Ingredients Method

Ingredients
  

  • Heavy whipping cream 1 cup: Creates light, airy texture
  • Cream cheese 8 oz, softened: Adds richness and body
  • Fresh lemon juice 3-4 tablespoons: Bright citrus flavor
  • Lemon zest 1-2 teaspoons: Intense aroma
  • Powdered keto sweetener ½ cup: Prevents graininess
  • Vanilla extract 1 teaspoon: Rounds out flavor
  • Salt ⅛ teaspoon: Balances sweetness

Method
 

Step 1 – Whip the Cream
  1. Beat cold heavy cream with a hand mixer until soft peaks form—about 2-3 minutes. Cold equipment works faster for this easy lemon mousse.
  2. Pro tip: Pop your bowl in the freezer for 10 minutes first. Don’t over-whip or cream gets grainy.
Step 2 – Mix the Lemon Base
  1. Beat softened cream cheese until fluffy—about 1 minute. Add sweetener, lemon juice, zest, vanilla, and salt. Beat until silky smooth.
  2. Pro tip: Strain through mesh if you have lumps for perfectly smooth lemon mousse.
Step 3 – Fold for Light Texture
  1. Gently fold one-third whipped cream into lemon mixture using a rubber spatula. Add remaining cream and fold until just combined—no white streaks.
  2. Pro tip: Ten gentle folds beat five aggressive stirs for this no bake lemon mousse.
Step 4 – Chill and Set
  1. Spoon into serving dishes, cover, and refrigerate 2-4 hours. For faster results, freeze 30-40 minutes.
