3-Ingredient Lemon Bars

These 3-ingredient lemon bars are the dessert my mother-in-law insists I bring to every family gathering—and she’s right, they vanish before the main course ever hits the table. This is a very Midwestern, potluck-friendly shortcut recipe that leans on a boxed lemon cake mix and canned lemon pie filling to deliver bright citrus flavor with almost no effort. Melted butter transforms the cake mix into a soft, crumbly crust and topping, while the pie filling bakes into a glossy, vibrant yellow layer. It’s the kind of practical, crowd-pleasing recipe busy home cooks keep in their back pocket for holidays, church suppers, and last-minute invitations.

Serve these lemon bars chilled or at room temperature, cut into small squares so they’re easy to grab from the glass baking dish on a buffet. They pair nicely with hot coffee or black tea, which balances the sweetness and bright lemon flavor. For a more complete dessert spread, offer a bowl of fresh berries or a simple fruit salad alongside. If you’d like something creamy, a small dollop of lightly sweetened whipped cream on each bar works well, but they’re designed to stand on their own—especially at casual gatherings where people are nibbling as they chat.
