Let it cool completely on a flat surface or in the refrigerator.

Tips for Success

Here are some tips and tricks to help you make the best key lime shortbread bars recipe.

Use extra parchment paper that hangs over the sides for easy removal from the pan after they’re done baking.

Bake the sweet shortbread crust in a square baking pan to get thicker lime bars.

Use green food coloring to make the bars look more lime-y or leave it out for a pale yellow look instead.

If you want smaller bars, cut the squares down the middle before serving.

What Kind of Limes to Use

There are many different varieties of limes you can use to make this delicious recipe with fresh lime juice.

The regular Persian lime you find at the grocery store is a bit sweeter and larger than Key limes or Mexican limes, while key limes and Mexican limes are slightly more sour and are smaller.

If you can find them, they are generally preferred for making the lime curd filling for the lime layer because of their bright citrus flavor which makes these bars on the tart side.

Other Types of Crust for Lime Curd Bars

This lime bar recipe uses a combination of flower, confectioners’ sugar, and butter to form a buttery shortbread crust.

You can also use crushed cookies to create a sweet and crunchy layer instead of the shortbread base.

Or, try making a gingersnap crust, hazelnut crust, or one using graham crackers. All of these options make delicious bars.Simply crush them up and mix with melted butter. Then press into the bottom of the pan.

What’s the best way to cut key lime pie bars?

Cutting nice clean lines makes your lime bars beautiful and there are a couple of tricks to doing so.

We’ve all cut through a pan of brownies or other gooey dessert and ended up with jagged lines and brownies stuck to your knife. It’s possible to make clean cuts by using these steps next time.

The colder the better: Chill the bars for at least two hours before cutting into them with a sharp knife. If they’re still warm in the middle, they won’t cut as nicely.

Lightly coat the knife with oil: Another option is to pour a small amount of oil onto a paper towel and run the towel over the blade of a large chef’s knife. This will help keep the bars from sticking to the sides of the metal knife.

Use a plastic knife: If you don’t want to oil your knife, you can use a plastic knife instead. The plastic repels the lime filling and doesn’t allow it to stick as much as a regular knife.

How to Store

Wrap the lime bars in plastic wrap or keep them separated in an airtight container and store them in the refrigerator for up to one week.

You can eat them right from the fridge, or allow them to warm up slightly on the counter first.
