Looking to feed a crowd for a summer picnic?  This Blueberry Slab Pie with Sugar Cookie Crust is a tasty answer!As much as I love a good pie dish, sometimes I’m just not in the mood to roll the dough out and fit it neatly into that pie dish.  Sometimes I just want to press it into a sheet pan and call it a day.  That’s what happens when you make this Blueberry Slab Pie.  Sure, you still have to roll the pie dough out a bit, but it’s much more forgiving when all you have to do is shove it into a sheet pan!

Looking to feed a crowd for a summer picnic?  This Blueberry Slab Pie with Sugar Cookie Crust is a tasty answer!I have no idea who invented the concept of slab pies, but I do know that person should be given an award.  Slab pies are baked in a standard rimmed sheet pan.  That means they’re not only easy to make, but easy to clean up as well.  Slab pies are also perfect for a crowd.  This Blueberry Slab Pie with Sugar Cookie Crust yielded 20-24 large pieces.  Imagine cutting a standard pie into that many slices.  After two bites, you’d be in the kitchen looking for the rest of your slice of pie!

So we’ve established that slab pies are easy.  And we’ve also established that slab pies feed a crowd.  Now let’s talk about another bonus of slab pies.  They’re crust focused.  As in the crust-to-filling ration is a bit higher than what you find with most pies.  And we all know that the crust is one of the best parts of the pie, right?

Speaking of crust, I used a standard pie dough (double batch) for the bottom crust of this Blueberry Slab Pie.  However, I took a detour when it came to the top crust.  Instead of more pie dough, I made a batch of classic sugar cookie dough.  Then I just dropped misshapen blobs of sugar cookie dough all over the top of the blueberry filling.  It turned out quite well, don’t ya think?  From the crispy sugar cookies on top to the blueberry filling that’s bursting with flavor, I truly can’t pick my favorite part of this pie!  I just want all the pie.  Every last bit of it.

Speaking of the blueberry filling, this one couldn’t be easier to make.  No need to pre-cook the filling or anything crazy.  Just grab several cups of blueberries (fresh or frozen) and mix ’em with some sugar and cornstarch.  Oh, and a bit of lemon juice helps balance the sweetness from the berries.  (Lemon juice is a secret ingredient whenever baking with sweeter berries.)  Spread the blueberry mixture on top of the pie dough, and you are 2/3 of the way to slab pie nirvana!

For the Dough

For the Sugar Cookie Topping

For the Filling


For the Dough

  • Using a food processor, add flour, brown sugar and salt; pulse until well combined.
  • Cut butter into small cubes and add to the food processor; pulse until a crumbly mixture forms.
  • Add ½ cup of water and pulse until well combined. Continue adding water 1 Tbsp at a time (and pulsing) until dough comes together in a ball.
  • Flatten dough into a disc and wrap with plastic wrap. Refrigerate for at least 2 hours. (Note: Dough can be made the day before and refrigerated overnight.)

For the Sugar Cookie Topping

  • Using a medium mixing bowl, cream together butter and sugar until light and fluffy (~2-3 minutes on medium speed).
  • Add egg and vanilla; mix on low speed until just combined.
  • Using a separate bowl, sift together flour, baking soda and baking powder. Add dry ingredients to the mixing bowl and mix on low speed until just combined. Set bowl aside.

For the Filling

  • Preheat oven to 375°F.
  • Working on a lightly floured surface, roll dough into a 12”x17” rectangle. Press dough into a 10”x15” baking pan. (Note: Take extra care to press dough into corners of the pan.)
  • Using a large bowl, add granulated sugar, brown sugar, cornstarch and lemon juice; stir until well combined. Add blueberries; stir until well coated. (Note: The filling will not completely cover the dough. As the pie bakes, the berries will burst and fill in the gaps.)
  • Using a slotted spoon, transfer blueberry mixture into prepared pan.
  • Drop pieces of sugar cookie dough evenly on top of the filling. Sprinkle top of pie generously with coarse sugar.
  • Bake for 43-45 minutes, or until sugar cookie crust is golden brown.
  • Let cool for 1 hour before slicing and serving with {optional} vanilla ice cream.

