Add the vanilla ice cream, milk, chocolate syrup, and cocoa powder to a blender. Blend everything until smooth and combined. If you prefer a thicker milkshake, you can add more ice cream. If you want a thinner consistency, add a little more milk.
Taste the milkshake and adjust the sweetness and chocolate flavor by adding more chocolate syrup or cocoa powder, if desired.
Pour the chocolate milkshake into glasses, top the milkshake with whipped cream, chocolate shavings, or sprinkles for extra indulgence.
Whipped cream, Chocolate shavings or sprinkles
Serve the chocolate milkshake immediately while it's still cold and creamy. Use a straw or a long spoon to enjoy every sip.
