But then you go back home and realize you have nothing in your cupboard to fix that chocolate craving.

So that’s when keto chocolate mug cake recipes come to the rescue.

What Is A Keto Chocolate Mug Cake?

A keto chocolate mug cake is a one-serve, 90-second microwave chocolate cake recipe made with low-carb flour and sugar-free sweeteners.

As a result, a keto mug cake recipe contains minimal carbs but brings out the same decadent chocolate, moist crumb you expect from a chocolate cake.

How To Make Keto Chocolate Mug Cake

This keto chocolate mug cake recipe is the easiest, quick keto chocolate cake you will make.

A keto chocolate mug cake is made with only 5 ingredients.

Ingredients

All you need to make this recipe are the nourishing low-carb ingredients below.

• Almond flour – mug cakes also work well with an almond meal. However, almond meal is coarse, and not everyone enjoys the grainy texture it adds to keto chocolate mug cakes. So if you are new to keto baking, always choose ultra-fine almond flour. It makes cakes and cookies with a similar texture to wheat-based baked goods. Learn more about keto flours.
• Coconut flour – this keto chocolate mug cake with coconut flour has the best texture! The combination of both flours creates the fluffiest cake crumb. Of course, if you don’t have coconut flour, you can replace it with 2 tablespoons of extra almond flour.
• Erythritol or any sugar-free crystal sweetener you like such as Lakanto or Swerve, or a few drops of liquid stevia.
• Egg – this easy mug cake keto recipe requires an egg. Try my egg-free keto chocolate mug cake for a vegan keto alternative.
• Unsweetened cocoa powder
• Baking powder 
• Vanilla extract
• Sugar-free chocolate chips  – I highly recommend adding a pinch of sugar-free chocolate chips to your mug cake for an extra chocolate flavor.

Combining Ingredients

In a small mixing bowl, beat eggs, melted coconut oil, vanilla extract, and almond milk.

Then stir in the flours, sweetener, baking powder, and unsweetened cocoa powder.

Finally, when the batter is thick and evenly combined, stir in the sugar-free chocolate chips.

Baking

The trickiest part of keto mug cakes is to bake them perfectly, to stay moist in the center but not liquid.

My tips to make the best single-serving mug cake recipe in the microwave are:

Use a microwave-safe tall coffee mug – from 8-15 oz. In fact, a tall coffee mug gives the keto mug cake room to rise high, adding fluffiness, and also it prevents the mug cake from overflowing from the mug.

Check microwave power and adjust baking time – like ovens, microwaves do have power settings.

Don’t assume that all microwaves are set at the same powder. It’s not true. However, the truth is some microwave settings can’t be changed.

It means that they are sold with a set up of 600W, 900W, or 1200W. So below, I listed the microwave baking time based on the power of each microwave:

600W – 130 seconds baking time

900W – 90 seconds baking time

1200 W- 60 seconds baking time

Serve immediately – a mug cake dries out quickly, don’t wait, and serve within 5 minutes to enjoy its full flavor.

Serving Ideas

This keto low-carb mug cake is even better served with toppings to enhance the rich chocolate taste!

Below I listed some options that are keto-friendly to make this chocolate mug cake even tastier:

• Whipped cream – can use dairy-free coconut whipped cream too for a paleo chocolate mug cake.
• Melted sugar-free chocolate.
• Natural peanut butter – as seen in my pictures, I added a drizzle of melted sugar-free chocolate and a drizzle of peanut butter on top of my low-carb mug cake. This is the most decadent addition to chocolate!
• Pecans – pecan nuts turn this mug cake into a delicious mug brownie.
• Keto Chocolate Frosting – to spread on top of the mug cake.

Storage Instructions

Unfortunately, baked keto mug cakes won’t store well. A keto mug cake recipe must be served immediately within 5 minutes after baking, or it dries out.

You can make the batter ahead 24 hours before serving. First, make the batter and fill a coffee mug with it.

Then, wrap the top of the mug with plastic wrap and store the uncooked mug cake in the fridge overnight. T

hen, bake the keto chocolate mug cake in the microwave when needed.
