Deliciously awesome Key Lime Swirl Cheesecake Bars using fresh homemade lime curd or store bought lime curd.



  • 2 cups graham crackers or digestive biscuits, crushed
  • 1 stick/113g butter, melted


  • 1 stick/113g butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 2 large egg yolks
  • β…“ cup + 4 tbsp fresh lime juice


  • 2 8oz packs cream cheese, softened
  • Β½ cup granulated sugar
  • 2 large eggs
  • 1 large egg white
  • 2 tbsp plain/all purpose flour
  • Β½ cup sour cream
  • 1 tsp vanilla extract
  • green and yellow food colouring (liquid or gel)



  1. Beat butter and sugar into a large bowl. Slowly add the eggs and the yolks one at a time, mixing well after each addition. Pour in the lime juice and mix again. Expect the mixture to look curdled, this is normal.
  2. Cook the mixture over a medium heat in a medium-sized saucepan until it looks smooth and no longer curdled. Increase the heat slightly and cook, whisking constantly until the mixture thickens. Using a thermometer, cook until the mixture reaches 170℉/77℃.
  3. Remove the curd from the heat and transfer into a bowl. Press plastic wrap in the surface of the lime curd to keep a skin from forming. Chill the lime curd in a refrigerator, the curd will thicken more as it cools. It will keep in the fridge for approx. 2 weeks.


  1. Preheat the oven to 325℉/175℃, line a 10×10 inch pan with parchment that overhangs the edges. Mix the butter and graham crackers or digestive biscuits together and press into the bottom of the pan evenly. Bake the crust for 5 minutes and allow to cool completely.


  1. Tint ΒΎ of a cup of the lime curd with the green and yellow food colouring until a lime-rind green and set aside. Beat cream cheese and sugar in a large bowl with mixer on medium-high speed until smooth.
  2. Beat in eggs on low speed until blended then beat in the sour cream, vanilla and plain/all purpose flour until just blended. Remove 1 cup of batter and reserve.
  3. Pour the remaining batter over the crust. Mix Β½ cup of the tinted lime curd with 1 cup of the reserved batter. Place spoonfuls or dollops of this mixture, in no particular fashion, on top of the plain cheesecake batter. Repeat with the remaining ΒΌ cup lime curd onto the previous mixture. Using a skewer or toothpick, swirl the mixture together to create a marbled effect.
  4. Bake for 35 minutes at 325℉/170℃. Allow to cool completely in the pan then refrigerate. Once chilled, lift the cheesecake out of the pan with the parchment overhang and cut into bars before serving.


After I pressed the graham crackers/disgestive biscuits into the bottom of the pan and allowed to cool, I put the pan in the refrigerator to cool and harden further as it seemed a little too brittle not to do this.

    I’m totally the same way–pop me into a climate where the average temp is less than 80 degrees F and I will bust out the gloves and thermal socks. I love your defiance of autumn’s arrival, although I am a bit wary about bringing green dessert to my circle of friends! The last time I did that, my they asked me if I was trying to feed them moldy dessert. Um. No. And these look gorgeous imo (so if they don’t want to eat them, I sure will).

      Haha below 80℉? That’s 26℃ here and anything above 18℃/64℉ the weirdos in this country bust out the strappy tank tops and shorts, but not me! I’m so with you on that. You ought to have seen me 2 yrs back when I came back from 35℃/95℉ weather in Greece back to our ‘English’ summer weather, I had the heating on almost full blast with sweatshirts on!!

      The green colour is from the food colouring. I used gel as I didn’t want to water down the curd with liquid food colouring (even if it is a few drops). I only put 1 drop in but as we know, gel is uber concentrated. Perhaps leave out the food colouring and/or mix the lime curd into the batter so it won’t be green but still has the same taste? That would work and no ‘mouldy’ desserts (the cheek!) If anyone such a comment to me, I’d be like ‘ah well more for me then!’ :)

    I’m actually a winter-girl, but looking at these gorgeous bars I’m willing to change it….. :)
    It’s quite difficult to get lime here and I’m sure gonna try!:)

      Each to their own lol. There are a few things I like about winter, when it’s below freezing and walking the kids to school in the snow definitely wakes me up. But then again, I’m not that fond of the cold. English summers tend to be mild (understatement of the century!) so quite comfortable. I just hate all that rain inbetween.

    These look fabulous, Lisa. I LOVE key lime pie. Yum. I’ve pinned this for future reference. Thanks so much for sharing on Marvelous Mondays!
