Tips for Success
- Deglaze your zest: Make sure to only zest the green part of the lime to avoid the bitter white pith.
- Temperature control: Let the cups sit at room temperature for 5 minutes before eating for the perfect creamy texture.
- Consistency check: If your protein powder is highly absorbent, add a splash of almond milk to reach a pourable consistency.

- Use cashew flour instead of almond flour for a nuttier, richer crust base.
