Recipe Information

• Prep Time: 5 minutes
• Cook Time: 3–5 minutes
• Total Time: 10 minutes
• Servings: 2–4, depending on mug size and portion
• Cooking Method: Microwave
• Category: Healthy Dessert, Breakfast, Snack
• Cuisine: Homemade

Ingredients

• 4 ripe bananas
• 1 large egg
• ⅓ cup (80 ml) milk
• 1 cup (100 g) rolled oats
• ½ teaspoon ground cinnamon (optional)
• ½ teaspoon vanilla extract (optional)
• ½ teaspoon baking powder (optional, for a lighter texture)
• A pinch of salt

Instructions

Step 1: Prepare the Bananas

Peel the four ripe bananas and place them in a large mixing bowl. Choose bananas with plenty of brown spots because they are naturally sweeter and easier to mash.

Using a fork, mash the bananas until they become a smooth puree. A few small banana pieces are perfectly fine if you enjoy a little texture.

Step 2: Add the Wet Ingredients

Add the egg and milk to the mashed bananas. Whisk everything together until well combined.

Add vanilla extract if desired. It gives the dessert a lovely homemade aroma and enhances the natural banana flavour.

Step 3: Add the Oats

Add the rolled oats, cinnamon, baking powder, and a pinch of salt.

Stir thoroughly until all the oats are coated with the banana mixture. Let the batter rest for approximately 5 minutes so the oats can absorb some of the liquid.

For a smoother, more cake-like texture, blend the mixture until almost completely smooth.

Step 4: Prepare Your Mug

Lightly grease a large microwave-safe mug or divide the mixture between two or more microwave-safe mugs.

Do not fill the mugs more than halfway to allow room for the cake to rise.

Step 5: Cook the Mug Cake

Microwave on HIGH for approximately 2–4 minutes, depending on the microwave’s power and the size of the mug.

Check the centre after 2 minutes. Continue cooking in 30-second intervals until the centre is set.

If using several mugs, cook them separately for more even results.

Step 6: Let It Rest

Carefully remove the mug from the microwave because it may be hot.

Allow the cake to rest for 2–3 minutes. This helps the texture settle and makes it easier to enjoy.

Step 7: Add Your Favourite Toppings

Enjoy it warm straight from the mug or add your favourite toppings, such as:

• Fresh banana slices
• A sprinkle of cinnamon
• Chopped walnuts
• Unsweetened shredded coconut
• A spoonful of plain Greek yoghurt
• A few fresh berries

Enjoy your naturally sweet banana oatmeal dessert!

Notes

1. Use very ripe bananas for the sweetest flavour.
2. Rolled oats work particularly well for this recipe.
3. Certified gluten-free oats are essential if you need to avoid gluten.
4. Unsweetened milk helps keep the recipe free from added sugar.
5. The batter should be thick but spoonable.
6. Microwave cooking times vary, so check frequently.
7. This recipe contains natural sugars from bananas and is not sugar-free in the sense of containing zero sugar.

Tips for the Best Results

• Choose Ripe Bananas: Brown-spotted bananas provide more natural sweetness.
• Blend for a Smooth Cake: Blending the oats creates a softer, more traditional cake-like consistency.
• Don’t Overcook: Too much microwave time can make the cake dry and rubbery.
• Use a Large Mug: The mixture expands while cooking.
• Add Cinnamon: Cinnamon complements the banana flavour beautifully.
• Make It More Filling: Serve with plain Greek yoghurt for additional protein.
• Check Your Oats: Always choose certified gluten-free oats if preparing this recipe for someone with celiac disease or gluten sensitivity.
