The Ketogenic Diet is an amazing way to eliminate nasty sugar cravings.
But even if you’re completely fat adapted and carbs don’t bother you anymore, you’ll probably still face some sweet cravings once in a while.

If you don’t – congratulations!
But if you stumbled onto this post while searching for something sweet you can have while doing the keto diet – I’ve got you covered!

This moist chocolate keto mug cake with a peanut butter core is just… amazing.
I’ve tried so many ketogenic mug cake recipes before and to be honest – most of the time I was quite disappointed.
Yeah it tasted sweet and my cravings disappeared, but they more often than not tasted dry and stale.

Well, this one is different!
It’s a keto mug cake that actually tastes great!
And it’s so quick and easy to make that you have no excuse to fall off the wagon with “real” chocolate cake!

 

 
 

Keto Chocolate Mug Cake with Peanut Butter Core: Ingredients

 
This ketogenic chocolate and peanut butter mug cake is easily made with ingredients anyone who’s on a low carb diet probably already has at home.

All you need is:
☞ finely ground coconut flour,
☞ finely ground almond flour,
☞ erythritol (or another keto-friendly granulated sweetener of your choice,
☞ baking powder (choose a gluten-free one without corn starch or make your own for paleo option),
☞ a pinch of salt,
☞ coconut oil (you can use butter or ghee to replace the coconut oil),
☞ unsweetened almond milk (or coconut milk),
☞ an egg,
☞ unsweetened baking cocoa powder (also known as dutch cocoa powder) &
☞ unsweetened peanut butter.
 


 
The moist peanut butter core and the sweet, chocolaty cake base complement each other in the perfect way.
But of course, you can use any other unsweetened nut butter of your choice as an alternative.
 

 
 

Tips & Instructions for Baking Your Keto Mug Cake

 
Start by adding all of your ingredients except the peanut butter into a bowl.
I recommend using a separate bowl or mug, not the one that you will use for baking because you need to add the peanut butter core as well.

Mix all of the ingredients until you get a smooth and chunk-free cake batter.

To help your mug cake rise and make it fluffy, grease your oven- and microwave-safe mug or bowl with a tasteless plant oil or oil spray (I recommend using avocado oil or sunflower oil).
This will also help you to get your cake out of the mug without having to scrape it off.

Continue by adding half of your chocolate cake batter to the mug.
Make sure to choose a mug or bowl that’s at least double the size of the volume of your ingredients.
Your mug cake will rise quite a bit and this way you’ll avoid having to clean your microwave afterward.

Add the tablespoon of unsweetened peanut butter to the center and finish by adding the rest of your cake batter to your mug.
 

If you choose to bake your keto mug cake in the microwave:

 
Pop your mug with the cake batter inside your microwave and microwave for about 60 seconds.
The time may vary depending on what microwave and what settings you’re using.
To be on the safe side and to avoid a dry chocolate mug cake, microwave it for a shorter time (50 seconds) at first and test your cake before overcooking it.

A great way to do this is with the “prick test”: take a toothpick and prick the center of your cake with it. If the toothpick comes out “clean” you’re good to go!

If the toothpick has bits of cake batter on it, pop it back inside of your microwave for a few more seconds.
 

If you choose to bake your keto mug cake in the oven:

 
It’s just as easy as the microwave option, it just takes a few minutes longer!

Preheat your oven to 350 degrees Fahrenheit or 180°C before mixing the ingredients for your cake batter.
Put your oven-safe mug inside of your oven and bake it for about 10-15 minutes.

Like with the microwave option, just test if your mug cake is finished by pricking it with a toothpick!
If you would like to add a bit of decoration to your mug cake, add a bit of shredded sugar-free chocolate or chocolate sprinkles once it has cooled off!

Once your keto mug cake is done, grab yourself a spoon and enjoy your well-deserved treat!
