A stunning four-layer no-bake dessert featuring a buttery pecan-graham crust, tangy cream cheese filling, billowy whipped cream, and jewel-toned blueberry topping. This elegant Southern classic relies on proper chilling between layers to create distinct, sliceable strata that hold their shape beautifully.
Combine graham cracker crumbs, finely chopped pecans, melted butter, sugar, and salt in a medium bowl. Stir until the mixture resembles wet sand and holds together when pressed.
Press the mixture firmly and evenly into the bottom of a 9x13-inch baking dish using the bottom of a measuring cup or glass. Refrigerate for at least 15 minutes while preparing the filling.
Make the Cream Cheese Layer
In a large bowl, beat the room-temperature cream cheese with a stand mixer or hand mixer on medium speed until completely smooth, about 2 minutes. Scrape down the sides of the bowl.
Add the sifted powdered sugar, vanilla extract, and salt. Beat on low speed until incorporated, then increase to medium-high and beat until light and fluffy, about 2 minutes.
Spread the cream cheese mixture evenly over the chilled crust using an offset spatula. Refrigerate for 30 minutes to allow the layer to set.
Prepare the Whipped Cream Layer
In a chilled bowl with chilled beaters, whip the cold heavy cream on medium speed until it begins to thicken. Add the powdered sugar and vanilla extract.
Increase speed to medium-high and whip until stiff peaks form, about 3-4 minutes total. The cream should hold its shape but still look glossy.
Spread the whipped cream evenly over the set cream cheese layer. Return to the refrigerator while preparing the blueberry topping.
Make the Blueberry Topping
In a medium saucepan, combine 2 cups of the blueberries, sugar, cornstarch, water, lemon juice, and salt. Stir to combine.
Cook over medium heat, stirring frequently, until the mixture comes to a boil and thickens, about 8-10 minutes. The berries will burst and release their juices, creating a glossy sauce.
Remove from heat and gently fold in the remaining 2 cups of fresh blueberries. Allow the topping to cool to room temperature, about 30 minutes.
Spoon the cooled blueberry topping evenly over the whipped cream layer. Refrigerate for at least 4 hours, or preferably overnight, before serving.
Serve
Cut into squares using a sharp knife dipped in warm water and wiped clean between cuts. Serve chilled directly from the refrigerator.
Notes
For the cleanest cuts, refrigerate the dessert overnight. The layers will be fully set and slice beautifully.Room temperature cream cheese is essential. Cold cream cheese will result in a lumpy filling that never fully smooths out.The crust can be made with all graham crackers if you prefer, though the pecans add depth and a more interesting texture.Substitute an equal amount of frozen blueberries for fresh in the cooked portion of the topping if needed. Keep the fresh berries for folding in at the end.
