Step-by-Step Beginner-Friendly Instructions
1. Preheat the oven
Set your oven to 350°F (175°C) and line a 9×13 baking pan with parchment paper for easy removal later.
2. Make the crumb mixture
In a large bowl, mix flour, granulated sugar, brown sugar, salt, and baking powder. Pour in the melted butter and vanilla, then stir until the mixture forms soft crumbs.
3. Form the crust
Press about two-thirds of the crumb mixture firmly into the prepared pan to create an even crust layer.
4. Pre-bake the crust
Bake the crust for 10 minutes until it looks slightly set but not browned.
5. Prepare the lemon filling
While the crust bakes, whisk together the condensed milk, lemon juice, lemon zest, egg yolks, and vanilla. The mixture should look smooth and creamy.
6. Assemble the bars
Pour the lemon filling over the warm crust and spread evenly. Sprinkle the remaining crumb mixture over the top.
7. Bake until golden
Bake for 25–30 minutes, until the top crumbs are lightly golden and the filling is just set.
8. Cool completely
Let the bars cool in the pan for about 1 hour, then chill for 1–2 hours for clean slices. Cut into squares and enjoy! 🍋✨

❓ FAQ
Can I use bottled lemon juice?
Fresh lemon juice gives the brightest flavor, but bottled lemon juice works if that’s what you have.
Why are my lemon bars too soft?
They may need more chilling time. Refrigeration helps the filling fully set.
Can I make these ahead of time?
Yes! They actually taste better the next day after chilling overnight.
Do lemon bars need to stay refrigerated?
Yes. Because of the egg yolks and condensed milk filling, store them in the refrigerator.
