How do you make low carb mug cakes?
Often, 5 minutes is all you have for a quick snack to refill and energize your body on a Ketogenic diet. Life is so busy these days that you just can’t afford to spend an hour just to make a cake.
Since I’m suggesting you make a Keto cake in a mug, you’ll need to use a microwave and you might need a few experiments before you get the perfect cake, but it’s totally worth it!
You see, a lot will depend on the settings and power of your microwave – this is all so individual that you’ll definitely will need to adjust the recommended timing. It’s always better to start with lower time and if the cake is undercooked, you can always give it a few more seconds.
Another factor that will affect the cooking time is the size of your mug. Often, the same volume of cake can be better cooked when divided between 2 smaller cups instead of being in one big mug.
Are mug cakes healthy?
Another consideration before we move on to the collection of delicious, quick and low-carb Keto mug cake recipes, is whether mug cakes are healthy.
Lots of discussion around the health concerns of microwaved food, and I’m no authority in the scientific world to tell you whether to believe these speculations or not.
I can only give you a link to FDA’s official information on Microwave Oven Radiation. Here are the lines I found particularly interesting for our question about mug cakes here:
Microwave cooking does not reduce the nutritional value of foods any more than conventional cooking. In fact, foods cooked in a microwave oven may keep more of their vitamins and minerals, because microwave ovens can cook more quickly and without adding water.
And in reality, when you have only 5-10 minutes to have a quick snack in the middle of a super-busy day, cooking a cake in the oven is not an option.
Is Chocolate allowed in Keto diet?
Yes, it is! But you have to use dark chocolate as it contains less sugar (choose chocolate that contains 70-100% of cacao).
Do you know that cacao is one of the most powerful antioxidants on this planet? And your Keto desserts will taste amazing while being super healthy!
My favorite dark chocolate has 85% of cacao, it’s organic and the taste is so balanced, just perfect!

What desserts can you have on a Keto diet?
Keto mug cakes are just one of the many desserts you can have on a Keto diet. People seem to have difficulties believing that low carb desserts even exist.
A dessert equals sugar, right? Not really, if you use different sweeteners and keep carbs really low using non-traditional flour. In some recipes, you can get as low as zero-carb desserts.
