These Lemon Pistachio Cheesecake Bars start with a lemon cookie–pistachio crust, topped with a silky-smooth lemon cheesecake layer with pistachio cream mixed in! Bright, tart, creamy, and refreshing, they’re absolutely irresistible—perfect for any lemon lover!
Preheat oven to 350℉. Line an 8x8 baking pan with aluminum foil. Set aside.
Place the lemon cookies and pistachios in a food processor or blender. Pulse until finely ground. Place in a medium mixing bowl and add the melted butter. Stir until combined and completely moistened. Evenly press the crust mixture into the prepared pan. Bake for 8 minutes until lightly golden on the edges. Let cool while you make the filling.
Make the filling. Add the softened cream cheese to the bowl of a stand mixer fitted with the paddle attachment. Add the sugar and beat until combined, 1-2 minutes. Add the pistachio cream and beat for another minute, scraping down the sides as needed. Add the lemon zest and juice, eggs, and vanilla extract. Beat for another 1-2 minutes, scraping down the sides as needed. Add the flour and salt and mix once more until smooth and combined.
Pour filling onto the baked crust, smoothing out the top until even. Bake for 37-40 minutes, until edges are golden brown, and center is set, and just barely jiggles when you move the pan. Let cool completely in the pan on a wire rack. Once completely cool, place bars in the fridge for 4-6 hours. Once bars have chilled, run a sharp knife under hot water and cut the bars into 9 squares. Garnish with crushed pistachios and little slices of lemon. Serve!
