Ingredients & Why They’re Keto

• 1 cup heavy whipping cream
  Heavy cream is naturally high in fat and very low in carbohydrates, making it an ideal ingredient for keto desserts. It creates the fluffy, cloud-like base of this mousse while also keeping you full and satisfied.

• 4 oz cream cheese, softened
  Cream cheese adds a rich, velvety texture and slight tanginess. It also provides healthy fats and protein with minimal carbs, making it a staple in keto dessert recipes.

• ¼ cup Keystone Pantry Allulose
  Allulose is a rare natural sugar that tastes like sugar but doesn’t spike blood sugar levels or impact net carbs. It dissolves easily, giving the mousse the perfect sweetness without any bitterness or aftertaste. This is what makes the recipe keto-friendly while still tasting like a traditional mousse.

• 1 tbsp lemon zest & 2 tbsp fresh lemon juice
  Lemon adds brightness and a refreshing tang that balances the richness of the cream and cream cheese. Fresh zest and juice also provide antioxidants and vitamin C.

• ½ tsp vanilla extract
  Vanilla enhances the overall flavor and smoothness of the mousse, tying together the lemon and berry notes.

• ½ cup mixed berries (optional for garnish)
  While berries do contain natural sugars, they are among the lowest-carb fruits available. When used sparingly as a garnish, they add a burst of flavor, color, and freshness without significantly increasing carbs.

Instructions

1. Whip the cream – In a mixing bowl, beat the heavy cream until soft peaks form. Set aside.
