Keto Rhubarb Dream Bars are a layered dessert bar made of a shortbread crust, a layer of rhubarb custard, and creamy topping! This recipe came about because of my complete and total love of rhubarb and my desire to have a low carb, keto version of one of my favorite desserts!
I have made a rhubarb custard bar for years now. So when my rhubarb came in, my mind naturally went to that recipe and how much I wanted to eat it. However, even though my mind wanted it, my body knew it needed a keto version.
These rhubarb bars were very easy to make keto. I made the shortbread crust with almond flour, coconut flour, and replaced the sugar with swerve.
I am ecstatic with the fact that I have rhubarb growing at home now. It is probably one of my favorite spring treats (next to asparagus). I think my next recipe is going to be a barbecue sauce made with some of said rhubarb!
When I made the custard, I added an extra egg and sprinkled a little xanthan gum lightly over the mixture to help thicken it some. It worked out perfectly!
The 9×13 pan worked perfectly and the custard filled out the 2nd layer without being too full. I did find that I had to bake this a little longer than the non-keto version of this recipe. However, as you can see below, they turned out wonderfully!
After removing from the oven, the rhubarb bars will need to cool. Once they are completely cooled, you can make your cream topping, spread over top of bars and garnish with fresh slices of strawberries!

I keep saying that I need to make more rhubarb recipes – and this one sounds delish! Love that it’s keto friendly as well.
Sally - My Custard Pie says
You know I’m going to hunger after anything with custard don’t you?! This is a really original way of combining two favourites.
Laura says
I never had rhubarb bars and this sounds like a perfect recipe. I love rhubarb and de
Marie says
These bars are a dream! Delicious layers and perfect to make this time of year while rhubarb is in season! Pinning this recipe!
Hannah says
I made this today but without the whipped topping. I don’t think the crust measurements are correct for a 9×13 pan. I ended up making another 1/2 recipe of the crust but it could have easily been doubled to look like the thickness of the crust in the photos. Also, the crust instructions say to add salt but there is no salt listed in the ingredient list. Overall the flavor and texture of the bars is good.
Shelby says
Hi Hannah, thank you for your comment and review! I will fix that salt issue ASAP! Also, I think the crust layer looks thicker on the cut slices because the custard baked into it more than it would have a conventional flour crust. My actual crust layer was pretty thin (as it should be). I’m glad that overall you enjoyed this recipe!
Suzanne says
This recipe looks wonderful! Thanks for sharing it. I can’t eat Cool Whip. Do you think I could substitute heavy whipped cream for the Cool Whip?
Shelby says
Hi Suzanne, thank you 🙂 Yes, I do think you could sub heavy whipped cream for this. I would be sure my cream cheese is nice and soft before I stirred it in. In all reality, it would probably be a better flavor profile than cool-whip!! I may have to do this myself next time I make this recipe. 🙂
Ashley says
Watch the cooking time on the crust. Glad I checked.. it was golden brown at 12/13 minutes. Also, directions for tipping says to mix swerve in, but it’s not listed in the ingredients??
Shelby says
Hi Ashley, thank you for mentioning this! It did get fixed….there is swerve in the topping.
Traci says
Wow! These look amazing! I definitely don’t play with rhubarb enough…this is a great way to do it! Thanks for sharing 🙂
Joell says
I am making these today! So excited to try them. I am at the topping part, and the instructions say to cream together the cr cheese vanilla and swerve but there is no measurement for that ingredient?
Shelby says
Hi Joell, so sorry I didn’t see this before now. We are in major kitchen renovation and I haven’t had a chance to log in. Yes, there is swerve in the topping, the ingredient was omitted by error when updating the recipe card.
Roger says
Swerve is not listed in the cream topping but it is included in the preparation. is that just a typo or is swerve included in the topping?
Shelby says
Hi Roger, so sorry! When I changed recipe cards that ingredient was inadvertently omitted. I have updated the recipe now – there is swerve in the topping also.
