Description
A bright and sweet lemon mug cake made with fresh lemon zest, lemon juice, and vanilla — soft, fluffy, and ready in under two minutes for the perfect quick dessert.
Ingredients
2 tablespoons granulated sugar
1 tablespoon oil or melted butter (any neutral oil works)
1/2 teaspoon pure vanilla extract
3/4 teaspoon lemon zest
2 tablespoons milk (room temperature)
1 tablespoon fresh lemon juice
4 tablespoons all-purpose flour
1/2 teaspoon baking powder
A pinch of salt
2 tablespoons whipped cream (for topping)
A sprinkle of lemon zest (optional for garnish)
Instructions
In a microwave-safe mug, add oil, lemon zest, lemon juice, sugar, and vanilla extract. Mix well.
Add milk and stir until smooth.
Add flour, baking powder, and salt, then fold gently until the batter is creamy and lump-free.
Microwave on full power for 60 seconds, or until the center is fully cooked. If needed, add 15-second bursts.
Carefully remove the mug (it will be hot). Let the cake cool for 2–3 minutes.

Making the Perfect Lemon Mug Cake at Home
Lemon mug cake is one of those desserts that feels like a burst of sunshine, even on the cloudiest day. It’s quick, cozy, and full of bright flavor, made right in the same mug you’ll eat it from. I love how this recipe turns simple pantry staples into something special in just minutes. The sweet tang of lemon, a touch of vanilla, and that soft, fluffy texture it’s comfort in the purest form.
To make your own lemon mug cake, you’ll need:
- 2 tablespoons granulated sugar
- 1 tablespoon oil or melted butter (any mild, flavorless type works)
- ½ teaspoon pure vanilla extract
- ¾ teaspoon fresh lemon zest
- 2 tablespoons milk at room temperature
- 1 tablespoon freshly squeezed lemon juice
- 4 tablespoons all-purpose flour
- ½ teaspoon baking powder
- A pinch of salt
Start by adding the oil, lemon zest, lemon juice, sugar, and vanilla directly into a microwave-safe mug. Stir until the sugar starts to dissolve and the mixture smells fragrant. Add the milk, then mix in the flour, baking powder, and salt until smooth and lump-free. The batter should look creamy, not runny.
Place the mug in the microwave and cook for about 60 seconds on full power. If the center still looks slightly wet, cook for another 10–15 seconds. The top should look set and spring back gently when touched. Let it cool for a minute or two before digging in this helps the flavors settle beautifully.
You can top your lemon mug cake with a spoonful of whipped cream, a drizzle of lemon glaze, or even a scoop of vanilla ice cream if you’re feeling indulgent. And if you love this zesty sweetness but want a bit of crunch, try my Lemon Poppy Seed Mug Cake it’s a deliciously textured variation on the same bright flavor.
Serving and Topping Ideas for Lemon Mug Cake
When your lemon mug cake comes out of the microwave, the aroma alone is enough to make you smile. It’s soft, golden, and steaming with that sweet lemon fragrance that instantly brightens your mood. I usually let mine cool just enough to touch because that first warm spoonful is pure bliss.
This cake doesn’t need much to shine, but the right topping can make it even more special. A swirl of whipped cream gives it that light, cloud-like finish. If you want a touch of extra tang, drizzle it with a simple glaze made from powdered sugar and lemon juice. The glaze melts over the warm cake and sets with a soft sheen that looks almost too pretty to eat.
Some days, I add a scoop of vanilla ice cream right on top and watch it slowly melt down the sides. Other times, I sprinkle crushed graham crackers for a playful twist, or a few berries for a pop of color. This lemon mug cake is versatile perfect for a solo treat or an after-dinner dessert that looks like it took hours to make.
If you’re feeling festive or want to pair it with something indulgent, try serving it alongside my Black Friday Fruit Dessert Mug. The rich, fruity sweetness complements the brightness of the lemon perfectly, making the two an unforgettable combination for any celebration or cozy night in.
And just like that, with a mug, a spoon, and a bit of zest, you’ve created a dessert that’s soft, bright, and soul-warming. It’s proof that happiness doesn’t always need a baking pan it sometimes fits right in your hands.
