Ingredients for Old Fashioned Lemon Squares
- 1 cup all-purpose flour
- 1/2 cup powdered sugar
- 1/2 cup unsalted butter, softened
- 2 large eggs
- 1 cup granulated sugar
- 1/4 cup freshly squeezed lemon juice
- 1 tablespoon lemon zest
- 1/2 teaspoon baking powder
- Pinch of salt
Ingredient Notes and Substitutions
- All-purpose flour: Used for the crust, providing structure. You can substitute with gluten-free flour for a gluten-free version.
- Powdered sugar: Adds sweetness and helps create a tender crust. Granulated sugar can be used but will yield a different texture.
- Unsalted butter: Adds richness and flavor. If using salted butter, reduce the additional salt in the recipe.
- Granulated sugar: Sweetens the filling. Coconut sugar can be a great alternative for a different flavor profile.
- Lemon juice and zest: Essential for that refreshing lemon flavor. Lime juice can be used for a different twist.
How to Make Old Fashioned Lemon Squares
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures even baking and helps the crust become perfectly golden.
Step 2: Prepare the Baking Dish
Grease a 9×9 inch baking dish with butter or line it with parchment paper. This prevents sticking and makes for easy removal.
Step 3: Make the Crust
In a mixing bowl, combine 1 cup of flour, 1/2 cup of powdered sugar, and 1/2 cup of softened butter. Mix until crumbly and well combined.
Step 4: Press the Crust into the Pan
Press the mixture firmly into the bottom of the prepared baking dish. This forms a sturdy base for the lemon filling.
Step 5: Bake the Crust
Bake the crust in the preheated oven for about 15 minutes, or until lightly golden. This allows the crust to set before adding the filling.
Step 6: Prepare the Lemon Filling
In a separate bowl, whisk together the eggs, 1 cup of granulated sugar, 1/4 cup of lemon juice, lemon zest, baking powder, and a pinch of salt. This combination creates the tangy filling.
Step 7: Pour the Filling Over the Crust
Once the crust is baked, pour the lemon filling evenly over it. The filling will bubble up while baking, creating a delightful contrast.
Step 8: Bake Again
Bake for an additional 20 minutes, or until the filling is set and slightly firm to the touch. This step is crucial for achieving that perfect texture.
Pro Tip: Let the lemon squares cool completely before cutting them. This helps them hold their shape better!
