- 1 tablespoon granulated sugar
- 1/4 teaspoon baking powder
- 1 tablespoon fresh lemon zest about half a lemon
- 1 tablespoon fresh lemon juice about half a lemon
- 1 tablespoon vegetable oil

- Carefully remove the mug from the microwave, and check the cake’s firmness with a toothpick or fork. If it comes out clean, it’s ready; if not, microwave for an additional 10-15 seconds.
