Life is all about making your choices. Your choices determine the rest of your path. Keto, for me, is not just a diet. I am not doing this just to shed the extra kilos. For me, this is a lifestyle choice. Keto makes my body and mind feel good. The only obstacle for me is the occasional cravings. ‘Cravings’ is not even the correct term. It is more like – I am missing eating xyz food.

One such thing that I was missing was a cake. And a quick one at that. Before keto, whenever I felt like munching or having a snack, I would grab some chips or cookies or even a banana. But I am not allowed any of those things now. I felt like I needed to find something that I can grab as and when I wanted.

And then I found some mug cake recipes on pinterest and it struck me that this is exactly what I want – a quick fix!

And then came this recipe as a blessing. It takes less than 90 seconds in the microwave and less than a minute for the prep. Believe me, keto or not keto, if you have these ingredients at hand, please give this a try!

It is so delicious. My mind was blown when i had this for the first time. And it has become my frequent and favorite mug cake recipe. It is super moist, and soft and very customisable. Since I love bananas (and can’t have them), I use banana essence in these mug cakes. You can use any flavor you want.

You can add or omit chocolate chips, chopped nuts if you like!

Without wasting any more time, let me share the recipe of this amazing 90 second mug cake with you all.

  • Very tasty. Satisfied my sweet tooth while I’m reducing carb intake. Substituted regular flour for almond.hmmm I wonder what else I could have used. Will make this again using different flavors. Good one!

    • Sure! I am so glad you found this recipe and liked it! I am in love with this one too. My go-to for days when I crave something sweet. You can add chopped berries, walnuts, caramel bites or even sugar free sprinkles! Have fun!

      • Hi Cynthia! I am glad you stopped by. I do not use regular flour at all for all my low carb recipes. In this recipe also, I used almond flour.

    • Hello Sandy! Thank you for stopping by! This cake is indeed my go-to. I have updated the nutritional info in the post itself. Please do check it out. At 5g net carbs, I think this cake is pretty good!

  • Thus was very good. Being diabetic, it was nice to have something to satisfy my sweet tooth. I have made it twice and will keep on making. Thank you

  • I love vanilla cake so I’m very excited to add this to my keto recipes! Just wondering if you have any keto recipes for frosting (my guilty pleasure)! Thanks!

    • Hi Dayna! I have never tried it with coconut flour but I guess it would come out very different if you do that. Coconut flour is a lot drier than almond flour. So the mug cake wouldn’t be as soft as this one if you use coconut flour.
