Step-by-Step: How to Make Creamy Lemon Squares
Step 1: Preheat & Prep
Preheat oven to 350°F (175°C)
Lightly butter an 8-inch square baking dish
Line with parchment paper, leaving a 2-inch overhang on two sides — for easy removal
Step 2: Make the Crust
In a bowl, mix:
Graham cracker crumbs
Sugar
Melted butter
Press mixture firmly into the bottom and 1 inch up the sides of the pan
Bake 8–12 minutes, until lightly golden
Let cool 30 minutes — don’t skip this!
Pro Tip: Use the bottom of a glass to press the crust — smooth and even.
Step 3: Make the Filling
In a large bowl, whisk together:
Sweetened condensed milk
Egg yolks
Fresh lemon juice
Lemon zest (if using)
Whisk until smooth and slightly thickened — about 1–2 minutes.
