What Are Blueberry Bars?

Blueberry Crumb Bars are a delicious fusion of blueberry pie and blueberry crumble. It has a buttery crust, just like pie. It boasts a tantalizing blueberry filling in the center, similar to both pies and crumbles. Yet it incorporates the mouthwatering crumble topping characteristic of crumble desserts. Essentially, it’s the best of both worlds.

What You’ll Love

  • These Blueberry Bars boast a big load of fresh blueberries, bursting with juicy sweetness.
  • The top and bottom layers consist of a buttery bottom crust and crispy topping that’s infused with fragrant cinnamon.
  • It can be made entirely in advance; in fact, it should to be cooled completely in order to set.
  • Blueberry Crumb Bars are fabulous served chilled or re-heated. Hubby and I are torn on this one; I prefer my bars chilled, while he is adamant that reheated in the toaster oven is the way to go.
  • Whichever way you choose, chilled or warmed, these bars are amazing with a scoop of ice cream.

Nuts are a great addition to the topping, for both crunch and extra nutrition. Toasted chopped walnuts and pecans are favorites. Roasted sliced almonds can also be used.

For the Crust & Topping:

For the Filling:

  • 4 cups fresh blueberries
  • ½ cup sugar
  • 4 tsp cornstarch
  • Freshly squeezed juice of 1 lemon, approx. 3 TB


  • Prepare: Preheat oven 375F with rack on lower middle position. Grease a 9×13 baking pan and set aside.
  • Make the Crust/Topping: In a bowl, hand-whisk the flour, sugar, cinnamon, baking powder, and salt. Use a pastry cutter to cut in the cold butter. Add the egg and continue to cut in with pastry cutter until dough becomes a crumbly consistency. Evenly press half of the dough into greased pan (see video for tips.)
  • Make the Filling: In a large bowl, hand-whisk together the sugar, cornstarch, and lemon juice. Use a rubber spatula to gently fold in the blueberries to coat. Softly spread blueberries evenly over crust, including excess juice from the bowl. Evenly sprinkle remaining topping dough over the blueberry layer.
  • Bake: Bake 45-50 min or just until topping is golden brown. Let dessert cool completely at room temp before cutting into squares (may be easier to cut when chilled) Serve bars chilled or re-heated, with ice cream or freshly whipped cream.
