The origin of the key lime pie has been debated for many years, with families having their own secret recipes. With Key Limes coming into season, how could we pass up the opportunity to turn it into a keto dessert!

Leftover Low Carb Key Lime Pie can be stored in the fridge for up to 1 week. The pie, without the whipped cream topping, can be frozen for up to 3 months and defrosted overnight in the fridge.

  1. I’ve made this recipe 4 times. It was great everytime. I use a different low carb sweetened condensed milk recipe each time and it gives it a different feel, but this is the base recipe I make and everyone loves it.

    • Hi HA,

      There is no alternative to the sugar-free condensed milk, there are no packaged versions that we are aware of.

      • Lol sorry, I should have clicked the link above. I just made a batch of the sugar-free condensed milk (amazing!) and the key lime pie. It’s just out of the oven, and I am so impressed by the results. This recipe will be my go-to dessert from now on!

  2. This might be a stupid question- but when it calls for 7 ounces of Almond meal- is that like 7 fluid ounces (as in I should measure in a measure cup) or 7 ounces in weight?

    Thank you!!
