Easy Lemon Squares Recipe
Introduction
These easy lemon squares are a delightful balance of tart and sweet with a buttery shortbread base. Perfectly refreshing and simple to make, they are a great treat for any occasion.

Ingredients
- ½ cup butter (softened)
- ¼ cup powdered sugar
- 1 cup flour
- 1 pinch salt
- 2 large eggs
- 1 cup granulated sugar
- ½ teaspoon baking powder
- 3 tablespoons lemon juice
- 1 pinch salt
- Zest of ½-1 lemon (½ – 1 tablespoon)
Instructions
- Step 1: Preheat your oven to 350°F (180°C). Lightly grease and flour an 8×8 inch (20×20 cm) square cake pan or line it with parchment paper for easy removal.
- Step 2: Make the shortbread base by beating the softened butter and powdered sugar in a medium bowl on medium speed until combined. Add the flour and beat until a soft dough forms, about 1½ minutes.
- Step 3: Press the dough evenly into the bottom of the prepared pan. Bake for 18-20 minutes, then remove from the oven but keep the oven on. Allow the crust to cool before adding the filling.
- Step 4: In a separate bowl, beat together the eggs, granulated sugar, baking powder, lemon juice, a pinch of salt, and lemon zest. For a firmer filling that won’t sink, you can add 3-4 tablespoons of all-purpose flour if desired.
- Step 5: Pour the lemon filling over the cooled crust and return the pan to the oven. Bake for 20-25 minutes, or until the center is set. Baking time may vary slightly, so keep an eye on it.
- Step 6: Let the lemon squares cool completely in the pan. For easier slicing, chill in the refrigerator for about 1 hour. Cut into squares, dust with powdered sugar, and serve.
Tips & Variations
- For an extra lemony punch, increase the lemon zest to 1 tablespoon and add a little more juice.
- If you prefer a less sweet dessert, reduce the granulated sugar in the filling by 2 tablespoons.
- Line the pan with parchment with overhang on the sides; this makes removing the squares cleaner and easier.
- Adding a tablespoon of cornstarch to the filling can help stabilize it for a firmer texture.
Storage
Store leftover lemon squares in an airtight container in the refrigerator for up to 4 days. They also freeze well—wrap in plastic wrap and place in a freezer-safe container for up to 2 months. Thaw in the fridge before serving. For best flavor and texture, enjoy chilled or at room temperature.

FAQs
Can I use bottled lemon juice instead of fresh?
Fresh lemon juice is best for bright, natural flavor, but in a pinch, bottled lemon juice will work. Just be sure it’s 100% lemon juice without added sugars.
Why did my lemon squares turn out runny?
This often happens if the filling isn’t set completely before removing from the oven. Make sure to bake until the center is firm and consider adding a few tablespoons of flour or cornstarch to help thicken the filling.

Ingredients
Shortbread Base
- ½ cup butter (softened)
- ¼ cup powdered sugar
- 1 cup flour
- 1 pinch salt
Lemon Filling
- 2 large eggs
- 1 cup granulated sugar
- ½ teaspoon baking powder
- 3 tablespoons lemon juice
- 1 pinch salt
- Zest of ½–1 lemon (½ – 1 tablespoon)
- Optional: 3-4 tablespoons all-purpose flour (to prevent sinking filling)
Instructions
- Prepare the Pan: Preheat your oven to 350°F (180°C). Lightly grease and flour an 8×8 inch (20×20 cm) square baking pan or line it with parchment paper for easy removal.
- Make the Shortbread Base: In a medium bowl, beat the softened butter and powdered sugar on medium speed until well combined. Add the flour and salt, and beat until a soft dough forms, about 1 ½ minutes. Spread and pat this dough evenly across the bottom of the prepared pan.
- Bake the Base: Bake the shortbread crust in the preheated oven for 18-20 minutes until lightly golden. Remove from the oven and let it cool while you prepare the filling, but keep the oven on.
- Prepare the Lemon Filling: In another bowl, beat together the eggs, granulated sugar, baking powder, lemon juice, a pinch of salt, and lemon zest until well combined. If concerned about the filling sinking, stir in 3-4 tablespoons of all-purpose flour at this stage.
- Assemble and Bake: Pour the lemon filling over the cooled shortbread crust. Return the pan to the oven and bake for 20-25 minutes, or until the center is set. The top should be firm but slightly jiggly in the middle.
- Cool and Serve: Allow the lemon squares to cool completely in the pan. For easier cutting, chill the baked squares in the refrigerator for at least 1 hour. Cut into squares, dust with powdered sugar, remove from the pan, and serve. Enjoy your tangy and sweet lemon squares!
Notes
- To prevent the filling from sinking, adding 3-4 tablespoons of flour to the lemon mixture is recommended.
- Using fresh lemons for juice and zest greatly enhances the flavor.
- Chilling the lemon squares before cutting makes slicing cleaner and easier.
- Ensure the shortbread crust is fully cooled before adding the filling to avoid mixing or soggy texture.
- These squares can be stored in an airtight container in the refrigerator for up to 3 days.
