Blueberry Slab Pie

JUMP TO RECIPE

Blueberry Slab Pie slice on white doily - 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!

Anyway.

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. 😉

Enjoy!

Yield 10 servings
Serving Size

Ingredients

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

Instructions

  • 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.
  • Preheat oven to 350 degrees. Spray a jelly roll pan (mine is 10x15) with cooking spray.
  • When ready to make pie, unwrap chilled dough. Roll into a large rectangle. Press into the bottoms and up the sides of your pan.
  • Spread blueberry pie filling evenly over the crust. Sprinkle with white chocolate chips.
  • 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.
  • 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.

  1. 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:(

  2. 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 🙁

  3. 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!

  4. 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!

  5. 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.

  6. I love that blueberries and white chocolate are BFF’s in this. And I love slab pie too…more pieces to enjoy. Hey, yeah, where is the peach;-)

  7. Crust. Ha. I laugh. Okay, you do make it look and sound easy, and quite delicious. No peach though? hehehehe!!!!

  8. Okay, I totally love the idea of making pie in slab form. Because I have to tell you, as much as I love EATING pie, I’m not that great at making it. But this? I could totally do.

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