Flourless Zucchini Muffins

I’ve updated this recipe for low-carb and gluten-free Flourless Zucchini Muffins so it now makes six larger muffins that are perfect for breakfast! You can double the recipe to make 12 large muffins if you have lots of zucchini to be used!

I first made these Flourless Zucchini Muffins more than ten years ago, and then I kind of forgot about the recipe even though people would comment on it now and then. And then earlier this summer I made a batch of the original recipe for these muffins with Kara and truthfully, we decided they could be improved! (For anyone who was a fan of the original version, just follow that link to get it.)

The original muffin recipe made six muffins, but when we tried them in the size of silicone baking cup I use for my muffin recipes now, the muffins were small and too flat. And although the flavor was definitely not bad, we thought it could be better. 

We made a new version that doubled most of the original ingredients for a larger muffin, used a bit more sweetener (although these muffins are still not super sweet), slightly increased the amount of cinnamon, and omitted the small amount of oil which wasn’t needed for a muffin made with almond flour. And Kara and I are both not great at baking (although she’s better than I am), so we had to make them over and over to get the version we’re sharing with you here. All the not-quite-the-one versions were still gobbled up by the kids, but when we tested this final version and both Kara and I said, “These are really good” we knew we had a winner.

As you can see I like to cut my breakfast zucchini muffin in half, heat for about 30 seconds in the microwave, and enjoy with a pat of butter! And after I ate a muffin this morning I picked one yellow summer squash and three large zucchini from my tiny garden patch, so I know there must be other people looking for ideas to use zucchini; enjoy!

What Size Silicone Baking Cups did I use?

I have three sizes of silicone baking cups. But my middle size (that the manufacturer calls Jumbo) is 3.5 x 2.25 x 1.6 inches and holds 2/3 cup, and that’s the size I use for almost all my Low-Carb Muffins and Breakfast Muffins. That’s the baking cups I used to make six large muffins with the updated version of this recipe.

However you can definitely make these flourless zucchini muffins with different sized baking cups and adjust the cooking time to be a little more or less, so don’t be afraid to try that.

How to Make Flourless Zucchini Muffins:

(Scroll down for complete recipe with nutritional information.)

  1. Preheat oven to 350F/175C. If Almond Flour (affiliate link) has been in freezer, let it come to room temperature. 
  2. Wash and dry outside of zucchini and grate with large side of a hand grater or with a Food Processor (affiliate link). Grated zucchini keeps well in the fridge, so do extra if you have a lot of zucchini.
  3. Put the grated zucchini inside cheesecloth or a kitchen towel and squeeze out the excess water. 
  4. Measure out 1 1/2 cups of grated zucchini. Coarsely chop pecans, or any nuts of your choice.
  5. Put 2 eggs and 2 egg whites into small bowl. Use a hand mixer to beat until the mixture has tripled in size, about 2 minutes. 
  6. Add Golden Monkfruit Sweetener (affiliate link) or sweetener of your choice and buttermilk to the beaten eggs. 
  7. Measure 2 cups almond flour into bowl, add salt, baking soda, and cinnamon, and combine.
  8. Stir liquid mixture into the almond flour mixture. Stir just enough to barely combine.
  9. Gently fold the zucchini and pecans into the batter, again stirring only enough to barely combine.
  10. Spray muffin cups with non-stick spray. Divide the batter into 6 baking cups.
  11. Bake muffins about 45 minutes, or until top is browned and toothpick inserted into the center comes out clean. (I was surprised they took that long, but I really did bake them for 45 minutes.) 
  12. Try to be patient and let them cool on a rack for at least 20 minutes or a bit longer before you eat them.

Flourless Zucchini Muffins

Flourless Zucchini Muffins

Yield 6 muffins
Prep Time 30 minutes
Cook Time 45 minutes
Total Time 1 hour 15 minutes

These Flourless Zucchini Muffins are also low in net carbs and gluten-free.

Ingredients

  • 1 1/2 cups grated raw zucchini
  • 1/2 cup chopped pecans
  • 2 cups blanched almond flour
  • 1/2 tsp. salt
  • 1 tsp. baking soda
  • 1 1/2 tsp. ground cinnamon
  • 2 large eggs
  • 2 egg whites
  • 1/2 cup + 2 T Golden Monkfruit Sweetener (see notes)
  • 2 T buttermilk (see notes)

