How to Make Classic Sponge Mug Cake with a Cinnamon
- Prep your mug: Lightly grease a microwave-safe mug with a bit of butter or cooking spray.
- Melt the butter: In the mug, microwave the butter for about 10 seconds until melted.
- Mix it up: Add the milk, vanilla extract, almond extract, and egg to the melted butter. Whisk until well combined.
- Add dry ingredients: Stir in the self-rising flour, granulated sugar, ground cinnamon, and a pinch of salt. Mix until the batter is smooth and lump-free.
- Microwave magic: Microwave the mug on high for 1 minute. If the cake isn’t set, give it another 10-second burst.

Tips:
- Don’t overcook: The key to a perfect mug cake is not overcooking it. Keep an eye on it and add short bursts of time if needed.
- Smooth batter: Ensure the batter is lump-free for the best texture.
Making It Extra Special
I love this with a scoop of vanilla ice cream. It’s perfect for a cozy night in. If you’re feeling fancy, add a sprinkle of fresh herbs like mint or basil. For variations, try adding nuts for crunch or using dairy-free ingredients for a vegan version.
