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.

I rarely bake or make desserts, but had the limes and gave this recipe a shot. I read the post three times trying to find the instructional photos and tips mentioned at the beginning- I never found any. I read the comments about the crust, which were helpful. The dessert turned out tasty. I did bake the crust at 325 degrees (pyrex), and increased to 350 with the custard, because the instructions weren’t clear to me. Outside of being shocked that I actually made a dessert, I liked that the bars weren’t a fakey green color. Excited to make these for a get together now!

Just out of the oven. Look and smell good except the top is pocked marked, like small bubbles that had popped. Don’t think I over whisked the filling. Is that how it’s to look?
