Strawberry Rhubarb Crumb Bars (Low Carb and Gluten-Free)

You may or may not recall that I am a member of something called the Secret Recipe Club. It’s been a few months since I participated. December was simply too busy, so I skipped that month. And then the whole club took a break for January while some changes were enacted. See, the Secret Recipe Club is pretty darn huge, and the administration duties for its founder, Amanda, have been enormous. She and her group of volunteers have done an admirable job keeping the club going. I don’t think she ever realized how popular her little brainchild would be, but there are hundreds of members now. Talk about a blogger success story!

This month, I was assigned a blog that I have actually heard of before, although I don’t often read. Meet The Swans is a blog run by husband and wife team Krista and Brett, and it contains a great deal more than food. They post about everything from their home remodeling project to ideas for weddings. Fortunately, the blog also contains plenty of great recipes and I had no trouble finding inspiration. The minute I saw a recipe for Strawberry Rhubarb Crumb Bars that Krista adapted from Better Homes and Gardens, I knew I had to recreate. I adore rhubarb and have had some in my freezer that I’ve been hoarding since last June so that I could bring a little taste of summer into our lives in the middle of winter. This seemed like the perfect opportunity.

I really should be calling these Rhubarb Strawberry Crumb Bars, as they contain much more rhubarb than strawberry, but that doesn’t quite roll of the tongue as easily. Like Krista, I upped the amount of rhubarb because I love the flavour and tartness, and kept the strawberries to a minimum. I did add a little arrowroot starch to the filling to help thicken it, as the absence of sugar means it doesn’t thicken up as much as the original recipe. Of course, I couldn’t make my version with flour and oatmeal, so I created a crumb-like crust with almond flour and erythritol. I did add a touch of ground ginger to the filling, as in the original BHG recipe, but again like Krista, I skipped the ginger icing because I just didn’t think the bars would need it.

The Results: It really is nice to bring the flavours of summer into a dull, wintery day. These bars are lovely and soft and crumbly, with a not-to-sweet, strawberry rhubarb flavour. That said, I do think that next time I would make more filling, as I found the filling to crust ratio a little on the skimpy side. But I am a rhubarb fanatic and I always want my rhubarb desserts to have an intense rhubarb flavour. On the whole, I think these bars are an excellent treat.

Strawberry Rhubarb Crumb Bars

2 cups sliced rhubarb
1 cup strawberries, chopped
1/4 cup water, plus 2 tsp
1/4 cup granulated erythritol
1/2 tsp ginger
10 drops stevia extract
1 tsp arrowroot or corn starch

Crust and Topping:
2 cups almond flour
1/3 cup granulated erythritol
1/2 tsp xanthan gum
1/2 tsp salt
1/2 cup butter, chilled and cut into chunks
20 drops stevia extract

For the filling, combine rhubarb, strawberries, 1/4 cup water, erythritol and ginger in a medium saucepan over medium heat. Cook, stirring frequently, until mixture bubbles and fruit is soft enough to be mashed with a spoon. Remove from heat and stir in stevia extract.

In a small bowl or cup, dissolve arrowroot starch in remaining 2 tsp of water. Add to hot filling and stir to combine. Let sit to thicken up.

For the crust, preheat oven to 350 and grease an 8×8 inch pan.

In a large bowl, combine almond flour, erythritol, xanthan gum and salt. Add butter and stevia extract and cut in with a pastry cutter until mixture resembles coarse crumbs. Press half of mixture into bottom of prepared pan and bake 12 to 14 minutes, or until edges are just golden brown.

Spread filling over bottom crust and sprinkle with remaining almond flour mixture. Bake 20 minutes, or until topping is golden and filling is bubbly. Cool in pan.

  1. I'd like a dress in the pink color of these bars! So pretty. Your conversion of these to gluten-free is worthy of a standing ovation. There's lots of chemistry and know-how going on in your kitchen.

  2. I have yet to try rhubarb but I've no doubt that your bars were scrumptious.

  3. Really pretty treats! And definitely add a little summer to the kitchen.

  4. I have rhubarb in my freezer too and I love that I could make these for my allergy plagued daughter by just changing out the butter. I am saving this recipe in my need to make file.

    If you haven't already, I'd love for you to check out my SRC entry: Crunchy Fudgy Heart Bites

  31. these bars have ther loveliest shade … great job converting the recipe!

  32. Ah, those do look delicious. I didn't realize that it was the sugar that thickened things up, but figured the cornstarch or whatever that was added would do it. Arrowroot sounds like a nice natural way though.

  43. teaandscones says:

  44. I adore rhubarb and wish I froze some this summer. Love these yummy bars and could eat one now for dessert;)

  46. I love the idea behind the SRC. I am so happy you participate. Each month I seem to find new blogs from the postings. This looks like a delicious recipe. My husband would love it.

  47. These do look great, I will have to get some rhubarb as i live where almost all of the worlds rhubarb is grown!

  48. Thank you for this recipe :D Its amazing! Tho i did tweek it slighty.

    I ran out of sweetener so i put sugar free blackcurrant jelly powder in the fruit. Came out amazing when cooled. The gelatin kept the fruit firm and lovely :) Also used a cake tin and cut into 8 triangles as i didn’t have a 8×8 pan lol.

    Thank you

  1. […] rhubarb in my garden is doing beautifully. I made these bars with minor changes: xylitol instead of erythritol and 1/4 tsp xantham gum instead of arrowroot […]
