Key Lime Bars

I am in charge of the food for yet another women’s event at church.

This time we are doing a dessert bar with an assortment of bar cookies.  That means I’ve been trying out a lot of bar cookie recipes lately.  This could add a lot of extra calories to the old caloric intake but I have been pretty good about only eating a couple myself – for research and then giving the rest away!  But I must admit that I ate more than just a couple of the bar recipe I am sharing today – it was so yummy.

I am trying to balance the flavors for the dessert bar and I knew I  needed at least one citrus flavored bar cookie.  I have done my yummy lemon cheesecake bars several times at church events so I couldn’t do those again.  It would kind of be like wearing the same outfit to church two weeks in a row!

Since I had done lemon I decided lime would be perfect.  I found a recipe for key lime bars in a Land O’Lakes Best of Baking magazine.  I have found a couple of other great recipes out of the same magazine.  Unfortunately for all of you the magazine is a couple of years old and no longer available but lucky for you I’m sharing!


The recipe calls for key lime juice.  Key limes are smaller limes, about the size of a ping pong ball and not quite as green as the bright green Persian limes you usually find in the store.  I couldn’t find fresh key limes at the store but I did find bottled key lime juice.  The brand was Nellie & Joes.  If you can’t find fresh key limes or bottled key lime juice just use regular limes.  There is a slight flavor difference but the regular limes will be fine.  If you use the bottled key lime juice buy a regular lime too so you can grate the lime peel to put on top.  It’s so pretty!


The original recipe was for a 8 or 9 inch square pan but I changed it a bit to work for a 9 x 13.  I one and a half times the recipe but after making them I wish I had doubled the filling part of the recipe so the recipe below reflects that change.

The great thing about the bars is that they were yummy the day I made them but even better the second day!  Like I said I ate more than my share!!  The recipe is a definite keeper and will be part of our dessert bar line up!

    Just like Kirsty, my mouth was watering when I read the recipe. I copied the recipe to make. If you kept eating them, they must have been extra good! Whoever picked you to be incharge of the church events with food, knew
    what they were doing! Lucky recipients! :-)
    Thanks for the recipe Leigh Anne!

    Ms. Leigh Anne –
    A few times each year I buy a Key Lime Bar from the New Seasons dessert counter. Then I try to come home and replicate it. To no avail. I’m so excited to try these out. Yum yum.

    Leigh Anne,
    had to pop over here this morning and let you know I made the Key Lime Bars last night before I had to run to church for childcare. So they were sitting there waiting for my hubby when he got home from work. They are SOOOO yummy. I did find the Nellie and Joe’s Key Lime Juice at our local Wal-Mart. thanks!
    I could not wait to make them. :-)
    Thanks for the delicious recipe!!! Another keeper. My daughter loves them.

    OK, just made the bars this weekend. I have to confess, that I am fairly certain that so far I have eaten MYSELF 1/3 of the entire 13×9 pan. Yes it is true! I have hidden them in the oven so that they would not dry out, but I really think I hid them there so I could eat the rest of the 2/3 left! I will never make these again UNLESS I have an event to take them to or will eat only one and then wrap them up “pretty” and give them away! They are to DIE FOR!

    I love lime, so these were right up my alley. They are so good! I love the addition of the nuts in the crust.

    I served the Key Lime Bars last night to dinner guests. They really liked them and asked for the recipe. Can’t stop eating the left overs. Oh dear!
