👩‍🍳 How to Make Lime Bars (Step-by-Step)

1. Prepare the Oven

Preheat your oven to 350°F (175°C). Line a baking dish with parchment paper for easy removal.

2. Make the Shortbread Crust

Mix flour, powdered sugar, and salt
Add butter and combine until crumbly
Press evenly into the pan
Bake for 18–20 minutes, until lightly golden

👉 A firm crust is essential—it holds the creamy filling perfectly.

3. Prepare the Lime Filling

Whisk sugar and flour
Add eggs one by one
Stir in lime zest and juice
Mix until smooth and creamy

The filling should be light, slightly thick, and well combined.

4. Bake Again

Pour the filling over the hot crust
Return to oven for 18–20 minutes
Bake until the center is set (no jiggle)

👉 Pouring filling onto a hot crust helps it bake evenly.

5. Cool and Chill

Let cool at room temperature (1 hour)
Refrigerate for at least 2 hours

This step is crucial for clean slicing and the perfect texture.

6. Serve

Lift using parchment paper
Cut into squares
Dust with powdered sugar

Serve chilled for the best flavor and texture.
