These soft gluten free rhubarb muffins are made with almond flour, easy to make in less than 40 minutes! No mixer needed, just a bowl and whisk. Rhubarb is folded into the batter, providing each bite with sweet, tart flavor that is complimented by coconut sugar.
I’ve loved rhubarb since the first bite of my Mom’s tangy meringue dessert, with shortbread crust and custard filling. I can picture the rhubarb patch that lined the single car garage of my childhood home. I can smell its earthiness. I can hear her telling me to go and pick 10 stalks for the rhubarb cake she was getting ready to bake.
When we looked at our now home in Wisconsin, and I saw that it had a flourishing rhubarb patch right outside the tiny shed in the backyard, I took it as another sign the home was meant for us.
I have been making these soft and tender Rhubarb Almond Flour Muffins on repeat lately. It’s an easy recipe, no mixer required, and just 25 minutes in the oven to come to life, similar to my Moist Gluten-Free Blueberry Muffins! The rhubarb pairs up with two of my favorite natural sweeteners, coconut sugar and maple syrup, to bring it to its most flavorful height.
Rhubarb is both mixed into the batter, and arranged in a pattern on top, with a sprinkle of crushed almonds for crunch. As the muffins bake, the rhubarb turns soft and sweeter. I absolutely love them, any time of day.
A combination of almond flour and oat Flour is what I use for the best texture
This recipe is inspired by and adapted from my friend Sarah’s Poppyseed Peach Muffins, who had the idea to use almond flour and oat flour to create the perfect texture in a muffin. Together they keep the muffins moist, yet give it structure.
I also let the batter sit while the oven is preheating, rather than baking them right away after mixing. This allows the flour to absorb all the liquid ingredients so they can rise tall.
Deliciously Moist Gluten-Free Rhubarb Muffins
These soft and tender gluten-free rhubarb muffins are made with almond flour and are a breakfast or snack delight! Naturally sweetened with coconut sugar, these muffins are healthy and delicious.
110gramschopped rhubarb + 1 extra stalk for making the decoration on top
1/4cupfinely chopped raw almonds or pistachios
Instructions
Prepare a 12 cup muffin tin with liners.
Mix almond flour, oat flour, coconut sugar, baking powder, baking soda, and salt in a large bowl.
In separate bowl, whisk together eggs, maple syrup, milk, almond oil, vanilla.
Add wet ingredients to dry ingredients, and stir to combine – a few streaks of flour are okay. Then fold in rhubarb, which will also finish combining so no dry flour remains.
Preheat oven to 375 degrees F. Let batter sit while oven is preheating. This allows the flours to absorb the liquid ingredients. When oven has preheated, use a cookie scoop to add batter, almost near the top, of each liner. Top each muffin with three or four small pieces or rhubarb. Sprinkle with crushed almonds.
Put muffins in the oven and turn heat down to 350 degrees F. Bake for 22-23 minutes, until toothpick comes out clean. Let cool on a wire rack.
Place muffins in a covered container or kitchen bag, and cover them with a paper towel sheet. Then store in refrigerator. The paper towel absorbs the moisture that muffins give off, which keeps them from getting soggy and a weird film on top.
Can I freeze rhubarb muffins?
Yes, in fact I suggest it if you aren’t going to eat all of the muffins within two days. They freeze extremely well, and stay at their best that way!
Can I halve this recipe?
Yes! I’ve halved this recipe successfully, and it will make 6 muffins. Perfect if you are a house of one or two.

I made these muffins but discovered afterwards that the oat flour was organic but not specifically gluten free. Can I substitute coconut flour for the oat flour? The muffins were easy to make and moist.
Hello! Which brand of oat flour did you use? Unfortunately coconut flour cannot be substituted because it absorbs a lot more liquid, so the muffins would turn out extremely dry and dense.
Hello Rick! Although I have not tested replacing the almond flour for this specific recipe, typically the best substitutes for almond flour are oat flour or Bob’s Red Mill GF All purpose 1-1 Flour in the blue bag if you wanted to try. I can’t guarantee though, as I have not tested.
Hi Andrea! Yes, I like to refrigerate them when I go to bed for the day. You can put in microwave for 10 minutes to re-warm. And they freeze extremely well!
I rarely bake with rhubarb but I picked some up at the store on a whim today and made these muffins. Whoa! So delicious and great texture. I subbed olive oil and almond milk and it worked out great.
This turned out to be so delicious and very easy and quick to make. Thank you so much :). Planning on trying the recipe with different fruits depending on what’s in season.
These muffins are delicious! I used olive oil as I don’t have any almond oil and it works well! I made them vegan with chia ‘egg’ and my whole family love them! Will definitely make them again!
Thanks! I’ve used both sunflower and safflower with great results! I do have another question. These muffins puff up nicely for me in the oven, and then as they’re cooling, they always sink in in the middle. Any tips on how to prevent them from turning into little sink-holes? The only other ingredient I usually have to swap out (besides the oil) is coconut sugar for cane sugar, since my stomach can’t handle coconut products. I appreciate your help and love these muffins oh so much.

Hi, my partner is both celiac and allergic to almonds. Is there a different flour that works in this recipe?
Thank you!

Hi, wondering if I can change out the Oat flour for Coconut flour ?

Hi! Coconut flour absorbs an extreme amount of moisture so can not be used in this recipe as it is written.

I’m flirting with a bunch of locally farmed rhubarb and want these for breakfast tomorrow! Would coconut oil and coconut milk work instead?
Amanda Paa

Yes, that should work just fine!
Make sure you measure the coconut oil melted to match the oil in the recipe, not in a solid state.

They turned out amazing. My husband LOVES them. The only thing I’m still curious about is the breakdown of nutrition information.

If I do not have almond oil, can I substitute any oil commonly used in baking? I understand the flavor would come out a little different. Thanks!
