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.

Grab’n’go 5 minute flaxseed muffin in a mug!

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 an ovenproof ramekin or muffin tray.

Bake your recipe at 180C (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-hole mini muffin tray to make small size flaxseed muffins for your week.

Instructions

  • 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.

  1. Hi Carine! Love your recipes. I saw this recipe in your round up of 45 vegan keto recipes (I cannot eat eggs). I cannot see a vegan version. Apologies if I am missing something, I would love to make this.

  2. 5 stars
    Wow – these were so yummy! When I entered them into My Foods in Easy Diet Diary they still show as 11g carbs even though I entered the Fibre of 8.7g…. What should I be counting towards my Carb count?

    • On keto you count net carbs, not total carbs. Net carbs equal carbs minus fiber minus sugar alcohol. So here its 11.7g – 8.7g so 3 g net carbs. Your app seems to count carbs not net carbs.

    Love this recipe and is so easy. I made into 2 small muffin and micro-wave for 30 seconds. I came perfect. Bake once eat twice.

  4. 5 stars
    I haven’t made this recipe yet, but I’ve made others and they are delicious. I would like to make this one, but can’t eat eggs. Is there an egg replacer you can recommend?

  5. 5 stars
    This is such a great base recipe! I’ve made so many different muffins with this, and they always turn out delicious! I do have a question though. Can these be meal prepped ahead of time (ie mixing everything but the egg together on weekend, using throughout the week)? I love this recipe but find that I’m a bit slow with the prep so don’t have time on weekdays to make it 😞✌🏻

    • I never try that but I am pretty sure you can make ahead the muffin batter, store in the fridge in s sealed container and bake the next day. But also the baked muffins store very well and freeze too so maybe bake 2 batch on the weekend and freeze the baked muffins. Simply thaw one muffin the day before breakfast. I hope it helps, Enjoy, XOXO Carine

    This is so delicious. Tastes like a bran muffin. I’m eating it plain now, I didn’t use the add ins, just sliced it in half warm with butter. This is my new go to breakfast! I was so sick of eggs on keto. Thanks so much for a wonderful recipe. Very excited to play with the variations! This is one of my new favorite sites for Keto!

    This is super yummy. Thank you. Only difference was I used a flax chia mix. No plain ground flax on hand. This recipe is so versatile too. My husband wanted blueberries and blackberries instead. So we left out the chocolate chips and substituted those berries for the raspberries. This one is a keeper!

  8. 5 stars
    Wow, even though I left out the raspberries and chocolate chips, it tasted almost like banana muffins. I love it Thanks Carine.

  9. 5 stars
    I just made this with 2 tbsp of frozen blueberries. Tastes like a blueberry muffin. Great recipe!

    • It’s a great idea! I love a good blueberry muffin too. Enjoy the recipes on the bog, XOXO Carine

    This is really quite delicious. I lowered the fat content by using egg whites and replaced the coconut oil with greek yogurt and added 1 Tbl unsweetened coconut flakes. It’s become my go to breakfast.

  11. 5 stars
    I made this for breakfast this morning and got one bite out of it before it was eaten by my 4 year old and 15 month old! It was so yummy! We will definitely be making this again!

  12. 5 stars
    Just made the flax meal raspberry and chocolate chip muffins. No flaxmeal in the cupboard so used almond meal. These were delicious!

    • That is good to know the recipe work with a different keto flour ! I always use flaxmeal in this one but thanks for sharing your tips. Enjoy the blog, XOXO Carine

  13. 5 stars
    I can’t express how much I LOVE this recipe! The texture, the flavor, and the fact it more than fills & satisfies while staying within KETO macros is perfect. I made it in a good sized mug – which it nearly filled! – and was left with just enough room to top it with a dollop or two of my KETO cheesecake fluff. The fact that recipe is quick & easy

    • I LOVE the ketto cheesecake fluff on top! It must have been even more delicious. Enjoy the keto recipes on the blog, XOXO Carine.

    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.

    • Thanks for sharing yor recipe adaptation, I am sure plenty will try. Enjoy the blog recipes, XOXO Carine.

    • 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
