Blueberry Slab Pie - the best way to take a pie to a potluck! Easy to make, easy to serve, and easy to eat!

I have this sweater that I pull out once the weather turns below 60 degrees. It’s an old college sweater of mine. It’s an XL so it’s baggy, the perfect thickness from years of washing, and it doesn’t have a hood so it doesn’t get all funky up on my back while I lay on the couch and eat bon bons all day.

The sleeves are a little ripped; there are now thumbholes in the wrists, perfect so that I can pull the sleeves over my hands to keep them warm but still use my thumbs to text. It has a hole in the chest where my pet rat (don’t ask, I was 20) chewed on it. And, it’s splattered with purple puffy paint from a poster project when I was in my late 20s.

So really, if I was a man, this sweater would be one of those things that my wife threw away in the middle of summer, hoping I’d forget about it by November when the weather cooled off.

I know, doesn’t the visual of me in my sweater make you think I’m a total hottie? Gee, you’re thinking. No wonder she only has one kid!


Let’s talk about slab pie, shall we?

Slab pie is genius, really. It’s a pie in a bar form. Much easier to cut and serve, and it serves a lot of people. Really, it’s just a pie…but in a sheet pan instead. I used a jelly roll pan, You could use a 9×13″ pan. Or, make this as a regular pie.

Any way you make this pie, it’s going to be delicious.

I used the crust recipe from my Funfetti Cookie Pies and the topping from my Apple Butter Pie Bars. To make life easier, I used a can of blueberry pie filling. Oh, and let’s not forget the white chocolate chips I sprinkled on top. Because white chocolate and blueberry are BFFs.

This pie is indescribable, except to say YUM. It was SO good. I ate way too much of it myself. It was part of the bake sale, and it sold fast.

If you’re feeding a lot of people this Thanksgiving and need an easy pie…make this one. You’ll be glad you did!

And, if you happen to have an old XL college sweater, no one will notice the difference after you’ve eaten half a slab pie. Baggy is good, people. ๐Ÿ˜‰


Did you make this recipe?

Blueberry Slab Pie

Slab pie is so much easier to serve! This one has a scratch crust and a crumble topping and is full of blueberry pie filling!


For the Crust:

  • 2 1/2 cups flour

  • 1/2 teaspoon salt

  • 1 cup butter, diced and cold

  • 2-3 tablespoons ice water

  • 1 tablespoon vinegar

For the Filling & Topping:

  • 1 can ( 21 oz) Blueberry Pie Filling

  • 1 cup white chocolate chips

  • 1/2 cup (1 stick) butter, softened

  • 1 cup flour

  • 1/2 cup oats

  • 1/2 cup sugar


  1. Make your crust: Pulse flour and salt in a food processor for a second. Add butter and pulse until butter has been worked through the flour. Add vinegar and pulse. Add water, 1 tablespoon at a time, until the dough comes together (I used 2 tablespoons water). Wrap dough in plastic wrap and chill for 30 minutes or as long as overnight.

  2. Preheat oven to 350 degrees. Spray a jelly roll pan (mine is 10x15) with cooking spray.

  3. When ready to make pie, unwrap chilled dough. Roll into a large rectangle. Press into the bottoms and up the sides of your pan.

  4. Spread blueberry pie filling evenly over the crust. Sprinkle with white chocolate chips.

  5. Using a hand mixer, mix remaining topping ingredients (butter, flour, oats, and sugar) in a large bowl. You may need to use your hands to break up the large bits of butter. Sprinkle over the top of the blueberry filling and press to compact.

  6. Bake for 30-40 minutes until topping begins to brown. (The blueberry might bubble over a little so you may want to place something on the rack underneath your pan.) Cool before cutting.

    Oh, and I have more than one old sweatshirt leftover from my college days. Still the comfiest things I own.

  8. This is a genius idea. Who needs pie in a pie pan? Bars make more anyway!
    I wear giant sweatshirts and sweatpants all the time. Much to my husband’s dismay. Hey, he’s the one that moved me to Alaska.

  9. I just bought some blueberries today, and since I don’t have blueberry pie filling maybe I can make these yummy little pies with the fresh ones!

  10. Slabs pies are meant for crust lovers like me. Plus the blueberry filling is right up my ally! I’ll have to bring this pie to thanksgiving dinner for dessert. My whole family will go nuts over it!

  11. hooded sweaters = SO annoying when you’re sitting down… yes! you took the words right outta my mouth. i love hoodless sweatshirts, i’m literally wearing my favorite green striped one right now! i’ve only made a slab pie once and that was years ago! i need to do it again. and blueberry sounds SO good right now, i haven’t had any since the summer ๐Ÿ™

  12. firstly, I love the idea of a pie like this! Second I had a hoodie like that, from when I was a cheer leader, for like 3 weeks LOL. It had the perfect thumb holes worn in so I wore it riding all the time, kept my hands warmer and I could hold the reigns so easily, I miss that hoodie:(

  13. Loooooove slab pies! This looks awesome.

  14. Blueberries are so yummy. I have zero pie making skills but I’m almost positive I could make this:) Your sweatshirt sounds almost as comfy as my maternity shirt I refuse to let go of. I won’t judge.

  15. I have a sweatshirt like that. Thumb holes & everything. Except mine wasn’t chewed on by a rat. (BTW, I think they are cute with the exception of the tail. The tail creeps me out!)

    This pie looks FABULOUS! I’m thinking of raspberry filling though…hmmmmmmm

  16. Pretty sure my hips just got bigger looking at this…how do I hide those!?

I’m only a UK size 8 (4-6 US, I think or so my Fox jeans say 4) and I bought a fleece lined hoodie off eBay in size XXXL LOL! It’s like a blanket with arms and I love snuggling on the sofa with it with the hood up. You crack me up at below 60 though. That’s UK warm, hehe.

    And blueberry slab pie? I’ll take the whole slab! I can’t be trusted with desserts like this, they make me a leetle crazy. Do you think you could make like 185,037,376 of these so I could build a house out of them and gradually chew my way through?! ๐Ÿ˜€ I just noticed we posted similar things too. I know mine are apple n’ all but still similar-ish.

  19. YUM! Looks amazing! I love blueberries. Totally pinned!

  20. I totally have one of those too! Except I stole it from Jessie, so it probably has a ton of memories for him, now abducted into my closet ๐Ÿ™‚ it also has thumb holes which are genius, methinks. Annnnnd a pet rat? Who are you, child? Anyways, I love slab pie. Bars are my favoritestthingever and pie is my second fave, and put together, they can solve many world problems. Also, blueberries + white chocolate. Helllo, awesomesauce.
