Notes

Absolutely feel free to make this even more protein heavy by adding in a scoop of your favorite vanilla protein powder.
Adjust milk amounts slightly for a thinner or thicker consistency.
Blue spirulina is purely for color and mild nutrients—it won’t taste “algae-like” at this amount.
Any sugar-free vanilla ice cream works here, dairy or plant-based.
Best enjoyed fresh for the brightest colors.
