The Story Behind Spirulina in Baking

Spirulina has been used for centuries as a nutrient rich ingredient, but recently it has found its way into modern baking for its natural color and subtle earthiness. Blue spirulina, in particular, gives that stunning ocean shade without artificial coloring. When blended into buttercream, it creates a vibrant yet natural look that transforms an everyday cookie into something special. Pairing it with white chocolate keeps the flavor profile smooth and balanced, allowing the color to shine without competing flavors.
