‘Bright favorite’: Just 4 ingredients. I don’t even check the recipe anymore.

For a slightly more complex crust, you can swap in vanilla wafer cookies or shortbread in place of graham crackers; they’ll give a more buttery, cookie-like base while keeping the ingredient count simple. If you enjoy a stronger citrus profile, use a mix of lemon and lime juice, or add a bit of finely grated lemon zest to the filling (just be sure to zest before juicing). For a lighter texture, fold in a few spoonfuls of plain Greek yogurt to the cream cheese mixture—this adds a subtle tang and softens the richness. To make these bars more potluck-friendly, line the pan so the parchment fully covers the bottom and two sides; it makes removal and transport easier and keeps the crust intact. When slicing, use a long, sharp knife dipped in hot water and wiped dry between cuts for clean edges. Finally, if you like a contrasting finish, top the chilled bars with a thin layer of lemon curd or a scattering of fresh berries just before serving; both options highlight the lemon flavor without complicating the base recipe.
