Blueberry Crumble Bars


Prep Time: 20 minutes  | Cook Time: 40 minutes  | Servings: Servings: 15 


This recipe is from a site called Cooking Classy.  It is modified only slightly.  A delightfully easier and more portable version of blueberry crumble.



3 cups all-purpose flour (spoon and level)

1/2 cup granulated sugar

1/2 cup brown sugar

1 tsp baking powder

1/4 tsp salt

1 large egg

1 1/2 tsp vanilla extract

1 cup plus 2T butter, chilled and cut into cubes


1 Tbsp cornstarch

1/2 cup granulated sugar

Zest of one lemon

3 Tbsp lemon juice

4 cups fresh blueberries, at room temperature


Preheat oven to 375 degrees F. Butter a 9×13-inch baking dish.  I like to line the dish with a parchment paper sling (parchment that hangs over the side of the dish) and butter the parchment paper as well. This will allow you lift the bars out easier after baking.  Set prepared dish aside.

In a large mixing bowl whisk together flour, 1/2 cup granulated sugar, brown sugar, baking powder and salt.

In a small mixing bowl, whisk together egg and vanilla until combined.

Add egg mixture and cold butter cubes to flour mixture and using a fork or a pastry cutter, cut mixture together until it resembles coarse crumbs.

Press 1/2 of the mixture evenly into prepared baking dish.

In a separate mixing bowl, whisk together remaining 1/2 cup granulated sugar and cornstarch, stir in lemon juice.

Add blueberries then toss mixture to evenly coat, pour and spread coated blueberries evenly over crust in baking dish.

Sprinkle remaining crumb mixture over berry layer.

Bake in preheated oven about 38 – 42 minutes until top is golden brown.

Allow bars to cool for about 20 – 30 minutes before lifting out of the pan and cutting into squares.

Store cooled bars in an airtight container in refrigerator (rewarm in microwave for 10 – 15 seconds if desired).


The crust mixture will look a little like sand and be dry.  Never fear, the butter will bring it together in the oven.

You could easily change up this recipe by using another fresh berry.


Happy Eating!!
