It is a very healthy recipe made of few simple low carb ingredients. I baked my muffin in my microwave for a even faster result BUT you can bake yours in a regular oven if you like.

So, this is what you need to make a delicious bakery style flaxseed muffin in a mug:

  • Flaxseed meal – flaxseed is high in fiber and omega 3, plus it is very low carb so a great flour base to create healthy low carb muffins
  • Coconut oil – you can use any vegetable oil in this recipe but coconut oil is an healthy oil full of anti fungal and antibacterial properties without saying that the flavor it adds is bomb!
  • Vanilla extract
  • Cinnamon
  • Egg – don’t replace the egg in this recipe it won’t work ! Trust me I tried and there is no great egg free option for this recipe.
  • Baking powder – or 1/4 teaspoon baking soda
  • Sugar free crystal sweetener – my favorite sweetener is this one, it is a natural sugar free sweetener, a combo of  erythritol and stevia
  • Raspberries – optional, you can simply make the recipe without fruits or use blueberries, lemon zest or orange zest to add healthy low carb flavors
  • Sugar free chocolate chips – optional you can replace this by any kind of chopped nuts like walnuts, almonds or pecan.

Oven or microwave ?

I love to bake my flaxseed muffin into a mug in the microwave for 1 minute 30 seconds. However, you can also use your oven, simply make sure you are using a oven proof ramekin or muffin tray. Bake your recipe at 180 C (350F) for about 12-15 minutes or until a skewer inserted in the middle of the muffin come out clean. You can also quadruple the recipe to make a larger batter and fill a 12 holes mini muffin tray to make small size flaxseed muffins for your week.

Optional ingredients- Raspberry Chocolate Chip Flax Muffin


  • In a bowl, whisk egg, oil and vanilla together. Set aside.
  • Stir in the dry ingredients: flax meal, baking powder, cinnamon and sugar free sweetener. 
  • Stir in the optional ingredients, raspberries and chocolate chips are my favorite.
  • Transfer into a mug - mine was 2.5 inches height that is the minimum required to avoid the muffin to overflow. 
  • Microwave on high for 1 minute 30 seconds. 
  • Wait 1 minute before eating to avoid burning yourself.
Sweetener: you can also use stevia drops, adjust regarding taste usually 1-2 drops are enough. 
Flavors idea: other delicious flavors are blueberries/lemon zest, walnuts and orange zest, sugar free chocolate chips

    Hi – All these recipes I’m reading sound great.
    For this one, do you have time and temperature instructions for baking? I’d love to make a bunch for the week. Thanks!

    I just made this.blove the idea of using flaxseed. It got huge and puffed up. It has a slight aftertaste. I didn’t put berries or chips in. And I put in baking side and baking powder by mistake, maybe that was the aftertaste? I used swerve slso.bNext time I’ll put in some chocolate chips and a few chopped nuts. Or maybe cream cheese frosting.

    • Indeed flaxseed are slightly bitter and if you don’t add any choc chips or berries are recommended there is nothing to mask this. Plus, you used baking powder that increased bitterness I am sure you will love it with the choc chips and cream cheese frosting next time ! Enjoy, XOXO Carine.

    I’m not doing keto, but I use flaxmeal for fiber, so the recipe looked interesting. I tried it with egg white only and substituted the oil for one teaspoon water, and it turned out great with less fat, for those who don’t need the extra. Thanks for posting. I’m going to try those avocado peanut butter chocolate cookies next.

    • This is so clever! I never thought about that it is such a great idea to have those muffins on hands for snack time. Talk to you soon, XOXO Carine

    • Yes you can grind whole flaxseed into meal in a blender but you need a very powerful blender ! If yours is not powerful enough the meal is too thick and it doesn’t absorb liquid as well. You can easily buy flax meal from the store, it is cheap and it is usually the same price as flaxseed. Enjoy the recipe. XOXO Carine.

    • Not really, like any food baked in the microwave it must be eaten within 30 minutes or the texture harden. You can also bake this recipe in the oven and it will last 4 days. Enjoy the low carb recipes on the blog. XOXO Carine.

    • I am so happy you find my blog. I love flaxseed too and I have got few good recipe using flax meal, you should try my flaxseed wraps too. Enjoy the recipes on the blog. XOXO Carine

    Love the recipe! Made as is the 1st time as is & loved it. Just made it with half almond flour & half flax. Added almond & lemon extracts, poppy seeds & raspberries. Cooked in microwave, cut in half & toasted with cream cheese. Yum! Thank you for this wonderful keto breakfast treat.

    • What a lovely idea! I will give it a try next time, I love lemon and poppy seed combo too! Enjoy the low carb recipes on the blog. XOXO Carine.

    I’m so glad I found your blog…and have you based in NZ like me. I got Gestational Diabetes with my first child that did not go away. I have been Type 2 for 10yrs now and have gotten used to either going without treats, or feeling guilty when I eat something I probably shouldn’t! Since finding your blog over the weekend, I’ve tried 5 of your recipes. This one is my current favourite! I love cooking with flax meal as it’s so cheap and easy to make your own. Any chance of developing a flaxmeal scone recipe? I haven’t been able to find one online yet!
    Thank you so much for this blog and creating diabetic friendly recipes that use simple ingredients. I’m excited to bake again and not feel guilty for eating it!!

    • Hello from Auckland ! Thanks for this lovely comments, I can’t believe you already made 5 recipes from the blog, that is so amazing.

I recommend you try the flaxseed mug cake, it is very simple, cheap and a delicious fulfilling breakfast or dessert when you need to fix your sweet craving in a minute! Enjoy the blog. Talk to you soon, XOXO, Carine.

    Perfect breakfast option or really anytime! I made one with frozen cherries and chocolate chips. I’m seriously amazed at how easy, nutritious and delicious this recipe is. I didn’t add a sweetener but I did spread butter on the baked muffin. Thanks for creating and sharing this awesome recipe. 5 stars for sure! Cardamom and cinnamon would have been good with the cherries. Or even a savory option with finely choppped vegetables.

    • WOW! I am surprised that you already made it 🙂 This is so amazing to have you on the blog, testing my recipes and adding such great ideas ! I didn’t try the savory version but that is a delicious idea ! Thanks again for your lovely comment and thanks to YOU for being there, testing my creation and sharing your feedback! Enjoy the blog recipes. XOXO Carine.

        • Sure! I d this all the time, make sure you add a large amount of flaxseed to cover the blade, blend 30 seconds, open, mix with a spatula and repeat until thin enough. Then store you flaxseed meal in a airtight box for months in the pantry. You can look at my flaxseed wrap recipe video HERE you will see how I blend my seeds. Enjoy the recipe. XOXO Carine.
