Serves 12
15m prep time
20m cook time
1h inactive


3 1/2 cups fresh blueberries, divided
1/3 cup granulated sugar
3 tablespoons brown sugar
1 tablespoon water
1 1/2 tablespoons cornstarch
1 teaspoon lemon zest
1/2 teaspoon lemon juice


3/4 cup butter, melted
2 cups all-purpose flour
1 cup pecans, finely chopped


2 cups heavy whipping cream
2 cups powdered sugar
16 oz cream cheese, at room temperature
1 teaspoon vanilla


First, make the topping:

In a large saucepan over medium-high heat, add 2 cups of the blueberries, both sugars, and mix until sugar has dissolved.

In a small bowl, stir the cornstarch into the 1 tablespoon cold water, then pour into the blueberry mixture. Stir until thickened.

Add lemon zest, stir to combine, and remove from heat. Stir in remaining blueberries. Transfer to a bowl and let cool 5 minutes before transferring to the fridge to cool completely.

While blueberry topping chills, make the crust:

Preheat oven to 325°F and grease a 9×13-inch baking dish with nonstick spray.

In a medium bowl, stir together the melted butter, flour, and chopped pecans until well combined. Press mixture evenly in bottom of prepared baking dish.

Bake crust for 15 minutes. Remove from oven and let cool while you make the filling.

In a large mixing bowl, whip the heavy whipping cream and vanilla until starting to thicken. Gradually add powered sugar and continue beating until thick, but not stiff.

In a separate bowl, beat the cream cheese until smooth. Fold whipped cream mixture into cream cheese until combined.

Spread mixture over cooled crust, then top with chilled blueberry topping.

Chill until ready to serve, at least 1 hour. Enjoy!
