Five Minute Lemon-Poppy Seed Cake

¼ cup all-purpose flour

¼ cup white sugar

3 tablespoons buttermilk

3 tablespoons vegetable oil

½ teaspoon baking soda

1 tablespoon poppy seeds

1 teaspoon lemon extract

1 egg

Whisk flour, sugar, buttermilk, vegetable oil, baking soda, poppy seeds, and lemon extract together in a bowl until smooth. Beat in the egg. Pour batter into a large microwave-safe glass or ceramic mug or cereal bowl.

Heat in the microwave on high until a toothpick inserted into the center comes out clean, about 3 minutes.
