Triple Berry Pie Squares

I had decided to make Wild Blackberry Pie Squares, so I got to work on putting the crust together.  After I was done with that, I went to wash the blackberries.  That’s when I noticed a tiny white worm munching its way through one of our beautiful berries.  I picked that berry out of the bunch, hoping that was the only one, then scoured the rest of the berries very carefully.  That’s when I noticed another, then another, and another.

I yelled out to my hubby, “These berries are full of worms!!”  He was so heartbroken, and so was I.  Those berries looked so delicious, and I had already made my pie crust, which was just sitting there, waiting to be covered in beautiful wild blackberries.

Angrily, I tossed the blackberries in the garbage can.  John knew how upset I was.  I was already having a bad day, and this was just the icing on the cake.  So, he offered to go to the store to get more berries.  He was going out to pick up a pizza anyway, because I had burned our chicken dinner.  Like I said, bad day.  I also woke up this morning, COVERED in mosquito bites from our little adventure outside yesterday.

When John came back from the store, he delivered a package of blackberries, a package of raspberries and a package of blueberries to me.  He said the blackberries were a bit on the expensive side, and the raspberries and blueberries were cheaper, so he just decided to get a package of each of those instead of three packages of blackberries.  That was fine by me.  I’ll never turn any kind of berry down!

I actually think the mixture of berries adds a depth of flavor to these pie squares, that wouldn’t be there with just a single berry.  If you want to use just a single berry, that would work well too though.

Crust and Topping:

  • 3 cups all purpose flour
  • 1 cup granulated sugar
  • 1 tsp. baking powder
  • 1 cup 2 stickscold butter
  • 1 egg
  • 1/2 tsp. salt
  • 1 tsp. cinnamon
  • 1 tsp. vanilla

Fruit Filling:

  • 1 cup blackberries
  • 1 cup raspberries
  • 2 cups blueberries
  • 4 tsp. cornstarch
  • 1/2 cup granulated sugar


  • Preheat oven to 375 degrees.
  • Grease a 9 x 13 baking pan.
  • In a large bowl, combine flour, 1 cup of sugar, baking powder, salt, and cinnamon.
  • Cut in 2 sticks of cold butter, and incorporate into flour mixture with a fork or pastry cutter until it’s crumbly.
  • Add egg and vanilla, and combine into flour mixture until it forms a dough-like crust mixture.
  • In a separate bowl, combine berries, 1/2 cup granulated sugar and cornstarch. You could add a little lemon juice to this for added flavor, but I didn’t have any on hand, so I didn’t.
  • Take 1/2 of your crust & topping mixture and pat it into the bottom of your greased 9 x 13 baking pan.
  • Spread berry mixture evenly over the top of the crust.
  • Sprinkle the remaining crust & topping mixture evenly over the berry mixture.
  • Bake in 375 degree oven for 35-40 minutes.


These pie squares taste great all warm out of the oven, but I think they taste even better when they have been cooled in the fridge for a few hours. It also makes cutting them into squares much easier!
