A delightful and creamy coffee shake with a hint of marshmallow sweetness.
Combine the chilled milk, instant coffee granules, and marshmallow cream in a blender.
Ensure the milk is well-chilled for a frothy texture.
Blend the mixture for about 30 seconds or until smooth and creamy.
Blend on high speed for a smoother consistency.
Pour the shake into a glass and serve immediately.
Garnish with a dollop of whipped cream or a sprinkle of cocoa powder for presentation.
