STEP-BY-STEP INSTRUCTIONS
- Prepare Ingredients: Gather 1 cup heavy whipping cream, ½ cup peanut butter (natural, no sugar added), 3 tbsp powdered erythritol or preferred keto sweetener, and 1 tsp vanilla extract.

- Mix Peanut Butter & Sweetener: In a separate bowl, blend peanut butter, sweetener, and vanilla extract until smooth and creamy.
- Fold & Combine: Gently fold the whipped cream into the peanut butter mixture. Maintain airiness by folding slowly until fully combined but not deflated.
