When you want to curl up in a light spring blanket with a warm lemon cake and dream of cherry blossoms and Easter and all things bright and beautiful, treat yourself to a lemon mug cake.

You’ll be glad you did!

Lemon Mug Cake Inspiration

When cherry trees begin to hint at the beautiful pink blossoms to come, lemon flavors capture my imagination.

It might be that Easter is just around the corner, along with warmer days and hopefully clear blue skies in Seattle. It’s on these days when light, brightly flavored treats come to mind.

This year, when beginning to think about spring desserts, lemon cake was at the top of my list. I then began to wonder… why couldn’t you also make a lemon cake for one?

In two minutes. In the microwave?

Many tries and testing answered that question. You absolutely can make a lemon cake in two minutes in the microwave… and it’s delicious!

And it satisfies those lemon cravings… for the moment 🍋!

If the spring season has you thinking about carrot cake, we have solutions for that craving as well. Be sure to look at my Carrot Cake in a Mug recipe or the simple Easy Carrot Cake Loaf recipe. Both are delicious!

So here’s to a quick and easy spring treat with the delicate flavors of the season.

Enjoy!

Ingredients for Lemon Mug Cake

You can find the ingredient measurements in the recipe card at the bottom of this post, but here is the list of what you’ll need to make lemon cake… in a mug!

  • Melted butter for flavor and moisture
  • Milk: Dairy or nondairy, both work well
  • All-purpose flour: If using self-rising flour, eliminate the baking powder
  • Baking powder for rise
  • Lemon: Fresh lemon juice makes this mug cake even more delicious. And if you want to elevate the lemon flavor even more, add a bit of the zest as well.
  • Powdered sugar: While you can use granulated sugar, I love the delicate texture of powdered sugar in this cake. Add a splash of vanilla, too.
  • Toppings: A dollop of whipped cream is delicious on top, as it is vanilla ice cream or simply a dusting of powdered sugar.
  • Optional: Adding 1 drop of yellow food coloring enhances the color.

How to Make Lemon Mug Cake

Full step-by-step instructions are in the recipe card at the bottom of this post, but this is a quick overview of how to make this oh-so-delicious lemon mug cake.

1

Melt butter

In a bowl or a mug, melt butter in the microwave.

2

Make the lemon cake batter

Whisk milk, lemon juice, and vanilla in a small bowl with the melted butter. Then, whisk in flour and baking powder until well mixed.

Microwave mug cake

Microwave on high for 1 to 1 and 1/2 minutes (90 seconds). The timing of the mug cake will depend on the size of your mug and your microwave. Be careful not to over-microwave. The top will be just set. In my microwave, it is perfect at 1 minute 10 seconds.

Let the mug cake cool slightly before eating. Top with whipped cream, vanilla ice cream, or simply a dusting of powdered sugar (or make a quick glaze with powdered sugar and water). Top with a sliced lemon for a fancy touch.

Mug Cake Pro Tips

  • While you can mix the ingredients in the mug, I find blending the ingredients in a separate bowl results in the best mug cake.
  • Be sure to mix the ingredients well. Much like a traditional cake, begin with the wet ingredients, whisk well, and then fold in the dry ingredients until incorporated.
  • Don’t over-microwave the mug cake; it can become overdone quickly.
  • Let the mug cake cool before enjoying it; it’s super hot when it comes out of the microwave. Topping like ice cream helps cool it down quickly.

Lemon Mug Cake FAQ and Tips

What size mug are you using in this recipe?

I’m using a 12-ounce mug. You can measure the size of your mug by filling it with water, pouring it into a glass measure, and converting it to ounces. Be sure the mug you’re using is microwave-safe.

Can I make more than one mug cake at a time?

Yes, you can easily double or triple this recipe to make multiple servings. Adjust the quantities of each ingredient accordingly and divide the batter evenly among individual mugs before cooking. Remember that you may need to increase the cooking time slightly for larger batches.

Can I make this mug cake ahead of time?

Mug cakes are best enjoyed fresh, straight out of the microwave. You can prepare the dry ingredients in advance and store them in airtight containers, then mix the wet ingredients, and cook the mug cake just before serving for the best taste and texture.

How do I know when the mug cake is done cooking?

Cooking times may vary depending on your microwave’s wattage, but a good rule of thumb is to cook the mug cake in 30-second intervals and check for doneness after each interval. The cake is done when it has risen and appears set on top.
