These fluffy Keto Lemon Mousse jars are the perfect low-carb treat. So refreshing, yet so creamy. Velvety smooth and whizzed up in a matter of minutes.

Great for if you have friends over and need a crowd pleasing low-carb dessert with minimal fuss but maximum taste, or simply want a quick well earned treat to snuggle down to Netflix with.

Here's a tip if you love orange. Simply replace the lemon juice and zest with orange juice and zest, and optionally add a pinch of cinnamon!
