Blackberry Crumb Bars


Delight picnic-goers with a portable version of summer berry crumble: a perfect marriage of tart fruit and tender cake, capped with a slightly crunchy topping.

  • Total Time:
  • Yield: Makes 16

Source: Everyday Food, June 2008


  • 6 tablespoons unsalted butter melted, and 1/2 cup (1 stick), room temperature, plus more for pan
  • 1 3/4 cups all-purpose flour (spooned and leveled), plus more for pan
  • 1/2 cup packed light-brown sugar
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 cup confectioners' sugar
  • 1/2 teaspoon pure vanilla extract
  • 2 large eggs
  • 2 containers (5 ounces each) blackberries


  1. Preheat oven to 350 degrees. Butter an 8-inch square baking pan. Line bottom with parchment paper, leaving an overhang on two sides; butter and flour paper, tapping out excess.

  2. Make topping: In a medium bowl, whisk together melted butter, brown sugar, and 1/4 teaspoon salt; add 1 cup flour, and mix with a fork until large moist crumbs form. Refrigerate topping until ready to use.

  3. In a medium bowl, whisk together remaining 3/4 cup flour, baking powder, and remaining 1/4 teaspoon salt; set aside. In a large bowl, using an electric mixer, beat room-temperature butter, confectioners' sugar, and vanilla until light and fluffy; add eggs, one at a time, beating well after each addition. Reduce speed to low; mix in flour mixture. Spread batter evenly in pan; sprinkle with blackberries, then chilled topping.

  4. Bake until golden and a toothpick inserted in center comes out with moist crumbs attached, 40 to 45 minutes. Cool completely in pan. Using paper overhang, lift cake onto a work surface; cut into 16 squares.

Cook's Notes

While you prepare the cake, refrigerate the crumb topping. This will help give it a nubbly texture once baked. To store, keep in an airtight container at room temperature, up to 3 days.

    question....approx how many cups of blackberries does this recipe take? i just bought some from the farmers market and they are loose, not in containers. i'm assuming the 5 oz is related to weight and i don't know how to weigh them.

    This was so easy to make and one of the best desserts ever. I used Fleur de Sel in the crumbly top and it's PERFECT. Warning: these are too addictive!!

    So easy and it got rave reviews from all who consumed it. I was impressed the crumble stayed crunchy overnight. Really yum and I will be making it again for sure.

    So quick, easy and delicious! I will definitely make this again using fruits of the season. I have made the Rhubarb Crumb, which is the exact cake and crumb topping ingredients, difference being the fruit, sweetener and thickener. The Rhubarb recipe is a bit easier to follow while cooking, in my opinion, as the crumb topping ingredients are listed separately from the cake ingredients. I like baking but don't like doing division at the same time!

    the amount of grams per cup is entirely dependent on its contents. ie. flour, different types of sugar, butter etc. will all have a different weight per cup. a cup is a measurement of capacity not a measurement of weight. a cup is roughly 225mls, so if you were to measure a cup of sugar, for instance, you could pour sugar into a measuring jug up to the 225ml mark, and that would equal a cup of sugar.
