Ingredients (makes 1 serving)

Tips for substitutions: If you want to make the recipe nut-free, use 1 tablespoon of coconut flour instead of 2 tablespoons of almond flour. If you don't have coconut flour, you can use 2 tablespoons of finely shredded desiccated coconut instead.

Too "eggy"? Although I like this combination, some of you may perceive it as too "eggy". You can try the following: use one egg, double all the dry ingredients and add 1/4 cup coconut milk, almond milk or cream. This mixture will make 2 mug cakes. Instead of the listed sweeteners, you can try other healthy low-carb sweeteners from this list. The reason I'm using both Erythritol and stevia is to mask the aftertaste some of the sweeteners may have.

A fun way to learn about healthy low-carb eating!

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Thanks for the recipe. These are really tasty! I substituted the almond flour for coconut flour as per your instructions. Only objection is the oven cook time, which was more towards 20-25 minutes (after 15 minutes I lowered the temperature as the sides were getting brown and the middle was only halfway cooked). I used a standard ramekin.
Will definitely make these again!


Thank you for your insights Diana! I suppose it depends on the size of the muffin pan that will determine how well it cooks in the centre.


Just made this for the first time!  Wow! It is awesome and I will remember it for when I need a dessert as well.  I used butter where you gave me a choice and coconut milk (first time for this too) where you gave me the choice and also the dark rum. It is actually a huge portion and I will save half for later.  Thank you Martina!


Thank you Carol! 😊


Too eggy anything? Add vanilla to counteract the taste of those yolks....even the smell of them! Even to vanilla whey protein powders....they all smell like rotting begs for more vanilla. Even when baking with whey...always, always add vanilla. No, your baked goods will not have a strong vanilla will be just right!
Try! You will see! When using lots of eggs in LCHF baking, use vanilla!

Thanks for the great tips Gladys! 😊


I only have coconut flour right now.  Could I substitute coconut flour for the almond flour?


Yes, you can. Please, see the "substitutions" below the ingredient list. I hope you like it!
