No bake Keto (Key) Lime Cheesecake (gluten-free, lactose-free)

I like cheesecake but don’t like bought ones. I have made this recipe several times, its easier than it appears and is always successful. The flavour is fresh and the texture is light and fluffy. I love the idea of hidden avocado and it adds to the structure of the dessert. We don’t have key limes here so I just used ordinary small limes. The dessert is very popular with everyone whose had it even if they don’t follow a keto diet. Here is the original recipe. Try it and it will become a favourite.

Note: the original recipe serves 1-2 people, I altered the the recipe online to make 6 portions.

Cracker crust:

  • 60g almond flour
  • 4 1/2 tsp powdered erythritol (I used a fine brown erythritol)
  • 3/4 tsp cinnamon
  • pinch of salt
  • 4 1/2 tsp butter, melted (I used a lactose-free butter)

Cheesecake filling:

  • 120g sour cream (I used a plant-based double cream instead as I don’t like sour cream)
  • 210g cream cheese, at room temperature (I used a lactose-free cream cheese)
  • 84g butter (I used a lactose-free butter)
  • 90g avocado
  • 1/2-3 tsp grated lime zest
  • 9-15 tsp fresh lime juice
  • 6-9 tbsp powdered erythritol ( I don’t like powdered erythritol so I used a fine brown erythritol and the texture was good)


For the crust:

  • Lightly toast the almond flour in a pan, over a medium heat, until golden and fragrant (around 2-4 minutes). (You can’t leave it unattended)
  • Put the toasted flour in a bowl, then mix in the erythritol, cinnamon, and salt.
  • Add melted butter, and mix until combined. Then press into a serving glass or dish.
  • Allow to cool to room temperature, then place in the fridge whilst you make the cheesecake filling.

Cheesecake filling:

  • In a bowl whip the sour cream (I used a plant-based double cream instead), then set aside.
  • In another bowl using an electric mixer, add the cream cheese and butter, and whip until combined.
  • Next add the avocado to the bowl, and mix until combined. (If it’s ripe its easy using a hand mixer or a processor)
  • Then add the lime zest, lime juice, and erythritol to taste. Limes can vary in flavour, start with the lower amount and add until you reach your desired taste. Note: flavours will continue to develop whilst chilling.
  • Fold in the whipped sour cream (whipped plant-based double cream) into the key lime mixture. Then spoon the cheesecake filing on top of the cracker crust.
  • Freeze for around 30-40 minutes, or chill in the fridge for a couple hours, ideally overnight. (3 hours was fine)
  • Optional: serve with more whipped sour cream (or double cream), and freshly grated lime zest. (I chose to just use freshly grated lemon zest)
  • Enjoy!!
