Lemon Cheesecake Mousse
Ingredients
Equipment
Method
- Combine crushed graham crackers with melted butter (and sweetener if using). Press into dessert cups to make an even layer. Chill for a firmer crust.
- In a large bowl, whip heavy cream to soft peaks. Gradually add lemon liquid stevia and salt, then whip to stiff peaks. This gives mousse its smooth, fluffy texture.
- Blend softened cream cheese (or mascarpone) until smooth. Mix in lemon juice, zest, and pre-bloomed gelatin (water + gelatin). Blend on high until creamy.
- Use a spatula to gently fold whipped cream into the cheesecake base. Spoon or pipe over prepared crust using a piping bag or Wilton tool.
- Refrigerate 1–2 hours (or overnight). Top with fresh lemon zest, berries, sugar‑free whipped cream, or chocolate chips before serving.
