Expert Tips for Keto Peanut Butter Mousse

• Perfect Whipping: Ensure the heavy cream is beaten to stiff peaks for that airy mousse texture. Under-whipping can lead to a dense outcome.
• Room Temperature Cream Cheese: Softened cream cheese mixes better, preventing lumps. Take it out of the fridge at least 30 minutes before use.
• Gentle Folding: When combining the whipped cream and peanut butter mixture, fold gently to preserve the lightness of your mousse. Avoid vigorous stirring.
• Keto Chocolate Choice: Double-check that your chocolate chips are sugar-free to stay true to the keto peanut butter mousse theme. Regular chocolate can undermine your efforts.
• Adapt for Allergies: If using nut butters for substitutions, ensure they are low-carb and suitable for your dietary needs. Sunflower butter is a fantastic alternative!
