Ingredient Notes & Substitutions

Sweetener Options: Powdered erythritol or monk fruit blends work best for smooth texture. Avoid granulated sweeteners as they can make the mixture grainy.
Cream Cheese Tip: Always use full-fat cream cheese for the creamiest fluff. Reduced-fat versions can be watery.
Flavor Twists: Replace lemon juice with lime for a tropical kick, or add a drop of almond extract for extra depth.
Toppings: Try crushed keto cookies, toasted coconut flakes, or sugar-free white chocolate shavings for an indulgent finish.
