- 8 large eggs
- 1 cup (240ml) fresh lemon juice (from 4–5 lemons)

🛠️ Equipment
- 9” x 13” (23cm x 33cm) baking pan
- 2 large mixing bowls
- Whisk (preferred) or fork
- Wooden spatula or spoon (for crust)
- Microplane or fine grater

🥄 Step-by-Step Instructions
1. Prep
- Preheat oven to 350°F (176°C)
- Optional: Line pan with parchment for easy removal
2. Shortbread Crust
- Mix Dry Ingredients
- Combine flour, powdered sugar, and salt in a bowl
- Add Melted Butter
- Pour in melted butter
- Mix with a wooden spatula, spoon, or your hands until crumbly
- Press Into Pan
- Evenly press mixture into the bottom of your pan
- Bake
- Bake 20–25 minutes until edges are just golden
Tip
Use powdered sugar in the crust for a melt-in-mouth texture. For the filling, stick with granulated sugar for classic chew.
Mixing tools: Wooden spatula for crust; whisk (or fork if needed) for filling.
3. Lemon Filling
- Zest the Lemons
- Wash lemons
- Use a microplane or fine grater to remove only the yellow outer layer (the zest)
- Avoid the white pith—it’s bitter!
Info
Lemon zest = just the yellow skin, not the white pith. Zest before juicing for max flavor.
- Combine Sugar & Zest
- Rub zest into sugar with fingers to release oils
- Add Flour
- Stir in flour until evenly mixed
- Add Eggs
- Crack eggs into a bowl
- Whisk thoroughly until yolks and whites are fully combined
- A whisk is ideal for a smooth, lump-free filling. A fork works if you don’t have a whisk—just mix well!
- Add Lemon Juice
- Squeeze lemons for 1 cup juice
- Add to mixture and whisk until smooth
Tip
Mix eggs well before adding other ingredients. Overmixing can add air—just whisk until smooth.
4. Assembly & Baking
- Pour Filling on Hot Crust
- If the filling sat and separated, whisk well to recombine before pouring
- Bake
- Bake at 350°F (176°C) for 20–25 minutes (9” x 13” pan)
- Filling should jiggle like Jell-O, not slosh
Warning
If you pour separated filling, the bars may bake unevenly. Always re-whisk before pouring!
5. Cooling & Serving
- Cool completely at room temp, at least 2–3 hours
- Chilling for 8 hours or overnight is ideal—this improves texture and makes slicing easier
- Dust with powdered sugar just before serving
Tip
Chilling longer (up to 8 hours or overnight) is not only safe, but recommended for best results.
