Does powdered sugar taste the same when baked as granulated sugar?

No, they do not taste exactly the same when baked. Here are some of the differences:

1. Texture: Powdered sugar has a finer texture compared to granulated sugar. When baked, it can sometimes result in a smoother texture in the final product.

2. Aeration: Powdered sugar contains a small amount of cornstarch to prevent clumping. This cornstarch can introduce some lightness or aeration to baked goods.

3. Sweetness: Some people find powdered sugar to be less sweet than granulated sugar in baked goods. This could be due to the addition of cornstarch, as well as the fact that powdered sugar dissolves more easily, leading to a more gradual release of sweetness.

4. Color: Powdered sugar can give baked goods a slightly paler or whiter appearance compared to granulated sugar, especially when used in larger quantities.

Overall, while powdered sugar can be used as a substitute for granulated sugar in some baked goods, there may be slight differences in taste and texture to consider.
