Impossible pie? With Saskatoons? Let sit and talk about how this is a REAL THING! Yes, this pie is crustless and bakes up in layers – with Saskatoon berries, blueberries, the sky is the limit! This is a riff on the classic impossible coconut pie.

The Classic Impossible Pie Recipe

If you are expecting a crispy pie crust you need to turn away now, for this is not the recipe for you. Go and make my Saskatoon Rhubarb pie instead, if you need a neat pie idea to use up those Saskatoon berries and another summertime bounty. It’s one of my favorites.

*waves hand in front of your face*   This is not the pie crust you are looking for.

All bad Star Wars references aside, anyone who has eaten Impossible Pie before knows that it’s not really about the crust, but the fact that you beat together a schwack of ingredients in one bowl and pour them into a buttered pie plate. The flour will sink to the bottom and form a wobbly flour crust, while the rest creates a custard filling and a topping.

I can’t believe that I just used the word schwack in a recipe. This pie is a last-minute, want-to-use-up-Saskatoons-but-don’t-want-to-make-a-crust type of dessert.

This delicious pie was on the docket for my cookbook, but didn’t make my vicious cutting. I decided that this one was for the website, meaning that technically you guys get a cookbook recipes a year ahead of time! Right? Right. (that’s how I’m going to sell it to you anyway.)

The scene: my house on an August long weekend. My entire family was over, I’d already baked two pies for dinner (those are embargoed cookbook pies, sorry) and I was looking through old cookbooks looking for a great porcupine meatballs recipe, something else that has been on my mind lately but of course, I haven’t gotten around to it. You all have been so patient, this website has been a little slow lately, but I’m rather proud that I have managed to get out at least one post a week and usually two, which you might think isn’t much but when you have a cookbook manuscript due, it’s a miracle. A full-out, Catholic church confirmed miracle.

I’ve had a recipe for Impossible Pie kicking around for a while and while it is delicious with its custard filling and crispy coconut topping, I wanted to jazz it up.

Karlynn’s Tips & Tricks for Amazing Impossible Pie

  1. Two cups of Saskatoon berries does the trick, my friends. That’s a whole lotta jazzing up right there. You can also use blueberries if you’re fresh out of Saskatoons, but this pie is now a last-minute favorite for when I am craving Saskatoons but don’t have the time for a pie with a crust.
  2. The crust is not crispy and it’s not supposed to be!
  3. I would say that the impossible crust resembles a firm custard that’s been cooked up, it’s wobbly, not firm but does the trick. I love the eggy custard that forms in the middle it’s absolutely scrumptious. The coconut and the Saskatoons bake up at the top and it’s a taste combination that I am having a serious love affair with. There will be another Saskatoon and coconut mash-up recipe on this website soon, you can bet on it. Honestly, what doesn’t Saskatoons go with? I’ve yet to find it.
  4. This pie is going to rise “edges first”,  but the center will soon catch up with it, don’t worry! It will look absolutely wonky to start, but by the time the 50-60 minutes are done, it will be fabulous!

So now that my manuscript is into my publishers hands, things are going to pick up around here again.

I’m baaaack!

(not that I ever really left but it just feels like the right thing to say.)

Love you more than chocolate,


* note – to use frozen Saskatoons, thaw them on a paper towel to absorb any excess moisture, then dab them slightly. The cornstarch in the pie helps with any extra moisture. This pie was made with frozen Saskatoons! *

    Has anyone tried this WITHOUT COCONUT? If so, did you substitute anything? If not, did you add more berries or change the recipe in any other way? Would appreciate any suggestions!

    • Kelley says

      I’m wondering this too….Did you try without coconut? Would be nice if someone answered…

      • Karlynn says

        You can try it with slivered nuts or even oatmeal to replace the do have to have something with volume however to keep this together.5 stars

  2. Seema says

    is it really supposed to have 2 cups of milk? This is making a very very runny liquid.

      Have you tried making this recipe with gluten free flour? If so does it have the same results as regular flour?

  5. Stacey Woodward says

    This is the deliciousest! Love this recipe, thank you

  6. Lb says

    Do you serve right out of the oven or wait for it to cool?

  7. Tara Yorz-Brown says

    This recipe looks delicious. I really want to try and make this, but I don’t know, much about blueberries, do I have to get this specific kind of blueberry or will any do? Or is the Saskatoon the blueberry I see in the store? Also, I have never made a pie before, since you just mix everything together, is this recipe good for beginners? Any help is greatly appreciated. Thank you

    • The Kitchen Magpie says

      Any blueberries and yes this is a beginner pie. No pastry crust, follow the recipe instructions!

    • Tara Yorz-Brown says

      Awesome! Thank you. I’m very excited to try this, so is my husband. Fingers crossed!!

  8. Patricia Aackerlund says

    Anything blueberry I love PLUS they are so healthy!

    • Terry Reban says

      I have made this several times and LOVE it. I hardly ever made pie because I don’t care for pie pastry but my family is so this is a win win! I cut back the butter just a hair because it runs over my pie plate. Tonight I am trying a different plate and have mixed in rhubarb with my saskatoons!5 stars

  9. Laura Delorme says

    This will be a perfect dessert and a delicious way to use some of the saskatoons I have in my freezer. Thank you!

  10. Natalie Tremblay says

    I saw in the on-line comment that you can substitute the Saskatoons for blueberries. What about using gluten-free flour instead of normal flour… do you think it would come out OK?

    • The Kitchen Magpie says

      That I haven’t tried…I’m not sure.

    • Natalie Tremblay says

      ok thanks. i get it… why bake GF when you don’t have too. I don’t blame you 🙂 Might give it a try. Will let you know if I do.

    • The Kitchen Magpie says

      I do have a flour mix, it’s very expensive to fool around with though. Also my one gluten free family member is also I don’t bake for her much at all, double difficulty!

  11. Patricia Kennedy Crnogorac says

    Is this in your cookbook? I preordered it.

    • The Kitchen Magpie says

      No, it’s not. I tried for as many new as possible! Maybe next cookbook? \U0001f609

  12. Wilma Plishka says

    I made this a few weeks ago for a potluck. It definitely was a favourite!

    • Wilma Plishka says

      The Kitchen Magpie I told everyone about you! Love your recipes.:)

  13. Jackie Burke-Lorette says

    Goodness this looks so good.A must try.No Saskatoon berries will try blueberries.

    • Karen Cicansky says

      Mix some of the sugar with the blueberries and add a tsp of almond flavouring. This mimics the Saskatoon taste!

    • Jackie Burke-Lorette says

      Thank you for the hint about the berry mix.
