    Ingredients and substitutions for Key Lime Cheesecake

    • Graham crackers: Graham crackers with their whole wheat plain flavor are a perfect base for this cheesecake. If you cannot source graham crackers. A perfect substitute in equal measure is digestive biscuits which are very similar equivalent overseas or even a plain milk biscuit would work well here.
    • Cream cheese: The core of our creamy cheesecake is room temperature full fat cream cheese, this helps give us a light cheesecake that is easy to mix until smooth.
    • Sweetened condensed milk: Vital to most no bake cheesecakes, this full fat condensed milk doesnโ€™t just add sweetness but also helps set the cheesecake.
    • Eggs: As well as adding structure to the cake, the eggs will bind everything together so are essential.
    • Lime juice: The very core of this recipe is the lime juice which adds a bright and zesty flavor to the cheesecake filling.
    • Heavy cream: Whipping your cream to soft peaks gives this a nice and light topping, but you can sub with canned whipped cream here.

    See recipe card for quantities.

    FAQโ€™s for the best Key Lime Cheesecake

    Can I make Key Lime Cheesecake ahead of time?

    Absolutely! The cheesecake needs several hours chill time, so ideally you make it the day before serving with this best served within 24 hours of making.

    Can I substitute key lime juice with regular lime juice?

    Absolutely! Key limes can be difficult to obtain so you can substitute regular fresh or bottled lime juice in equal measure here.

    Notes

    • Graham crackers: Graham crackers with their whole wheat plain flavor are a perfect base for this cheesecake. If you cannot source graham crackers. A perfect substitute in equal measure is digestive biscuits which are very similar equivalent overseas or even a plain milk biscuit would work well here.
    • Cream cheese: The core of our creamy cheesecake is room temperature full fat cream cheese, this helps give us a light cheesecake that is easy to mix until smooth.
    • Sweetened condensed milk: Vital to most no bake cheesecakes, this full fat condensed milk doesnโ€™t just add sweetness but also helps set the cheesecake.
    • Lime juice: The very core of this recipe is the fresh lime juice which adds a bright and zesty flavor to the custard filling. Key lime juice is best, but you can replace with any other fresh lime juice.
    • Cake tin: A round spring form tin was used, however, a standard cake tin of similar size would also work well.

      Had to give this a go as Key Lime Pie is my favorite, but cheesecake a close second. This is a perfect combination of the two and just so creamy without being overly rich or sweet

      Made this with the surplus of limes I had lying around and couldn't be bothered baking anything. Well, this is so light and still a little zesty. Thanks so much!
