The rich texture and mild lemon flavour will make you nosh these squares by the dozen. Dusted with icing sugar, the bars are perfect to serve with tea, or as a delicious present for all lemon lovers.

Creamy Lemon Squares Recipe
If you want to switch things up, replace the lemon juice and zest with the same amounts of freshly squeezed lime juice and zest.
Prep Time: 30 min
Freezing Time: 15 min
Oven Temperature: 175°C / 350°F / gas mark 4
Baking Time: 12 – 15 min + 15 – 18 min
Yields: 25 – 30 lemon squares
For the crust
- 150 g (2/3 cup) cold, unsalted butter
- 190 g (1 1/2 cups) all-purpose flour
- 85 g (2/3 cup) icing (confectioners’/powdered) sugar
- 1/2 tsp salt
For the filling
- 1 egg (UK & Europe: M / US, CA, AUS & NZ: L)
- 3 egg yolks
- 1 400 g (14 oz) tin (can) sweetened condensed milk
- 120 ml (1/2 cup) freshly squeezed lemon juice
- 1 tsp lemon zest
- icing (confectioners’/powdered) sugar
To grease the baking tin (pan)
- cooking or baking spray, oil or butter
- kitchen scale or measuring cups and spoons
- large mixing bowl
- dough hook
- 25 cm (10 in) square baking tin (pan)
- baking or parchment paper
- oven mitts or a kitchen towel
- cooling rack
- cutting board
1) Prep the baking tin
Coat the bottom and sides of a square baking tin (pan) with baking spray, oil or soft butter. Place a piece of baking or parchment paper on top, creating an overhang on two sides.
2) Mix the crust
Add the flour, icing sugar, salt and cold butter into a large mixing bowl. Create a crumbly texture using a dough hook. Fill the crumbs into the prepared baking tin (pan) and press crumbs firmly down until the entire bottom of the tin (pan) is evenly covered and no bare spots are showing.
3) Freeze and bake the crust
Place the baking tin (pan) into the freezer for 15 minutes. Meanwhile, preheat the oven to 175°C (350°F / gas mark 4). After 15 minutes, remove the tin (pan) from the freezer and bake the crust for 12 to 15 minutes.
4) Mix the lemon topping
While the crust is baking, mixing the lemon filling. In a large mixing bowl, whisk together the sweetened condensed milk, egg, and egg yolks until perfectly combined. Add the lemon juice and zest and continue whisking until well blended.
5) Bake the lemon squares
Remove the crust from the oven and pour the lemon filling on top. Reduce the heat to 160°C (325°F / gas mark 3), and bake for 15 to 18 minutes until the filling has set. Allow to cool on a wire rack
6) Cut and decorate the squares
Transfer the crust to a cutting board and cut into 4 cm by 4 cm (1.5 in x 1.5 in) squares. Dust the lemon squares with icing (confectioners’/powdered) sugar before serving.
Materials: lemons, sweetened condensed milk
Assemble the printable tab gift box
Print the two parts of the box on DIN A4 or letter size cardstock or photo paper and cut out all components along the grey lines. Using a blade knife cut out the small white strips in the larger flaps. Working with a bone folder and ruler, crease along the grey lines and fold all four edges of the box. Put glue on the flap that says “Glue” and adhere the side part to the box. You can either use double-sided tape, a strong glue stick, or super glue. Gently bend the opposite flaps to give them a curved shape. Fill the box with lemon squares and close by sliding the two sides with slits over the ones with the tabs.
Tip: We also printed the decorative pattern on the back of the printables, so the gift box looks pretty on the inside as well.
Shelf life & storage of the lemon squares
You can store the lemon squares refrigerated for up to 4 days in an airtight container – although we doubt they will even last this long. The lemon squares can also be frozen for up to a month.
