Lemon Mug cake

This Lemon Cake in a mug is incredibly soft, light, fluffy and made from scratch. My family loves this for a quick weeknight dessert when I’m not in the mood to bake an entire cake. It is quick, easy, single serving and is made without eggs. It uses no extract and no fancy ingredients–just fresh-squeezed, real lemon flavor.

Mug cakes are handy when you’re not in the mood to bake an entire cake like this Red velvet cake in a cup , Microwave Breakfast Muffin, or banana muffin in a mug

A delicious no butter single serve dessert that can be enjoyed without a glaze. But, if you wish then simply stir together some confectioners sugar with a dash of fresh juice until smooth and reached the consistency of glaze.

Why you’ll love this recipe?

  1. Cooks in Microwave – No turning on the oven or stove top.
  2. Quick and Easy – Ready in about 2 minutes and all ingredients are mixed in the mug, making clean up a breeze.
  3. Perfect summer dessert – Made with fresh citrus and topped with sweet ripe blueberries, this is perfect for the season.
  4. Single serve – My favorite part of all mug cakes.

Can I use water instead of milk?

You could, but we highly recommend NOR DOING SO! Milk adds richness (this is a dessert after all) and more flavor when compared to just water.

Use only fresh juice

The only flavoring in the dessert is from fresh lemon juice. So, please do not use the bottled kind.

I don’t see zest in the ingredients?

Yes! We tried various proportions of zest, but it tends to add bitterness due the small portion size of the cake. Hence this recipe does not call for zest! If you wish to pack a more lemony flavor, then we recommend topping the finished gateau with a lemon glaze.

Can I use lemon extract?

This is a single serve dessert recipe that might become way too lemony when using extract. The juice used adds enough tanginess and flavor. So, there is no need for extract.

What does lemon do to a cake?

The juice not only adds a bright citrusy flavor, but also works to activate the baking powder and creates a little extra softness to the cake.

How long to cook?

Cooking time depends on the size of mug used. It takes 1 minute + 40 seconds if using a wider mug and 1 minute + 45 seconds if using a narrow mug.

Enjoy HOT

Some MICROWAVE baked cake recipes might get a little dry if left at room temperature for a long period of time. So, we highly recommend enjoying it hot.


Basic baking ingredients like all purpose flour, baking powder, sugar, milk, vegetable oil along with freshly squeezed juice.

Pro Tips for Success

  • Make it vegan – Use with plant based milk like almond milk.
  • Stir batter until lump free – Using a spoon, stir the batter until smooth and no lumps remain.
  • Measure the flour correctly – Adding too much or too less is the most common mistake in a baking recipe. The best and easiest way to measure flour is to fluff the flour with a spoon, sprinkle it into your measuring cup, and use a knife to level it off. If you scoop the flour straight from the bag, you overpack the measuring cup.
  • Microwaves differ – This recipe was tested in two different microwaves and it took 105 seconds in one and 125 seconds in the other.
  • Best eaten hot – Enjoy this HOT! As with microwave desserts, some might dry out a little when left at room temperature.


  1. Poppy seed – Stir in 1 to 2 teaspoons poppy seeds into the batter.
  2. Use lime juice instead.
ingredients needed to make cake in microwave.

How to make?

  2. Stir wet – Mix milk, oil and freshly squeezed juice, mix until smooth and lump free.
  3. Cook – Microwave for one minute and 45 seconds.

How to serve?

Enjoy this made from scratch recipe, HOT as soon as you remove from the microwave with big scoop of sweetened whipped cream or vanilla ice cream.

Topping ideas

  1. Vanilla ice cream
  2. Sweetened whipped cream
  3. Fresh blueberries, raspberries or strawberries
  4. Banana slices
  5. Sweetened greek yogurt
  6. Fresh zest
  7. Lemon Glaze – Stir together 2 tablespoons confectioners sugar and about 1/2 teaspoon lemon juice until smooth and drizzle over hot cake.

Frequently asked questions

How many calories in this recipe for one?

The recipe makes one serving and it contains 661 calories.

Can I make this ahead of time?

As with all microwave cakes, it is best eaten hot. They tend to get dry if left at room temperature for some time. The best part of this recipe, it serves one person, so there is no need to worry about leftovers.

Can I add blueberries into the batter?

Yes, however we found that most of it sank to the bottom upon cooking. So, we opted for topping the finished dessert with fresh blueberries instead.
