Ingredients
  

  • 4 tbsp all-purpose flour
  • 2 tbsp granulated sugar
  • 1 tsp baking powder
  • 1 pinch salt
  • 1 tsp lemon zest freshly grated
  • 3 tbsp milk
  • 1 tbsp vegetable oil
  • 1/2 tsp vanilla extract
  • 1 tbsp fresh lemon juice

Equipment

  • Microwave-safe mug
  • Mixing spoon or fork
  • Measuring spoons
  • Kitchen scale (optional)

Method
 

  1. Combine the dry ingredients—flour, sugar, baking powder, salt, and lemon zest—in a microwave-safe mug. Stir until evenly mixed using a spoon or fork.
    4 tbsp all-purpose flour, 2 tbsp granulated sugar, 1 tsp baking powder, 1 pinch salt, 1 tsp lemon zest
  2. Add the milk, vegetable oil, vanilla extract, and lemon juice to the mug. Mix thoroughly until a smooth batter forms, with no lumps remaining. The mixture should be slightly thick but pourable.
    3 tbsp milk, 1 tbsp vegetable oil, 1/2 tsp vanilla extract, 1 tbsp fresh lemon juice
  3. Place the mug in the microwave and cook on high for about 2.5 to 3 minutes. Stop when the cake has risen and is just set in the center, with a lightly springy top. You should hear a slight ping or bubbling sound, and the batter should no longer be liquid.
  4. Remove the mug carefully from the microwave and allow the cake to rest for 1 minute. It will slightly deflate and firm up as it cools.
  5. Optionally, garnish the mug cake with a sprinkle of lemon zest or a dusting of powdered sugar for presentation. Serve directly in the mug for a warm, bright lemon treat.
