Ingredients

For the Oatmeal Banana Cocoa Cake

• 120 g oat flakes
• 250 ml hot milk
• 2 bananas
• 2 eggs
• 4 tablespoons cocoa powder (45 g)
• 1 tablespoon baking powder
• 40 g peanuts

 

How to Make Oatmeal Banana Cocoa Cake

1. Soak the Oat Flakes

Place 120 g oat flakes in a large mixing bowl.

Pour 250 ml hot milk over the oats and stir briefly.

Leave the oat flakes to soak for 10 minutes.

During this time, the oats will absorb some of the milk and soften, preparing them for the cake batter.

 

2. Prepare the Bananas

Peel 2 bananas and place them in a separate mixing bowl.

Mash thoroughly with a fork until you have a smooth banana puree.

Ripe bananas work especially well because they are softer, easier to mash, and naturally sweeter.

3. Add the Eggs

Crack 2 eggs into the mashed bananas.

Whisk until the eggs and banana puree are thoroughly combined.

4. Add the Cocoa Powder

Add 4 tablespoons (45 g) cocoa powder.

Mix well until the cocoa is completely incorporated into the banana and egg mixture.

The batter should develop a rich, even chocolate color.

 

5. Add the Baking Powder

Add 1 tablespoon baking powder.

Stir thoroughly so the baking powder is evenly distributed.

6. Combine with the Soaked Oats

Once the oats have soaked for the full 10 minutes, combine them with the banana and cocoa mixture.

Stir until everything is evenly incorporated.

Because this cake uses oat flakes rather than conventional flour, the batter will naturally have a more textured consistency than a traditional chocolate cake batter.

 

7. Add the Peanuts

Measure 40 g peanuts and roughly chop them if necessary.

Fold the peanuts into the oatmeal batter until evenly distributed.

If you prefer some visible crunch on top, you can reserve a small portion of the peanuts and sprinkle them over the surface before baking.

8. Prepare for Baking

Preheat your oven to 180°C (356°F).

Prepare a suitable baking pan according to your preferred method.

The original recipe does not provide a specific pan size, so no pan dimensions have been added.

Transfer the batter to the prepared pan and smooth the surface evenly.

 

9. Bake

Place the cake in the preheated oven.

Bake at 180°C (356°F) for 40 minutes.

Near the end of the baking time, insert a toothpick or wooden skewer into the center to check for doneness.

It should come out without wet batter attached.

10. Cool and Serve

Remove the baked oatmeal banana cocoa cake from the oven.

Allow it to cool before removing it from the pan and slicing.

Giving an oat-based cake time to cool also allows its texture to settle, making it easier to cut into neat portions.

Serve and enjoy.

 

Tips for the Best Oatmeal Banana Cocoa Cake

Soak the oats for the full 10 minutes: This is an important step in the original recipe and helps soften the oat flakes before baking.

Choose ripe bananas: Ripe bananas are softer and naturally sweeter, making them ideal for this recipe.

Mash the bananas thoroughly: A smoother banana puree distributes more evenly throughout the batter.

Mix the cocoa well: Make sure all 45 g cocoa powder is fully incorporated so the chocolate flavor is consistent throughout the cake.

Chop the peanuts: Roughly chopped peanuts are easier to distribute through the batter.

Don’t add flour: Traditional flour isn’t required in this recipe. The 120 g oat flakes provide the grain base.

Allow the cake to cool: Cooling helps the oat-based texture settle before slicing.

 

Why You’ll Love This Recipe

This recipe requires only seven simple ingredients:

• 120 g oat flakes
• 250 ml hot milk
• 2 bananas
• 2 eggs
• 45 g cocoa powder
• 1 tablespoon baking powder
• 40 g peanuts

There’s no traditional flour and no added granulated sugar in the supplied recipe.

Cocoa transforms the banana-oat mixture into a chocolate-flavored cake, while peanuts provide a crunchy contrast to the softer interior.

It’s a straightforward recipe that doesn’t require complicated fillings, frosting, or decorating.

 

Why Soak Oatmeal in Hot Milk?

The recipe calls for soaking 120 g oat flakes in 250 ml hot milk for 10 minutes before making the cake.

This allows the oats to begin absorbing liquid and softening before they enter the oven.

Instead of grinding the oats into flour, this recipe keeps them as oat flakes and uses the soaking step to prepare their texture.

Be sure to keep the soaking time at the specified 10 minutes before continuing with the batter.

No Traditional Flour and No Added Sugar

This cake is made without traditional wheat flour. Oat flakes form the grain base instead.

It also contains no added granulated sugar.

The bananas and milk naturally contain sugars, however, so “no added sugar” is more accurate than describing the finished cake as completely sugar-free.

If avoiding added sugars is important for your diet, also check the labels of the cocoa powder and other packaged ingredients you use.

 

Serving Suggestions

This oatmeal banana cocoa cake can be served on its own or alongside:

How to Store

Allow the cake to cool completely before storing.

Place leftover slices in an airtight container and refrigerate for longer freshness.

When ready to serve, enjoy a slice chilled or allow it to sit briefly at room temperature for a softer texture.
