I have another guest post for you guys today! Ashley from the The Recipe Rebel is sharing these gorgeous Strawberry Rhubard Crisp Bars. Ashley’s blog caught my eyes time and time again. I would be strolling through Pinterest, pinning these amazing dinner and dessert ideas and it was already leading me back to Ashely. Recently, her summer recipes are knocking my socks off. Recipes like this No-Churn Coconut Cream Pie Ice Cream or No-Bake Banana Split Cheesecake. I also find that her mouthwatering savory dishes can also be found amongst my Pinterest boards. Have you seen her BBQ and Chedder Poutine? Or how about Easy Loaded Baked Potato Quiche? I want it all! Thanks for sharing Ashley! 

I asked this question over on my Facebook page a little while ago: fruit pie or fruit crisp?

At first, I was a little surprised at the amount of pie lovers popping up and taking over. But once I sent a shout out to all my crisp lovers they slowly came trickling in.

What about you? Are you a crisp lover or a pie lover?

I am a crisp fanatic. I am not reeeally a pie lover, unless it’s filled with chocolate or peanut butter or it’s on an Oreo crust or it’s in ice cream form. Or unless it’s only dessert option, because when it comes to pie or no dessert you better believe I’m eating pie and loving it. As long as there’s ice cream.

So when Julianne asked if I would bring something over to share, these bars weren’t even a thought. I’d hate to think about what might have happened if she’d never asked — you might not have been feasting your eyes upon them right now.

And that would be sad. Because they’re amazing.

When I came up with the idea for these bars, I was determined that there would only be one crumb mixture and that would serve as the cookie crust and the crumb topping. I am not into extra work.

Obviously I had to use the oatmeal cookie topping from this Berry Cherry Crisp (also amazing). I doubled it and it worked so well! The perfect sturdy base for the fruit and just enough left over to sprinkle over the top and let that gorgeous fruit shine through.

Are you guys rhubarb lovers?

I mean, you’re here, so….

But really — there are people out there who don’t like rhubarb. I used to be one of them. As a kid, anything even a little bit tart was not dessert. Lemon, lime, rhubarb — I detested them all. Slowly, though, I came around. And now? Totally obsessed.

Especially strawberry rhubarb. And with fresh picked strawberries? Perfection!

These are the perfect bar to take you from summer right into back to school — they are incredible cold, straight from the fridge, or warm them up and serve with some vanilla ice cream!

Strawberry Rhubarb Crisp Bars

  • Author: Julianne Bayer

Ingredients

  • 1 cup packed brown sugar
  • 2 cups large oats
  • 1 cup whole wheat flour (or sub all-purpose)
  • 3/4 cup cold butter, cut into ½” pieces
  • 4 cups fresh, diced strawberries
  • 3 cups frozen, chopped rhubarb (or sub fresh – see recipe notes*)
  • 1/4 cup corn starch
  • ¾ cup granulated sugar

Instructions

  1. Preheat the oven to 350 degrees F and line a 9×13” pan with tin foil or parchment paper, lightly greased. Set aside.
  2. In a large bowl, combine brown sugar, oats and flour until mixed. Add the butter and mix with an electric mixer, a pastry cutter or your hands until combined (dough will have the consistency of cookie dough – it won’t be crumbly).
  3. Set aside 1 packed cup of the oatmeal cookie mixture. Press the rest into the bottom of the prepared pan, covering the bottom entirely. Bake bottom crust for 10-20 minutes, until dry and golden.
  4. In the same bowl you used to mix your oats, combine your strawberries, rhubarb, corn starch and sugar. Spread on top of crust and crumble the remaining oat mixture on top – it will not cover the top completely. Press down the oat mixture slightly.
  5. Bake for 45-50 minutes, until filling is thickened and bubbling and crumble is golden.
  6. Cool to room temperature. I highly recommend chilling before cutting – they will set completely and cut more cleanly. Store in the refrigerator.

Notes

I only had frozen rhubarb available. You can easily substitute fresh but it won’t release as much liquid as it bakes, so you maybe need to reduce the cornstarch.

    I agree with Judi- I made these yesterday and was pretty bummed. The taste was great but I could not get them off the dumb tinfoil! They were not presentable once I got them separated from the foil. And I greased the tin foil plenty too. Perhaps they would work great without the tinfoil and I’d be willing to try them without sometime. I also agree with Judi that the recipe was more of a crisp than a bar- pretty mushy. Recipe needs some tweaking.

      Hi there, and thank you for letting me know. I’ve contacted Ashley, who shared this recipe on my site and I am asking her for some advice. I might recommend using parchment paper instead of tinfoil

      1. Beyond Frosting

        Hi Spring, I just wanted to thank you for your feedback and let you know that the recipe has been updated. Ashley re-made these and made the necessary adjustments

  2. Judi

    I made these delicious looking bars today. Unfortunately they did’t turn out as good as your bars did. They tasted good–once we peeled off all the little pieces of aluminum foil. I will try these again without the foil though. The recipe was easy to make but cook time seemed quite a bit longer to get the oatmeal mixture to brown. Even after about 35 minutes, the bars are still more like a crisp. Still tastes good–just didn’t set up quite right.

    1. Beyond Frosting

      Hi Judy, thanks for sharing your feedback. This was a recipe contributed to my site, but I will defiantly ask her if she has any suggestions. You thing you might try is using parchment paper instead of foil.

    These bars just look like summer to me! I love strawberry and rhubarb together – so perfect in these bars!

    My goodness, I love everything about these bars! They are bursting with strawberry flavor. Thanks for sharing, Julianne and Ashley!
