What is rhubarb?

Rhubarb is a tangy vegetable with stems that are typically tart and red. The leaves of rhubarb have little to no flavor and are not eaten, but the cooked or raw stalks can be used in pies, jams, tarts, or even wine. Rhubarb grows in bunches in spring, but they’re easy to find in grocery stores as well.

How to store rhubarb

If you look through the produce in grocery stores from spring even into summer, rhubarb is often available even if you don’t have your own in your garden.

The best way to store it that I’ve found involves a couple of tips. If you leave the rhubarb completely unprotected in your fridge, it will cause its exposed ends to dry out and become limp within just a few days due to water loss. 

On the other hand, sealing the stalks tightly in zipper-lock bags or plastic wrap causes them to turn limp. This happens because airtight storage traps the ripening hormone ethylene. It activates enzymes that break down and soften the cell walls in many fruits and vegetables.

If you store rhubarb in foil, it will stay fresh for two weeks or even longer. The key is to wrap the stalks snugly enough so that they don’t dry out. Also, don’t crimp the ends of the foil too tightly off from air circulation so that the ethylene gas can escape. 

Therefore, wrap the rhubarb tightly enough to make a neat bundle, but don’t tightly crimp the edges.

Isn’t it beautiful? I love rhubarb!

What else can you do with rhubarb?

  • Make keto rhubarb muffins! 
  • Use it in pies, tarts, or bars
  • Boil the stalks with your desired sweetener to create a syrup for your keto desserts and drinks like keto pudding, meringue shells, custard sauce…or as an ice cream topping. You could also use this syrup in cocktails or mocktails too! 
  • Mix it into a keto smoothie!

Are rhubarb muffins keto?

Rhubarb is low carb! It’s keto-friendly too. How many carbs are in rhubarb? A half-cup serving contains about 1.7 g net carbs and only about 13 calories. 

The keto rhubarb muffins are delicious and easy to make. They’re a great breakfast or as an afternoon snack on keto diet. The recipe is simple enough that even if you’re not much of a baker, this could be your new go-to low carb recipe for any summer brunch or breakfast. I highly recommend making these keto rhubarb muffins – just that rhubarb flavor sends me back to the summers of my childhood.

How good Mrs. West could have written such books and collected so many hard works, with all her family cares, is still more a matter of astonishment! Composition seems to me impossible with a head full of joints of mutton and doses of rhubarb.

🔪 Instructions: how to make keto rhubarb muffins

You know those muffin cups that you always seem to have in the back of your cupboard, just waiting for a chance to show off their true colors? Well, today is finally the day; go ahead and whip out 12 silicone baking cups or other liners before preheating the oven to 325 degrees Fahrenheit.

Next, place the cream cheese, eggs, and vanilla in a blender and blend on high speed for 30-40 seconds or until well combined. If you don’t have a blender or just don’t want to use it, this can also be done in a standing mixer.

After that, place the almond and coconut flours in a large bowl along with the baking powder, salt, and sweetener and whisk them together evenly.

Then mix the wet ingredients with the dry and combine with a spatula or mixer.

Now it’s time for the rhubarb! In order to prepare it to bake in the muffins, wash and then dice it into small pieces. Mix the rhubarb into the batter until it’s all well-incorporated.

*Batter Tip: The muffins pictured are made exactly to the recipe in Colorado, which is a high-altitude, dry area. As ingredients and locations do vary, if your batter seems thin or runny, add 1-2 extra tablespoons of coconut flour. Mix it in at the end, spoon the batter in the muffin cups, but let it sit for about 5 minutes for the coconut flour to soak up the extra moisture from the rhubarb or other ingredients.

💭 Top tip – keto rhubarb muffins recipe

One of my favorite tips to make muffins sounds a little odd at first. I like to use an ice cream scoop to spoon the batter into the muffin cups.

What?! An ice cream scoop?

Yes! The scoops with a trigger are the best and are a quick and easy way to get the muffin batter into the cups.

Scooping the batter into muffin cups

Therefore, once the batter’s ready, fill the dozen muffin cups about 3/4 full until all of it is evenly distributed.

This next step will really add to the taste and texture of the muffins, so don’t leave it out! Take out a small bowl and stir together the cinnamon and 3 tablespoons of granulated sweetener. Then sprinkle the mixture evenly over the top of the muffins.

This is a great task for kids, and my son is always eager to help with the topping. Don’t worry too much if they get some on the pan instead of on the muffins. They’ll still turn out fabulous and kids love to help!

⏲️ Baking time

Bake at 325 degrees Fahrenheit for 25-30 minutes or until a toothpick comes out clean.

Rhubarb has a tart, fruity flavor that is perfect for muffins. Let these oven-baked treats cool off and enjoy the sweet simplicity of this delicious dish! Keto rhubarb muffins can be enjoyed on a keto diet and are easy to make. Win!

🥣 How to store

If not all the muffins are eaten right away, it’s best to keep them in the refrigerator or freezer. They’re also great to keep in the freezer and pull out one a day for a quick breakfast on the go.

They will keep in an airtight container or zipper bag for up to a week in the fridge. Or, they’ll be good for about a month in the freezer, which as I mentioned is a super-convenient way to meal prep!

You can let the muffin sit out a while to thaw, or if you’re in a hurry use the microwave. I usually warm it 30 seconds on high upside down, then flip it and warm for another 30 seconds.

I was really disappointed. I've cooked pastries professionally, and these muffins turned out crazy dense, like hockey pucks. There seemed to be a lack of liquid and I felt it was a waste of good rhubarb.


Saturday 21st of October 2023

I'm sorry they didn't turn out as you wished! I love this recipe and have never had trouble with it before nor have the others who have tried it. Perhaps it was due to different ingredients or altitude.


Sunday 9th of July 2023

I find it confusing that you say 4 oz. of cream cheese when all the other measurements are volume measurements. So do you mean we should weight 4 ounces of cream cheese or do you mean 1/2 cup of cream cheese? There's a huge difference. It would help if you could answer. I'm from Canada. Our packages are 250 grams which is equal to 8.8 ounces. Thank you!


Monday 10th of July 2023

@Lauren, thank you! I tried the muffins. Yummy.


Sunday 9th of July 2023

Sorry for the confusion! Here in Colorado our packages of cream cheese are generally 8 oz each and marked on the package by the ounce. I use half a package (or 4 oz) which is also half a cup of cream cheese.


Thursday 29th of June 2023

What sweetener did you use? They can all be so different…some too sweet, some aftertaste… suggestions?


Thursday 29th of June 2023

I generally use Swerve (erythritol), but some people don't like that it has a little bit of a different taste and cooling effect. You can also use allulose that tends to taste like regular sugar but slightly less sweet.


Monday 17th of April 2023

Very delicious for being Keto. Had very nice flavor and wasn't dry. Thanks for sharing.


Tuesday 18th of April 2023

Glad you enjoyed them! Our rhubarb outside should be ready soon, and I'm looking forward to them too!


Monday 14th of November 2022

Could thus also be made into a cake?


Monday 14th of November 2022

I have not tried it that way so I cannot say for sure!
