Blackberry Crumb Bars

Ever since I made that Berry Tart, I’ve been wanting to bake something else with blackberries. Raspberries seem to be my berry of choice, but those blackberries in that tart really had me wanting to stray a bit from the usual.

Of course, berry crumb bars don’t exactly qualify as straying from the usual. This isn’t groundbreaking territory. But, it’s one of those desserts that never seems to go wrong.

I wasn’t expecting any surprises with this recipe, but I did get a little one. The bottom layer, which I had assumed would be mostly crunchy like a cookie base, was not like I expected it all. It was soft and dense, like cake.

I’m not sure I like one way more than the other, but it was a break from the norm. It seemed to dress these up immediately, taking them from a low-key dessert to a dinner table dessert. A little (or big) dollop of ice cream, and you’ve got a wonderful summer dessert.

These buttery blackberry crumb bars are made with brown sugar, vanilla and fresh blackberries. An easy dessert bar recipe for summer!

Blackberry Crumb Bars


  • 6 tablespoons (85g) unsalted butter, melted
  • 1 & 3/4 cups all-purpose flour, divided into 1 cup (120g) and 3/4 cup (90g)
  • 1/2 cup (100g) firmly packed light brown sugar
  • 1/2 teaspoon salt, divided into 1/4 teaspoons
  • 1/2 teaspoon baking powder
  • 1/2 cup (113g) unsalted butter, softened
  • 1 cup (110g) confectioners’ sugar
  • 1/2 teaspoon vanilla extract
  • 2 large eggs
  • 10 ounces (284g) blackberries


  1. Preheat oven to 350°F. Butter an 8-inch square baking pan. Line the bottom with parchment paper, leaving an overhang on two sides. Butter and flour the paper, and tap out the excess.
  2. Whisk together the melted butter, brown sugar, and 1/4 teaspoon salt. Add 1 cup of the flour and mix with a fork until moist crumbs form. Refrigerate.
  3. Whisk together the remaining 3/4 cup flour, baking powder, and 1/4 teaspoon salt. Set aside.
  4. Using an electric mixer on medium speed, beat the butter, confectioners’ sugar, and vanilla until light and fluffy. Add the eggs, one at a time, mixing well after each addition.
  5. Reduce mixer speed to low, and mix in the flour mixture just until combined.
  6. Spread the batter evenly in the prepared pan. Sprinkle with blackberries. Then, sprinkle with the chilled topping.
  7. Bake 40 to 45 minutes, or until golden. A toothpick inserted in the center should come out with moist crumbs attached.
  8. Cool completely in the pan on a wire rack. Then, remove from the pan using the overhanging parchment paper and cut into bars.
