Zesty, vibrant lemon filling sits on a rich shortbread base in these must-try squares that nail the sweet-tart balance perfectly. Every mouthful offers a delightful mix of the crunchy bottom and smooth topping, making a light treat that adds sunshine to any table. These treats showcase beautiful simplicity, needing just a few everyday items to whip up something truly special.

I stumbled on this gem while hunting for the ideal dessert for my kid's outdoor party years back. After testing loads of different versions, this one stuck as our household favorite, earning a forever spot in our family cookbook. Even my hard-to-please mother-in-law asked me how to make them.

Essential Base Elements

  • Unsalted Butter: Go for good butter that's softened for the most flaky, tasty base.
  • Confectioners' Sugar: Gives you a softer feel than regular sugar would.
  • All-Purpose Flour: Scoop it with a spoon into your cups then level off for best results.
  • Salt: A small pinch works magic to lift all flavors and cut through sweetness.

Smooth Topping Components

  • Egg Yolks: They make a thick, pudding-like topping with gorgeous yellow tones.
  • Sweetened Condensed Milk: Adds sweetness and smooth texture without needing to add any cream.
  • Fresh Lemon Juice: Always squeeze your own lemons for the punchiest, most real flavor.

Making Amazing Citrus Squares

Base Building:
Start with butter that's sat out a while so it mixes well with sugar. Don't overwork your dough once you add flour or it'll get tough, then gently push it into your pan without pressing too hard.
Topping Tricks:
Beat your egg yolks really well before you mix in other stuff for the smoothest topping. The mix will start to thicken when you stir lemon juice into the milk - that's exactly what you want before baking.
Baking Tips:
Keep an eye on your base while it bakes first to get it golden but not dark. Your topping should look set but wiggle just a bit in the middle when done.
Cooling Know-how:
Let your squares cool down naturally before putting them in the fridge. This slow cooling stops water drops forming on top and helps get the texture just right.

As a kid, my grandma had a lemon tree right outside her house. Every spring, we'd pick the brightest ones and spend the day making these squares together. She showed me how rolling the lemons on the countertop before squeezing them gets more oil out, making the dessert taste much stronger.

Impressive Presentation

Show off these pretty squares on a white dish with a light dusting of powdered sugar. For fancy times, throw on some thin lemon slices and fresh mint for decoration. Serve them cool from the fridge for the best taste contrast.

Tasty Twists

Switch up these classic squares by tossing in some fresh blueberries to the filling before you bake it, adding lovely color pops and flavor. For more interesting citrus notes, try mixing your lemon juice with lime or even fancy blood orange juice.

Keeping Them Fresh

Store them in the fridge in a sealed container with parchment paper between layers so they don't stick together. They'll stay good for about three days, though at my house they're usually gone way before that.

Through all my years of baking, I've found that often the most basic treats leave the biggest mark. These citrus squares, with their just-right mix of flavors and textures, have shown up at so many family events. From casual Sunday dinners to fancy get-togethers, they always make folks happy with their bright taste and pretty look. The secret's in using good stuff and paying attention to the little things - sometimes the oldies really are the goodies.

Recipe FAQs

→ Can I use store-bought lemon juice?
Fresh juice works best for flavor, but if you're in a hurry, bottled juice can do the job. Expect a less vibrant taste though.
→ Why does my base feel too tough?
Overmixing or baking it too long is likely the cause. Combine ingredients gently and keep an eye on the oven timer!
→ How early can I make them?
Go ahead and make them up to 3 days before serving. Keep in the fridge and cut them fresh for clean slices.
→ Why won’t my topping set?
It probably needs longer to bake or a bit more time to cool completely. Check if the topping is firm before slicing.
→ Are they good for freezing?
Absolutely! Wrap tightly and freeze for up to a month. Let them thaw in the fridge and dust with sugar before serving.

Ingredients

→ For the Crust

01 1 cup all-purpose flour, measured and leveled
02 1/4 teaspoon salt
03 1/2 cup powdered sugar, with extra for dusting
04 1/2 cup (1 stick) unsalted butter, softened

→ For the Filling

05 3/4 cup freshly squeezed lemon juice (around 3 lemons)
06 4 egg yolks, large

Steps

Step 01

Preheat your oven to 350°F. Grease an 8-inch square pan, line it with parchment paper so it hangs over the edges, and grease it again.

Step 02

Cream together butter, powdered sugar, and salt until it’s light. Add flour and mix till just combined. Spread the dough into the pan, making sure it goes 1/2 inch up the edges. Poke it all over with a fork and bake for 15-20 minutes or until lightly browned.

Step 03

Stir egg yolks, condensed milk, and lemon juice until smooth. Pour it right over the crust while it’s still warm.

Step 04

Pop it back in the oven and bake for another 25-30 minutes until the filling sets completely.

Step 05

Let it cool in the pan first, then move it to the fridge and chill for at least 2 hours till it’s firm.

Step 06

Use the parchment paper to lift it out of the pan. Chop it into 16 pieces and sprinkle some powdered sugar on top before serving.

Notes

  1. Freshly squeezed lemons will give you the best taste.
  2. Don’t overwork the crust dough or it’ll get too hard.
