Equipment

Microwave-safe mug
Measuring spoons

Ingredients

2 tablespoons all-purpose flour sifted
2 tablespoons granulated sugar
1/4 teaspoon baking powder
1 tablespoon fresh lemon juice about half a lemon
1 tablespoon vegetable oil or melted butter
1 teaspoon lemon zest optional, for extra brightness

Instructions

Add the sifted flour, sugar, and baking powder directly into a microwave-safe mug. Stir well to combine, creating a dry mixture with a slightly grainy texture.
Pour in the fresh lemon juice and vegetable oil, then use a fork or small whisk to stir everything together until a smooth, slightly thick batter forms. You should see a bright yellow hue and a fragrant citrus aroma emerging.
If using lemon zest, sprinkle it over the top of the batter now for an extra burst of flavor. Gently fold it in with a toothpick or skewer if you'd like.
Place the mug in the microwave and cook on high for about 60 seconds. Keep an ear out for bubbling or sizzling sounds as the cake rises;
it should look puffed up and feel springy to the touch once done. The surface may crack slightly, indicating it's perfectly cooked.
Carefully remove the mug from the microwave using a pot holder or cloth. Let it sit for a minute; the residual heat will finish setting the cake.
Garnish with a sprinkle of powdered sugar, lemon zest, or a small wedge of lemon if desired. The cake should look moist and fluffy with a bright yellow color.

Notes

Serve immediately for the best texture. You can add a dollop of whipped cream or a few berries for extra indulgence.

So next time your day needs a little extra sparkle, reach for this Lemon Mug Cake. Its quick prep and vibrant flavor make it a standby for busy mornings or late-night cravings.

Enjoy the zing of lemon and the cozy warmth of this humble treat. It’s a small reminder that sometimes, the simplest recipes can deliver the biggest smiles.
