Easy Lemon Squares Recipe
Introduction
These easy lemon squares combine a tender shortbread crust with a zesty lemon filling for a bright, refreshing treat. Perfectly sweet and tangy, they make a delightful dessert or snack any time of year.

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 (20x20cm) square cake pan or line it with parchment paper.
- Step 2: For the shortbread base, in a medium bowl, beat the softened butter and powdered sugar on medium speed until combined. Add the flour and beat again until a soft dough forms, about 1½ minutes.
- Step 3: Pat the dough evenly into the bottom of the prepared pan. Bake for 18-20 minutes until lightly golden. Remove from the oven but leave the oven on. Let the crust cool before adding the filling.
- Step 4: For the lemon filling, in a medium bowl, beat together the eggs, granulated sugar, baking powder, lemon juice, pinch of salt, and lemon zest until smooth. If concerned about the filling sinking, optionally add 3-4 tablespoons of flour.
- Step 5: Pour the filling over the cooled crust. Return the pan to the oven and bake for 20-25 minutes, until the center is set. It may need the full 25 minutes or slightly longer depending on your oven.
- Step 6: Allow the lemon squares to cool in the pan. For easier cutting, chill them in the refrigerator for at least 1 hour. Cut into squares, remove from the pan, dust with powdered sugar, and serve. Enjoy!
Tips & Variations
- Adding a few tablespoons of flour to the lemon filling helps prevent it from sinking and creates a firmer texture.
- Use fresh lemon juice and zest for the brightest flavor—bottled lemon juice won’t give the same zing.
- For a more intense lemon flavor, increase the lemon zest to 1 tablespoon.
- Try topping with a light dusting of powdered sugar or a thin drizzle of glaze for extra sweetness.
Storage
Store the lemon squares in an airtight container in the refrigerator for up to 4 days. They can also be frozen for up to 1 month; thaw in the fridge before serving. Reheat slightly at room temperature if desired, but they are delicious served chilled.

FAQs
Can I use a different-sized pan?
You can use a slightly larger or smaller pan, but baking times may need adjustment. A smaller pan will yield thicker bars and require a longer bake, while a larger pan will make thinner bars and bake faster.
What can I substitute for butter?
Butter provides flavor and texture crucial for the shortbread base, but you can try margarine or a plant-based spread in equal amounts. Keep in mind this may slightly change the taste and consistency.
