Ingredients List
- 4 tbsp all-purpose flour (sifted)
- 2 tbsp granulated sugar
- ¼ tsp baking powder
- 3 tbsp milk (whole or 2% recommended)
- 1 tbsp vegetable oil (or melted unsalted butter)
- 1 tbsp freshly squeezed lemon juice
- ½ tsp lemon zest (preferably organic)
- ⅛ tsp pure vanilla extract (optional, enhances lemon)
- Pinch of salt
Optional glaze:
- 2 tbsp powdered sugar
- ½ tsp lemon juice
- Drop of milk for consistency (if needed)
Step-by-Step Instructions
Prepare the Mug:
Use an 8 to 10 oz microwave-safe mug. Lightly grease the inside with a drop of oil or butter to prevent sticking.
Mix Dry Ingredients:
In the mug, whisk together flour, sugar, baking powder, and salt. Use a fork or small whisk to avoid clumping.
Add Wet Ingredients:
Stir in the milk, oil, lemon juice, lemon zest, and vanilla extract (if using). Mix thoroughly until the batter is smooth and lump-free. Scrape the sides to incorporate all ingredients.
Microwave:
Place the mug in the center of the microwave and heat on high for 1 minute and 15 seconds. Cooking time may vary depending on wattage (1100W baseline). The cake should rise and spring back when lightly pressed.
Cool Slightly:
Let the mug cake sit for 1 minute before serving. This allows the texture to set fully.
Glaze It (Optional but Exceptional):
Mix powdered sugar and lemon juice in a small bowl. Drizzle over the warm cake for a tangy-sweet finish.

- Avoid overcooking, which can lead to a rubbery texture. Start with 1 minute and add more time in 5-second increments if needed.
- Mug cakes cook best in a wide mug rather than a tall one to avoid overflow.

FAQs
Q1: Can I make this mug cake vegan?
Yes. Substitute dairy milk with almond or oat milk, and use coconut oil or vegan butter. It will still rise beautifully and taste delicious.
Q2: Why did my mug cake come out rubbery or dry?
Overcooking is usually the culprit. Start with 1 minute and increase in 5-second increments until done. Mug size and microwave wattage matter.
Q3: Can I double the recipe?
You can, but it’s better to make two separate mug cakes for even cooking. Doubling in one mug may lead to uneven texture or overflow.
