What is a Keto Mug Cake?

A mug cake is literally what it sounds, an easy cake recipe made in a mug. A keto mug cake requires low carb ingredients, and it’s usually cooked in a microwave for 2-3 minutes.

It’s fantastic because you won’t have tons of dirty dishes. You might already have the ingredients in your pantry. This keto chocolate late mug cake IS FOR YOU!!

This is one of the recipes that I’m making almost every day. Sometimes I don’t even add sweetener because I like the bitter taste too. I love that the coconut flour absorbs the liquids well and it won’t be wet and eggy.

How to Make Keto Mug Cake?

The best thing of making a mug cake is you combine all the ingredients, cook the batter in the microwave, and enjoy it straight out your mug! Here are all the steps you’ll need to follow. For measurements, scroll down to the recipe card, where you can also find a printable form of the recipe.

  1. We’ll begin to combine the dry ingredients: the coconut flour, cocoa powder.
  2. Add the sweetener. You can add more or less, depending on your taste.
  3. Combine the wet ingredients: the melted butter, the beaten egg, the whipping cream, and the almond milk. Make sure you use unsweetened almond milk.
  4. Mix the dry and the wet ingredients together. If your mixture it’s too thick add more almond milk or water until it gets a nice brownie batter consistency.
  5. Butter your favorite mug and pour the mixture. Place it in your microwave for 2-4 minutes (depending on the power of your microwave) or until your skewer comes out pretty clean. Mine took 3 minutes to be perfectly cooked.

How to Serve Easy Low Carb Mug Cake?

You can serve it directly from your mug, but I prefer to put mine on a plate and serve it with some dark chocolate, cinnamon, and sometimes topped with coconut oil or peanut butter.

As you can see the consistency, it’s similar to the real chocolate brownie. Trust me, you’ll feel like eating the real thing.

Imagine eating this keto mug cake with fresh whipped cream on top or with vanilla keto ice cream. Sounds divine? Make it now and serve it with a delicious keto coffee.

    Omg Heaven! I’ve been looking for a good mug cake recipe and finally! This one is it I did add some natural peanut butter on top of it when it came out of the micro and added a little whipped cream. It was insanely Delish. Thanks for sharing, this is a keeper!!

  3. First attempt; recipe as listed. 2½ minutes in microwave. tasted ok, but really dry. Will try again tomorrow. a little more liquid at 2 minutes.

    1. Thank you for sharing your experience with making the Keto Chocolate Mug Cake! It’s not uncommon for microwave times to vary depending on the wattage of the microwave oven, so adjusting the cooking time and adding a little more liquid is a good approach. Experimenting with the recipe to achieve the desired moistness is a great idea, and I hope your second attempt turns out even better.
