Super Easy Lime Bars. Using only 5 simple ingredients!

I make the lemon version of these lime bars all the time but with some leftover limes in the fridge needing to be used, this recipe was  the easiest and quickest way to turn them into something delicious.

I was so happy to find the lemon version of this cookie bar because with only 5 simple ingredients and a quick preparation time, it quickly became a household standard.

In our part of the world, it is so much less expensive to buy lemons or limes by the bag than by buying them individually.

We often pick up a 3 or 4 pound bag. If we are slow to use them in drinks or in simple salad dressings, they most often will now be turned into these yummy cookie bars.

These Lime Bars are great for the freezer too, so we often have them on hand to pull out at the last minute if someone drops by for coffee.

If you only have lemons on hand don’t hesitate to try these as Lemon Bars… It’s one of our most popular cookie bar recipes of the last 10 years.

Yield: 36 cookie bars

Super Easy Lime Bars

Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 1 hour

Super Easy Lime Bars. Using only 5 simple ingredients and a very quick preparation time, these refreshing lime bars are based on easiest and best lemon bar recipe I've ever tried in almost 40 years of baking.


For the pastry base

  • 1 cup cold butter, cut in small pieces
  • 1/2 cup sugar
  • 2 cups flour

For the lime layer

  • 1 1/2 cups sugar
  • 1/4 cup flour
  • 4 eggs
  • zest of two limes, very finely chopped
  • juice of 4 to 5 small limes, around 2/3 to 3/4 cup juice


To make the pastry base

  1. Using a pastry cutter or in a food processor blend together the butter sugar and flour.
  2. Press evenly into the bottom of a greased and parchment paper lined 9×13 inch baking pan.
  3. Bake for 20 to 25 minutes at 350 degrees F ( 325 degrees F if you are using glass bake-ware)

For the lime topping

  1. Simply whisk together the sugar flour, eggs, zest and lime juice until the sugar is dissolved.
  2. Allow the topping to sit for about 10 minutes before whisking together well again and pouring over the baked shortbread base.
  3. Bake at 350 degrees F for about another 20- 25 minutes or until the top is slightly browned and the custard appears to be set. The bottom should just be beginning to brown slightly at the top edges. Cool completely. Sprinkle with icing sugar when cool or try adding a meringue topping.

Haven’t made them yet. But it is a Cool Saturday morning here in North Bay, Ontario and I was looking for something to make, and lo and behold I received an email with this very square wanting me to make it. So this morning I will be making these along side your pound cake. Time for Christmas baking. Thank you for your tasty treats!

I was looking for a way to use up fresh limes and came across this recipe. Mine is on the cooling rack now, and they look and smell amazing. Helpful note: I was concerned about how "powdery" the shortbread base was, but as it turns out, it's supposed to have that texture. Really looking forward to tasting these once they've cooled!
