Irresistible 4-Ingredient Key Lime Pie Squares You'll Crave

Question 1

Can I use regular limes instead of key limes?

Accepted Answer

Absolutely! While key limes have that special floral tang, regular Persian limes work just fine in a pinch. You'll need about 4-5 standard limes to get 1/2 cup juice. The flavor will be slightly different (more straightforward citrus than floral), but still delicious. Just don't tell any Florida natives I said so!

Question 2

How long do these squares keep in the fridge?

Accepted Answer

They'll stay perfect for about 3 days when stored properly, just cover the pan tightly with plastic wrap or transfer to an airtight container. The crust might soften slightly by day 3, but in my experience, they never last that long anyway! Pro tip: If you need to make them ahead, prep the crust a day early and store at room temp, then add the filling the day of serving.

Question 3

Why is my filling not setting properly?

Accepted Answer

Oh no! Usually this means one of three things: 1) You didn't bake the filling long enough (those 15 minutes are crucial!), 2) You skipped the full 2-hour chill (I know, I know, but it's mandatory!), or 3) Your lime juice was watered down. Next time, try using a timer for both baking and chilling. Patience pays off with perfect squares!

Question 4

Can I make these without baking?

Accepted Answer

You sure can! For a no-bake version, skip the oven steps: just press the crust into the pan, mix the filling, pour it over, and chill for at least 4 hours. The texture will be slightly softer but just as tasty. I actually prefer baking because it gives the crust that toasty flavor, but both ways work when you're in a hurry.

Question 5

What's the best way to cut clean squares?

Accepted Answer

Here's my foolproof method: Dip a sharp knife in hot water, wipe it dry, then make your cuts. Repeat the hot water trick between each slice. The heat helps glide through the creamy filling without dragging. And always, ALWAYS wait until they're fully chilled, cutting too soon is the #1 reason for messy squares!
