, let sit for 5 minutes) instead of the chicken egg, and ensure you use a non-dairy milk.
- Different Toppings: A simple cream cheese frosting, a dusting of powdered sugar, or a drizzle of melted white chocolate can elevate this cake for dessert.
Serving Suggestions
This Easy Banana Coconut Oat Cake is wonderfully versatile:
- For Breakfast: Serve a warm slice with a dollop of Greek yogurt or a side of fresh berries for a wholesome start to your day.

- As a Snack: A great energy-boosting snack to keep you going between meals.
- Light Dessert: Enjoy it slightly warm with a scoop of vanilla ice cream or a sprinkle of toasted coconut flakes for an easy dessert.
Storage & Reheating
- Refrigerator: Store leftover cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days.
- Freezer: For longer storage, wrap individual slices or the entire cooled cake tightly in plastic wrap, then again in aluminum foil. Freeze for up to 3 months.
- Reheating: Thaw frozen cake overnight in the refrigerator or at room temperature. You can gently warm individual slices in the microwave for 15-30 seconds, or in a toaster oven until warmed through.
FAQ
Can I make this cake ahead of time?
Yes, this cake is perfect for making ahead! It tastes even better the next day as the flavors meld. Store it as directed above.
Can I use quick oats instead of rolled oats?
While possible, rolled oats provide a better texture and chewiness. Quick oats can make the cake a bit denser and less distinct in texture.
My cake is dry, what went wrong?
A dry cake is often a result of overmixing the batter or adding too much flour. Ensure you measure flour correctly and mix until just combined.
Can I add nuts to this cake?
Absolutely! Chopped walnuts or pecans are excellent additions. Fold in about 1/2 cup with the dry ingredients.
How do I know when the banana coconut oat cake is done?
Insert a wooden skewer or toothpick into the center of the cake. If it comes out clean or with a few moist crumbs attached, the cake is done. If it has wet batter, continue baking for a few more minutes.
