What’s A Flaxseed Muffin?

A flaxseed muffin is similar to a classic muffin, but the batter is made with ground flaxseed instead of other flours.

Flaxseed is one of the flours with the lowest net carbs because it contains a huge amount of fiber.

As a result, flaxseed muffins are lower in carbs than regular muffins but still taste great!

How To Make Flaxseed Muffin In A Mug

Are you sometimes craving a good bakery-style muffin? I do, and I like to fix my food craving very quickly.

That’s how I created this simple flaxseed muffin in a mug recipe. It’s a very healthy recipe made of a few simple low-carb ingredients.

I baked my muffin in my microwave for an even faster result, but you can bake yours in a regular oven if you like. It simply takes a bit longer.

That’s why I recommend cooking yours in a mug in the microwave if you crave something sweet now!


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. It’s also 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 a healthy oil full of antifungal and antibacterial properties without saying that the flavor it adds is the best!
  • Vanilla extract
  • Cinnamon
  • Egg – don’t replace the egg in this recipe. It won’t work! Trust me, I tried, and there’s 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’s a natural sugar-free sweetener, a combo of erythritol and stevia. Check out my review of keto-friendly sweeteners to learn more!
  • 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 with any kind of chopped nuts like walnuts, almonds, or pecan. If you don’t have chocolate chips, you can make your own sugar-free chocolate chips.

Yes, you can make these quick flaxseed muffins in a mug as a delicious on-the-go breakfast!

My technique is pretty easy. I am adding a muffin paper cup into my mug.

After it cools down for 2 minutes, you can easily unmold your muffin, and have it on the go!

Bakery-Style Flaxseed Muffins

It’s a moist bakery-style muffin filled with raspberries and melted sugar-free chocolate chips. You won’t believe this recipe is sugar-free and contains only 3 grams of net carbs.

It’s a perfect post-workout muffin loaded with 12 grams of protein. This will keep you full until your next meal without a doubt!

Baking Flaxseed Muffins In Oven Or Microwave

I love to bake my flaxseed muffin in a mug in the microwave for 1 minute 30 seconds.

However, you can also use your oven. Simply make sure you are using an ovenproof ramekin or muffin tray.

Bake your recipe at 350°F (180°C) 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-hole 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.

    • 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.

    • Thank you! It is a very cheap ingredients that you can find in most supermarket. 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’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 love baking and I struggled with pre diabetes after baby 1. This blog is about sharing my healthy baking option to enjoy some bread and desserts without impact my blood sugar level too much. It makes me very happy that those simple recipes helps you too. I will think about that flax meal scone recipe, great idea. 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 an airtight box for months in the pantry. You can look at my flaxseed wrap recipe video you will see how I blend my seeds. Enjoy the recipe. XOXO Carine.
