Chocolate Chip Low Carb Mug Cake Recipe

This Low Carb Mug Cake Recipe is a super easy dessert to make and can be whipped up in just minutes for when you have that “I need something really sinful” sweet craving!

Keto Chocolate Mug Cake

Being that I follow a very low-carb diet, I’m always looking for keto desserts I can make to satisfy my chocolate cravings and take care of my sweet tooth.

Believe me when I tell you, this can be very challenging!

Don’t get me wrong, I love me some fruit and luckily, on my plan, I can eat up to 3 fruits a day.

However, there are those times when I just want something involving chocolate!!

Sugar Free Chocolate

Thank goodness for the wonderful invention of sugar free chocolate.

And God bless Russell Stover who has been crafting small batch, delicious chocolate for close to 100 years now!

Being a fan of chocolate chips my entire life, I was a tiny bit apprehensive to use sugar free chocolate chips.

However, I was willing to try it if it meant I could continue with my low-carb lifestyle while splurging at the same time!

Russell Stovers Sugar Free Chocolate Chips

Not only does Russell Stover offer Dark Chocolate & Semi-Sweet Style Baking Chips, but also, they offer sugar free chocolate candies too.

And they’re really good!

Try them for yourself and tell me if you can tell that they’re sugar free!

Needless to say, I keep my pantry stocked with a nice variety of their chocolates!

How Do You Satisfy A Sweet Tooth On A Keto Diet?

To satisfy your sugar cravings on a keto diet, you find ingredients you can use that work as great substitutions for carbs and sugars.

In this case with my chocolate chip mug cake recipe, I used these keto substitutes:

  • Almond Flour 
  • Russell Stover Sugar-Free Chocolate Chips
  • A Natural, Non-Sugar Sweetener

Another thing that I love about this easy chocolate chip mug cake recipe is that I can eat the whole cake!

I mean, seriously, there’s just something so satisfying about being able to say that.

Of course mug cakes are single-serving desserts, so it’s easy to eat the entire thing AND you don’t have to share with anybody!

Whereas, if you were to make a whole batch of cookies, you’d be much more likely to overeat them.

Low Carb Mug Cake Recipe Ingredients

Here are the simple ingredients for this Chocolate Chip Mug Cake Recipe:

  • Small amount of Almond Flour (1/4 cup)
  • Peanut Butter
  • Whole Egg
  • Sugar Free Chocolate Chips
  • Artificial Sweetener (low-carb sweetener)
  • Vanilla Extract
  • Baking Powder
  • Melted Butter

Step-By-Step Directions For Low Carb Mug Cake Recipe

And here are the very simple steps for making this chocolate chip mug cake recipe.

Step 1: Beat Egg in Small Bowl

First, beat your egg.

Pretty self explanatory.

Step 2: Add Remaining Ingredients and Mix Well

Second, add all of the rest of the ingredients into the bowl and mix until well blended.

Again, very simple to understand.

Step 3: Pour Mug Cake Batter into Coffee Mug

Mix batter well

Lightly spray the inside of your mugs with cooking spray.

Initially, when I made this low carb keto mug cake recipe I poured all of the batter into one large, microwave-safe mug.

However, this recipe can be split into 2 portion sizes and made in two small coffee mugs.

Trust me when I say that it’s very filling!

Next time I’ll definitely make these into 2 chocolate chip, peanut butter mug cakes instead of one big one.

Portion control at it’s finest!

Step 4: Place Coffee Mug/Mugs in Microwave & Heat for 1 Minute

Cook in microwave for 1 minute

Finally, microwave chocolate chip mug cake for 1 to 2 minutes (keep an eye on it after 1 minute of microwave cook time) to watch the mug cake rise somewhat.

After that, use a toothpick inserted in the center of the mug cake to test that it is completely cooked through.

I sprinkled a few more sugar free chocolate chips on top of my chocolate chip mug cake when I took it out of the microwave.

Low Carb Mug Cake Recipe Substitutions

1-Minute Chocolate Chip Mug Cake Recipe: Sugar Free

Everybody has their own personal preferences as to what they consider to be the perfect low-carb mug cake.

Therefore, here are some substitutions you can use to make it taste just the way you want it.

  • Instead of peanut butter, use:
    • Almond Butter
    • Seed Butter
    • Nut Butter
    • Powdered Peanut Butter
  • Add in chopped nuts
  • Omit the chocolate chips altogether for a vanilla mug cake (unless you need a chocolate fix)
  • Substitute whole wheat flour for almond flour
  • Add in canned pumpkin for a pumpkin mug cake
  • Include ripe bananas as a topping or in the batter 
  • Swap coconut flour for almond flour
  • Add a dollop of whipped cream on top immediately before eating
  • Other popular mug cake flavors:
    • Peanut Butter Mug Cakes
    • Snickerdoodle Keto Mug Cake
    • Cinnamon Roll Mug Cake
    • Keto Brownie Mug Cake

How It Turned Out

Oh my gosh, this super easy recipe turned out heavenly!

Honestly, it’s the best mug cake I’ve ever had!

Needless to say, it was the perfect, moist cake consistency without feeling overly dense like some recipes are when using almond flour.

As a matter of fact, it was just like eating a hot, soft, gooey chocolate chip cookie with a spoon.


AND, with the fiber and sugar alcohols in this recipe, it comes out to only 6 grams of net carbs per serving and 11.5 grams of protein!

The sugar free chocolate chips melted just like normal chocolate chips and tasted amazing!

In addition, they had that rich chocolate flavor and there was no sugar free aftertaste which is huge for me.

Honestly, it ruins it for me if a sugar free dessert has a “sugar free” aftertaste.

So, the fact that this keto cake in a mug didn’t have that, gave this recipe that extra wow factor!

Because, when you’re on a low carb, no starch, no sugar diet, getting that wow factor is a big deal!

Next time I might try making it with coconut flour instead of almond flour just to see if it makes a big difference in the taste.

Although, if you’ve been on a keto diet for long, you know that coconut flour and coconut oil are used in a LOT of keto recipes.

So, I might just stick with the almond flour.