Instructions

  1. Preheat oven to 350F/175C. If Almond Flour has been in freezer, let it come to room temperature. 
  2. Wash and dry outside of zucchini and grate with large side of a hand grater or with a Food Processor (affiliate link). Grated zucchini keeps well in the fridge, so don't be afraid to do some extra to make muffins another time.
  3. Put the grated zucchini inside cheesecloth or a kitchen towel and squeeze out the excess water. (Zucchini doesn’t have to be completely dry but squeeze until you have removed most of the water. This will take a minute or two.)
  4. Measure out 1 1/2 cups of grated zucchini, loosely packed into the measuring cup.
  5. Coarsely chop pecans, or any nuts of your choice.
  6. Put 2 eggs and 2 egg whites into small bowl. Use a hand mixer to beat until the mixture has tripled in size, about 2 minutes. (Don't beat it until the eggs begin to form peaks.)
  7. Add Golden Monkfruit Sweetener (affiliate link) or sweetener of your choice and buttermilk to the beaten eggs. 
  8. Measure 2 cups almond flour into bowl, add salt, baking soda, and cinnamon, and use a fork to combine.
  9. Stir egg mixture into the almond flour mixture. Stir just enough to barely combine.
  10. Gently fold the grated zucchini and chopped pecans into the batter, again stirring only enough to barely combine.
  11. Spray muffin cups with non-stick spray. (If you're not using the same size silicone baking cup, you might get more than six muffins.)
  12. Divide the batter into 6 baking cups, starting with 1/2 batter in each and then adding any extra to make muffins cups equally filled. Cups will be about 2/3 full.
  13. Bake muffins about 45 minutes, or until top is browned and toothpick inserted into the center comes out clean. (I was surprised they took that long, but the batter is quite moist and dense and I really did bake them for 45 minutes.) 
  14. For these muffins it’s important to cool them a bit longer than muffins made with wheat flour, so try to be patient and let them cool on a rack for at least 20 minutes or a bit longer before you eat them.

Notes

Almond Flour (affiliate link) is widely available, and if you shop at Costco you can probably find it there! I used Golden Monkfruit Sweetener (affiliate link); use any sweetener you prefer. You can probably use milk or cream instead of buttermilk, although I haven't tried that.

Flourless Zucchini Muffins

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
The almond flour used in these Low-Carb and Flourless Zucchini Muffins also makes them gluten-free, and with the Golden Monkfruit Sweetener (affiliate link) I used they’re low in carbs. Flourless Zucchini Muffins aralso a good choice for the original South Beach Diet, since almonds contains “good fat” and are a healthful ingredient; however, nut flours are a limited food so these muffins would be too calorie-dense for phase one of South Beach.

  1. These are fab! I used coconut milk instead of buttermilk. Love them! Thank you!!

  2. Very interesting; I haven't heard about mesquite pod flour before.

  3. Wonderful recipe! I substituted with mesquite pod flour instead of almond flour and xylitol instead of Splenda…mesquite gives a deliciously smoky flavor, definitely a nice variation!

  4. Natasha, so glad you liked the muffins!

  5. These muffins are fantastic! It's a good thing I doubled the recipe because my boyfriend couldn't get enough of them 🙂 Thanks so much!

  6. I must get my hands on some almond flour!

  7. These were great, lovely recipe. My husband is an energy conservation fanatic so I made these in my new energy efficient toaster oven that he bought me. They turned out perfect. I think he liked them even more because I used the new toaster oven that "he" bought online (big step for him).

  8. Yippee! I'm so happy to see a gluten free muffin recipe! This will work marvelously for my g/f girl, and I don't even have to camouflage the zucchini because she likes that veggie! YUM!

  9. I love the new header and your zucchini muffins look incredible. I am always intrigued by your unique slant on food. I don't see you use splenda that often, but I could be wrong about that. I have read that it can still impact blood sugar in the same way as sugar but I'm not sure I agree with it. I try not to use it as I feel better when I don't but I do feel it's a much better alternative than white sugar. I don't bake with it – I use agave which can be a debate in and of itself. At times I use it in my coffee if I'm somewhere and the coffee is so bad that I can't drink it black.

    I am still getting zukes from friends as they are growing in full-force in Texas and made some muffins last week. They were great.

  10. Elana, thanks and can't wait to meet you.

    Julie, they aren't chocolate, sorry. Does look like it, doesn't it?

    So glad people everyone is liking the sound of these. I did like how they turned out (and there's a big zucchini waiting in the fridge at home to make more!)

    Mike, I didn't think of that on the header, will ask Rand what he thinks. Thanks for the suggestion; glad you are enjoying the blog.

  11. Kayln, you and I must be on a similar wavelength! I posted some gluten-free, almond flour zucchini muffins/cupcakes on my blog Wednesday! They're decidedly different than yours, but yours have such a lovely "crust" on the top, I'm intrigued. They look yummy!

  12. For anyone reading the comments – these muffins are delicious!

  13. This blog is such a goldmine for us – my husband's diabetic, and I've "cooked him" into perfect control without insulin (well, and walked him) but I miss baking terribly. This whole almond flour thing opens up all kinds of possibilities.

  14. I love that these don't seem to be ridiculously sweet. They probably make for a great breakfast because of that! Also so much nutty goodness.

  15. oh these sound absolutely fabulous!!! Totally need to make these 😀

  16. These look so good. I love baking with that almond flour. I hope you brought some of these with you to Blogher, I'm so hungry now!

  17. re: Thanks to my uber-talented brother Rand for the new blog header on Kalyn's Kitchen!
    I like the new Header, but I'd change the order… right now it reads, "Cook, Eat, Lose Kalyn's Kitchen Weight, Repeat"!! LOL! Perhaps change the 4th & 5th blocks?
    Love the site, love your blog. Enjoy "Frisco"!

  18. Ooh, these look fab! I'm always looking for new (chocolate) ways to use zucchini.

  19. OH wow. These look lovely. I must give them a try 🙂 Thanks for the recipe!

  20. Yours are gorgeous! Great photo 🙂
