Does confectioners sugar and powdered taste the same?

Yes, confectioners' sugar and powdered sugar are essentially the same thing. They are both finely ground granulated sugar.

The terms are often used interchangeably, though "confectioners' sugar" might be slightly more common in the US, while "powdered sugar" might be more common in other English-speaking countries.

The key difference is that confectioners' sugar typically contains cornstarch, which helps prevent clumping and gives it a smoother texture.

So, while they are essentially the same, there can be slight variations in texture and taste depending on the brand and specific formulation. However, for most practical purposes, you can use them interchangeably.
