Ingredients
For the Crust:
1.5 cups graham cracker crumbs
1/4 cup sugar
4 tablespoons melted and cooled butter
For the Filling:
1 can (14 ounces) of sweetened condensed milk
2 egg yolks
1/2 cup fresh lemon juice
Instructions
Step 1: Prepare the Oven and Baking Dish
Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that the oven reaches the ideal temperature for both the crust and filling to cook evenly.
Prepare the Baking Dish
Take an 8×8-inch baking dish and either grease it with butter or line it with parchment paper. Lining with parchment paper is especially useful as it allows you to easily lift out the lemon squares after baking, making slicing a breeze.
Step 2: Make the Graham Cracker Crust
Combine Crust Ingredients
In a medium mixing bowl, combine 1.5 cups of graham cracker crumbs, 1/4 cup of sugar, and 4 tablespoons of melted and cooled butter. Mix these ingredients until the mixture resembles wet sand. The graham cracker crumbs should be evenly coated with the butter and sugar.
Press the Crust Mixture
Evenly and firmly press this mixture into the base of your prepared baking dish. Use the back of a spoon or the bottom of a glass to ensure that it’s compacted well. This helps the crust hold its shape and provides a sturdy base for the creamy filling.
Bake the Crust
Place the baking dish in the preheated oven and bake for approximately 10 minutes, or until the crust turns a light golden brown. This step is crucial as it ensures that the crust will be crisp and hold together well when the filling is added.
Cool the Crust
Once baked, allow the crust to cool for at least 30 minutes. This resting period helps the crust firm up and makes it easier to spread the filling over it without disturbing the base.
Step 3: Prepare the Lemon Filling
Mix Egg Yolks and Condensed Milk
While the crust is cooling, prepare the lemon filling. In a separate mixing bowl, whisk together 2 egg yolks and 1 can (14 ounces) of sweetened condensed milk until the mixture is thoroughly combined. The condensed milk adds a rich sweetness that balances the tartness of the lemon juice.
Add Lemon Juice
Gradually stir in 1/2 cup of fresh lemon juice. Continue to stir until the mixture is smooth and well combined. Fresh lemon juice is key to achieving that vibrant, tangy flavor. Ensure there are no lumps and the filling is creamy.
Step 4: Assemble and Bake
Pour the Filling
Pour the prepared lemon filling over the cooled graham cracker crust, spreading it evenly with a spatula. This ensures that each bite has an equal amount of the luscious lemon filling.
Bake the Lemon Squares
Return the dish to the oven and bake for an additional 15 minutes, or until the filling is set and firm. The filling should not jiggle when you gently shake the dish. Overbaking can cause the filling to crack, so keep an eye on it towards the end of the baking time.
Cool and Set
After baking, remove the dish from the oven and allow it to cool completely. For best results, let it sit for at least 1 hour to fully set before slicing. This cooling period helps the filling firm up and makes cutting into squares much easier.
Step 5: Slice and Serve
Remove from Dish
If you used parchment paper, carefully lift the lemon squares out of the dish using the paper. If you greased the dish, use a spatula to carefully lift the edges.
Slice into Squares
Use a sharp knife to cut the dessert into 16 squares or as desired. For clean cuts, wipe the knife between each cut.
Garnish and Serve
Optional: Garnish with a sprinkle of lemon zest for an extra burst of citrus flavor. Serve the lemon squares chilled or at room temperature. They make a refreshing and delightful dessert, perfect for any occasion.
Variations and Substitutions
Gluten-Free Crust: For a gluten-free option, use gluten-free graham cracker crumbs or a combination of ground nuts and sugar for the crust.
Dairy-Free Filling: Substitute the sweetened condensed milk with a dairy-free version or coconut milk for a dairy-free alternative.
Different Citrus Flavors: Experiment with other citrus juices such as lime or orange for a twist on the traditional lemon flavor.
Add-Ins: Incorporate a handful of fresh blueberries or raspberries into the lemon filling before baking for a fruity variation.
