Flax Muffin in a Mug in a Minute! (Low Carb and Gluten Free)

This is classic recipe from the low carber forums and is a fabulously fast and easy recipe to make.  It is perfect for a quick, healthy and filling breakfast.   It is low carb and gluten free too! 

   Also a good way to get some flax into your diet.  The muffin tastes like a sweet wholemeal muffin with a dash of cinnamon.   Even the chief taster who is not a flax fan likes this.   You could add chopped nuts or fruit to this and even a few spices to your liking.  Play around and make it your own! I like to add coconut and berries to mine…just delicious!


The only drawback of this recipe is that you need to make it in the microwave.   However, it is fun to watch it quickly rise in the cup whilst cooking in the microwave…but that’s probably just the inner child in me coming out again…  The time it takes to cook will depend on the power of your microwave.  Cook for a minute, check it and zap it for a few seconds more until it is firm and cooked.  It makes a great breakfast or snack on the go!


1 tspn butter

1 egg, beaten well

1/4 cup ground flaxseed

1 tspn ground cinnamon

1/2 tspn baking powder

2 tspn Erythritol or sweetner of your choice  (maple syrup is lovely! Honey good too!)

Other flavourings of choice (optional)..although can I recommend blueberries and unsweetened desiccated coconut….


  • Lightly grease the inside of a mug with a dab of butter.
  • Add the tspn of butter to the mug and microwave for a few seconds to melt it.
  • Remove the mug from the microwave, add the remaining ingredients and mix well.
  • Pop the mug back into the microwave and cook for about 45 seconds to a minute or more, depending upon your microwave.
  • When the muffin is done, turn it out onto a plate.
  • Eat and enjoy!

    I love the cream cheese suggestion! I made my first muffin this morning and love it. The photo makes it look a little eggy, but it does not taste of egg at all. I added 2 drops of maple extract. Very thankful for a high fiber option as this is my biggest challenge since going keto.

        Angela, It just got better! I used cardamom and cinnamon with a dash of anise seeds. I also put a dollop of cream cheese in the center as suggested by another Julie! It is so good!! How can I send you my photos?

      I’d bake it at about 350F degrees for 10-15 minutes.

      You might be looking at total carbs, not net carbs. The fibre needs to be subtracted and flax seed is very high in carbs, usually netting about 1g net carb per serving.

    This was really good! I did have to make a few modifications. I’m dairy free so I used coconut oil instead of butter. I only put in a half tsp of cinnamon and added a quarter tsp of nutmeg. I don’t have any sweetner in the house so I used a Tbsp of my Perfect Keto vanilla protein powder. It was just what I needed. And my first mug cake. Thanks so much for the recipe. It will be added to my weekly breakfast rotation!

    I just stirred one of these up for breakfast. I left out any sweetener, sank about 1 T of cream cheese in the middle and added a small handful of wild blueberries on top. Seems pretty decadent!! 🙂

        It really was, and I have to tell you that I ended up getting caught up in work all day and didn’t ever get to eat lunch. I didn’t even notice until about 4 o’clock in the afternoon, so all that fat and fiber kept me full for a good long while. 🙂
