Be still my heart, these blackberry pie bars are everything! Let me count the ways: rich and buttery crumbs envelop a sweet and jammy blackberry filling. With plenty of butter, lemon zest, and vine ripened blackberries, these bars are the very essence of blackberry pie, albeit in an all too effortless crumb bar.

Blackberry Pie Bars

These blissful blackberry crumb bars will be on repeat for what remains of summer, the epitome of everything I love about the season: carefree, breezy, simple, and oh so delicious.

How to make blackberry pie bars:

What I love most about these bars is that the crust and crumbs are one simple dough that comes together in under 5 minutes (thank you, melted butter!).

  • Reserve 3/4 cup of the dough for the crumb topping (keep chilled), and press the remaining dough evenly and firmly into the prepared baking pan.
  • Bake the crust until golden, then let cool slightly before adding the blackberry filling and reserved crumbs.
  • Continue baking until the topping is golden and the blackberry filling is slightly bubbly. Let bars cool completely before slicing and serving.
  • Need dessert for a large group? Simply double the recipe and bake in a 13 x 9-inch baking pan.

  1. This is excellent. I used more blackberries than called for because I have so many. Best blackberry dessert I have found!

  2. I was so happy to find this recipe after I purchased 2, 6 oz. packages of fresh blackberries on sale at the market in the middle of January in New York! I was even happier that these bars came out so delicious and that the amount of blackberries I had (12 ounces) were more than enough for the filling. Thanks, Laura and Happy New Year!
