Step 1: Prepare the Banana Base
Peel two of the bananas and place them in a mixing bowl. Using a fork, mash them thoroughly until they form a smooth puree. Take your time with this step; a well-mashed banana ensures a soft and even texture in the finished dessert.
Set the remaining two bananas aside. These will be sliced later and used as a natural topping.
Step 2: Combine the Wet Ingredients
Add the egg to the mashed bananas and mix until fully incorporated. Pour in the milk and stir again. The mixture should become smooth and slightly creamy.
This wet base provides structure, moisture, and richness to the dessert without the need for butter or oil.
Step 3: Add the Dry Ingredients
To the banana mixture, add the oats, baking powder, salt, and ground cinnamon. Stir thoroughly so that all ingredients are evenly distributed.
Next, add the unsweetened cocoa powder and mix well. The cocoa will give the dessert a subtle chocolate flavor without introducing added sugar.
Finally, fold in the chopped walnuts. They add texture, healthy fats, and a pleasant crunch that contrasts beautifully with the soft oat base.
Step 4: Assemble in a Mug
Lightly grease a large microwave-safe mug or small oven-safe ramekin. Pour the batter into the mug, filling it no more than three-quarters full to allow room for rising.
Slice the two reserved bananas and arrange them on top of the batter. You may press them gently into the surface. Add a few sliced strawberries on top for freshness and color.
Cooking Methods
Microwave Method (Quickest Option)
Place the mug in the microwave and cook on high for approximately 2 to 3 minutes. Cooking time may vary depending on your microwave’s power. The dessert is ready when the top looks set and a toothpick inserted into the center comes out mostly clean.
Allow it to rest for 1 to 2 minutes before eating, as it will be very hot.
Oven Method (For a Slightly Firmer Texture)
Preheat the oven to 180°C (350°F).
Place the filled ramekin on a baking tray and bake for 18 to 22 minutes, or until the center is set and lightly firm to the touch.
Let cool slightly before serving.
Texture and Flavor
This banana oat dessert has a moist, tender texture similar to baked oatmeal or a soft breakfast cake. The natural sweetness from the bananas eliminates the need for sugar, while cinnamon enhances warmth and depth. Cocoa adds a subtle richness, and walnuts provide contrast and structure. Fresh strawberries brighten the overall flavor with a mild tartness.
Serving Suggestions
Enjoy warm directly from the mug for a comforting treat.
Add a spoonful of plain Greek yogurt or unsweetened coconut yogurt for creaminess.
Sprinkle additional chopped walnuts on top for extra crunch.
Dust lightly with cinnamon before serving for enhanced aroma.
Storage Tips
If you prepare more than one serving, allow them to cool completely and store covered in the refrigerator for up to two days. Reheat gently in the microwave for 20–30 seconds before serving.
