Equipment

1 9x13-inch pan

Ingredients

Crumb Mixture

1 1/2 cups salted butter softened
1 cup sugar
2 teaspoons vanilla extract
1/4 teaspoon salt
3 cups all-purpose flour

Blueberry Filling

1/4 cup sugar
1 teaspoon cornstarch
4 cups fresh blueberries

Icing (Optional)

1 cup powdered sugar
2 tablespoons milk

Instructions

Preheat the oven to 350℉ and line a 9x13 inch pan with parchment paper.
In a large bowl or the bowl of a stand mixer, combine the butter, sugar, vanilla, and salt.
Scrape down the sides of the bowl then stir in the flour.
Press about 2/3 of the mixture into the prepared pan and bake for 15 minutes.
Combine the sugar and cornstarch. Add the blueberries and stir to combine.
Spoon the blueberry mixture over the bottom crust and gently spread to an even layer.
Top with the remaining crumb mixture.
Bake for an additional 30-35 minutes or until golden brown and bubbly.
For the icing (optional), whisk together the powdered sugar and 2 tablespoons of milk. Add additional milk as needed to make a desirable drizzling consistency.
Drizzle over the cooled bars and enjoy.

Notes

*Increase the salt to 1/2 teaspoon if using unsalted butter.

*If using frozen blueberries, you do not need to thaw them before adding to the bars. The bars may take a little extra time in the oven to account for the frozen berries.

*Store the bars in an airtight container in the fridge for up to 3-5 days.
