A delicious and easy vegan Rhubarb Mousse -- the perfect dessert for a lazy spring or summer afternoon. The mousse is sweetened with maple syrup and fruit juice and has hints of vanilla and cinnamon.

Every year, when Spring rolls around, I cannot wait to get my hands on some rhubarb.
Rhubarb apparently grows wild in the mid-west, but here in my part of the United States its popularity makes it a hard stalk to come by. This year, I started looking for rhubarb in just about every supermarket and farmer's market in my neighborhood weeks ago, but everywhere I went I'd be met with empty baskets and apologies. I got so tired of hearing, "Sorry, we're out of it," that I started to resign myself to the idea of a rhubarb-less Spring. And then, lo and behold, I was at this little grocery store not one block from our home and there, right in front of me, was a big basket of juicy, colorful rhubarb stalks.

I squealed with delight and picked one, and a friend from China who happened to be staying with us looked at me, puzzled, and asked, "celery?" She couldn't quite understand why I was so excited.
Truth is, there is just something magical about these ruby-red stalks. Rhubarb is incredibly tart-- so much so that it is hard to imagine its popularity as a dessert ingredient, if you've never had it. And if you never have, well, there's only one way to remedy that.

One of my favorite ways to eat rhubarb is in a Rhubarb Pie, but this time I wanted to make something cool and refreshing and delicious that would be perfect to gorge on during a lazy weekend afternoon. Like this Rhubarb Mousse.
I wanted to make this mousse soy-free, so instead of tofu, which I might have normally added, I chose coconut milk. This is the kind of coconut milk that comes out of a can, and you want to use just the thickest part. Also make sure your coconut milk is fresh and sweet-- this is one ingredient that loves to go rancid on you when you leave the can someplace hot.
To add more flavor to my Rhubarb Mousse, I threw in the seeds of a vanilla bean, some cinnamon, and some delicious, deep, rich maple syrup. Perfect.
Try making this beautiful mousse if you have some time this weekend. It doesn't take long at all, I promise.

Diana
Hi! This sounds wonderful, but I can't have coconut milk. Would almond milk or another plant milk work?
Vaishali Honawar
Hi Diana, yes, either would be fine!
Kate
Hey, this recipe looks great, and just what I was looking for! How does it keep in the fridge, and for how long? 🙂
Vaishali
Hi Kate, you could keep it refrigerated about two to three days. Cheers.

Perfect1 You just solved y how-to-use-all-out omegrown-rhubarb dilemma, thanks 🙂 I have all the ingredients to hand...
Vaishali
Great! I hope you will try this. Lucky you with the homegrown rhubarb! 🙂
Karen
Looks beautiful, though I'm not sure I like the idea of coconut and rhubarb flavours together. Does the coconut taste come through?
Vaishali
Hi Karen, yes, you can taste the coconut and I really liked the flavors together, although I guess it's a matter of taste.
Ellen Lederman
Vaishali, I have serious rhubarb envy! I missed the short window of opportunity that rhubarb is available here in Atlanta, so this recipe will need to wait until next year. Sadly, I've only tried rhubarb once. A vegan blog I follow had a recipe for tofu in a rhubarb sweet and sour sauce. I was a little dubious about it but loved it.
Vaishali
Hi Ellen, that sweet and sour rhubarb dish sounds delicious. Next year, I think I'm going to try growing some rhubarb-- I was looking for it again yesterday and couldn't find it anywhere. If it grows as easily as it's supposed to, I will just take the easy way out. 🙂

Hi V. Thanks for the recipe! So excited to try this one. I have a big patch of rhubarb growing in my back yard, and I never really give it a second thought. (don't hate me cuz I'm beautiful..lol). Now I can march on out there and hack some down and make this yummy looking moose (sic cuz I'm Canadian and moose are abundant.) Have a nice weekend.
Vaishali
Hi Mary, I am so jealous of that rhubarb patch! 🙂 And I hope you try this animal-free moose. 🙂 I polished off the last bit yesterday and miss it already.

Ooo I've only ever made pie with rhubarb. I didn't grow up with it so I had the same reaction as your friend when I first encountered it! lol I really want to give your recipe a try so I'll hunt down down rhubarb!
Vaishali
Hi Mary, yes, it does look so much like celery, doesn't it-- like the prettier, flashier twin? 🙂 Hope you will try.
