Here’s an easy, yummy, kid-friendly muffin recipe for you to try, or get bold and learn to substitute flax into your family’s favorites (see below for details)!

How to Substitute Flax in a Baking Recipe

  • Take out some of the fat in your recipe – butter, shortening (eek!), oil, whatever. I usually have been very safe taking out 1/4 cup of fat, whether there’s 1 cup or 1/2 cup in the original recipe.
  • Replace that with 3x as much flax meal. If you delete 1/4 cup of fat, add 3/4 cup of flax. That seems like a lot, but it always works!
  • You may need to store your baked goods in the fridge – I found they go bad faster with flax involved.

Good luck and enjoy!

  2. I know I’m late on the ball, since you posted this a year ago, but I’m a recent subscriber and catching up. I can’t remember how I got to this recipe, but I just tried it today– used raw sugar and coconut oil and added a big handful of dried cranberries. It’s soooo good! I’ve made banana muffins for years, and I think these are the best ever! Thank you for posting a year ago. So glad I could still access it!

  4. Do you have a soaked version I this recipe? Also, can I substitute honey for huge sugar?

    1. Katie Kimball @ Kitchen Stewardship

      I’ve never soaked this one, partly because I’d have to rely on the oil and bananas as the “liquid” and I’m not sure if it would “count” i.e. actually lower the phytate count in the flour.

      I have used honey, 1/4 cup instead of the 1/2 cup sugar. 🙂 Katie

    I tried these today, adding chocolate chips. They were really good and perfectly sweetened.

    Thank you for the tips about flax too!

  8. I’ve always been confused about something and I’m really hoping you can help clear it up….

    Is it okay to heat flax seeds? I’ve tried to find some information on it but what I’ve found seems so conflicting???? Most sites say that you should definitely not heat flax seed oil as it becomes rancid but what about in a recipe like this where you’re just using the ground seeds?

    1. Lucy,
      You’re right about flax oil; it definitely should not be used for cooking. However, the internal temp of these muffins in the oven should only get to about 150-170, which won’t damage the fats in the flax. I think. There are so many recipes for baking with flax, and I don’t think I would have missed warnings about baking with flax. Hope that helps! 🙂 Katie

  10. Hi this looks delicious. I’ve tried many recipes on your site. Wondering: if we wanted to use molasses what the ratio of substitution would be here? Or honey…


  11. Christy @ Raising Knights

    Love your site! I’m making your Tuscan Bean Soup tonight.
    Coincidentally, I recently posted a similar recipe that I have upgraded over the past few years. Great minds think alike! 😉

  13. We made these for breakfast this morning and added some chopped raw almonds (since I was out of walnuts) and unsweetened coconut chips. They were a hit with everyone, even my husband who doesn’t like bananas!

  14. I GOT BOLD!!! I made oatmeal cookies today with fresh ground flax seed. I figured that it would be as easy add with the oatmeal. I also cut a 1/4 c of brown sugar and used honey instead of white. I even did it with a mix of whole wheat flour and white. I’ve been looking for ways to make treats my dad loves a little healthier verses him buy those crappy cookies from the store. He LOVED them! He took a bit and he said “Oh man I’m going to have to ration these – these are too good!” You’ve got me so pumped to do new things in the kitchen!

  15. Thanks for the reply! I did try the apple cinnamon ones with applesauce but I actually also added 1 & 1/2 tsp of ground cinnamon, 1/4 teaspoon ground ginger and 3/4 cup of brown sugar (instead of white sugar). They were delicious! I think my husband would have preferred that they be *slightly* sweeter but he thought they were great anyway. Maybe next time I’ll try it with the white sugar instead or just maybe a little more brown sugar. Thanks for the help! 🙂

  16. I love your recipes on here! I found this site because I was looking for a good recipe for whole grain tortillas and I’m so glad I did!! I love this banana flax recipe but I was wondering if it’s possible to change it to apple cinnamon or blueberry? I’m kind of new to cooking and baking etc so I’m not the best at substituting…

    1. M,
      I bet you could! You would need to compensate w/an equal amount of wettish stuff for the lack of bananas. I would try 1 cup applesauce and add 1 tsp. cinnamon. For blueberries, maybe the cup applesauce anyway and then add blueberries? Or just banana blueberry. Let me know if you try it; I love adding transformations to my recipes!
      🙂 Katie

  17. Thanks for this recipe! I am going to use it for my Share My Recipe Sunday today! I have been working on adding in Flax seed myself this thank you.

  19. this is a wonderful discovery! the muffins sound great but i love the tip re: flax substitution. We use ground flax, sprinkling it on yogurt, in smoothies, in oatmeal, but in a hundred yrs I’d not have thought to substitute for fat. thanks so much I’m thrilled to have found you thru Mouthwatering Monday!

    1. Welcome! So glad I could be of help; I hope the substitution works well for you. Come back anytime! 🙂 Katie

    This is such a great idea. I didn’t know anything about flax. We’re trying hard to curb our terrible culinary habits and to reduce fat and sugar. Thanks so much!

  21. These sound delicious..we always have lots of bananas in the house! Happy Foodie Friday! Have a great weekend ~ Susan

  22. Thanks for the recipe and the tip about substituting flax for fat. Have a wonderful day.
