(3 Min!) Chocolate Mug Cake

Ultra Speedy (‘N Easy!)

This keto chocolate mug cake is dedicated to the lazy baker in all of us! But keep in mind that lazy in no way means ‘less discerning’, as this little guy right here might even rival our famous chocolate cake.

That’s right! It seems that microwaving keto batters makes them extra (extra!) fluffy. So your mug cake should nearly double in size (albeit collapse somewhat… per keto standards).

Still, it’s nothing less than a beautiful chocolate cake through and through. Add in some chocolate chunks, serve up with vanilla ice cream (or whipped cream!), or how about some salted caramel (!!). Or simply delicious as is.

The Method

Mix, microwave… that’s it! Just be sure to leave ample space for rising (3-4 fingers).

The Sweetener

You’ve got plenty of options for this keto mug cake. Think xylitol and allulose (no aftertaste), Lakanto (barely any aftertaste… if at all?), and Swerve (some slight cooling sensation).

Fun fact: it might also be my taste buds here, but I’ve noticed that stevia-based sweeteners (such as Pyure) don’t work so great when chocolate is involved as the aftertaste is accentuated. So I cannot recommend enough that you don’t use stevia-based sweeteners here.

Oh, and if just paleo or gluten free (or not restricted by sugars), simply sub 1-to-1 with coconut or regular sugar.

The Flours

You’ll need some super fine almond flourgolden flaxseed meal (or psyllium husk powder), coconut flour and a touch of xanthan gum.

Just keep in mind that for best texture and rise, you’ll always want to regrind your flaxseed meal in a dry blender or bullet.

In terms of brands, for the almond either Anthony’s or WellBees work great. Both are super fine grinds. And for coconut I always favor Anthony’s here (honestly best taste by a mile!).

The Chocolate

You’ll want to use a Dutch-processed alkaline cocoa here. As there’s baking powder involved, using cacao won’t give the same results (at all!).

In terms of brands, my favorite will forever be Valrhona, known to be one of (if not the) best cocoas in the world. But as long as it reads ‘cocoa’ you’ll be fine!

Ingredients

For the keto mug cake

Instructions

  1. Melt butter in a medium (microwave safe!) bowl. Whisk in cocoa and sweetener to taste (see notes), and mix until well combined. If using erythritol, your batter will likely be very thick. 

  2. Whisk in the egg and mix until smooth (if using xylitol and allulose) or until thoroughly combined (with granular erythritol, which doesn't dissolve as readily). Mix in the rest of the ingredients and spoon the (very thick!) batter into a mug. 

  3. Place a paper towel into the microwave and set the mug on top (to catch any overflowing batter). Cook on high for 70-80 seconds. Time can vary a lot in microwaves, but to give you an idea I do 75 on 1000 watts. 

Recipe Notes

*Please see section on sweeteners for deets and possible substitutions. If using allulose (which is 70% less sweet) stick to the upper suggested range. And keep in mind that keto sweet buds vary drastically, so feel free to play around with the sweetness that suits you! 

**Same thing with the cocoa, 2 TBSP will give you a darker chocolate version while 1 1/2 TBSP (or even one?!) will give you a lighter one!

Please note that a batch yields a (very large!) mug cake (think the equivalent of two muffins!). So feel free to portion out (think half post dinner and the rest for lunch!).

    Just made two of these for my boyfriend and I. We omitted the sweetener and just shoved a square of 85% dark chocolate into the middle for sweetness. It’s delicious! It has a nice buttery flavor and moist, bready texture (chose the psyllium husk because I like the taste 🙂 Thanks for sharing! Your recipes are great!
