Oatmeal cookie base topped with sweet and tangy rhubarb and strawberries covered in more oatmeal cookie topping — your favourite summer dessert is now a portable treat or back to school snack!

I once asked this question over on my Facebook page: fruit crisp or fruit pie?

At first, I was a little alarmed at the amount of pie people popping up and taking over. But once I sent a shout out to all my crisp lovers they slowly came through for me.

I am a crisp lover. I am not reeeeally 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 last summer, when Julianne from Beyond Frosting asked if I would bring something over to share, these bars were not 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.

I’ve since updated the post so that you can find the full recipe below, because Spring is short and you should be eating as much strawberry rhubarb as you can get your hands on.

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? Total obsession.

Especially strawberry rhubarb. And with fresh summer 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!

  • 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 1/2” pieces
  • 4 cups fresh diced strawberries
  • 3 cups frozen chopped rhubarb (or sub fresh – see recipe notes*)
  • 1/4 cup corn starch
  • 3/4 cup granulated sugar


  • Preheat the oven to 350 degrees F and line a 9×13” pan with parchment paper. Set aside.
  • 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.
  • 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 10-15 minutes until dry on top.
  • In a medium bowl, 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.
  • Bake for 40-45 minutes until the filling is bubbly and thickened and the oats are light golden brown.
  • Cool to room temperature. I highly recommend chilling before cutting – they will set completely and cut more cleanly. Store in the refrigerator


I only had frozen rhubarb available. You can easily substitute fresh but it won’t release as much liquid as it bakes, so you’ll need to reduce the corn starch to about 3 tablespoons.

      Sorry Sue! When I switched over to me new recipe box something funny happened and earlier versions are displayed below.. Always go by the recipe in the box — I will go in and delete the previous one!

    Amazing recipe!! I veganized it with vegan margarine. No tin foil, just greased a pyrex baking pan. I used fresh rhubarb and 1 T cornstarch and the texture and taste was spot on. Definitely heed the advice to cool/chill before cutting!

  2. Kane says

    I made these yesterday and was pretty bummed. The taste was fantastic but I could not get them off the tinfoil. And I had made sure to grease the foil pretty generously. Unfortunately, the bars weren’t presentable once I got them separated from the foil. Perhaps they would work great without the tinfoil but I’m not sure I’m willing to try again. They were also more mushy than I would have liked for a bar. Flavor was excellent though!

    • Ashley Fehr says

      Oh I’m sorry to hear that! I’ve never had any trouble with these bars coming out. Maybe you could try parchment paper next time? I think it’s even a little better than foil for being non stick.

  3. Teresa says

    Hi ! I made these last night to bring to my office. After giving my husband a taste last night, I had a terrible time keeping him away from them. My co-workers finished them off in minutes. They were perfect and are my go to recipe now. Thank you.

    I am a total crisp lover too! I’m not a big pie unless is a dutch apple pie, then I can eat enough for you and I both. 🙂 So I have a confession to make. I’ve never eaten rhubarb. Can you believe it? These bars look incredible and I need to make them before rhubarb is gone for the season. Pinned!

  5. Dorothy Dunton says

    Hi Stacey! I have always loved rhubarb! I have a recipe for a crisp that my husband’s secretary gave me years ago. Unfortunately, rhubarb is one of the things that won’t grow here – we’ve tried, but the soil (or more aptly described “clay”) just kills it off! I have a good friend back in MI who used to bring me rhubarb every summer so I would make me pie – his wife didn’t bake. Now I’m on a quest to find some thanks to you! 🙂 Actually we are going to Knoxville tomorrow (furniture shopping) and I know of a food co-op that just might have some!

    • Ashley Fehr says

      Yes I’m really glad we can grow it here! We just planted our own bushes this Spring but we won’t get enough from them this year to make anything. Hopefully next year!
