These vegan strawberry rhubarb crumble bars are a perfect way to celebrate strawberry season! They feature a soft cookie layer, a quick, sweet strawberries and rhubarb, and a classic crumble topping. They also happen to be gluten-free.
Am I the only one here who’s just a little intimated by rhubarb?
I love its beautiful color, and I almost always love the foods that are made with it, including jam and pie. But this sturdy ingredient always strikes me as a little daunting.
These vegan strawberry rhubarb crumble bars were developed with my desire to get to know rhubarb a little better. As I made them, I developed a whole new appreciation of rhubarb and its tart flavor—a flavor that perfectly balances the sweetness of ripe strawberries.
Rhubarb is the edible stalk portion of a vegetable that has a leafy, non-edible top. It has a famously tart flavor. This is why rhubarb is most often included in recipes that are sweetened. It’s also part of why it pairs so well with sweet, juicy strawberries.
This recipe was inspired by my blueberry breakfast bars. They’re one of the most popular baked goods from my blog!
To make the bars, you make a dense, soft bottom layer. I use some mashed banana in the base to help replace egg. It’s an easy mixture to prepare, and you simply spread it in the bottom of a prepared baking dish.
The strawberry rhubarb layer is super easy to prepare: just a matter of mixing strawberries and chopped rhubarb with sugar and tapioca starch. The fruit layer is spread over the dense bottom layer of the bars.
Finally, you’ll prepare a traditional crumb topping and sprinkle it on top of the fruit. The crumble topping is what makes these bars as fun and delectable as they are!
The strawberry rhubarb crumble bars are gluten-free thanks to the use of oat flour. You can purchase oat flour, but you can also make it from scratch. To do this, place oats into a food processor fitted with the S blade and then whirl them until they’ve formed something resembling flour.
If you’re not gluten-free it’s also totally fine to prepare the recipe with all-purpose flour! You can use the same amount of unbleached, all-purpose flour in place of oat flour.
You can store the strawberry rhubarb crumble bars in an airtight container at room temperature for up to three days. After that, I recommend storing them in the fridge. They can be stored for about five days total.
If you’d like the bars to last longer, you can freeze them for up to six weeks! I like to freeze them individually and defrost them one by one for breakfast and treats.
These strawberry rhubarb crumble bars is that they bridge the gap between breakfast and dessert. You could enjoy them with a smear of nut butter and some fresh fruit for a sweeter breakfast or brunch.
You could also serve them with a nice dollop of sweet cashew cream for dessert. No matter how or when you decide to eat the bars, I think you’ll find them to be sweet, nutty, buttery, and satisfying.
This bar recipe would be a great template for many other fruit flavors. You can use four cups of blueberries, cherries, chopped peaches, or chopped apples. Change up the fruit filling according to the seasons and what you’re craving.
Enjoy the bars, all!

The ingredients say baking powder but the recipe says soda — which is it? Looks yummy, want to do it right!
Powder! I’ll fix the recipe—thanks for noticing this, Hannah 🙂
Crumble bars make me full faster than anything else. So nutritious and delicious, thanks for sharing the recipe. 🙂
Currently eating this… It is so good!
Hooray! So glad.
As someone who’s spent her whole life with a rhubarb plant in the front garden (and it’s the only truly edible thing ever produced in our garden- unless you count an 1/8 inch radish) I’m not scared of rhubarb. But as a graduate from Rhubarb U- I can tell you that you have totally nailed this recipe!
Yum! I don’t think I’ve ever bought fresh rhubarb before. They have a bunch of it at my local farmer’s market, so I am going to pick some up and try this recipe! 🙂
I’m impressed how you managed to mash up breakfast and dessert with your strawberry rhubarb crumble bars. I love rhubarbs and this recipe totally gets a thumb up for me
I made this recipe last night for dessert and now am eating it for breakfast this morning! It is very versatile and delicious! My mother has tons of rhubarb in her garden every year and always gives me lots to put in my freezer. I am always looking for recipes to use it in. I still had some in my freezer from last year so I pulled it out and used it for this recipe along with some frozen blueberries, raspberries, and strawberries. I’m having it with a smear of almond butter and dollop of plain coconut yogurt so it tastes breakfast-ey! Thanks for a great recipe:)
I’m intimidated by rhubarb too, but this looks lovely and delicious. Looking forward to trying it maybe for Mother’s Day brunch, thanks.
Love rhubarb season! I also made a rhubarb crumble on the weekend, the first of the year, and we also demolished it in a single evening. As a kid we had rhubarb growing in the back yard and my parents used to try and pawn it off as a dessert which we were having none of, but as an adult I so appreciate it’s tartness and the complex flavours it brings to the table. I’ll definitely be trying these bars with my next batch of rhubarb. Thanks Gena!
sounds and looks amazing!! Can’t wait to try it 🙂
Wow – what a great sounding bar! I am totally not intimidated by rhubarb at actually. I tend to keep it simple though, with things like crumbles and such. But my absolute favourite way of enjoying it is in soup. Gives it a fun, tart flavour =)
These look delicious – and it’s so great they’re vegan too! I giggled a little at you “bridging the gap between breakfast and dessert” – that’s definitely something I’d love to wake up to!

I love the strawberry rhubarb combination and I really want to try these! The last time I cooked rhubarb myself was when I was about 7 years old and one of my best friends and I nearly burned down her parents’ kitchen. We boiled rhubarb that grew in her garden (I don’t even think we washed it) and tried to combine it with cookies that we didn’t use a recipe for that melted all over their oven. Disaster. Anyway, I’ve learned a few things since then so I’m sure making these bars won’t be a problem 😉
This does look delightful – just how you described it!
I’ve always been intimidated by rhubarb too. I think I’ve used it in a recipe one time. But these look so good that I may have to try it again.
These bars look pretty amazing! I’ve never purchased rhubarb, but now I think I might have to! 🙂
I LOVE rhubarb. Up north here, it grows like crazy in my mother-in-law’s and many of my friends’ gardens and so once our rhubarb season is upon us (we’ve still got at least a month to wait!), I’ve got a seemingly endless supply of the bittersweet fruit for the summer. It’s also wonderful just gently stewed on the stove with a bit of sweetener and added to oatmeal (or ice cream!). XO
Oh, Gena. Blake is going to go bananas when I make these for him. Every spring when rhubarb is in season he requests a strawberry rhubarb pie. But, I often don’t have the time or patience to make pie. But, this looks easy to make and includes many of his favourite foods, including oats and banana. I can’t wait to make it for him!
Nope you’re definitely not the only one, rhubarb freaks me out too! I applaud you for taking it on and creating something so delicious out of it. You are encouraging me to buy some next time I see it…maybe 🙂
