Instructions:

1. Prepare the Mug: Make sure your microwave-safe mug is clean and dry. For ease of mixing, a larger mug with a wide opening is preferable.
2. Melt the Butter: Place the tablespoon of butter in the mug and microwave it for about 20-30 seconds until melted. Keep an eye on it to ensure it doesn't splatter or overheat.
3. Add the Sugar: To the melted butter, add 2 tablespoons of sugar. Use a fork or small whisk to mix until well combined.
4. Incorporate the Egg: Crack the egg into the mug. Beat the mixture with the fork or whisk until the egg is fully mixed with the butter and sugar.
5. Add Milk: Pour in the 2 tablespoons of milk. Mix well to incorporate all the ingredients.
6. Mix in Flour: Slowly add the 1/3 cup of self-raising flour to the wet ingredients. Stir until you have a smooth batter with no lumps.
7. Lemon Flavor: If you want a lemony touch, add the zest of one lemon and a few drops of lemon juice into the batter. Mix well to combine.
8. Microwave the Cake: Microwave the mug on high for 1 minute and 30 seconds to 2 minutes. The exact time will depend on your microwave's power. Start checking at 1 minute and 30 seconds. The cake is done when it has risen and is firm to the touch. Insert a toothpick in the center; if it comes out clean, the cake is ready.
9. Cool and Enjoy: Let the mug cake cool for a few minutes before eating, as it will be very hot. You can enjoy it straight from the mug or invert it onto a plate.

In just a matter of minutes, you can enjoy a warm, lemony cake that's perfect for satisfying your sweet tooth. Whether you're whipping it up for a quick dessert or a spontaneous treat, this Lemon Microwave Mug Cake is sure to impress with its simplicity and deliciousness. Happy baking and enjoy every tangy bite!

Lemon microwave mug cake FAQ:

How long should I microwave the cake?

Microwave the cake on high for 1 minute and 30 seconds to 2 minutes. Check the cake at 1 minute and 30 seconds, and it is done when it has risen and feels firm to the touch.

What type of mug is best for this recipe?

Use a microwave-safe mug that is clean and dry. A larger mug with a wide opening is preferable for easier mixing and to prevent overflow.

Can I substitute the self-raising flour?

Yes, you can substitute self-raising flour with all-purpose flour by adding a teaspoon of baking powder for every 1 cup of flour used. Adjust this accordingly for the 1/3 cup needed in the recipe.

How should I store leftovers?

If there are any leftovers, store the mug cake in the refrigerator in an airtight container for up to 1 day. Reheat in the microwave for a few seconds before enjoying.

What if my mug cake doesn't rise?

If your mug cake doesn't rise, it may be due to old or expired self-raising flour, or the microwave time was too short. Ensure all ingredients are fresh and try microwaving a little longer.

Cooking Tips:

- Make sure to thoroughly mix all the ingredients to avoid any lumps for an even bake.

- Use a microwave-safe mug that is at least 12 ounces in size to allow space for the cake to rise.

- Keep an eye on your mug cake while it's cooking, as microwave wattages vary and can affect the cooking time.

- Add a teaspoon of lemon zest or a few drops of lemon extract for an extra burst of lemon flavor.

- Allow the mug cake to cool for a minute or two after microwaving to let the flavors meld.

- Top with powdered sugar, fresh berries, or a dollop of whipped cream for added indulgence.
