Low Carb Keto Chocolate Mug Cake

Last updated on May 15th, 2019 at 10:02 pm

This gooey chocolate brownie is the best keto chocolate mug cake you’ll ever make and it’s ready in less than 2 minutes! Plus, it’s entirely gluten free, sugar free and dairy free. A nut free option is also available for those who are nut free.

The Best Chocolate Mug Cake Recipe

We all have chocolate cravings, I know I do.  That’s why I make sure to have a list of treats that I can make in no time when I have such cravings.

This low carb mug cake is definitely one of my favorite treats to make when in a hurry or when I need a chocolate treat ASAP. But it’s also one of the gooiest, moistest and chocolatey cake that I’ve ever made, which is why this is on the menu at least twice a week!

I think I’ve been going through chocolate withdrawal since I finished eating all of my avocado brownies and that’s why I needed a quick 2 minute mug cake to satisfy all of my cravings!

But the greatest thing about this low carb mug cake is that it’s completely sugar free, gluten free and dairy free. Plus it can easily be made nut free! I also provided instructions to make it with different sweeteners.

What Sort of Mug or Cup Should I Use?

Make sure you use a large cup or mug that can hold at least 1.5 cups of liquid.  That’s the most important part.  If your mug or cup is too small, the cake will overflow out of the cup and create a huge mess in your microwave (personal experience).

If you don’t want to use a cup, you can also use a large ramekin dish.  Ramekins are both microwave-safe and oven-proof so they are quite handy to have on hand.

Use a Microwave Safe Mug

Also, make sure you use a microwave-safe mug or cup.  Do not use glass as glass will shatter in the microwave from the heat of the cake.

How Many Carbs in this Low Carb Mug Brownie?

This low carb mug brownie has about 7.86g total carbs, with 4.3g fiber including sugar alcohols.  This single serving brownie has 3.56g net carbs.  This is the nutritional information for the almond flour and Lakanto version of this chocolate mug cake. If you switch the ingredients, just know you’ll have to recalculate the macros.

Possible Toppings

If you’re like me then you’ll need to top your low carb chocolate mug cake with some sort of topping! Here are some of my favourite low carb options:

• Sugar Free Whipped Cream
• Coconut Whipped Cream
• Keto Cream Cheese Frosting
• Sugar Free Chocolate Chips
• Keto Peanut Butter Chocolate Ice Cream
• Chopped Hazelnuts, Almond Slices or Macadamia Nuts
• Sugar Free Ice Cream
• Fresh Blackberries, Raspberries or Strawberries.

What Sweeteners Should I Use?

You have a couple of options to make this low carb mug cake, including erythritol, Lakanto, Sukrin, xylitol, stevia and monk fruit.  My favourites include Lakanto, Sukrin and xylitol.  My least favourite was definitely stevia (a very rare occasion) as it left quite a big of a bitter taste and didn’t go very well with the chocolate flavour.

If you decide to use erythritol, Lakanto or Sukrin, know that you’ll have to eat the keto mug cake as soon as it’s cooked.  Try not to chill it in the fridge afterwards as the erythritol will crystalize and you’ll have a huge grainy texture in your keto mug cake.  Since I made so many versions using different flours and sweeteners, I couldn’t possibly eat all of the keto chocolate mug cakes so I left many in the fridge overnight and all of the ones made with some kind of erythritol turned grainy.

If you use xylitol, it’ll stay perfect even if chilled in the fridge as xylitol does not crystalize in cooler temperatures.  Just be careful you don’t have a dog around as it can be toxic to the little pups!

• 2.5 tbsp erythritol (leaves a little bit of a cooling sensation)
• 2 tbsp Lakanto
• 2 tbsp Sukrin
• 2 tbsp xylitol
• 1/4 tsp stevia extract powder
• 1/4 tsp monk fruit extract powder

How to Make this Keto Mug Cake?

Lucky for you, it’s ridiculously easy to make this chocolate keto mug cake.  7 ingredients and 3 steps later you’ll have yourself a delicious homemade low carb mug cake.

First, you’ll want to mix the dry ingredients together in a large mug or cup that’s microwave-safe.  Then you’ll add in the wet ingredients and mix again until there are no more flour bumps.

Lastly, you’ll pop your mug into the microwave and microwave for 1 minute 30 seconds to 1 minute 40 seconds at 600W.

Once that’s done, your keto chocolate mug cake is ready to eat. Serve with your favourite toppings or as is, and your sweet tooth will be satisfied for the day.

How Long Should I Microwave my Mug Cake?

You should microwave your healthy chocolate mug cake for 1 minute and 30 seconds or 40 seconds.  Since my microwave is a 600W one, I needed to microwave my keto chocolate mug cake for 1 minute and 40 seconds and the sides and top were still a little wet, just how I like it.

I don’t recommend microwaving your keto mug cake more than 1 minute and 40 seconds as the chocolate might start to burn.

Can I Bake the Mug Cake Instead?

Yes! Simply bake it for 22 minutes at 180C/350F and you’ll have a super gooey chocolate mug cake ready to be eaten!  Just make sure to use an oven-safe bowl or ramekin as you don’t want your cup to shatter in the high heat.

Cacao or Cocoa?

Both work and both are equally delicious! Just use whichever one you have on hand and you’ll have a 2 minute mug cake ready to eat in no time!

Allergic to Nuts?

If you’re allergic to nuts, then you can make my nut free mug cake instead! I give three options that you can choose from depending on what type of flour you have on hand.  Simply replace the 2 tbsp of almond flour for 2 tsp coconut flour, 1.5 tbsp sesame flour or 2 tbsp powdered peanut butter flour.   The peanut flour kind of tastes like a peanut butter cup so it’s one of my favourite nut free flour for this keto mug cake recipe.

Since there isn’t a lot of coconut flour, the coconut flour mug cake does not taste like coconut, which is a relief because I absolutely hate the taste of coconut.  The sesame flour works, but makes the cake a little dry and crunchy from the seeds.

Final Tips Recap & Notes

Here is a recap of all the tips and substitutions you can make for this low carb mug cake recipe!

1. Note that this low carb chocolate mug cake can be made with only 1 tbsp of refined coconut oil instead of 2, but it comes out way less moist.
2. Make sure to use refined coconut oil and not extra virgin so that you don’t get a coconut taste in your brownie batter!
3. Instead of coconut oil, you can use butter, ghee, shortening, or cocoa butter.
4. The espresso powder is completely optional, but it does give it a nice kick.
5. Instead of 2 tbsp of almond flour, you can switch it for 2 tsp coconut flour, 2 tbsp sesame flour or 2 tbsp peanut flour.
6. Instead of 2 tbsp of Lakanto Golden, you can use 1/4 tsp stevia powder or monk fruit powder, 2.5 tbsp of erythritol, 2 tbsp of Sukrin Gold, or 2 tbsp of xylitol.
7. Instead of microwaving this microwave chocolate mug cake, you can bake it in the oven for 22 minutes at 180C/350F.
8. Instead of almond milk, you can use any other type of milk you want.  This could be any other nut milk, dairy milk, or heavy cream.
9. You can use from 1 tbsp to 1.5 tbsp of cacao powder.  I much prefer the 1.5 tbsp version as its way more chocolatey.
