Ingredients for lemon supreme pie bakers square copycat

Buttery crust, tangy lemon curd, and velvety vanilla cream—just eight ingredients deliver bakery-quality pie.

The crust starts with cold butter—never softened—because that's what creates the flaky layers. European-style butter like Plugrá or Land O'Lakes works best, but any unsalted will do. Sift the flour and sugar together first to avoid lumps, then cut in the butter using a pastry cutter or your fingers until it resembles coarse crumbs. The ice water is key here: add it gradually until the dough just holds together when pressed. Overmixing kills the flakiness, so handle it as little as possible. For the lemon curd filling, fresh lemon juice is non-negotiable—bottled juice lacks the brightness. Use a microplane for the zest to get fine, fragrant strips without the bitter pith. And always zest your lemons right before using; it loses potency fast.

No cornstarch? A 1:1 swap with arrowroot powder works, though the curd might thicken slightly differently. Short on egg yolks? Duck eggs add richness, but chicken yolks are fine if you use an extra one. The vanilla cream can be made ahead, but the egg whites need to be at room temperature—cold whites won't whip properly. For a lighter texture, fold in the powdered sugar gradually while whipping. The lemon curd should coat the back of a spoon but still be pourable; if it's too thick, thin it with a splash of milk. And if you're worried about the crust browning too quickly, cover the edges with foil after 20 minutes in the oven.

The crust dough can be chilled for up to 48 hours, wrapped tightly in plastic. The lemon curd keeps for 5 days in the fridge or 3 months frozen in an airtight container. The vanilla cream stays fresh for 3 days refrigerated, but it's best used within 24 hours for peak fluffiness. To assemble the pie, bake the crust for 15 minutes blind-baked, then fill and bake the curd for 12-15 minutes at 350°F. The cream layer goes on last and sets quickly—serve immediately for the best texture. Leftovers? Store the pie components separately to prevent sogginess, reassembling just before serving.

Step-by-step instructions for lemon supreme pie bakers Square copycat recipe

Master this iconic pie's signature layers—bright lemon curd, flaky crust, and velvety vanilla cream—using exact proportions and professional techniques.

In a food processor, pulse the 2.5 cups all-purpose flour with the 0.25 cup granulated sugar and 0.5 teaspoon salt until combined. Add the 1 cup cold cubed unsalted butter and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial—it ensures a tender, flaky crust.

Drizzle in the 0.5 cup ice water one tablespoon at a time, pulsing after each addition until the dough just comes together. Avoid overmixing—just until the dough forms a loose ball. Turn it out onto a lightly floured surface and gently shape into a 1-inch thick disk. Wrap tightly in plastic and chill for at least 1 hour (or up to 2 days).

Preheat your oven to 375°F. Roll out the chilled dough on a floured surface to fit a 9-inch pie dish, leaving a 1-inch overhang. Transfer to the pie dish and trim the edges, leaving the overhang intact. Prick the bottom all over with a fork to prevent puffing. Line with parchment paper, fill with pie weights or dried beans, and bake for 15 minutes.

Remove the weights and bake for an additional 10-12 minutes until the edges are golden brown and the crust is set. The bottom should be lightly browned but not dark. Let cool completely before filling—this prevents a soggy crust. I like to brush the bottom with a thin layer of lemon juice for extra zing.

In a medium saucepan, whisk together the 1.5 cups granulated sugar, 4 whole large egg yolks, 2 tablespoons cornstarch, and 2 tablespoons lemon zest until smooth. Slowly whisk in the 1 cup fresh lemon juice—this prevents curdling from the acid. Place the saucepan over medium-low heat and cook, stirring constantly, for 8-10 minutes.

Continue cooking until the mixture thickens enough to coat the back of a spoon and reaches 170°F on an instant-read thermometer. Strain through a fine-mesh sieve into a clean bowl to remove any zest bits. Press plastic wrap directly onto the surface to prevent a skin from forming, then chill for at least 2 hours. This cooling step is essential for the proper texture when assembled.

In a medium saucepan, combine the 1 cup whole milk and 1 teaspoon vanilla extract. Heat over medium heat until steaming but not boiling (180°F), about 5 minutes. In a separate bowl, whisk together the 0.5 cup powdered sugar and 4 whole large egg whites until pale and slightly thickened.

Slowly pour the hot milk mixture into the egg whites while whisking vigorously. Return the combined mixture to the saucepan and cook over low heat, stirring constantly with a wooden spoon, until it thickens enough to coat the spoon (160°F, about 3-4 minutes). Transfer to a bowl, press plastic wrap directly on the surface, and chill for at least 2 hours until completely set. This creates the signature fluffy texture that distinguishes this pie.

Spread the chilled lemon curd evenly over the cooled crust, leaving a ½-inch border around the edges. Spoon the chilled vanilla cream over the lemon curd, spreading it evenly with a spatula. Use a skewer to create decorative swirls if desired. Sprinkle any remaining lemon zest on top for extra brightness.

Return the pie to the refrigerator and chill for at least 4 hours (overnight is best). This long chilling time allows all the layers to set properly and the flavors to meld. When ready to serve, slice into perfect squares using a sharp knife dipped in hot water and wiped clean between cuts. The result should be a harmonious balance of tart lemon, sweet cream, and buttery crust in every bite.

Pro cooking tips for this dish

Crust Perfection

For a flaky, golden crust that holds up to the tangy filling, I swear by the "blind-baking" technique. Pre-bake the crust with pie weights or dried beans at 375°F for 15 minutes before removing them and baking another 10-12 minutes.

This prevents a soggy bottom—my biggest pet peeve! 🔥 Use a 9-inch pie dish and roll the dough to a 1-inch overhang for that bakery-style edge. I like to brush the bottom with lemon juice before adding the filling for extra zing.

Lemon Curd Secrets

The lemon curd needs constant stirring over medium-low heat to avoid scorching. Use a fine-mesh sieve to strain out zest bits for a silky texture. The curd is done when it coats the back of a spoon and hits 170°F—this ensures it sets properly without being grainy.

Chill it for at least 2 hours before assembling; this step is non-negotiable for that smooth, glossy finish. 💛

Vanilla Cream Tricks

For the vanilla cream, heat the milk to 180°F—not boiling—to prevent curdling the egg whites. Whisk the egg whites and sugar to pale ribbons before slowly adding the hot milk. Cook until it reaches 160°F, then press plastic wrap directly on the surface to prevent a skin.

Chill for at least 2 hours for that light, airy texture that sets this pie apart.

Assembly Like a Pro

Spread the lemon curd evenly, leaving a ½-inch border for the cream. Use a skewer to create swirls in the cream—this adds visual appeal and ensures even distribution. Chill the pie for 4+ hours (overnight is best) to let the flavors meld.

Slice with a hot knife for clean cuts—dip it in hot water, wipe dry between slices. 💡

Temperature Control

Bake the lemon curd layer at 350°F for 12-15 minutes—this gentle heat prevents cracking while ensuring it sets properly. The vanilla cream stays stable at room temperature for 1-2 hours before assembly, but it’s best used fresh for maximum fluffiness.

If your kitchen runs hot, reduce the oven temp to 325°F to avoid overbrowning the crust.

Make-Ahead Magic

Assemble the pie a day ahead—this is key for the layers to set perfectly. Store components separately in the fridge: crust (up to 48 hours), curd (5 days), and cream (3 days).

Reassemble just before serving to keep the cream light. For a busy schedule, bake the crust and curd layers the day before, then add the cream and chill overnight. ✨
