These key lime pie bars are very similar to our No-Bake Key Lime Pie Recipe but this key lime pie bars recipe has cream cheese in it and you do have to bake it for about 10 minutes.

Just like our No-Bake Key Lime Pie we think these key lime cheesecake bars are yummy served very cold, even frozen. While these bars have been baked they can soften and "melt" after a short while so we do recommend keeping them very cold to frozen.

Can you make Key Lime Cheesecake Bars Ahead of Time?

Yes you can, you can prepare it all ahead of time as these bars need time to chill in the fridge. You can also make the graham crust and filling and keep them separate until you're ready to assemble and bake the bars.

Can you freeze Key Lime Pie Bars?

Yes! In fact we like to keep and serve these key lime pie bars frozen. They will start to soften quickly at room temperature so serving them frozen delays that. We suggest not leaving them out long, although it has never been a problem for us as everyone tends to gobble them up quickly.

Key Lime Pie Bars - Delicious Summer Dessert

These key lime bars are the perfect spring/summer dessert to serve at any gathering. You don't have to slave over the oven, they are quick to assemble and baking time with the crust is in total is only about 20 minutes. So you can have that oven off in no time. The hardest part is waiting for them to chill for a few hours.

Key Lime Cheesecake Bars Filling

The filling for these Key Lime Cheesecake bars is creamy, refreshing, tart but not sour and just a delicious combination of flavors. Here's what's in the filling:

  • key lime juice
  • lime zest (can be from any type of limes)
  • cream cheese 
  • sweetened condensed milk
  • fresh whipped cream and toasted coconut for toppings (optional)

We added cream cheese to this recipe even though that's not typical for key lime pie. The reason we added it is to make bars a bit more solid to keep their consistency and stability and for extra creaminess.

Can I use other limes instead of key limes?

Yes you can but I do recommend that you use freshly squeezed limes and not bottled lime juice as the taste is not the same in my opinion. Unless you can find bottled lime juice that says it's key lime juice then you can try that.

Now doesn't that look easy peasy and what a delicious dessert any time of the year but especially in the warmer months. You can also finish with some more lime zest on top of the bars. I love it with the whip cream and the toasted coconut too.

  1. Hi Michelle,
    If you are lactose intolerant or vegan can you sub alternatives dairy free condensed milk and dairy free cream cheese and yield the same results?

    • Hi Tawana,

      Unfortunately I can't speak to that since I haven't tried using dairy free items for these. It's really difficult to say without trying it out first.

  2. I LOVE key lime pie, and this looks like a great way to enjoy that taste with a crowd of people. Yum!

    Thanks so much for joining the Grace at Home party at Imparting Grace. I'm featuring you this week!

  3. Michelle, this recipe looks amazing and perfect to make for summer entertaining. I am so excited to feature your post at the Tuesday Turn About link party this week. Thank you so much for sharing!
