Prepare the Ingredients: Wash and core the apple, then slice it into smaller chunks. Rinse the spinach leaves thoroughly.
Blend It All Together: Add the apple, spinach, and almond milk into a blender. Blend on high for 30–45 seconds until smooth and creamy.
Adjust and Refresh: Taste and adjust thickness by adding more almond milk or a few ice cubes for a cooler, lighter texture.
Serve Fresh: Pour into glasses and enjoy immediately while cold and frothy.
Optional Add-Ins: Add a teaspoon of honey or chia seeds for extra sweetness and nutrition.
