Directions

1
Crack the egg into a mug and beat well with a fork until smooth and slightly frothy.
2
Add the oil, sugar, milk, and cornmeal, then stir until all ingredients are fully combined.
3
Fold in the all-purpose flour and baking powder, mixing until you have a smooth, lump-free batter.
4
Grease a second mug with oil and dust lightly with flour, then pour in the batter.
5
Microwave on full power for 3 minutes. Allow to rest for 1 minute before eating straight from the mug.

💡 Chef's Tip

Try stirring in a teaspoon of vanilla extract or a pinch of cinnamon for extra warmth. A few chocolate chips or a spoonful of peanut butter swirled in before microwaving takes it to the next level.
