Lemon Mug Cake Step-by-Step Cooking Instructions

Step 1: Prepare the Mug

Use a microwave-safe mug (at least 12 oz) to prevent overflow. Lightly grease the inside with oil or butter.

Step 2: Mix the Dry Ingredients

In your mug, combine flour, sugar, baking powder, and salt. Stir well to ensure even distribution.

Step 3: Add the Wet Ingredients

Pour in the milk, oil, lemon juice, vanilla extract, and lemon zest. Mix everything thoroughly until you get a smooth batter.

Step 4: Microwave the Cake

Microwave on high for 60–90 seconds. Start with 60 seconds and check—if the center is still wet, microwave in 10-second intervals until cooked through.

Step 5: Let it Rest and Enjoy!

Allow the cake to sit for a minute before digging in. This helps set the texture and prevents burns.

Common Mistakes to Avoid While Preparing Lemon Mug Cake

• Using too small a mug: The batter needs room to rise.
• Overcooking: Microwaves vary, so always check at the 60-second mark.
• Skipping the mixing step: Unevenly mixed batter leads to inconsistent texture.