    Love this blueberry slab pie, David! It makes more sense than a traditional pie when you have a group of people who want dessert. So convenient, delicious, and I love that it’s so easy to serve.

    1. You’ve got that right, Marissa! If you need a dessert for a crowd, then a slab pie is the way to go. It’s SO easy to make, too. 🙂

  2. 5 stars
    Now that’s a pie! I love that you used sugar cookie dough for the top crust. That is a fabulous idea! I’ll have to be certain I have a large enough crowd to serve when I make this pie, otherwise I’ll end up eating it all! Hmmmmm….maybe I’ll need to rethink that! 🙂

    1. Hey, eating all of this pie yourself wouldn’t be the worst thing in the world. Haha! Of course, you might end up with a bellyache. Oops. I highly recommend the sugar cookie dough on top. It makes for one amazing pie! Now I want to try this with other fruits…yum!

    I’m so in for this one. I love the top “crust” on this and so fun to make it with all sorts of summer berries and fruits. Happy 4th of July weekend, David. 🙂 ~Valentina

    1. Using sugar cookie dough as a “crust” was the best decision ever, Valentina! It’s such a fun twist, and the flavor is out of sight good. 🙂 Hope you had a great holiday weekend, my friend!

  4. 5 stars
    I haven’t ever seen a slab pie before and I could not love this idea anymore. It is brilliant, David!! Easier to assemble and serve!
    Blueberries are one of my most loved things to include in a dessert. I love that cookie crust too – just delicious!!

    1. Slab pies are SO easy to make, Alex. They make a lot of pie, so they’re ideally suited for large gatherings…or if you want a lot of leftover pie. (Hey, leftover pie isn’t a bad thing at all!) And the cookie crust here? Oh man, that takes it to a new level for sure! 🙂

  5. 5 stars
    WOW David! This certainly looks like the perfect slab pie. And what better treat to celebrate the 4th with??! I am loving that sugar cookie topping, what an excellent idea. 😋. Definitely wishing I had a slice of this right now yum! Although I must admit, this is the kind of treat I can see myself enjoying quite a bit more than one slice of. 😆 Happy 4th!

    1. This slab pie really is – err, was – perfect for celebrating the 4th! We’ve had such great berries here lately. Fortunately, you can totally use frozen berries for this slab pie and save the fresh ones for snacking. However, I might’ve also snacked on a piece or 3 of this slab pie, too. Haha! Hope you had a great holiday weekend, my friend!

    How have I never even heard of a slab pie? This is such a fabulous idea, David. I love the idea of a sugar cookie crust too – I bet that elevates this pie to a party favourite. And the blueberry filling – yum! I am thinking I might need to come over for one of your parties when we’re allowed to have them again – I bet I would not walk away disappointed!

    1. I’m with ya, Katerina! A slab pie is perfect party food. Of course, slab pies are really only good for parties…unless you want to end up with a LOT of leftover pie. Of course, leftover pie isn’t the worst thing in the world, is it? 🙂

  7. Hey David, I do love a slab pie. And blueberries are one of my favorite things! I was interested to read that you feel that crust is one of the best parts of the pie. I don’t think of that as a particularly American thought, David. I should bring this to the attention of the cultural authorities, but I’m sure they’re already on the case. I already hear rumors of mask-wearing, socially-distant protests forming in front of your house. I usually think of a good crust as being something hard to come by, and that most American pies are filling-focused. I’m biased, though, because I grew up with Polish pastries that truly – even shockingly – are crust-focused. And I love those pastries. Which makes me feel sure that I’d love your slab pie, and would gladly force my way through the protests to loot your kitchen for a square of sugar cookie baked in blueberries … I mean, come on! That sounds amazing.

    1. You know, you make a valid argument here, Jeff. I’m not saying I agree with you, but I do recognize that your argument has merit and is well constructed. However, you’re wrong. 🙂 You can lead the socially-distant protest in front of my house. I’ll gladly make another one of these slab pies and sit in my front yard eating it while waving to you. Haha! Just kidding, of course. If you made your way here, I’d be forced to feed you. After all, a slab pie feeds a lot of people – maybe all of the protesters? (Nah – they don’t get any!)

