Key ingredients

  • Cream cheese – Can’t be cheesecake without cream cheese! Cream cheese should be softened in order to cream it into a fluffy, silky texture the keto cheesecake mousse.
  • Sweetener – It’s preferred to use powdered sugar-free sweetener like a powdered erythritol or monkfruit blend in order to prevent a grainy texture that may occur with a granulated sweetener. The sweetener amount can be adjusted to your liking. Add more or less depending on how sweet you like it.
  • Lemon juice – Lemon juice is a necessary ingredient for cheesecake flavor. It helps to balance out the sweetness and brighten up the cheesecake.

As this keto recipe makes four servings, any leftover cheesecake fluff can be stored in the refrigerator for up to 3-4 days.

Another option is to freeze it! This will create almost an ice cream like texture but don’t try to thaw it and except it to have a similar mousse like texture as before. Once frozen, it’s best to eat it frozen.
