Buttery shortbread, creamy lemon filling, and that perfect sweet-tart balance, these Lemon Cream Cheese Bars are the kind of dessert everyone asks for the recipe. Simple ingredients, foolproof method, and absolutely irresistible.
Prep the pan and oven: Preheat oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides. Lightly grease.
Make the shortbread crust: In a large bowl, mix butter, flour, powdered sugar, and salt until a soft dough forms. You can also do this in a food processor or a handheld mixer. Press evenly into the bottom of the prepared pan. Bake for 10 minutes. Remove from oven.
Make the filling: In a large bowl, using an electric mixer, beat cream cheese, granulated sugar, and cornstarch until smooth. Mix in flour, lemon zest, and lemon juice. Add eggs, one at a time, mixing just until combined. Stir in vanilla.
Bake: Pour filling over the warm crust. Bake for 30-35 minutes, or until the center is set.
Cool and chill: Let cool at room temperature for 30 minutes, then cover and refrigerate for 4 hours or overnight.
Slice and serve: Lift bars out using the parchment or foil. Slice into squares, dust with powdered sugar, and serve.
Notes
Chill fully before slicing for clean, bakery-style bars.
Bake the crust just until set—not browned—to keep it tender.
Mix the filling just until smooth; overmixing adds air and can cause cracks.
Don’t overbake—the center should be set but not dry.
