Summer is the perfect time to make classic fruit desserts like Strawberry or Peach Pie. The fruit is perfectly in season, and they just make the best treats. Key Lime has to be on the list of those favorite Summer dessert. The lime flavor is tangy, tart and refreshing, plus these chilled bars are sure to keep you nice and cool!

Cheesecake Bars are easier to make than a classic cheesecake. Instead of worrying about an ice bath or any steps like that, you just pour the key lime filling into your crust and bake it for 50 minutes. The bars are also easier to serve to a crowd than a typical Key Lime Pie or cheesecake. The squares are easy to cut, mess-free, and the batch is a lot bigger so it’s perfect for a party!

You can serve the Key Lime Cheesecake Bars as simple as they are, or add some garnishes to them. For a fancier occasion slice the bars into squares before serving. Then right before you take the dish out, add a dollop of Whipped Cream and thin lime slices for decoration. 



  • Prep time: Take the cream cheese out of your fridge to soften. Preheat the oven and spray your pan with cooking spray. 
  • Crust: Put 24 graham crackers in your food processor and pulse until they’re broken into crumbs. If you don’t want to use a food processor, put the crackers in a plastic bag on your counter and use a rolling pin to break them apart. Combine the crumbs with sugar, and melted butter. Press the crumb mixture into the base of a 9×13 inch baking dish. Use your hands to press the crust into an even layer. 
  • Cheesecake batter: Add the cream cheese and granulated sugar to your stand mixer. Beat them together on high until the cream cheese is nice and fluffy. If you don’t have a stand mixer, put them in a large mixing bowl and use a handheld electric mixer to do the same thing. Lower it to medium speed before you add the eggs, sweetened condensed milk, vanilla, key lime juice, lime zest, and flour. Mix all the ingredients together until smooth.
  • Bake: Use a rubber spatula to spread the lime mixture over the crust and bake for 50-55 minutes. Wiggle the pan to make sure the cheesecake is firm. Then put the Key Lime Cheesecake Bars in the fridge to chill.

  • Crust: Instead of making a graham cracker crust, you can follow the same direction using vanilla wafers, oreo, or gingersnap crumbs. 
  • Lemon bars: To make lemon Cheesecake Bars just replace the lime juice in the recipe with lemon juice and the lime zest with lemon zest. 
  • Fruit: You can add other fruit flavorings to the recipe by adding fruit jam to the top. Swirl Strawberry or Blueberry Jam over the top of the cheesecake in a marbled pattern before baking. You could also top the bars off with fresh berries. 



  • Serve: Because of all the cream in the recipe, you shouldn’t leave it at room temperature for longer than 2 hours. 
  • Store: Put the Cheesecake Bars in an airtight container or cover them in aluminum foil to store them in the fridge. They’ll be good for up to 1 week. 
  • Freeze: You can also freeze the bars. Wrap each square individually in plastic wrap or separate them with parchment paper to store them in a freezer bag. They’ll stay good frozen for up to 3 months. Let them thaw in the fridge and then serve chilled.
