The custard sets to a beautiful, smooth texture thanks to the simple yet clever use of eggs and sugar, while the crust provides a satisfying crunch that complements the creamy filling. It’s a dessert that feels fancy but is surprisingly easy to make, requiring no complicated techniques or exotic ingredients.

Plus, lemon chess squares are wonderfully versatile—you can dust them with powdered sugar, add a light glaze, or even a sprinkle of fresh berries for extra flair. They store well, travel well, and are sure to be a hit at any occasion, from casual family dinners to festive celebrations.

Ingredients

• 1 cup (2 sticks) unsalted butter, softened
• 2 cups all-purpose flour
• 1/2 cup granulated sugar (for the crust)
• 4 large eggs
• 2 cups granulated sugar (for the filling)
• 1/4 cup all-purpose flour (for the filling)
• 1/4 cup cornstarch
• 1 cup freshly squeezed lemon juice (about 4-5 lemons)
• 1 tablespoon lemon zest (optional, for extra lemon flavor)
• Powdered sugar for dusting

Equipment

• 9×13 inch baking pan
• Mixing bowls
• Electric mixer or whisk
• Citrus juicer or reamer
• Microplane or grater for zesting lemons
• Sifter for powdered sugar (optional)
• Parchment paper or non-stick spray
• Measuring cups and spoons
• Spatula

Instructions

1. Preheat your oven to 350°F (175°C). Line the 9×13 inch baking pan with parchment paper, allowing some overhang for easy removal later, or generously grease the pan.
2. Make the crust: In a mixing bowl, cream together the softened butter and 1/2 cup granulated sugar until light and fluffy. Gradually add 2 cups flour and mix until the dough comes together. It will be crumbly but should hold when pressed.
3. Press the crust evenly into the bottom of the prepared pan, making sure it’s compact and smooth. Bake for 15-20 minutes until lightly golden around the edges. Remove from oven and set aside.
4. Prepare the lemon filling: In a large bowl, whisk together the eggs and 2 cups granulated sugar until smooth and pale. Add 1/4 cup flour and 1/4 cup cornstarch, whisking until fully combined without lumps.
5. Stir in the freshly squeezed lemon juice and lemon zest (if using). Mix until the filling is smooth and consistent.
6. Pour the lemon filling over the warm crust immediately after removing it from the oven. Spread gently to cover the crust evenly.
7. Bake the assembled bars for 25-30 minutes, or until the filling is set and slightly jiggles when you gently shake the pan. The top should be a pale yellow with a faint golden tint.
8. Cool completely in the pan on a wire rack, then refrigerate for at least 2 hours to fully set the custard for clean slicing.
9. Lift the bars out of the pan using the parchment overhang, dust with powdered sugar just before serving, and slice into squares.

Tips & Variations

For a more intense lemon flavor, add an extra teaspoon of lemon zest or substitute half the lemon juice with lime juice for a citrus twist.

• Make it gluten-free: Substitute the all-purpose flour in the crust and filling with a gluten-free flour blend.
• Glaze option: Whisk powdered sugar with lemon juice to make a thin glaze and drizzle over cooled bars for extra sweetness.
• Berry topping: Add a layer of fresh blueberries or raspberries on top of the filling before baking for a fruity surprise.
• Storage: Keep leftovers refrigerated in an airtight container for up to 4 days. They also freeze well, just thaw before serving.
