Flourless Banana Cake in Steps

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures the cake bakes evenly.
Step 2: Prepare the Pan
Line your baking pan with parchment paper and lightly grease it with coconut oil to prevent sticking.
Step 3: Combine Wet Ingredients
In a large mixing bowl, mash the ripe bananas until smooth. Add the egg, vanilla extract, and melted coconut oil. Whisk until well combined.
Step 4: Mix Dry Ingredients
In a separate bowl, combine the cornstarch, baking powder, baking soda, ground cinnamon, ground allspice, and brown sugar. Stir to blend the dry ingredients.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry mixture to the wet ingredients, stirring gently until just combined. Avoid overmixing.
Step 6: Add Oats and Mix-ins
Fold in the old-fashioned oats and semisweet chocolate chips or nuts, whichever you prefer.
Step 7: Pour into Pan
Pour the batter into the prepared baking pan, smoothing the top with a spatula.
Step 8: Bake
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Step 9: Cool
Allow the cake to cool in the pan for about 10 minutes before transferring it to a cooling rack to cool completely.
Step 10: Frosting (Optional)
If you like, mix the powdered sugar with a little almond milk to create a simple glaze. Drizzle it over the cooled cake for a sweet touch.
Variations for Dietary Needs

- Nut-Free: Substitute almond milk with oat milk or any other non-dairy milk.
- Vegan: Replace the egg with 1/4 cup of unsweetened applesauce for binding.
- Lower Sugar: Reduce the amount of brown sugar or use a sugar substitute that measures like sugar.
- Add Protein: Mix in protein powder to boost the nutritional value without affecting texture.
Avoid These Mistakes
- Overmixing: Be careful not to overmix the batter, as it can lead to a dense cake.
- Using Unripe Bananas: Make sure your bananas are ripe to achieve the best flavor and sweetness.
- Incorrect Oven Temperature: Always preheat your oven to ensure proper baking.
- Skipping the Parchment Paper: Don’t skip lining the pan; it helps with easy removal and cleanup.
Leftovers & Meal Prep
Leftover Flourless Banana Cake can be stored at room temperature for up to 3 days or in the refrigerator for up to a week. To keep it fresh, cover it with plastic wrap or store it in an airtight container. You can also freeze slices for up to 3 months. Just make sure to wrap them well to prevent freezer burn!
This cake also makes an excellent meal prep option for breakfast. Just slice and grab a piece on your way out the door, or warm it slightly in the microwave for a comforting start to your day.
Ask & Learn
Can I use quick oats instead of old-fashioned oats?
While you can use quick oats, the texture of the cake may be slightly different. Old-fashioned oats provide a heartier texture, so if you prefer a smoother cake, quick oats are acceptable.
How do I know when the cake is done baking?
The cake is done when a toothpick inserted into the center comes out clean or with a few moist crumbs. If it’s sticky or wet, give it a few more minutes in the oven.
Can I add other flavors to the cake?
Absolutely! Feel free to experiment with different spices like nutmeg or ginger, or even add a tablespoon of cocoa powder for a chocolatey twist.
How can I make this cake more decadent?
For an extra indulgent treat, try swirling in some peanut butter or Nutella before baking, or top the cake with whipped cream and fresh fruit when serving.