  8. Although this looks fantastic and I want to make it, I just am not good at making a lot of stuff from scratch. Can I use the pre-made pie crusts and a pouch of sugar cookie mix for the top and bottom?

    1. Hey Patty! You could absolutely use pre-made pie dough and sugar cookie mix for this recipe. I haven’t done it myself (yet), but I’m certain it will work out just fine. Happy baking! 🙂

      1. Thank you, David. It might not be quite as scrumptious as yours, but I’m sure my husband will still eat it all. 🙂

  9. this looks sweet and delish david. unlike you i am less of a pastry fan – i like more filling! just like my cakes – i like a bit of cake with my icing:) great idea to use blueberries.

    1. Well, I can say with 100% certainty that this berry filling is delicious! Maybe just use half the amount of dough for your version? 🙂 Also, you sound like Laura – she always says that cake is just a vessel for frosting. Hah!

    This blueberry slab pie with sugar cookie crust looks amazing. A great dessert recipe for feeding a crowd. Love this idea. Haven’t made a slab pie before but definitely will have to give it a go. Looks like I could easily freeze any leftover too. Yummy!

    1. Slab pies are perfect for feeding a crowd…or for stocking your freezer! If you cut the pieces up before you freeze ’em, then you could totally just pull out 2 slices for dessert one night. Actually, you might be onto something here, Neil. I should do that so that we have easy portion-controlled desserts for our weekend nights!

    I lovelovelove that you topped your pie with sugar cookie dough! I’m pretty sure the only way to improve on blueberry pie is to add cookies :). This is such a beautiful dessert and now I’m wondering if I should make one for myself and just plan on eating nothing but pie for the next week. . .

    1. I’m with ya, Kelsie. I mean sugar cookies are delicious in their own right, but use those sugar cookies as the top to a pie? Mmmm….

      Also, I wouldn’t blame you one bit if you just want to eat pie all next week. That is completely acceptable. 🙂

    To be honest, I rarely turn my oven for baking sweet stuff in summer. The major exception would be crumbles and crisps, we just love them for the ratio of the filling (a lot!) to the topping (And it’s also a failure-free kind of cake.) I also bake donuts and occasionally lavender cookies and fruit cheesecakes. Well, I guess I do turn my oven in summer too, after all! 🙂 Anyway, I love this Slab Pie with the luscious blueberry filling; I’d say this is the sibling of a crisp – a little bit different ratio of the dough to filling yet still easy to make and so delicious!

    1. I totally agree with you about crumbles and crisps…they’re pretty much fool-proof. Plus, the crumble topping is the best part! It’s kinda like this slab pie. The blueberry filling is awesome, but the sugar cookie topping? The best!! I highly recommend turning your oven on for this one!

  13. 5 stars
    A slab pie, you say? Yeah, this is totally up my alley! Love how fuss free it is, but still all the flavour! Plus, for some reason, ‘slab pie’ sounds kinda fun! I bet this would be awesome with a scoop (or three) of ice-cream 😉

    1. This is totally a fuss-free dessert! And it has sugar cookies all over the top of it. That’s my kinda pie! 🙂 (And, yes, ice cream is highly recommended here!)

  14. Oh my goodness! THIS is making me so hungry! I gotta admit, i had never heard of a slab pie or sheetcake pie before this and gosh! What a thing of delicious beauty! I’m firing up my drone and sending it over to snoop around your kitchen to find any leftovers of this… at least until I move into the house down the street from y’all- then I’ll just pop on by and snoop around myself!

    1. Oh there are plenty of leftovers of this slab pie, Shashi! I mean I love blueberry pie (and that sugar cookie crust!), but I can only eat so much pie. I’ll gladly take the help! And I’ll also make you another one as your house warming present. 🙂

    1. Oh, you’ve totally got to make a slab pie soon then, Nicole! (Maybe wait until a family gathering…it’s a lot of pie. Haha!) But the sugar cookie crust? That’s a requirement! 🙂 Can’t wait to check our your summertime pie. Yum…pie!
