In a high-speed blender, combine 1 cup of pumpkin puree, ½ cup of Greek yogurt, and 1 tablespoon of honey or maple syrup. Add 1 teaspoon each of cinnamon and nutmeg, alongside 1 cup of milk (dairy or non-dairy) for creaminess. Blend on high for 30-45 seconds until the mixture is completely smooth.

Once blended, check the texture. If a thicker consistency is desired, add a handful of ice cubes and blend for an additional 20 seconds. Adjust sweetness or spices as preferred, blending again briefly.

Pour the smoothie into a glass. For a smoothie bowl, reduce liquid slightly and top with garnishes like granola, sliced fruits, or a sprinkle of cinnamon.
