Instructions

Bake the crust: Preheat the oven to 325°F and lightly grease a 9×9-inch metal baking pan. In a medium bowl, whisk together the pecan flour, toasted chopped pecans, powdered sweetener, cinnamon, and kosher salt. Stir in the melted butter until the mixture clumps together like wet sand. Press the dough firmly and evenly into the bottom of the prepared pan. Bake for 15 to 18 minutes, until the edges are lightly golden brown. Set aside to cool completely.
Cook the blueberry topping: In a medium saucepan, combine 1 ½ cups of the blueberries, the granulated sweetener, and the water. Place over medium heat and bring to a simmer. Cook for about 7 minutes, gently mashing the berries with a wooden spoon as they soften.
Finish the topping: Remove the saucepan from the heat. Stir in the remaining ½ cup of fresh blueberries, lemon zest, and lemon juice. Evenly sprinkle the xanthan gum over the top, immediately whisking vigorously to incorporate without clumping. Let the mixture cool to room temperature.
Whip the cream cheese: In a large mixing bowl, beat the softened cream cheese and powdered sweetener until completely smooth and creamy. Add ¼ cup of the heavy whipping cream and beat again just until lightened and fully incorporated.
Whip the heavy cream: In a separate bowl, whip the remaining 1 cup of heavy whipping cream and the vanilla extract until it holds stiff peaks. Gently fold the whipped cream into the cream cheese mixture using a rubber spatula until no streaks remain.
Assemble and chill: Spread the vanilla cream filling evenly over the cooled pecan crust. Pour the cooled blueberry topping over the cream layer, spreading it gently to the edges. Refrigerate for at least 3 hours to set the layers completely before slicing into bars.

Notes

Why It Works

Adding a pinch of cinnamon to the crust enhances the warm, nutty notes of the pecans.
Reserving a portion of the blueberries to add off the heat ensures the topping maintains a beautiful texture with some whole, fresh berries intact.
A splash of fresh lemon juice balances the sweetener and naturally brightens the berry flavor.

Common Pitfalls to Avoid

Warm crust: Ensure the crust is 100% cooled before adding the cream layer, or the cream cheese will melt and separate.
Cold cream cheese: Using cream cheese straight from the fridge will result in a lumpy filling. Leave it out for at least 1 hour before mixing.
Clumpy thickener: Sprinkle the xanthan gum across the surface of the blueberry sauce rather than dumping it in one spot to prevent gelatinous lumps.

Variations

Nut-Free Crust: Swap the pecan flour and chopped pecans for sunflower seed flour and toasted shelled sunflower seeds.
Mixed Berry: Substitute half of the blueberries with fresh raspberries or diced strawberries.

Allergy Alert
