Healthy Banana Oat Mug Cake with Cinnamon

Ingredients

• 1 medium ripe banana (≈100 g), mashed
• 1 large egg
• 4 tablespoons (about 40 g) fine rolled oats (quick oats)
• 1 teaspoon ground cinnamon
• 1/2 teaspoon baking powder
• 1 tablespoon honey (optional, for extra sweetness) (≈15 ml)
• 1 tablespoon milk (dairy or plant) to adjust the batter (≈15 ml)
• Pinch of salt
• 1 teaspoon oil to grease the mug (or butter) (≈5 ml)
• 1 tablespoon shredded coconut to sprinkle (optional) (≈7 g)

Instructions

1. Lightly oil a large mug (300–350 ml / 1¼–1½ cups) and set aside.
2. Mash the banana with a fork in a bowl until smooth.
3. Add the egg to the mashed banana and whisk with a fork until combined.
4. Stir in the oats, cinnamon, baking powder and a pinch of salt; add the honey if you want it sweeter.
5. Add the milk a little at a time until you have a thick, smooth batter (not too runny).
6. Pour the batter into the greased mug, sprinkle shredded coconut if using, and microwave on high for 90–120 seconds.
7. Carefully remove (the mug will be hot), let rest 1 minute, then unmold or serve straight from the mug.

Tips

• Use a very ripe banana (sweeter) to avoid adding much honey.
• Adjust microwave time for your appliance: start with 90 seconds and add 10–15 seconds if needed.
• For a firmer texture, replace 1 tablespoon of oats with oat flour.

Variations

• No-honey version: use 1 large banana and omit the honey.
• With a topping: add plain yogurt and banana slices on top after it cools.
• Baked in the oven: place in a small greased ramekin and bake at 180 °C (350 °F) for 12–15 minutes.
