Blackberries, or any berries for that matter, are in season right now. However, this phenomenal treat can be made any time of the year because it calls for pie filling, rather than fresh picked berries. The beauty of this is that you can use your own homemade pie filling from the blackberries you picked or purchased in the summer, or simply grab a can off your grocer’s shelf and put this together.
This can easily be served as a dessert or a breakfast danish. It’s really easy to put together, does not require a pastry crust, and whips together like a cake batter or cookie dough. The glaze will seem a bit tart to you if you taste it before combining it with the squares, so don’t be concerned, and certainly don’t add anymore sugar! The tartness of the glaze pairs beautifully with the sweetness of these squares and you’ll be disappointed if you substitute anything for the lemon juice. Trust me on this. :)
I made this on Friday and took it to our camper. I gave a few squares to our camping neighbors, who raved about it, and we devoured more than half the pan ourselves. Everyone in the family enjoyed this one! I brought it home and shared the other half of the pan with some more neighbors.
I’m certain you could substitute any pie filling you like, so use whatever your favorite is. The cherry tree down the street is about ready for me to start harvesting, so I WILL be making this again with some homemade sour cherry pie filling. Mmmm! I hope to add to my arsenal of sour cherry recipes soon!
Blackberry Pie Squares
1 3/4 cups sugar
1 cup unsalted butter (2 sticks)
1 teaspoon pure vanilla extract
3 cups unbleached all purpose flour
1 1/2 teaspoons baking powder
21 ounces blackberry pie filling
1 1/4 cups powdered sugar
1 tablespoon unsalted butter, melted
2 tablespoons lemon juice
Preheat oven to 350 F.
Cream sugar and butter in mixer on medium speed until fluffy. Add eggs, one at a time, until incorporated. Add the vanilla and beat well. Whisk together flour and baking powder. Turn mixer speed down to lowest setting and slowly add flour mixture until completely combined.
Spread half of mixture (I actually weight mine to get even halves, cuz I’m obsessive that way) onto an ungreased 15×10 jelly roll pan. Spread pie filling over the top of the batter. Drop remaining batter onto the pie filling layer by spoonfuls.
Bake for 45 minutes or until golden brown. Do not under bake. Remove to a wire rack.
Combine powdered sugar, melted margarine and lemon juice and drizzle over warm bars.
Allow to cool completely before cutting into squares.
