- Small Mixing Bowl
- Fork or Whisk
Ingredients
- 2 tablespoons all-purpose flour
- 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
- 1 large egg
Instructions
- In a small mixing bowl, whisk together the flour, sugar, and baking powder until evenly combined.

- Microwave on high for about 1 minute and 30 seconds, or until the cake has risen and is set around the edges. You'll hear a gentle bubbling sound as it cooks.
- 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.
