I found this recipe while searching on Pinterest. My blackberry bushes are exploding with blackberries, so I was specifically looking for blackberry dessert recipes. I found a winner on Tracey's Culinary Adventure. Her blackberry pie bars looked amazing. I just had to try them and I'm so glad I did. You should be glad too.
1 1/2 cups flour
3/4 Cup sugar
1/8 teaspoon salt
3/4 cups cold butter, cut into small cubes
2 large eggs
1 cups sugar
1/2 cup sour cream
1/4 cup + 2 tablespoons flour
pinch of salt
zest of 1/2 lemon (I didn't have a lemon to zest, so I added a few drops of lemon juice)
1/2 teaspoon almond extract (You can use vanilla if you don't like almond)
16 oz fresh blackberries
Preheat the oven to 350 F. Spray an 8x8 inch pan with nonstick cooking spray. (I was tempted to use line the pan with parchment paper, but didn't. It was fine using the spray.)
Add the flour, sugar, and salt in a food processor and pulse a few times to combine. Add the butter and continue pulsing until the pieces of butter are very small and the mixture is crumbly. Put aside 3/4 cup of this mixture. It will be used as the topping. Dump the remainder of the mixture into the pan and press into an even layer to form the crust.
Bake for 12-15 minutes or until golden and brown. Remove pan and place on a wire rack. Cool for 10 minutes.
It still amazes me that I can use a food processor to cut in the butter. It works so well.
After the crust is out of the oven and cooling, begin to make the filling.
In a mixing bowl, mix together eggs, sugar, sour cream, flour, salt, lemon zest, and almond extract. Make sure it is well combined. Use a spatula to fold in the blackberries. Spread the filling mixture over the crust. Make sure the blackberries are spread out evenly. Crumble the reserved crust mixture over the blackberry mixture.
Bake for 40-50 minutes, or until the bars are set. The topping won't really get golden brown, so no worries. When they are done, let the pan cool on a wire rack and cool completely. To make the bars easier to cut, put the pan in the refrigerator for a while.
