Why You'll Love This Recipe
About the Ingredients
1 1/2 cups (190g) all-purpose flour
Provides structure for the crust. For a gluten-free version, use a 1:1 gluten-free flour blend.
1/2 cup (60g) powdered sugar
Adds sweetness and tenderness to the crust. You can use granulated sugar, but powdered gives a finer texture.
3/4 cup (170g) unsalted butter, cold and cubed
Creates a flaky, shortbread-like crust. Use cold butter for best results; if you only have salted, reduce added salt.
1/4 teaspoon salt
Enhances the flavors. Omit if using salted butter.
4 large eggs
Bind the filling and give it structure. For a richer version, use 3 eggs plus 2 yolks.
1 1/2 cups (300g) granulated sugar
Sweetens the filling. You can reduce to 1 cup for a tarter lemon flavor.
1/2 cup (120ml) fresh lemon juice (about 3-4 lemons)
Provides bright, tangy flavor. Always use fresh, not bottled, for the best taste.
2 tablespoons lemon zest
Adds aromatic citrus oils. Grate only the yellow part, not the white pith.
1/4 cup (30g) all-purpose flour
Thickens the filling. You can substitute with cornstarch for a gluten-free option.
1/2 teaspoon baking powder
Helps the filling rise slightly and become airy. Ensure it's fresh for best results.
Tips & Tricks
Use fresh lemon juice
Bottled juice lacks the bright, fresh flavor. Roll the lemons on the counter before juicing to get more juice.
Don't overmix the crust
Mix until just combined; overworking develops gluten and makes it tough. Press it evenly into the pan.
Cool completely before cutting
The filling needs time to set. Chill in the refrigerator for at least 2 hours for clean, neat squares.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prepare Pan
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides.
2. Make the Crust
In a medium bowl, whisk together flour, powdered sugar, and salt. Cut in cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Press firmly into the bottom of the prepared pan.
3. Bake the Crust
Bake for 15 minutes, until the edges are lightly golden. Remove from oven and set aside. Keep the oven on.
4. Mix the Filling
In a large bowl, whisk eggs and granulated sugar until smooth. Add lemon juice, zest, flour, and baking powder; whisk until well combined and no lumps remain.
5. Pour Over Crust
Pour the filling over the hot crust. It's okay if the crust is warm; this helps the filling set.
6. Bake the Filling
Bake for 20-25 minutes, until the center is set and the edges are lightly golden. The filling should be slightly jiggly in the center; it will firm up as it cools.
7. Cool and Chill
Let cool completely on a wire rack, then refrigerate for at least 2 hours to set fully.
8. Cut and Serve
Using the parchment overhang, lift the slab onto a cutting board. Slice into 16 squares with a sharp knife, wiping the blade between cuts. Serve chilled or at room temperature.
Delicious Variations
Lime Squares
Substitute lemon juice and zest with lime for a tropical twist.
Berry Swirl
Gently swirl 1/2 cup of raspberry or strawberry jam into the filling before baking.
Coconut Crust
Replace 1/4 cup of flour in the crust with shredded coconut for a nutty flavor.
How to Store Creamy Lemon Squares
Refrigerator
Store in an airtight container in the refrigerator for up to 5 days. Place parchment paper between layers to prevent sticking.
Freezer
Freeze squares in a single layer on a baking sheet, then transfer to a freezer-safe container. They keep well for up to 3 months.
Reheating
Enjoy chilled or at room temperature. If you prefer warm, microwave a square for 10-15 seconds, but they are traditionally served cold.
Frequently Asked Questions
Q: Why are my lemon squares runny?
Runny squares usually mean they were underbaked. The filling should be set around the edges but slightly jiggly in the center when you take them out; they will firm up as they cool. Also, ensure you measure the flour correctly and bake for the full time.
Q: Can I use bottled lemon juice?
Yes, you can, but fresh lemon juice gives a brighter, more authentic flavor. Bottled juice may also contain preservatives that can affect the texture. For best results, use fresh lemons.
Q: Can I make these gluten-free?
Absolutely! Use a 1:1 gluten-free flour blend for both the crust and the filling. The texture will be slightly different but still delicious.
Q: How do I get clean, neat cuts?
Chill the squares thoroughly before cutting. Use a sharp knife and wipe it clean with a damp cloth between cuts. This gives you neat edges.
Q: Can I reduce the sugar?
Yes, you can reduce the sugar to 1 cup for a tarter lemon flavor. Keep in mind that sugar also affects the texture, so don't reduce it too much or the filling may not set properly.
I hope you enjoy making these Creamy Lemon Squares as much as I do. Share them with loved ones, and remember: every bite is a little moment of peace. Breathe in, breathe out.
