Ingredients
- 2 tablespoons unsalted butter, melted
- 2 tablespoons granulated sugar
- 1 large egg yolk
- 1 tablespoon freshly squeezed lemon juice
- ½ teaspoon lemon zest, optional, but recommended
- 2 tablespoons whole milk
- ½ teaspoon pure vanilla extract
- ¼ cup all-purpose flour
- ¼ teaspoon baking powder
- 1 pinch kosher salt
Lemon Glaze
- 2 tablespoons confectioners' sugar
- ½ to 1 teaspoon freshly squeezed lemon juice
Instructions
- Lightly spray an 8-ounce microwave-safe mug with nonstick cooking spray and set aside.
- In a small mixing bowl, whisk together the melted butter and sugar until smooth.
- Add the egg yolk, lemon juice, lemon zest (if using), milk, and vanilla. Whisk until fully combined and smooth.
- Stir in the flour, baking powder, and salt just until no dry streaks remain. Do not overmix.
- Pour the batter into the prepared mug.
- Microwave on high for 60 to 90 seconds, or until the top is just set and springs back lightly when touched. Avoid overcooking; the cake will continue to firm up as it cools.
- While the cake cools slightly, make the glaze. In a small bowl, stir together the confectioners’ sugar and lemon juice until smooth and pourable.
- Drizzle the glaze over the warm mug cake. Serve immediately.
