Gather all the ingredients needed to create your delightful Cake Batter Milkshake.

In a blender, combine the softened vanilla ice cream, whole milk, dry yellow cake mix, rainbow sprinkles, and vanilla extract. Blend until smooth.

If the milkshake is too thick, slowly add milk until desired consistency is achieved.

Taste the shake; add more vanilla or powdered sugar for sweetness if needed.

Pour the mixture into a tall glass, allowing it to swirl beautifully.

Top with whipped cream and sprinkles for additional flavor and visual appeal.

Garnish with a maraschino cherry and any extra cake pieces for decoration.

Serve immediately while it's cold and frothy.
